Yea they are in 2 gallon pots right now because of the size of my closet, I was going to do 3, but now since the flowering process, has started, I am scared to. No root bound problems thus far, they are bushing out nice now on the 12/12. I will post some pics today. I am on day 6 now.

As far as soil I use the following:

10lbs Organic Potting Soil
4qts Perlite
1/2 cup bloodmeal
3/4 cup bonemeal
2tps of Dolomite
