Help with new system.

Ok here it is, I am capable of having four large plants. I dont want to have sog due to # of plants per meter. I was looking at the undercurrent 4xl. It has the 13 gallon grow sites. Is this a good unit? My local hydro guy said go aeroponics. Any suggestion from anyone with hands on experience?

Go single plant nft.. If u look at stinkbuds new book. The plans r in there...

If your looking to grow some monster trees undercurrent works great, a lot of aero set ps are made for smaller plants, look at all the fence post spray units and such.
