No Shane , No gain! I'm absorbing as much of ur lighting knowledge as possible...thank you for making the info digestible, and for demystifying the light game for a relative newbie like myself!
billy bobbert not true. "Two plant scientists by the names of Dr. McCree and Dr. Inada performed several studies in the 1970s to determine the influence of light spectra on photosynthesis. This research resulted in the creation of a photosynthetic response curve that is now appropriately known as the McCree curve. If you refer to the McCree curve ( Figure 2 ), you will notice that red light (600-700 nm) is almost twice as effective as blue light (400-500 nm) at driving photosynthesis, with green (500-600 nm) light in between the two. Prior to this research, it was a common misconception that since chlorophyll absorbs light mainly in the red and blue parts of the visible light spectrum (leading to the green color of plant leaves) that green light was not used by plants for photosynthesis. However, precise and independent measurements of photosynthetic activity under different wavelengths by McCree and Inada demonstrated that light in the green spectrum (500 - 600 nm) is nearly as effective as blue light for a considerable number of plant species. The short explanation for this experimental fact is that higher plants have evolved both biochemical and biophysical solutions (e.g. accessory pigments) to utilize green light. These accessory pigments (mainly carotenoids) can be thought of as storage molecules for photons that are not directly absorbed by chlorophyll."
Thank for that. I am new to artificial plant lighting and I know nothing. I do have a couple of bonsais ( Ficus Retusa) which struggle through the winter months and I have been trying to get good advice on a good option for a couple of them for the winter months here in Yorkshire. This possible is the one I am looking for as the overhead gantry of lights gives a nice mobile use and ease of use for my home use. Any advice would be great. Tim Marshall
The results should be enhanced with some Mylar walls around the plants. Do you think it would be good for seedling in cups with that sort of little Mylar enclosure or some reflective sheets?
If the manufacturer does not recommend then adjsut the light so the centre point measurement is about 1,200 umols/m2/sec PPFD. If you measure the coverage area until the readings become zero it means you are capturing all of the light emmitted. Hang it at the optimum height and then create a grid under the light that extends beyond the light spread. If the light is spread very wide maybe use reflective walls and measure within them. I have an excel spreasheet for entering the data and creating a PAR intensity map. Email me if you want a copy shane@partechled.com
Hi. Do you get many questions about growing carnivorous plants under such lights? In my small experience with IKEA LEDs when the plants are directly under the hot spot they colour red very quickly. Most but not all carnivorous plants require full sun. I have a Heliamphora which is considered a full sun plant. Using your android phone hack I have estimated the PPFD at over 400 directly under the bulb. I have seen on your videos of PPFDs of 1200 being maximal? I also put a small Nepenthes under similar light and it went red very quickly. Nepenthes are considered moderate light plants. They are equatorial plants but are shaded by other plants in their natural habitats. Any help or comments would be appreciated. Slainte Adam.
Hi, IKEA has on their Danish website written that this light give out approx 100 umol/(s*m2) PPFD, but you seem to measure 20.7 umol/(s*m2), is that correctly seen? If yes, what do you make of that large difference ?
They publish their PPFD figures so you can compare directly. The MIGRO outputs an average of 211/ 0.36m2 = 586 average PPFD on a 60cm x 60cm grow area. The optic 1 XL delivers 540ppfd averaged over a 60cm x 60cm area.its similarly priced and a nicely made unit so you have a difficult choice 😉
thank you, thanks to you I just bought 3 supports with leds and if you watch the videos on my channel it works very hard I am very happy with the result! awesome thanks to you.
Shows that some of the energy is being wasted on making light plants don't use at least. Still for how cheap it is, I may get one and make a nice looking hydroponic setup with stained wood or something as a gift. This could easily grow lettuce.
30-35 inches tall in a 60Lx60Wx160H cm grow room , just wondering in your opinion will the Mars hydro 240 do the job from seedling to harvest or would i need a better led? Thanks again
+Hidden Harvest Grow Lights Stop trying to sell your lamps on a migro video. That's not nice, make your own video and try to sell it there. Show some self respect and respect to the creator of this video.
Thank you for the review and for all your other useful videos. You really help to cut through the obfuscation in the grow light industry. I'm looking for a compact, relatively low wattage LED to grow some basil and parsley through the darker months. I've already got two 24W T5 propagation lights but would be happy to cut down on the electricity use a bit more. This IKEA light seems like it would do quite well, though like you say it is a little pricey for what you get. Have you any opinion on the Secret Jardin 26W TLED? It's similar in price to the IKEA light and the numbers on their website ( www.secretjardin.com/spectrum-and-p-a-r.php ) suggest a PPFD of 51 when used in combination with a grow tent.

i guess it is kinda randomly asking but does anyone know a good place to watch new movies online?
I used these for my pepper seedlings this year. Did very well.
CORRECTION at 5 mins: The spectrum ouput % is 12% Blue, 44% Green and 44% red.
You dont have a way to show us the spectral graph or do you?

