    Green house

    I've been considering building a green house in the spring. I've seen several folks recycle old windows to build them, but I think this is one of my favorites so far...


    The ReStore had a contest going on in the spring for creative uses of recycled materials, here are the rest of the pics...

    That one looks great. I'd really like to get one up to help with our short growing season out here.

    I'm thinking more along the lines of just one slanted wall of glass, with a big cinderblock type of heat sink on the north side to pick up the heat during the day. Haven't seen too many designs for that though.

    That one is a little more involved than what I was considering, which is a pvc hoop type over two raised beds side by side.

    Did a small hoop house one year. If I don't get a real greenhouse built, I'm thinking we'll do just a little bigger hoop house and see if we can't cover at least 4 of our 4x8 raised beds.

    I did the small hoop houses this year and they worked great, so I just ordered the tube bender to do the larger hoop house. I like the temporary nature of the hoop houses, but not the cost of the plastic covering. I'm afraid a more permanent looking structure would get me in trouble with the county. This site got me started:

    I'm liking the looks of that a lot... I'd still like a permanent structure of some sort, but that looks like it has a higher chance of actually getting built...

    Thanks Ted!

    Brent,

    I'm not sure you'd be happy with the growing conditions in one of those. They're fine for extending a season a few weeks on either end, but for serious greenhouse stuff they leave a lot to be desired. You couldn't, for example, produce winter vegetables.

    For that, you need double walls, and wood makes it easy. Build arches out of treated 2x4s, and use the same film they're using, but inside and out. If you have a pond inside as a heat sink, or even a couple barrels of water, you can heat the whole thing over night with just a candle, even in winter. I did that in middle tennessee, where winters are worse than yours.

    There's no reason you can't have fresh tomatoes year round, or just about anything you can think to grow. And it'll last for years. Mine lasted until a tornado dropped a giant hackberry tree on it...

    Thanks,

    Bill

    bill how does a candle make a green house warm enough to grow in the winter with just a couple barrels of water ??? in my parts those barrels would be frozen by the second night for sure??

    Point well taken Bill. I plan on using tunnels within tunnels to extend my season. Here in coastal Virginia (zone 7c) I can usually overwinter greens like Kale and Swiss Chard without much cover. Last year I tried Beets and Carrots with no luck. I'm thinking that by using some of the tunnel within tunnel techniques that I can grow later and plant sooner, with only a month or so of really bad temperatures. I ought to be able to do some fall crops and not have them wiped out by a few bad frosts. It's worth a try...at not a lot of cost.

    Ted thanks for that link. Real interesting manual.

    I had a friend in SA that grew cucumbers in a unit like that. He did it kinda hydroponically with a drip system and growing in sawdust filled bags.

    Johannesburg is situated at 6000 ft above sea level and in winter it can get pretty cold so he had a blower and anthracite furnace that was linked in via a small plc. Plants were kept nice and cozy through the night. Of couse no snow so quiet different to NA.

    I have never looked around here but are fibre glass corrugated sheets available here Larry?? Dont know how if they were they would stand up in snow but how much snow would collect on a curve like that. I have no idea but i have seen many plastic film covered ones here in tatters.
