Dr. Jacob Mittleider, who taught me, has built these all over - in 27 countries - and he discovered that many folks don't have or can't afford electricity. He also knew from his 20 years as a nurseryman that good air movement was essential and heat rises, so he designed the greenhouse with 1/2 of the roof taller than the other, and an 18" gap between.
By putting the greenhouse plastic - or polycarbonate - depending on what you're covering it with there,attached at the top and on hinges (polycarb), it can be raised varying amounts to adjust the amount of air, and will very quickly cool a greenhouse that is getting too warm.
In very warm weather the same concept is applied to one or both side walls, to give almost total ventilation, and no heat build-up in the summer.
Jim, this looks like a good plan. I would love to see the entire Adobe document. To steer us to it, you need to open that page on your computer, highlight the web address in the address bar, click on Edit, then copy. Then open this thread and hit Edit, then paste. It will show up as a Hyperlink and should take readers to the website when they click on it. Give it a try! Thanks!
I would really like the plans for this greenhouse also. My son in law and I have been discussing building one. This one looks great.
If you can email to me that would be great, it you are not familiar with how to do attachements let me know and I will give you a crash course, its really easy.
thanks so much
Me too, are ya gonna post them. I cant have a big one but even a teeny one would make me happy as a clam. Im assuming I can make a few changes with help from DH to make a size we could both be happy with.
I got the plans that you emailed to me and just wanted to say THANK YOU!!! I am only going to use the plans for my own yard... finally an easy plan for a sturdy greenhouse that my husband is even excited about!
We probably won't build it until Spring but I will try to post pictures when we do.
Jim, I too received the file and want to thank you. I am particularly interested in the roof vents. We are planning an addition to my current greenhouse and think this feature can be incorporated. Also we will completely insulate the north wall and the raised section of roof, because we have absolutely no direct light from that side. If painted white inside, it should reflect the light pretty well. I have a Northern Lights GH now that is insulated on the north and am very happy with it. Would buy another one, but the price has doubled since I got mine!
I am really embarrassed at how bad it looks this year. My only excuse is that I've been occupied in caring for my sweetheart of 42 years, who has been through 10 months of extremely difficult cancer treatment this year. Please forgive the appearance - inside and out.
Thanks for posting the picture of the greenhouse even though you are embarassed about it's appearance. It looks good to me. To everything there is a season, I hope your wife's health will improve quickly.
Thanks for the kind expressions from several of you. Eleanor is getting better. Her hair is re-growing, and her strength is returning. She can walk about 1 1/2 miles each day. lymph-edema in her left arm is a problem that we hope will improve with time.
This is a little off the subject, but if Eleonore is on tamoxifen, you can get it much cheaper from Canada than here in the US. I have been getting it for my Mom from Minit Drugs https://www.pharmacy-online.ca/brand/index.jsp
...hope they don't send ole Ashcroft out to arrest me!
I just now requested the greenhouse plans PDF in a separate email. Is the wood in the framework of the greenhouse treated wood? A lot of greenhouses use an aluminum frame with the idea that it won't rot or rust.
With respect to the wood issue, I discovered recently that the pressure treated wood here in our local Augusta, Maine Home Depot is treated with a copper arsenic compound and each piece of the wood has a red warning tag stapled to the end grain. The tags warns of the poisonous nature of the arsenic and warns against skin contact and warns that the arsenic can leach out into surrounding soil (in the case of the landscape timbers).
I also heard that it will be illegal to sell the arsenic treated wood in the United States after the end of this year and that the new treated wood will use something "presumably" safer.
I put "presumably" in quotes because back in the 70's when I had a big Fort Worth garden, I used railroad ties as an edging for the garden. They were used and well-weathered, but they had been pressure treated with creosote (which seemed to go all the way through the ties) and the creosote was later said to be carcinogenic.
I am surprised I am still alive. As a kid it was my job to paint the interior of the chicken house with creosote to control poultry mites. I even took some cough syrup (Creomulsion I believe it was called) and cough drops that had creosote as an ingredient, and later used a bath soap and antidandruff shampoo that contained creosote.
During the 70's and, I think, the 80's, the lumberyards were selling pressure treated lumber that contained pentachlorophenol or some such thing. Later "penta" was found to be carcinogenic and taken off the market.
As kids on the farm, we sprayed our irish potato plants with arsenate of lead to control potato bugs and larvae. What a double whammy! Arsenic and lead. And both are cumulative poisons. The times they are a'changin'. Hopefully for the better.
