To make a bubbler, takes very little parts, had you read the faq you'd know this! Simply put, a plastic tub, or bucket, a medium air pump like they sell at target or walmart for about $10, and an air stone.

Simple concept here. You start your plants out as normal from seed, once they sprout I usually put them in a rockwool cube. then once the roots start coming out the cube it's time to move them to a net cup that's large enough to fit the cube and have some space for rock, gravel, coconut, or expanded clay pellets (which I use) around the cube. Fill the tub so that the water comes up 1/4 to 1/3 the way above the bottom of the cup. You only do this until the roots grow down into the water that's mixed with your fertilizer. Once the roots hang down into the water in the tub, you can lower the level down an inch or so below the bottom of the cup. Need to give the roots some air, other wise you end up with root rot and a big mess.

good luck, and read the faq... it'll help ya along!
