Orchid greenhouse in a basement - any advice?

[BotanicaExotica]

Most basements supply plenty of humidity. I highly suggest a hygrometer for any grow room. They are quite cheap. My grow room at my home, an efficiency apartment I used to call "The Bomb Shelter" is very basement like. In fact they call this a basement apartment here in New Orleans. I would say that your most important elements you need to be concerned about is quality of grow lights, and air movement. I keep my apartment pretty cool, and the few phals I do have grow just fine in 60 degree temps. Phals are pretty forgiving in my opinion as long as there is enough air movement to prevent crown rot, and low enough light.

I do find with the new COB LED grow lights I have much less issue with pests and disease because they cover a much larger part of the light spectrum beyond PAR. PAR is important, but other parts of the light spectrum really help with some of the issues of using florescent grow bulbs (increased disease and pests), and the prices have come way down. I use VERO29 Gen7 LED grow lights and the performance is phenomenal. The light is visible light is white, while being far more full spectrum than any grow lights in the past. I am getting unparalleled growth and flowering from my plants even compared to those in my orchid society growing in greenhouses. Some plants are doing things I have never seen before. For example, My angraecum germinyanum which is only supposed to get a single flower per inflorescence is getting two flowers per. I cannot find any literature of this happening. Not sure if the plant I have has some crazy genetics, or if it is these lights. I have only had them about 9 months, but have years of experience growing under florescent tubes.
