I am using a 90W UFO
led light on some tomato plants. I'm at about week 3 and there is great growth, I'll post some pictures. I'm hesitant to state its a success because im still so early on into it but the plant and root growth are quite impressive to me at this moment. The plants are bright green.
I have another post about leave curling but that I believe is a problem on my part and not the light.
