my 2nd time grow set up consists of
3 pails 2 net lids and 1 lid
1 inch hose. About 240cm.
4x 1 inch bulkhead fittings.
1/2 inch tubing. About 120cm.
4 outlet air pump.
Small air pump.
5 air stones.
Silicone sealant for construction of leak proof set up.
From experience would recommend bigger bulkhead fittings for more water flow. Have had a few floods.
Think this would be One of the best ways for set up. I got 2 plants growing and the third pale is for checking water
