They will double and triple in size during flowering.......got a good tall ceiling right?

That thread of Stinky's should help you decide......I've had MUCH BETTER success with Stinky's method of transplanting several times vs once and would DEFINITELY recommend several transplants for yours.

My plants grew better, faster, healther roots, and just plain became bigger, larger, and healthier plants imo with transplanting into several containers vs just one.
Weedhound Reviewed by Weedhound on . First time, having problems Here is my situation: Closet setup, am using a HID florescent ballast for the growth phase then will switch to a HPS bulb for flowering. I have been running the florescent setup 24/7 for a little more than a month now. Plants are beginning to reach a foot tall. Started the seeds directly in standard "kegger" red cups which i cut holes in the bottom for drainage. I will be transplanting to a 6" pot once the plants start to show gender. (will also switch to HPS 12/12 at this point) Rating: 5
