I have 8 new seedlings at about 2 inches and they are under a T5 2x24 watt lamp right now, I have two 400watt lamps one is a MH and the other is HPS both are hung and ready to go. Heres my question- how long should I leave them under the T5? everything Im reading says transplant ASAP but they dont tell you how mature the plant needs to look before doing so. I would really appreciate any suggestions
I would wait at least a week, 2 weeks if you're patient. If you are patient with your plants they will reward you greatly http://forum.grasscity.com/general-indoor-growing/558350-how-far-hid-light-seedlings.html http://boards.cannabis.com/basic-growing/48973-when-does-seedling-stage-end.html http://hubpages.com/hub/The-three-wild-strains-of-pot A couple of links that may be of some help to you.
The main thing Im worried about is they are in a propigation tray, in a starter plug how long can they go in that small of area?
