Yeah, I've been thinking of going to 5 gal pots. Currently I use 3 gal pots which many recommend for autos, but every plant I've harvested to date has been root bound - hardly any soil left, just the root ball. The last few harvests I've been growing 1:1 CBD/THC for a couple of plants and make oil out of them for my wife - she doesn't like the "side effects" of THC (poor girl). But I grow a high THC sativa for myself. I don't mind the "side effects" at all.I always recommend is running 5gal for autos
