yea id say youre good to go. just keep a light that big far away enough so you don't burn them. what kind of soil. is that in?
at 3 weeks better to potup now for that 1kw of explosive growth, and yeah add 30% perlite to that forthcoming 3 us gall. pot to prevent nute burn and root compaction, but if you have nothing smaller hang the light at about 9-18 inches is good, but you are wasting electricity
I got kinda lazy and didn't buy seed starter which I should have, they are currently growing in EBO stone organic soil, the soil seems to be a little hot and is burning some of the plants which also brings up the question when shoul I feed them?
if the soil is too hot you shouldn't feed them anything but water until the nutrient source is used up in the soil
