They work great, but then I have a garage in the basement that I can put them in. I also don't have 140 orchids to water thank heavens.

I only have around 45 so far

Years ago I had the water tested and it was 7. something. I can't find the paper for it. I was just reading before I got on the forum this morning an e-mail from Jerry Baker, you know the garden guy, anyway it was saying you can put lemon juice in your water to bring down the PH. Anyone ever heard of that one?

I have to haul water for my humidifiers and now that I am going to have to start hauling it for my orchids also it is going to get to be a pain in the you know what.

I have sometimes mixed the RO water with mine for some of my orchids, I probably should have done it more. I have been using Epsom salt mixed with gypsum for extra cal/mag. I think my David Sanders is still showing signs of deficiency.

I have heard that lemon juice can be used to lower pH.

What signs of deficiency are you seeing on the David Sanders?
