I like using that LECA hygroton stuff. It works well.
Thanks! I'm looking forward to learning to make them all happy plants!
I'm only using the hydroton to hold the stakes in the net pots, none of the plants are actually sitting on it. Both the hydroton and net pots are supplies I've got for an aquaponics project that keeps getting postponed. Hopefully I'll be able to get that up and running later this year once I've moved to Arizona!
