Basics of Creating Feminized Seed
To produce all female seed requires induction of female plants to develop male flowers that produce pollen that will be genetically female.
Female sex chromosomes: XX
Male sex chromosomes: XY
So when a female plant (XX) is induced to form pollen, since there is no “Y” chromosome all of the resulting pollen will be XX (female).
When pollinated with a known female plant (also XX) this will result in the offspring being female (XX).
How To Induce Male Flowers on a Female Plant?
3mM Silver Thiosulfate (STS) applied as a foliar spray (on three occasions 7 days apart) to produce male flowers
The 3mM STS treatment was shown on four strains of female hemp (having a THC concentration of ≤0.3%), designated CBD hemp A, CBD hemp B, CBD hemp C, and industrial hemp.
Study Specifics (Materials and Methods)
Rooted cuttings were about 6 inches high with two shoots when foliar sprays of STS were initiated.
Silver thiosulfate solutions (0.3 and 3 mM) were prepared by mixing silver nitrate with STS in a molar ratio of 1:4, per Cameron and Reid (1981).
*See end of slide show for exact preparation steps of 3 mM Silver thiosulfate solution
Plants were sprayed to runoff (about 20 mL/plant) on three occasions, 7 days apart, beginning on 30 Apr. 2018 for the first replication and on 14 May 2018 for the second replication of this study.
Control plants received sprays of water only.
On 30 Apr. and 14 May, plants began receiving short-day conditions of about 8 h using a blackout curtain to initiate the flowering stage.
Study Results
Between 14 and 21 days after the first STS spray treatment, plants transitioned from first flowers to full flowering.
The most complete inflorescence conversion to male flowers occurred at 3 mM STS for all hemp strains.
At 3 mM STS, the majority of inflorescences had 100% male flowers and the remaining inflorescences had 75% male flowers.
Untreated control plants of all four hemp strains produced only female flowers, as expected
Reduced Pollen Production
Male flowers that developed on genetically female plants produced pollen.
However, the pollen did not appear to be as plentiful or freely released as observed on true genetically male plants.
The pollen did produce seed, which was harvested, germinated, and exposed to short-day conditions.
The resulting plants were confirmed to be female.
Possible Explanation for Mode of Action of STS
Ethylene blocking by STS is likely responsible for the production of male flowers on female hemp plants in our study. It is generally believed that ethylene blocking is extended when a series of sprays of STS is used compared with a single spray of STS (Reid et al., 1980).
It may be possible to induce male flowers on genetically female hemp using other ethylene perception inhibiting chemicals such as 1- methylcyclopropene.
Conclusion
This study demonstrates that male flowers can be produced easily and consistently on female plants through application of foliar sprays of STS under short-day conditions.
Overall, STS at 3 mM was the most effective treatment for producing the greatest number of male flowers on female hemp plants.
we did not observe any plant phytotoxicity or delay in flower development.
Furthermore, we were able to achieve 95% to 100% conversion to male flowers for all hemp strains.

I'm floored by the amount of knowledge you are sharing. I am learning so much. Thank you!
You are welcome, be sure to share the channel with others!
You are great, man! Have watched a bunch of your videos and I love how much science you bring into them. I wish this stuff was available 30 years ago lol.
At least you are here now;-)
1) the video we’ve been waiting for!
2) the closed captions finally got your name right at the beginning!
3) the intro slaps
1.) Always glad to produce content you are looking for!
2.) Closed captions are not perfect, but can be a good tool for some to utilize.
3.) Great to know the DeBacco University intro "slaps"!
I literally just asked this question on one of your videos, and the next one to pop up answered my question.
Love your videos man, super informative.
Many videos on the channel so keep searching on topics you want to learn more about;-)
These mini lectures are great. Really appreciated!
You are welcome.
Thank you for the video! I almost didn't watch it because I've done so much research on this but once again you taught me things I didn't know. Thank you for all the time and effort you put into the videos for us.
Great to know the time and effort is appreciated and also happy to provide new information on a topic you may already be well educated on.
@@DeBaccoUniversity There is not a single seed bank in the world the claims their Feminised seeds are guaranteed 100% Female.

