Turface in a Self-Watering Hanging Baskets
I have a number of spider plants that I keep in hanging baskets indoors. Rather than take them down every time I water, I've found a style of self-watering basket I like, with the opening to the reservoir near the base of the container -- so I can hang the baskets above my head but still easily refill the reservoir.
In the past, I've used straight potting soil in these baskets. Last year, I tried switching to Raybo's 3:1:2 mix, which also seems to work well. This year, as I add a couple more plants, I keep looking at the turface I have around for the gritty mix, and especially the turface fines I've sifted out, and wondering... Would it be possible to build a self-watering mix using these ingredients? It'd be nice if I didn't have to restock the potting soil and/or the perlite... ;)
So. Has anyone tried this? Can anyone give me some suggestions on how I'd go about figuring out proportions or testing a SWC mix before actually trying a plant in it?
