Lighting question.

[Gordo41]

i have 5 Cree3590 COB lights i want to put into my 30"X30" tent.
i'm trying to figure out what the best paturn/ spacing would be to give the most even lighting over the entire grow space.
here is a chart that shows the PAR readings for that chip at different inches from the center.
i think it was measured from 18" above the surface.
Any opinions?

i cant post the chart for some reason,, ill try in another post.

I am not familiar with the lights you are talking about, but 5 lights of any kind in a 30"x30", I would put one over each plant a nd let the overlap help adjacent plants.

I have noticed with normal led lights 600w 1000w 1200w they work great for 2 plants in veg but once the plants get big goin into the flowing stage one led light per plant is what is needed because the led lights do not angle out the light very much and it's not enough for the auto flowers that I am growing I am noticeing I need 1 light per plant becuase they take up more room than the light can spread out

These are not like the red/blue leds you see for sale everywhere. In fact i have a MARS2 400w light in the tent right now, and the new one should be twice as powerful.
not in watts but in output.. watts are almost useless when it comes to light out put. It PAR you need to look at if your going to buy a light that really makes great buds.
this is a 3700k light, no red or blue , but if you look at the spectral readings you cat see that it has a lot of blue in it, enough to be used for veg and flowering.
i also though maybe i should put a light over each of the 4 plants i will have in the tent, and be done with it. But what fun would that be,, I mean, if you cant mess with it for a day or two what good is it?
