It is pretty cool. Its all new to me, Psilly one. Been growing less than a year.
I think the two 6 gallon res Octopots with auto-fill (not hooked up - but see some plumming) were $200 with shipping. Thats with Grommets on Rocket sleeves as well.
At this point, Im already geared up for another Octopot grow with Rain Science grow bags. Im really hopeful for that one.
I would definitely recommend Octopots, but there are options for Sleeves/Growbags that may be better that what the company offers.
Check out the thread I started on it!
