I??m assuming there must be a difference (or you??d be using dwc), but could you explain what the difference is??

thanks much
The grow rocks are the medium, the 5-gallon bucket is the net pot of sorts.
You can grow very big plants that way, but you need room for them to grow. It takes 2 5-gallon buckets one as the net pot with hundred's of holes drilled in it for drainage in the bottom & side's. The second bucket is the catch bucket. Now this is where is can change, you use a second bucket with the bottom 2/3 cut out and removed. It's just to raise the height of the first bucket I call net pot bucket. Then you add a third bucket that catches the run off and returns the water back to the res. In the third bucket you can place air stones, to hold them down you can use a 6" or 8" net pot upside down. The weight from the first bucket will keep it held down and the air stone in place. That is how you start growing KBS but there is so much more to KBS growing then that. That is just the bucket system for KBS growing. You still need thousands of dollars in parts, pumps, lights, & equipment but that is the basic of KBS buckets.
Zandor Reviewed by Zandor on . Zandor Should I trim roots? A friend-of-a-friend has an aero tube setup using 6? diameter pvc tubes with 3? netcups in them. At a certain point, the roots were no longer hanging from the netpots being sprayed anymore --- they??re laying in the bottom of the tube (in approx 1? of flowing water). It seems to defeat the idea of aero if the roots are submerged; now it??s basically just a NFT system. Plants are about 1 foot tall, roots about 1 foot long, flowing in the direction of the drain. I want to trim all Rating: 5
