I guess I put my growing area description into the wrong forum, but here it is, in the right spot! My greenhouse is an 8 x 16' lean-to off my bedroom. It is under a slatted patio cover which provides 50% shade in summer and lots more in winter. Recently I reworked pretty much everything: added an automatic sprinkling system with fertilizer proportioner, repotted everything into expanded clay in pots or baskets, mounted or re-mounted plants. I divided a number of plants and I am experimenting with mounting and potting with them. My greenhouse has natural microclimates, with a consistent temperature difference of 10* F from end to end. Winter lows get down to 50* and summer highs up to 90*. I have an evaporative cooler with an 8" thick pad that maintains at least 40% humidity, and with my sprinkling system it is usually around 60%. The indoor-outdoor carpet runner on the floor retains moisture for more hours. Believe me when I say the humidity is always a work in progress out here! I am blessed with lots of light, from 9,000 foot candles to whatever I can shade down to. I recently downloaded a light meter app that reports in lumens. I still have to work out how those measures compare. Anybody have a conversion equation? My sprinkling system comes from components purchased from groworganic.com. I tried a single programmable valve first, but I had too many emitters for my well pressure, so I moved up into a 4 valve system. Pure joy! Instead of spending hours watering and making sure I hit each of the 250 plants, I can spend hours looking at them, evaluating, cleaning, tying, photographing, etc. Having been a teacher, I know you have to provide each student with what they individually need, not just what is convenient. I figure it's the same for my orkidz. I'm not always successful, but that's the challenge of growing the most fantastic plants in the world!