the more geeky the looks the better the info! exception made for dr bugbee. Thank you alot, great video left nothing to doubt :)
Do not necessarily judge a book by its cover;-)
I was able to produce feminized seeds by stressing a female plant starting around 2-3 weeks into flowering. I let her pot dry out a few times,did some pretty extreme temperature swings,and then lowered the light until I caused some minor light burn. She threw out some pollen sacks and I got some female seeds out of a couple healthy females I used the pollen on. So far my results have all been females,about 50-60 seeds in. Not as scientific,but it worked😅 Great video!
Glad it worked for you, but this would not be a reliable technique to depend on and there is also the plant stress to consider.
Me too All I did was switch the light cycle 3 times.
Would the seeds that come from a purposely stressed hermie female produce hermie prone seeds?
@@KushByTheBush From what I've been reading, the seeds produced from the plant will only contain fem dna because the mom (regardless of being hermied) is still fem.
@@KushByTheBush Yes if the new plants are stressed in the same ways they are likely to herm' but if you don't stress them you can get some amazing bud' I've done this myself and as long as I don't stress them they stay female.
how does this not have MORE LIKES?! i have not seen very many, if not any feminized seed information on RUclips that mentions the silver method.
also your explanation of the genetic factors, is so well done, clearly excecated and easy to understand!
thank you very much for this information! 😍💚
i think the method you've shown here is FAR superior to what ive been doing for my whole life,
both in its simplicity\easiness to follow, and the fact that it is reliable and measurable unlike the way i've been doin it!, thank you so much for bringing up up-to-date!! XD
[warning: THE FOLLOWING SHOULD ONLY BE ATTEMPTED OR CONDUCTED BY A PROFESSIONALLY MINDED ADULT, IN A SAFE CLEAN ENVIROMENT, USING THE PROPER PPE AND PROCEDURES]
i always used colloidal silver (sp?) which i was taught to make by an older grower, by making an anode and cathode out of pure silver solder wire, and attaching each end of it to a small voltage\ milliamp DC wall transformer (plugged into a GFI\fused power source for safety)
then i would put those two thin rods into a glass or jar of distilled water, and leave it on overnight, and after a while you could actually see the silver forming strange tiny dots and orbs FLOATING in the water itself! like it somehow stayed in solution ionically or something?
anyway this stuff was really dangerous to get on bare skin, so if anyone follows the above directions be very careful and use proper protective gear\gloves\mask\goggles\lab coat etc.
a small ratio of this to regular watering\feeding times would quite quickly force my females to produce male flowers as well. (or males to produce female flowers also, making male-inized seeds)
once done, the plant is cooked however, like i had to baby it along to completion (maybe i was using too concentrated of silver-water, oops!!) been a very long time since i used that method.
i will definitely be giving this method a try next time i go for a batch of fem seeds!

That was a great explanation of the process, there is a lot of confusion out there on how to properly do this. Cheers 🇨🇦
This was part of the reason for this and many of the other videos here on DeBacco University to provide straight forward scientifically supported information.
@@DeBaccoUniversity THANK GOD someone is actually teaching the REAL SCIENCE. Perhaps some of these pot seed companies will FINALLY understand they need to TEST GROW and ESP on f2 generation. Thats where the irregularities start to show. You will be FINE 1st set of seeds, but when you start to cross THOSE SEEDS with another new strain you get 1 out of 4 unstable recessive traits
Thanks Prof ! Good insights !

I’m glad I ran into this vid because I just had a plant herm so I decided to collect the sacks & put them outside to burst. Thank you!
Sounds like it was perfect timing for you!
Remember if a plant has herm tendencies you'll transfer that to the seeds. I also hope you dont have a close neighbour with flowers too!
@@dana102083 That’s fine with me. I do it indoors so it’ll be more for experimental use

Thank you!! :)
You are welcome!
This video has given me direction!!!! Many Thanks. I havre a couple questions about precursors. Is there any danger of the final molar concentration being compromised if i use commercially available distilled water? I am concerned in the accuracy of my final molar conc. In addition, most of the readily available Silver Nitrate is 99% plus in purity. can that 1% have the potential to adversely effect my final molar concentration? Do the silver nitrate and the sodium thiosulphate bond or do they simply dissolve and remain suspended in solution?
Glad to provide direction, in short the use of distilled water as you mention would be advised to help ensure accurate concentrations.
I've used colloidal silver with perfect results. Seems like a cheaper more simple method to me.
Thanks for sharing!
GA3 Gyberillic acid. Will make the pollen sack stretch into a long branch. Making it easier to spread the pollen.
