i have been starting seeds indoors at the begining of march.once the plants hit 10 inches.i turn the lights to 12/12.one week latter the plants start to show sex.i kill all the males(keep a few for breeding).i move them outside april 15.you can pinch the tops to bush them out or keep letting them go for a single main cola.give them a nice dose of fertilizer and your good.bye pinching the tops to get a bush. the plant revert to vegging a little faster.after a few weeks all the plants should revert to veg.plus your only using females.saving lots of time and money.very rarely does a plant want to keep on flowering.be diversefied,grow lots of different types of seeds.
