Guess I had best stick with the 1 gallon size. My growspace aint gonna hold no full growed Christmas Tree

I got two growing fairly well in the AG but I'm afraid one is getting too big. No telling how big it be at end of flower. Too big for AG I think. Whut would you think if I moved them over to Hempy Buckets to flower? What would be the procedure etc? Thanks. Would sure hate to lose em..they are sorta like kids to me..sniff sniff. I'm have vegged thus far CFL lights even if it kills me and them I]m gonna flower with em too. I dont know anything about them SOB's etc. They both got purty good sized root balls.
