All my orchids are growing on windowsills, but now, due to the large amount of plants, I decided to grow them in a kind of greenhouse( the ones that we can find to home depot, just to say).
I was just wondering what kind of LED can I use. I've found one with this written on it: T4, 30W, 2100 lumen.
Is this good? I mean, is it enought to grow my orchids? How many orchids can I grow under this light?
