Hey all! I have some sprouts going(couple weeks old), and I was wondering if once they get about 1' tall...or maybe a little more, if it'd be okay to put them on 12/12? Or would they still be too young? Cuz I just don't have the room for them to get very tall. Thanks!! =) -MysticGohan
you can put them on 12-12 at any time. however, you will get basically zero yield. mj plant need to reach maturity before they are flowered in order to produce anything worth fooling with. now, if you have clones that are from a mature mother that are that small and you flower them you will get a slightly better yield.
thanks guys!! when do I know they're mature? when they have a few sets of their full fingered leaves? or is there some other sign to look for?
They are mature when they develope alternating nodes. http://www.growkind.com/forum/showthread.php?t=23808