It should have more blue in it considering it’s being used for propagation/seed starting

Hi Shane, loving the honesty as always. More than interested with the results that little VAX gives you
The results should be enhanced with some Mylar walls around the plants. Do you think it would be good for seedling in cups with that sort of little Mylar enclosure or some reflective sheets?
I was wondering if you did a test on these, as I have two of the large ones, and one of the smaller ones. Thank you!!!
Nice. I got a few new lights I want to measure and compare, going to use your method of calculating the average and the efficiency.
But how would you compare efficiency of different lights that have different coverage footprints? And how do you decide what height to set them at?
If the manufacturer does not recommend then adjsut the light so the centre point measurement is about 1,200 umols/m2/sec PPFD. If you measure the coverage area until the readings become zero it means you are capturing all of the light emmitted. Hang it at the optimum height and then create a grid under the light that extends beyond the light spread. If the light is spread very wide maybe use reflective walls and measure within them.

Hi Shane my fellow Irishman .love the videos and learning lot about grow lights from yourself keep up the good work
Thanks Alan. Why don't you drop in and see us? Are you near? We are in Cabra

Great video Shane keep them coming!
When you say Par and power it sounds exactly the same
Very nice light I love to have it in my garden ✌️💚
Hi Shane, do you know if these give off any UV light?
Is PAR cumulative? Would I get 300 PAR in the center if I put 3 of these next to each other?
Cheers thats not bad light at for the coverage and wattage its good

oh, i see that they also write that the spectrum used is from 180-800 nm, instead of the typical 400-700 nm... perhaps that is the difference?
Review the HLG quantum boards
Hello, we have reviewed one already, just chekout the RUclips channel
MIGRO i seen it and love your videos by the way. Im interested in the 288 or 304 reviews.
What do you think about the SPYDRx plus ?
Cannabis Grow videos fantastic light
Sorry i can't find the lamp on the link, can you help me?
Can you do a review on the optic 1 XL? I can't decide between migro 100 and the XL... thanks

thanks.
They need to make a file similar to IES that helps people model these lights
Interesting unit!
Hidden Harvest Grow Lights ::: Wonder what the price is, most of us would need quite a few!

Thanks, can u post a link?

@@FinehomesofNewHampshire Link me your lights. Cant see them nowhere
thank you, thanks to you I just bought 3 supports with leds and if you watch the videos on my channel it works very hard I am very happy with the result! awesome thanks to you.
do you need an airstone for this system?
Im assuming you are using this light for aquarium plants. You do not need airstone for aquatic plants
Great job, the mini grow lighs are importante to,not everi One have gigante grow Room
To be hounest. I actually think that PPFD is not good at all, but ok, there must be a lot of worse crap on the market then...
at 5:00 12+34+34=80%. Where is the missing 20%?
Non-photosynthetic active radiation. That's my guess.
Nice try, but I don't think so. Non-photosynthetic active radiation doesn't count. The total should be 100, like everywhere else. Shane?
The spectrometer measures spectrum dude, not par.
The spectrometer measures spectrum, but we count photosynthetic active radiation only, dude. But yes, probably that was the problem

Hey shane, check out my optic 1xl grow so
can anyone help to buy one pcs in your location? send to me 1 pcs, located in china mainland.
Mars hydro 240 or Viparspectra 300 which one, first grow
420Sheff Neither. Mars if you have to. Run long for flowering. 😉
Thanks appreciate the reply , is they any led you would recommend not too pricey but will do the job for two plants cheers
420Sheff ruclips.net/video/IWIt_gD6K9w/видео.html
Mine. 36 watts. $79 + shipping
How big are you growing the 2 plants?

how can we get them but much stronger ?
ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/#
GingerRuss75 Thanks ! I'll check to get those Samsung led lights by IKEA.
those are not by Ikea, but they are stronger (1000w equivalence i think) , plus you have to DiY the bits.
Don't drink before you do these.
