I'm saying a gallon a month is just a safe bet. You would never run out of room with that rule. And Cervantes may be a crackpot burnout, but he still knows a lot about growing...

And as for the not growing anymore once you change the photoperiod, a pure sativa will keep growing upwards. But if you have more than 30% indica in your blend, you're not going to see dramatic change growing up after a 12/12 switch.

Sorry for the confusion...
jon.hatcher Reviewed by jon.hatcher on . pot size question Greetings, I am in week 5 of vegitive growth, my very healthy plants are currently in 2 gallon buckets and growing very fast, they are only 8" to 12" tall but have been LST'ed into bushes and are free to grow vertically now. My question is: Am I going to be OK in 2 gallon buckets if I put (can't remember the name ) those clay balls used in Hydroponics on top of the soil, so all the soil is used by the roots therefore utilizing the entire bucket space for roots. Or should I transplant Rating: 5
