Shadecloth question

I find that I can grow my Oncidium with my Vanda while my Cattleya do not like that much light.

With plastic over the shadecloth I think your problem stems from lack of air circulation.

Wind currents in Florida are North to South and that is the orientation the greenhouse should have. It needs to be able to be opened at the ends for circulation. If you can not open them, then strong circulation fans are necessary.

Your rot problems I would think stem move from lack of air movement then from light levels. Too much light would burn the leaves not rot the pseudobulbs.

Gage: Hi, I use charcoal and lava rocks, I going to see if it works, today I noticed that there are some pseudobulbs very brown and they have a tiny leaf growing on top. Let's hope for the best.

Ok just make sure you have something that holds moisture like coco husk chips. Just charcoal and lava rock will be too dry, even if you are watering daily.

Ha!. Today I found an oncidium very ugly and going down, but I looked inside the roots and there it was, tied inside Sphagnum Moss, very wet, so lets see, I removed it completly and hope for recovery.
