so i have finally got my new lights on the way. hopefully i have it right. Very high efficiency 3 umoj/l . will have to measure myself to see if that is right. Also brought a par meter. checked the par readings and no wonder i have been have trouble with size and weight. top of canopy was at around 2200 umo/l. the plant never showed any sign of a problem. letting it grow up to light is deceiving.
So this is were i'm at. i've got a chinese company making me a light. 300watt (true watt) , 3000k , 660nm (ri) 1, ir&uv , 301h diodes. what do u thing ? anything else you thing it would need?
so uv is hard to get now. UV 's chips lifespan is not as good as the rest. mate of mine was saying the 660nm relative intensity is very important , 1 or over? (i have not see this for true but he was saying 4 grams a watt.)
so i'm looking at a new LED. (Top Bin Samsung LM301H 3000k mix 660nm deep red ). only thing with this light is, it makes no mention of uv or ir. is this what the 660nm is?

top of canopy should have read 2200 PPFD.

I'm chopping and changing at the moment. But I will send you a couple which are on the short list.
So i definitely need the uv and ir?

Thank you. Would have to be one of the best explanations of LED lighting terms i've come across.
