Thank you for your comments. I'm gardening for the butterflies and hummingbirds so my main intent is to keep some nectar and host plants, both annual and perennial, alive, so I can get a jump on spring. I don't care that they bloom through the winter, but want to encourage them to begin growing in early spring before they would if planted outside in my beds. A rest period or slow down in growth through the winter is fine. I'll be using a heater, a fan and wire shelving, so as to permit the best air circulation for the tiny space. One long side will have a southern exposure, the door end will face east and the northern end will have a privacy fence behind it, which I hope will help block winter winds. I'm very new to a greenhouse experience so my expectations may be totally off. Mary Here is a link that might be useful: this is the little greenhouse I've ordered

I've been peeking in now and then during the market season, not much time to follow-up on anything then as you all know. My first GH was put up in 1998 (GH film 2 layers 50'x100' folded in half), sold that farm in 2004 and moved the GH with us to our new farm, put new GH film (2 layer) on then. Sure seems to me the GH film was much better quality back in 98, now it's just like everything else, cheaper made. This was the same kind/brand of GH film both times. This same GH was moved to a new location on our farm (closer to the house) and reused the same GH film that was on it. To this day that same GH film is still in pretty good shape. I would never use construction plastic, GH film is worth the money. DEB

Found one in Homebase; cover, or essentially the same greenhouse. Hope we get some weather above freezing for a day so that it does not crack when I try and persuade the cover over my frame. Brian

I'm in zone 8 southeast Virginia and am looking for a way to overwinter some marginal to tropical potted plants. I don't need them to stay green neccessarily, just alive! Last winter I set up a pvc-frame, 6mil plastic covered greenhouse with some large bubblewrap draped inside. It was placed on a brick patio facing south and protected on all other sides by walls. I also placed some bagged mulch around the exterior to try and prevent drafts getting under the plastic. While it heated way up during the day, unfortunately it still dropped down close to the outdoor temperature at night. So, this winter I want to try improvements. I assume I'll need some sort of heater and fan setup. Will a spaceheater style convection heater work or do I need something else that isn't bothered by the humidity? Or is there a cheaper/better method? How can I best seal the bubble wrap to the plastic wall? This past winter it mostly ended up draped along the frame when the tape I used failed. Would dumping mulch around the exterior seal it better than the bags, or do I need some other approach altogether? Any other obvious improvements? I appreciate any advice. Thanks! Justin
