If you absolutely refuse to use leca, you may be able to get away with using other rigid, inert materials for this technique. Lava rock might even be acceptable for this purpose.

Thank you.
I have looked into SH some. Would you say it has any benefits over self-watering using a closed reservoir and a wick?

I don't know what your water tests out like (and couldn't help you if you told me, but lots of others here could). I also have a problem with RO water waste. It bothers me to see so much go down the drain. When I had aquariums set up I used the water changes, but that doesn't help with a reef aquarium. In the summer I use water from my pond. I try to usually collect the runoff from RO, and use it on houseplants who don't mind.
With a 100+/- orchids, almost all in S/H, it's a LOT of water. The past few years I decided to only water orchids that were sensitive (paph, phrag are examples) with R/O and use tap water on the rest. Plus I'm getting older and can't schlep around water like I used to. So that's a thought... research which orchids tolerate or prefer your tap water, and only use R/O on the ones that require it.
There's an OB member here who uses lava rock a LOT. Can't remember who. Hopefully they'll chime in with their experience with it. |
I understand and don't mean to imply that I'm looking to or willing to withhold water. I suppose I just feel that I may have overstepped with the amount of ventilation in the pots. I mean... if I'm honest, I'm just super jealous when I hear of folks in similar climates that don't have to water up to twice a day in the summer, (namely, Ms. OG).
That is definitely a good idea as far as using tap for less sensitive orchids. Why didn't I think of that? Because I'm scared of the TDS meter reading at nearly 400. Plants, fish, and humans alike use filtered/remineralized water around here. However, I only know for sure that it's full of nitrates and calcium, so who's to say it's very bad for all orchids? I will do some research and probably test it out on a noid Phal or two. Thanks!
Oooh... I hope the lava rock expert can chime in. I'm particularly interested in its wicking and moisture retention properties... versus lecca that is. Idk, lecca annoys me but I suppose the problem is that it floats and rolls, and I will deal with that if it's best for the 'chids.
