I'm trying to find my pics. But it is a pretty simple thing to do and without soil.As long as the swamp is a freshwater swamp.the only soil you have is the soil the rootball is in.Or you can cut the bottom out of a bucket and set it in the block.You then bore a smaller hole in the block of cammoed-up styrofoam,about 1 1/2 inches or 2 inches, that way the roots will make their way to the water.The swamp water is rich in nutrients.You now have a mobile hydroponic garden.They can be moved to the direct sun or moved to the seclusion out of site of the air wolves.I have sum pics of a swamp grow I did.Just gotta find them.I'll be sure and get them for you as soon as I find and scan them.

Ga Grown!