Be cautious with any hormone applications.
hi great vid. I have a related ? I grew 12 plants last year in 2 rows of six and staggered plants in one row between those of the other. 4 feet apart When I harvested them all plants in the back row next to my neighbors cyclone fence ,all showed seeds while those in the second row didn't. I can't explain why any got pollinated since no one around me is growing and if some I dont know did grow and they let males release pollen I'd expect both rows to have seeds..thx
Sounds like close proximity pollen, did some one remove a male plants and drag it on the outer row?
thanks DeBacco
You are welcome Pangaea.
This is great, and thank you! I love the info, but the typos on the chemical preparation page bother me a little bit, although if people follow it as written they'll get the right result and they'll never think about stoichiometry. Ignoring the hydration - since you got the pentahydrate part right - sodium thiosulfate is Na2S2O3, not NaS2O3. Silver thiosulfate is Ag2S2O3, not Ag(S2O3)2. Also, they mentioned how methylcyclopropene might work, and if people don't know, that's the gas that they use in the supermarket to keep bananas from ripening.
So I was kinda wrong here. The sodium thiosulfate was wrong, but the "silver thiosulfate" was close to right in the video although it's more complex than that. It's not Ag(S2O3)2, but the [Ag(S2O3)2]-3 anion, so the chemical species would be more like trisodium silver dithiosulfate, although the silver dithiosulate is just the predominant ion in solution, and other complexes are present as well as sodium nitrate.
As always see the description for a link to the works cited.
@@DeBaccoUniversity I feel kinda dumb for typing that now, but on the other hand I'm glad I did since it made me look into it deeper. Thanks for the works cited!
How long should I be spraying the plants? Should I stop sprting the STS once I see male flowers staring to become visible, or should I continue to spray the silver?
6:27 has your answer at the bottom of the slide, two applications as 3rd and 5th leaf stage.
When producing seeds this way are the genetics going to be the same as the plant that produced the pollen? As I have one panama red plant left and it’s genetics are not the best, but would love to produce more seeds from her to cross with another mother plant I have.
End result of a pollination is a mix of the two plants in the cross.
In my first grow during flowering stage, one of my four plants got heat stressed and turned hermaphrodite. It pollinated the other 3 plants. The seeds I got from those plants usually end up giving me about 95% female plants
Interesting but not likely repeatable.
Once a female is reversed with sts to produce male pollen sacs. What type of nutrients should the plant receive to help mature the pollen? Bloom nutrients?
General grow nutrient formulations should work just fine as pollen production does not require the grower to push a certain nutrient.
Does anyone have an input on the PPM (parts per million) of Colloidal silver?? I've heard 80 PPM minimum to get the job done???
Calculations provided at the end of the video.
I also realized when I let the male grow it starts to produce buds and polinats itself
This can happen but watch your other female plants.
Question: What is the difference between STS and colloidal silver? Which one would you recommend if they are different? Thank you for your great content! Cheers
Colloidal silver is only silver (Ag) and STS is Sodium Silver Thiosulfate so not pure silver, but this is the product that is advised in the study to create feminized seeds.
@@DeBaccoUniversity Many thanks!
@@DeBaccoUniversity Would colloidal silver work as well, using this protocol? Thanks.
@@steveandrews8301 did it work?😉👍
@@peterdeans4635 No, it didn't work. It seemed to chemically burn the plant a bit, so I stopped. It was from homemade Colloidal Silver I'd made, so I'm not exactly sure how strong (PPM) it was, either, so that could have been part of the problem, too. I had made it double strong, maybe too strong, perhaps? ...
Does shaking the c. silver treated pollen sacks onto another female plant render said female buds unsafe to vape?"
Since this would likely go through an extraction process... no.
I have a couple questions. In the video, you used rooted cuttings; in the case of using plants started from seed, when would you begin the STS treatment?
Assuming that you have several other of the same feminized plants growing next to the plant that is treated, should the also be sprayed or would the pollen from the treated plant be enough to fertilize them, too? Would it be more effective to collect the pollen and use a Q-tip to pollinate the other plants, rather than treat them?
You say that you did three applications 7 days apart, with the first on April 30, but you say you did the second application on May 14? Wouldn't that have been the third application, with the second being on May 7?
You say that you switched to the 8 hour light cycle on April 30 and on May 14; if you began on April 30, how. could you begin again on May 14? Was there more than one set of test plants?
