Grow bags bulge when filled with grow media.amp;nbsp; The cages allow me to use standard plant trays to collect any runoff.amp;nbsp; Cages are 9quot; X 9quot; X 12quot; with a bottom raised 1quot; so the grow bags remain clear of the runnoff.amp;nbsp; Egg crate diffusers were cut to fit the bottom of the tray to minimize rust.amp;nbsp; Cedar shingles are under the trays to tilt them allowing runnoff to be pumped out with ease.
