1. This is my first time growing. How much can i yield in total dry weight from this grow?
2. Is it OK to transplant to 5 gallon containers since i already put them into flowering?

do not transplant ever after 2 weeks b4 flower.stress stresssssss

oh dam.. so do you think they will last in those 1.5 Gal pots they're in now?

i would take the hit on the stress and xplant them into at least a three gallon pot. rule is, you want one gallon of soil per foot of verticle growth
