my plants are about 21 days old or so from seedlings. they have grown very well up to this point. I have successfully trained them all and topped one for fun.heres a pic from day 18 I think. heres my questions. can I put them on 12-12 with the daylight cfls I have now for vegging and still get them to show sex? How long should I wait/should I wait until after they show sex to transplant to 2 gal pots? can I use the same soil theyre in right now with newer soil when I transplant? when using larger pots, does that mean you should use more water when watering?
