👉Plants starting to gain traction and growth is looking good. The glass stones show the surface algae, the algae isnt growing, and has stained the light coloer gravel in the media mix.
I use those same racks. I drop ropes over the rack into a 1 gallon ice-cream tub, then set the plants on the ropes for wicking (rather than as a catchment for runoff). Hadn't considered the tennis balls on the feet, that's a good idea. 👍
