Hmmm.... you're right, Allison. Using those crystals in the bottom of cells is something that never even occurred to me.
Do you mix it in to your coir (after hydrating) or actually just place a few gels in the bottom then top with coir? Do you moisten the coir before filling the cells?
I'm sorry this is such a detailed interrogation, but was thinking of trying it on a batch of coleus cuttings. I'd have to get out and buy the coir first though because I'm ready to do a last batch of cuttings. (And there's just so much to do in the garden!)
