Ross and Susan, How are the vents locked? Being a computer guy I am always looking at ways I can use my computers to monitor and control things in my greenhouse. Is it a mechanical lock controlled by a solenoid or a magnetic lock? This idea has me intrigued, the idea of putting on heavier roof vents (suggested by Denise) that I could lock and use my computer to control when they are locked and the opening and closing of the vents would be in interesting project. If I combine this with a way of getting cool air into the greenhouse that does not give too much of a cold shock to my plants. This may require some work, but it sounds like a great summer project for me, as if I did not already have enough of them.
This is what I like about discussion groups like this, we can get lots of ideas from all over that can help fix a problem. This is what most of us want from the OGD. If Ross and Susan would not have brought it up I may not have thought of locking down my vents. thanks, Tom Hillson On Mar 22, 2007, at 10:57 PM, Tuckers Orchid Nursery wrote: > On Mar 22, 2007, at 17:27 PM, Thomas Hillson <[EMAIL PROTECTED]> > wrote: > > Mark, > > Unfortunately, I tried moving the air to the floor, but the times I > tried > it, my entire greenhouse went over 90 degrees, way to hot for my cool > growing species that I like to keep no more than 60 to 70 this time > of year. > If I did not have a varied collection of orchids this would be > easier, but I > have over 250 genera and lots of hybrids in my collection.
