Hey thanks guys, I've been pushing those 3gal fabric pots and there seems to be very little difference between running them in 3 or 5gal. These went into the flip around the size I'd normally up-pot to 5gal's but I was going to be around and left them in the 3gal knowing I'd have to water more frequently. Sure enough within the first week once they started the stretch I had to water them every other night. I did a similar run last summer and noticed that the larger plants in smaller containers gave me huge efficiency from a yield per gallon of medium pushing them like this. it's a pita watering but if you're Ok with watering every other day you can get similar yields to 5gal pots. A little more work but I'd only recommend it in fabric pots as it's pretty well impossible to get them root bound the way the roots form in the fabric pots.
I've been running these fabrics for about 4 years and still have 95% of the original pots. I just run them through a heavy duty wash cycle and re-use them. I'll run 5gal's, I have some Panama's running that were going to be in there for 12-13 weeks so threw them in 5's so I could water every 3rd day. The environment can make a difference in how often to water, these were run under COB LED's and averaged 80F/50-55% RH throughout the cycle, running hotter might get some more evaporation and need more frequent watering.