I have seen some videos that recommend only spraying part of the plant, perhaps a few leaves or one branch. Any thoughts on this?
Are there some varieties that do better than others with feminzation? Indica versus sativa?
thanks
Answers to all your questions...
1. Plants were ≈6 inches high with two shoots when foliar sprays of STS were initiated
2. If other plants are female, no pollen would be produced if untreated.
3. Treatment is needed to generate the pollen.
4. Plants were sprayed to runoff (about 20 mL/plant) on three occasions, 7 d apart, beginning on 30 Apr. 2018 for the first replication and on 14 May 2018 for the second replication of this study.
5. On 30 Apr. and 14 May, plants began receiving short-day conditions of ≈8 h using a blackout curtain to initiate the flowering stage.
6. Full plant sprays in this study.
7. Should not be a difference.
@@DeBaccoUniversity Thank you.
A plant grown from seed may be taller than 6 inches before it produces sex organs; do you treat plants grown from seed as soon as they display female sex characteristics, or do you allow them to grow buds before treating them?
What i was trying to ask for #2 was if the amount of pollen produced by one treated female would act to fertilize surrounding females enough to produce a large quantity of seeds, or would it be better to use the pollen from the one treated female to hand pollenate the other females?
I don't understand your answer for #5; if you begin the blackout curtain on April 30, how can you begin it again on May 14 unless you stop sometime in between?
@@nuclearstarr he did the experiment twice. First one started April 30, 2nd one May 14.
Debacco.... read everything again..
Thanks for the video sir, can you provide the reference of your calculation for preperation of 3mM Silver thiosulphate...it will be very useful for me...thanks.
Check the end of the video and also link in the description for sources.
I got you with the calculation for .01M Ag2S2O3 solution(more is better; 3 mM is 0.003M), With straight sodium thiosulfate tho not the watered down pentahydrate.
Na2S2O3 + 2 AgNO3 -> Ag2S2O3 + 2 NaNO3
To make 1 liter(0.01M… mol/liter =molarity):
0.01 mol Ag2S2O3 x 1mol Na2S2O3/1mol Ag2S2O3 x 158.1g Na2S2O3/1 mol Na2S2O3
= 1.581 g sodium thiosulfate needed and for silver nitrate
0.01 mol Ag2S2O3 x 2 mol AgNO3/1 mol Ag2S2O3 x 169.88g AgNO3/1 mol AgNO3 = 3.4g silver nitrate needed
Question. If we apply this method to cuttings from the same mother will the seeds essentially produce the genetically identical plants to the cutting? When breeding I believe the offspring will be a random 50/50 mix from both parents but if both parents have an identical genetic code….my thinking is when you find a good keeper I’m always worried there’s going to be a disaster at some point in the future and I’m going to lose her…would be great to have a jar of seeds that I know will grow the same plant at a later date. Thanks
Genetically similar plants as there will be some slight mixing of genes, think of it like a calico cat.
The original article suggests spraying to saturation. (approx 20ml/plant). thoughts?
That may be a good starting point, the key is the concentration to apply. You can spray until runoff.
@@DeBaccoUniversity Tks for a really quick response. I will be doing my first application tonight. I’ll keep you posted!
@@mitchellchristophersen175how did it go, did it work?
Why is it that some genetics are harder to flip than others? Any specific chemicals?
Some that have some Ruderalis in their background can be harder to flip. Others just have a slower change and is not characteristic of any specific chemical end products produced by the plant.
Is the solution dangerous if it goes on the clothes or u touch plants next days of spraying ?
With any spray product keep it applied only where intended.
Hello, when you use this chemical method on an auto flower female will the seeds be auto flower?
Odds are very likely.
Hi, I'm a bit confused because in the dosage table you mention Na2S2O3 x 5H2O, but the picture on the right shows Na2S2O3. Is there a difference in which one is used? Cheers
See time stamp 6:25 for full instructions.
@@DeBaccoUniversity okey now I understand Na2S2O3 Pentahydrate is Na2S2O3 x 5H2O. So for this recipe, you need to use Na2S2O3 x 5H2O not Na2S2O3 - both are sodium thiosulfate but have slightly different chemical formulas, so they have probably different dosages. Thanks, cheers
I have another question for you. Once a female clone is reversed with sts and produces pollen. Can that pollen be used to breed with other female clones of other strains to produce feminized seeds of different strains? Is this process ok? Or should breeding be done with a real male and female plant then reversed to produce feminized seeds?
