Last grow i used 3 gallon pots & yeilded anywhere from 1.5 oz's to 2.5 oz's per plant,this grow im using all 1 gallon containers & am experiencing faster growth & i expect the same yeilds,i attribute the faster growth to the more frequent watering schedule delievering more oxygen to the root ststem.
The 3 gallon pots i used last time were a waste,there was a ton of room left for roots to grow & the plants were 3 to 4 ft bushes,my avatar pic is one of the colas from that grow,im stickin with 1 gallon pots.
