So these plants a are about 3 months old. Its 6 inches tall and I've already hardened them off. So I got a couple questions. Firstly, for being 3 months old do they seem to be a little on the smaller size? I figured they be much bigger by now. Secondly, at this size can I transplant them into their final 5 gallon container? Lasty, if I can transplant them now, is it safe to bury them up to their cotyledons? Thank you.
