- In this video, I show you how to revive old seeds (in this case, Peruvian Torch cactus seeds) using hydrogen peroxide and sugar.

If you are interested in buying pure, well identified San Pedro seeds and seedlings, as well as San Pedro relatives, please email me at: sanpedromastery@protonmail.com
If you have a question, I will only reply to questions about cultivation. Please no questions about the psychedelic properties of these cacti.
I tired this method for some very old rare seeds that would not germinate. After this process, 5 out of 12 germinated and are growing well. I will be doing this method on any rare or old seeds in the future. Only the sinkers germinated, none of the floaters did. Thank you for the videos.
Nice one Jerry. I will adapt this method to a couple containers that did not grow, or only a few seedlings grew from but have some really rare and cool varieties in them.
An increase of 3% to 50%? Wow that's impressive Jerry. Thanks for the tip!
I like to soak seeds in a clean cafetiere using the plunger to keep them submerged...non viable seeds should still float when the plunger is removed...this speeds up the water penetration as there is an element of pressure involved...similar to swimming in water; the deeper you go, the more the pressure increases.
Excellent video! Thank you so much for all of your effort and information on growing these precious, sacred cacti. Have you ever done any grafting? I hear that grafting can speed up the growth of slower cacti. Maybe it would make a great future video.
I have not done any grafting ever, but may try soon for the purpose of a video. A viewer from Torino, Italy has forwarded me detailed instructions for grafting, that I will follow.
Gives me hope for some loph seeds that were given to me a few years ago. Just not been in a proper place to start them but now have a greenhouse and will wait till it warms up here in Texas.
Coconut water powder, aloe powder, and humic acid are all worth investigating for helping germinate old seeds
Thank you for this very informative video. I will try this on my tropical pitcher plant seeds, which often quickly lose viability.
peroxide for the win!
Thanks
I may end up having to try this. Almost every time I try to buy wildflower seed, I end up getting nothing.
Hi there. I recently just bought a pachanoi but want to repot it into some different soil. can you please do a video on that?
Okay, sure, I will do a video on repotting a San Pedro very soon. In the meantime, there is one of my videos about the right soil mix for San Pedro, and another one about fertilizers for the San Pedro. These might be helpful to you too. :)
@@sanpedromastery6262 thank you!
Ive had some seeds from a seller in bolivia for close to 2and a half years and left them in the bag and in a dark cool space since i bought them would this be needed for them to grow?
If they were fresh at the time, this probably won't be needed as they would have only lost a bit of viability. However, if they were not fresh at the time, or if you don't know, it would be a good idea to revive them. If unsure, you can do a try on a small batch.
I cheated. I blew the float ones push down into the water. If they go up'n down constantly in the water, what does it mean?
Seaweed is better than sugar. Seaweed also contains a small amount of sugar.
How do you store your seeds?
Great stuff! Wondering if 2% bleach solution for 20 minutes would gently dissolve outer seed coating AND disinfect. Haven't tried either yet.
If you try this, please let us know the results! Thanks :)
@@sanpedromastery6262 I'll try both on split groups of old seeds I have and share results. Hoping for a lot of tiny green things poking up within ten days.
@@cactusislandnurseryflorida Thanks, keep us updated!
@@sanpedromastery6262 Finally did a split planting today with Pilosocereus Roseana and P. Royenii, using your method and the unscented household bleach 2%/20min. I put paper towel over hydrophobic floating seeds to inundate them 360 degrees with etchant and sugar water. Usually takes me eight days to see green. Royenii is a notoriously tough one to germinate from purchased packets and I have high hopes that they'll pop.
@@cactusislandnurseryflorida Fingers crossed! Hopefully that will work for you. Keep us updated.
I understand the hydrogen peroxide is for fungus removal but does anyone know what the sugars purpose is for? I've seen this technique for many seeds before and just wonder about what mechanism it accomplishes in the seeds.
Unrelated to this, also wondering if its possible to have seeds germinate in mostly cactus soil without any perlite. Would adding perlite to the top of the soil help germination or would it be best to not add perlite after spreading the seeds on the soil surface?
I don't think the hydrogen peroxide would be any good for fungus removal here as it is way too diluted. Hydrogen peroxide should be used much more concentrated (if not neat) for fungus removal. I think the way it acts here is by breaking down the seed coat and therefore allowing for the seed to take in more oxygen.
I think the sugar nourishes the seeds. If I am wrong on this, please someone correct me.
Sure, you can germinate them without the perlite, though for better results it's better to have 50% or less organic material. Perlite has to be mixed with the soil, I don't think adding it on the surface would be of much help. More of an annoyance in fact, as it floats with water and sticks to the plants...
@@sanpedromastery6262 thank you for this information. Very useful!
San Pedro Mastery anything over 3% hydrogen peroxide is very efficient at destroying organic matter, it destroys viruses, bacteria, and mold spores. Since this is much less than 3%, it probably won’t help kill any mold spores. Hydrogen peroxide cannot be used neat (undiluted) because it forms violently explosive peroxides, and is commonly used as a rocket propellant.
Older seeds use up their natural sugars that help the embryos survive. If embryos have any life left, the added sugar can give them a slight boost for germination.
Can use honey instead of sugar?
Hi Anton, lm going to put some honey in my seeds as lve seen honey doing wonderful things. Fingers crossed for this coming summer.
I have 15k tricho seeds dating for mid 2017 and late 2018...so I still have a chance?
cactus seeds are extremely viable , like come on you bio class failure , they are freaking cactus
Juliano C. Yes
@@playerunknown3234 some yes, are extremely viable, other not. :p I got some 2 years old seeds and the germ was about 3%, while in those fresh I've got 99% :p
@@playerunknown3234 so, is all about the adaptation and lifecycle of the plant...may I'm not the failure here... But ok, edgy dude of the websphere :p
@@dg5450 I gonna try them, yet all the people who got sucess with old seeds had stored them in paper bags...mine are at the plastic bags from the seller. In the only bag I tried - Pumayacan, from C.H. - got 0% (3.5 years old) :p
Why don't you use GA3 ?
I don't really know if you're still going to respond but will this method also work for other varieties of cactus seeds and succulent seeds?😅
Yes,it has worked for me anyway.
I am trying to germinate 6 year old vegetable seeds. Any comments or suggestions?
"FRAGRANCE OF SOUND" ® ..yes I do , "throw them out and buy some new ones " ...well,there it is ,that's my advice
@@danfield6030 I got a lot of germination by soaking them in hydrogen peroxide 20 to 1 and sprouting them. Have a lot of plants growing now. So no, don't throw them out. I saved a lot of money sprouting these seeds
trichocereus seeds?
i wish there is way t know from seeds. cuz im iran i cant buy seed from out of here of if i coul it would be so expensive. could you at least tell us how to identify them from seedling
I don't think you can tell from looking at them if seeds are old or not. As for identifying san pedro from seedlings, that is impossible to do with certainty.
How old is old seeds please
Difficult to say... 5 to 10 years or more... Depends on how the seeds were stored.
Aha, that's why only 40% of my peyote seeds germinated.
Is it possible to buy seeds from you? :)
It looks like he sells them on Open Bazaar. Check our his “where to buy seeds” video.
