Well thats the only thing that might hold them back a little as we all know the bigger the pot the better. I grow outdoors in the ground so I dont have much experience with pots. I still think it will do good for ya. Next year get ya some BIG pots and grow em big.
Hey Dan the miracle grow bloom booster is what i use although most will tell ya its shit. Seems to work well for me so Im sure it will for you. I would probably go 1/2 strength for the first time or two get it used to the transition then feed away. Plant looks good by the way.
No problem GreenMeter I think your golden,those ladies will plump up nicely for ya. You may like it so much that you try a few outside again next year.
I think you will be good to go getting those girls out in the sun and let nature work for you. Looks like they are flowering so sit back and watch em grow and get ready for some good old home grown. Good Luck
