Can you list these companies for me please? We need alot of lights and the more I read the more confusing it isSwaying customers to purchase what's in the sellers best interest, not the buyer
Not right now & i don't know all there names.Can you list these companies for me please? We need alot of lights and the more I read the more confusing it is
Can you name some of the companies that are not swaying customers to make the wrong choice?Not right now & i don't know all there names.

In the video Bugbee showed green can also penetrate a leaf fully just like FR, but you're right it doesn't compare to FR. So many outdoor plants have this healthy natural green leaf color and bushy great form - in an indoor scenario many leaves would turn yellow if a plant had such a structure.your chart show a similar result would say, 550 is abit less absorbed then blue n red f.e., even less absorbed is 730 and further up.
The UVA may be absorbed also in the middle of the leave because of this. Maybe one of the reasons why UVA hasn't the same destructive potential than UVB or UVC. If the radiation is high in energy + gets absorbed at the instant it comes into contact with matter the result is great heat. But the energy from UVA gets distributed over a greater volume than blue light.interesting to see in your chart how well uva is absorbed,
would had thought its less, while i can also clearly see that all my 390-400 is absorbed well.
tyvm, unfortunately I got a thripse problem but apart from that, yes they're lighthungry and growing rapidly. gonna transplant tomorrow, and introduce harder light. It's an Amazon-cartonage XD completely traps light, I'll clean & dry it tomorrow and then give it the last finish with white lackey. so far works well but I see the need to make it completely hydrophobic.nice little veg box you have there with some very healthy plants.
Ok I think I understand. You are saying that your Amare light is much better than HLG because HLG has a bad spectrum that doesnt grow plants but you dont want to say that here to not upset anyone right?In a few weeks when I'm done trimming Joe.
You read my posts supposedly.
So far i can only vouch for what i use & what i know. You read so you know i share the knowledge as i become aware.
What i know is that companies are just now seeking the Spectrum I've been using for 5 years. In top-bin, high end builds.
And everyone is discussing the benifit of it everytime they discuss this & other gap fillers to the Original McCree Curve (300-780nm+)
Now that They are getting there this company i use is refining that original spectrum from 7 yrs ago.
Components + Build Quality.
Go from there Joe.
is this really true?because HLG has a bad spectrum that doesnt grow plants
Nani?is this really true?
Randomeblame gave an example here.there is a formula floating around, @Rocket Soul do you have it at hand?
i came out with 5min 6W on square meter with over 3qmol a watt efficient 730nm`s.
over a few percent far red all day are are a lot, its quite powerfull.
I should rephrase that, They work but Amare is 30% better because they have far red according to hybridwayis this really true?
should be pinned somewhere.Randomeblame gave an example here.
UV Suppliment Lighting
Thank you so much, that post should be stickied somewhere... OK so we are looking at a considerable addon of power... The 300W unit you chose is quite convenient as that is about what I use over my 2x4 trays. So we are looking at 300+25+50... = 25% additional power draw. Do you think the gains...www.rollitup.org
i think youre right there its the green which keeps the inner canopy happy.In the video Bugbee showed green can also penetrate a leaf fully just like FR, but you're right it doesn't compare to FR.

JG go and have a look at Valoya brand for a spectrum centred grow light, they have research papers and such, its a good read. If you then wanna start a discussion on it just make your own thread. Dont start the my growlight is bigger than yours discussion here please. Everyone else is able to discus far red on its own merits here and there is no need of bringing in brand comparisons. A lot of people use this thread for reference dont mess it up, please.here we go again good thread spoilt -
HI @Airwalker16 are these 3W monos? I've seen some for sale at very a very attractive price, and if a 4x4 only needs <20W they will be cheap to run too, no matter what their efficiency.I have 6x 730nm monos per 4x4.
Yes sir. 84¢ a piece already mounted to a star PCB at some places.HI @Airwalker16 are these 3W monos? I've seen some for sale at very a very attractive price, and if a 4x4 only needs <20W they will be cheap to run too, no matter what their efficiency.
the study was very interesting to read, because it went in detail explaining some of the errors the scientists of the past had been doing. Some of the information actually confirms my point. I also think that some is maybe not so relevant. For example there were alot of studies cited that had been research on very small growing plants - so the penetration power of the light doesn't play a big role at all. Imagine you have a good penetrating lightsource where a fraction of photons are hitting the topsoil instead.on the other hand were trying shape our plant to our needs indoors and it seems green can have a slightly negative effect on yield.
ive found the studie.

Despite decades of research, the effects of spectral quality on plant growth, and development are not well understood. Much of our current understanding comes from studies with daily integrated light levels that are less than 10% of summer sunlight thus making it difficult to characterize...journals.plos.org
