I’m going to take a minute to explain the floating gardens because i keep referencing them and i don’t want anyone to be confused. the design from the floating gardens are basically an extreme version of the self watering container taken from The Urban Homestead by Kelly Coyne and Erik Knutzen. Instead of the plants being watered from a second barrel, they will wick water up from the lake.
I’m planting everything in plastic storage containers some bigger than others depending on root depth. The bottom of the containers will be right at water level. There is a hole in the bottom of the containers that has a chinese takeout container with holes drilled in it. Dirt will fill the containers and be moist without being over saturated. (hopefully)
The frame that holds the containers is a basic 2×4 frame with two 55 gallon drums to keep them buoyant. The straps that cradle the containers and the drums are adjustable in an effort to keep everything at the perfect water level.
The only thing that is unknown is the water quality of the lake. It’s being tested right now but we won’t know for a couple weeks. It is possible that we could grow the food and not be able to eat it. I don’t know if that makes things any clearer. I drew a picture while my kids were painting I hope it helps.
