| I'm shopping for heaters, now, and I'm cogitating a way to put in a hanging shelf, under the benches, for seedlings and lower light plants (paphs, phals...). -Cj |

| One thing I would suggest now that winter will soon be upon you is to buy bubble wrap to cover the GH for insulation, otherwise you'll clock up high power bills due to the inefficient insulation of the plastic. If you go to Cynthia's web site you'll see how she's done it. I'd show you mine, but I took it all down this morning as we are now starting to get day temperatures in the 80sF and night time down to the high 50sF.

| Oh yes, I know. This isn't my first time around the greenhouse block. I have been in the orchid game for a while, after all. Then again, our average coldest night of the year is only in the upper 20's F, and even so, only a few nights like that happen every year. Our biggest worry here is more about the high temps in summer. I'm going to let it get through the first cold snap and see how well it holds heat, then decide it I want to go through all the trouble of putting up the bubble wrap. Mostly, that's because I don't want to have to go searching through the barn at my parents' for the rolls of bubble wrap I used on my first GH. Honestly, I've had more problems in similarly covered greenhouses with the temps getting too high. Haing an 80-odd degree days that result in a 90-odd temp in the GH. I'm willing to pay a little more for the heating for the 12 or so days that I will really need it, so as to avoid cooking things when the sun decides to just beat down on a winter's day. My first GH had a similar exposure, and I cooked a couple plants because it rocketed up to 95F inside the GH once the sun hit it. It had been all tightly wrapped for the 30F night, and boy, it got warm that day. I only wish the weather here was consistent enough to batten down the greenhouse hatches. It gets kinda hairy if you get a solid week of cold (we often do in Feb or Mar), but it is not uncommon to see the 80's well into december. So far this fall, our lowest night has been 38f. I don't expect we should see a hard freeze before the end of November, and by then only one or two light frosts. I'm climate Zone 8, after all. Miami is only Zone 10. We're marginal to Zone 9, honestly. About even, latitudinally to Tampa, Florida. -Cj Last edited by Orchidflowerchild; 11-11-2007 at 11:47 PM. |

| Getting too hot will be my problem. I live in the desert where it can get 125F in the summer. It would be nice to have a greenhouse for the humidity and light, but the temps are brutal. Jay |

| Here in Adelaide, South Australia, like you guys in the desert, we get extremes too. The past week has been dropping down to the bottom 50sF but during the day from 80 to 87F ! So, I took the plunge and whipped off the bubblewrap this morning so that it just a shade house now with 75% shadecloth. At night, I might just throw a sheet of construction plastic over the top to keep a little bit of warmth in.

| Digitalgate: I rent a mobile home and the plot on which it sits. The space I am alloted it 30 feet from the house in any direction. A small hobby greenhouse does not nexessarily require acreage. -Cj |

There are some random things outside the Laeliinae that I definitely want, such as some of the Spatulata Dendrobiums, I definitely want another Den. spectabile, I like Tolumnias, and of course Stanhopeas, Gongoras, and Coryanthes. For now, though, I'm focusing on building a cattleya collection. -Cj |

| Orchidflowerchild: Congrats on your new GH. Oh..........how I wish! I'm sure you'll be busy filling it up soon. Can't wait to see your additions. Also, be sure to post in our "Growing Spaces" thread to show off your new greenhouse.  |

| Well, I assume you will be putting up some shade cloth that will help with the heat. I take mine off during winter, and back on in spring. Now about the bubble wrap. I found that the shipping store stuff that only last about 8 months is really great to diffuse the light, and allow my orchids to go to higher light levels before I have to worry about burning the leaves (the agriculture equivalent doesn't diffuse very well). This is what I am trying to find time to put up in my GH for winter, not for insulation, but to help diffuse the light to prevent burning with the removal of the shade cloth. In summer, I don't think there is any downside to having the bubble wrap up because the cooling in the greenhouse is done by ventilation, not by heat transfer thru the walls, which is insignificant. If you have heat problems in summer, I think the only answer is an evaporative cooler blowing thru the wall, tho I have never been in high humidity areas, so that may be different.

I have been reading up on rupiculous Laelias recently and have acquired an interest in these beauties. Do you currently have any now and if you do what are they growing on/in? Do you plan on mounting them or growing them in a pot medium. I was reading that some of the successful growers of these were using coarser lava rock on the bottom of the pot and topping off with fine Aliflor.