Basically, yes as the feminized pollen only has the X chromosome so pollinating other female flowers will result in feminized seeds.
Thank you for the reply.
Excellent. How long do you veg the plant out before you spray and flip to flower?
See link in description for the articles details, but in short... "Plants were ≈6 inches high with two shoots when foliar sprays of STS were initiated."
Colloidal silver, a week before flower spray once a day, spray again for another week daily but I suggest isolating an area as to not overdo it-that of which can be done. Hard to find sometimes, usually found in an organic and all-natural shop. Enjoy that and grow on
Thanks for sharing.
Stoner moment need some help.
By spraying the STS , This is causing it to stress the female to make male parts to pollenate. Herself- For feminized seeds? And these said seeds will be all female?
Or is it that you catch the pollen that is produced, and hit other females plants with it. In turn making all those seeds female in future runs?
Any help is appreciated. :)
It induces female flower formation on the area it is applied to.
Is there an alternative to silver? I.e. iron or copper?
Silver is the only option if you want these effects.
Are you saying that they flipped the plants to flower as soon as they applied the first application of the sts?
You are correct as stated in the study.
@@DeBaccoUniversity
I se
What happens with the ppl who keep crossing hybrids? Remember what happened with Mendell's hyybrid pea experiment. Every 4th seed reverted to recessive traits.
Potential accumulation of recessive genes depending on the crosses being made.
sometimes you find diamonds in those recessive ones
@@Alfred_the_IV NO! You get NOTHING like either parent, and its NOT stable, reliable, or reproducable. AG dept REGULATES veggie seeds to PREVENT this phenomenon, and they need to regulate pot seeds! I WANT RELIABLE SEEDS.....NOT FROM SOME IDIOT who thinks your gonna find a diamond in a "RECESSIVE" gene. That theory LACKS ANY SCIENTIFIC FACTS~ or REALITY!
Thanks for the video, great info. ,I know this mixture shows it being mixed together but can we keep them seperat and will it last longer that way? Also Let me make sure i understand this right, after mixing the first batch we should have a liter of each 1 sodium thiosulphate and 1 silver nitrate if we did not mixe together or a 2 liter if we did mixed together , then to dilute it to 3mM we mix each one 1:1 so each liter with another liter of disitlled water and we should have 2 liters of each kind or if already combined a mixure together of 4 liters, is that correct? thanks for the info
If you want longer term storage keep them separate in original containers. One note on the steps you outlines, the mixing needs to occur in a special way (what is added to what), so be sure to read this over as well.
@@DeBaccoUniversity thank you, yes I saw that one needs to be added to the other, does my math look right? I wasn’t sure if I understood the mixing ratios, love the videos lots of good info
this raises a bunch of question for me
1 is the genetics of an auto fertilized plant identical to the parent seems it would be since there is no outside genetics being introduced.
2 is the best way to make hybrid strains with forced male flowers on a female plant then fertilizing another female of different genetics ?
3 if i make a hybrid plant with 2 different parents is there variations in the plants grown from the seed created? my feeling is there will be some variation. you would the need to grow a bunch of plants from your hybrid pick one you like then force male flowers to create a stable hybrid.
watched some of your other vids . .deep subject
1. What do you mean by auto fertilized? (Fertilized with a Ruderalis or self fertilized?)
2. Take two different stable genetic lines (that have ideally been selfed for 7 generations) and then cross them
3. F1 generation will be the most stable, but taking seeds from these plants you can expect varied results
@@DeBaccoUniversity
1 sry i meant flowered nor fertilized
2 is it better to use pollen for making a hybrid from a true male or a female that has been forced to male. i think its the former.
to establish a stable line you breed the plant with itself for 7 generations?
does that mean male/ female or forced male flowers on a female?
there is variation in genetics in seeds produced by forcing male flowers on female plants and fertilizing that plant?
thanks for your reply and all your vids
its a fascinating subject
Does this work on auto flower
In short... yes.
@@DeBaccoUniversity Except that you wouldn't have to provide "short days" for the autoflowers, in this case - correct?
I will say this, this stuff makes the plant flower two to three times better! I sprayed every day for 3 weeks. Control plant is same height, but not even close on flowers. Sooooooo
Thanks for sharing!
