thanks unreg, same to you bro. theyre 3.4l, just under a gallon though I'd like to step it up to closer to 2 gallons, just haven't yet, if it aint broke and all...lol. the stakes work good for me for the way I grow, like tp was saying about nets, same reason I don't scrog, they allow me to move things around. a couple tops are always higher and staking allows me to position the highest tops to the outsides and put my shorter plants in the middle to try to make better use of my light.
