I love growing avocados but when they matured past the cup-of-water stage, i kept forgetting to water them. So I invented this little seat for the avo seeds to sit on so that the roots can grow below into a fish tank or any container of water. The fish tank works really well tho because the plants need nitrogen to grow and the fish make plenty of nitrogen. I suspect that the nitrogen levels produced by my fish are providing enough nutrients for the baby trees to grow through adolescence without actual dirt.
fits over the edge of any standard aquarium and the seeds sit just below the water line.
can use supports if you want but not necessary