So if im polinating autoflower plant, the seed will be autoflower feminized seed?
... ideally;-)
I know this is older but I have a question. Can you make feminized seeds from a plant that was created from a feminized seed?
In short... yes.
Nobody talks about the safety of this chemical is it safe to use indoors what are the risks
Look up the SDS sheets for any chemical online.
Question- if 1 or 2% of the feminized XX seeds end up being male plants, are they really just hermaphrodites showing more male characteristics or more male flower. So if that's the case, these hermaphrodite plants would be producing XX pollin, and it may be beneficial to keep these herms. For future fertilization for XX seeds??? Mathematically these herms wouldn't ever have xy???
In the best case scenario plants would still set seeds which will reduce cannabinoids and also "ruin" the visual aspect of the flower and increase labor to clear out the seeds. So, this is part of the reason why all pollen producing plants should be removed.
I would like to try this method on cannabis with 33% THC. Any one try on that type of plant? The formula makes a huge amount. What percentage Silver Nitrate?
The end of the video provides you with the specific details you are seeking.
@@DeBaccoUniversity I do not understand the math when my Silver Nitrate is "0.1 aqueous solution" and the 2.04 grams of a solution (ml). Please forgive my inability to do math...How many ml of the Silver Nitrate?
@@SpruceSculptures its such a small amount it seems weight is the only accurate measurement, just like baking. Id suggest if serious to make this buy a decent scale for 15 bucks. We made colloidal silver using batteries and bought silver sticks. Seems a bit easier. Less math.
@@dana102083 I got a pharmacist to assist me. Plant has had 3 weekly treatments with no effect at this point. Going to increase frequency of spraying as it is making female flowers.
@@SpruceSculptures 120 ml Of 0.1N aqueous silver nitrate
I always Rodelize...
You can end up with hermaphrodite cannabis plants. Moreover, the pollen produced in the pollen sacs of hermaphrodite plants are not as potent as the pollen produces by male cannabis plants. www.getispire.com/what-is-rodelization/
Open Question(s):
Any thoughts on treating a female born from feminized seed? Will the pollen be viable?
Will the resulting generation be perfected or retarded in some way?
Thank you for your time and consideration.
Not sure of the question... a female plant will produce female flowers which are receptive to pollen, not producers of pollen.
@@DeBaccoUniversity Sorry, Dr. DeBacco.
If a plant grown from 'feminized' seed is treated with the silver solution, will the pollen that results from this treatment be 'normal' in comparison to the pollen created by treating a female born of 'regular' seed with the same silver solution?
In essence, does a 'feminized' seed contain any genetic coding besides what is contained in a 'regular' seed? If different, are the differences detrimental to 'normal' expression?
I suppose, that was my loooong-winded way of asking if it is safe to treat a female plant born of feminized seed, to reproduce its particular phenotype [if selfed] and/or pass on its own traits [if crossed]?
Thank you for your patience.
@@DeBaccoUniversity I’m curious about @Geronimo’s Bones question as well. It’s hard to get a straight answer to this question.
@@tyrannosapienlex A female plant is a female plant. However, the one from a regular pack, you will have different phenotypes/expressions of both parents to choose from (S1 from "Regular" seeds). On the other hand an S1, is from that feminised seed you choose and most of your seeds should be close to identical with the exceptions or runtz or weird ones that should be minimal. Less rececitive traits.
@@telnek Merci, Michel! Your explanation makes good sense to me. Very good!
This did not work for me. I tried two different cycles. If anything there were more female flowers. First round was done the way stated. Second round I sprayed the plant (drenched) daily. NO difference. Sorry to report this as I really wanted to get this plant to herm out.
Concentration and timing are key for success.
@@DeBaccoUniversity If concentration was wrong it was due to provided info. Like I said I tried it exactly the way described the first time, just altered how often the next. It did not work
1st application 5 days prior to flower then once every 5 days til u see balls, may need to increase coincentration if superhard to flip but thts not a bad ting since it means ur workbg with a stable female.. hope you cloned... try again .. i use 1g silver 5 g sodium thio, each in 500 ml, then mix 50 of each +900ml of distilled water for a 1:9 sts to ho solution for final spray. reduce to 1;6 if still no results bnut usually soraying 1 time 5 days before flip to flower and then continuing works best
@@SpruceSculptures what strain you used ?
Can I send u some seeds for u to do it for me
In short... no;-)
