Hey guys I got a 400w light but it also says 400sl what's the difference between the two and is 400wats to much for these seedlings Sent from my LM-X120 using Grasscity Forum mobile app
My opinion is that for plants is never too much light. Problem would be if this light give too much heat than it would burn leaves. The difference between those lights i dont know.
