You probably can't see it but theirs about 3/4 inch seedling started and I was wondering what height to hang my light above it(I'm using the mars hydro ts 600). And yes I know the other two little plants pathetic.
I have purchased organic soil it's in the pot that doesn't have a sprouts in it but that's are autoflowers so I don't think the photoperiod will be a problem.
The frame is 20×30 and it is 45 inches tall.It is not airtight at all and all it is,is mylar stapled to a wooden frame.How well will this hold heat and humidity?
