How big are your netpots ?

Only reason I ask is cause it would be much easier to use hydrtron rocks instead. Any way with an airstone in the bucket put your plant in when you first see roots. The peat pellet will become your air roots and rootball. Bring the water up to the bottom of the netpot. Bubbles will splash on the netpot and as roots grow down into the water you can lower the water level just a bit. At first you may have to take water from rez and hand water alittle just to get the roots headed down into the water. This doesn't take long.

latewood has the best mix for GH nutes. It's a sticky thread here but you will be using all 3 nutes, grow, micro and bloom.
