Thats why I suggested using bubblebuckets, You can make them self contained systems if you use 5 gallon buckets and 1 net pot per bucket, its more work just like soil, but it grows a hell of a lot faster. And you build that relationship with each plant and plus it'll give you something to do everyday while making sure each plant is healthy and bug and mold free.
I believe that set-up is from someone on RIU but it is self-contained and doesnt connect with any other buckets, this is the same plan i will be using for my grow here in a couple weeks.
This guy has a little too much going on with his bucket, you really just dont need all that extra stuff to make a nice bubble bucket, just a pump, air stone, and airlines. All that extra is just for show. Ill post pics of mine when I get it all setup.