But so far, no safe pressure treatment for wood has been found. That is why I am a little skeptical that the new 2004 treated wood will be safe. Hopefully they have finally "got it right." Anyhow, that is why I do have some concerns with the wooden frame for the greenhouse.
here in the deep south, Cypress is cheap, available and suitable for most building projects requiring weather resistant/rot proof wood.
As far as where it touches the ground, that is easily solved.
dig a three-four foot deep hole for the post, pour 4inches of gravel, and than pour a concrete pad in the hole for the post. set the post on the hardened concrete and pour concrete around the post... thus no dirt really sits against the wood.
a little creativity goes a long way.
Burton, your stories remind me of my fathers tales of how they'd spray ddt on themselves to repel mosquitos... I'm sure it worked pretty well tho despite the obvious health issues.
I pour a small cement footing, put a metal stirrup in it, then place the 4 X 4 wood in that stirrup. Therefore the wood never touches the ground. Also, we recommend you paint the wood white - which reflects more light, and helps preserve it as well.
This is a greenhouse I finished building last spring. I got some awnings from a building teardown. When my husband and I saw the awnings lying by the dumpster I asked him, "what do those look like to you?", he said they looked "like a bunch of tents." (He doesn't garden, , , doesn't go camping either come to think of it). I tho't they looked like a greenhouse roof,,, and I was right. As soon as the green canvas was removed and the frame was painted white and covered with plastic, and many other steps were completed, it became a 12 X 20 greenhouse.
I wish your wife a speedy recovery, and my best wishes to both of you for a wonderful 2004.
Very nice lesli is the covering polycarbonate I can't tell from the pict. But where is the entrance for the cat. Two cats and 11 quail the cats really don't bother any thing and the quail are caged. Nice nice job. Ernie
I love that one,and I am curious about the polycarb.
I have been thinking of replacing my platic with it,section by section,just not sure how to peice it together.I'd start with the roof one year ,a side the next...
For those of you in cold climates - even up into Canada - you can make the greenhouse very weather-tight and inexpensive to heat by using dual or triple-wall polycarbonate on the outside, and then lining the inside of the greenhouse with 6-mil greenhouse plastic.
Another "trick" is to start your seeds in a smaller "greenhouse" within the greenhouse. section off a small portion with plastic and put the heater in that. An area large enough for 4-6 flats can get an awful lot of vegetables growing with little heat wasted.
Once they are up and growing, they need less heat than they do for germinating.
The picture is a large greenhouse of the Mittleider design at 54 degrees North latitude in Russia. Anyone care for tomatoes?
Many of you are aware of our member Jim Kennard, who posts threads related to the Mittleider Method of Gardening which he teaches all over the world, mainly in Third World countries enabling those people to feed themselves. He has just lost his wife, and here’s the note:
Date: Wed, 08 Sep 2004 15:48:54 -0000
From: "Joe Kennard"
Subject: Death in the Family
It is with much sadness that I inform the group that Eleanor Kennard, the beloved wife of Jim Kennard, passed away last night.
Eleanor and Jim have fought a long and courageous battle with Breast Cancer for several years and today she is released from the intense suffering she has been enduring.
Services are slated to be on Saturday, Sept. 11, 2004 at noon.
I am very sorry for his loss. I lost my mother from breast cancer and my mother in law to lung cancer. My family and I will keep him and his family in our prayers. I found comfort in knowing that my mother and mother in law are no longer in any kind of pain and they are with our lord in heaven. God bless you all.
Due to Jim Kennards recent loss, I don't want to bother him. The link in the "extras" doesn't work for me and I didn't find a link at his website.
I wonder if anyone here would know how I can get a copy of the greenhouse plans he offered last year.
I sure would appreciate it if I could get them. I don't think there is any other way I could afford a green house. Being retired limits my income. Any and all help would be appreciated.
Thanks in advance if you can.
I don't know if this will help you, but I did a google search for Jim Kinnard Greenhouse and found this site, which gives directions for a greenhouse. Jims photo seems to be in the same GH as posted with his photo above...Hope it helps...
Thank you for your reply. I finally got the plans. Now I have to learn to understand construction. A greenhouse is something I have dreamed of for years...but then don't most gardeners want a green house?
Belle, I am so glad to hear that they were the plans you were looking for! Please post as you go along and do your construction. I am getting a little hoop house for now, but would like to know for the future how easily/hard this one goes up! I am sure I will be needing more room soon.
It is too late in this year for me to get it going. I am looking forward to next spring or perhaps next summer before construction begins. I have too many irons in the fire for now...(I always do..so what is new)
When the project is going, I will post about it.
I would love a hoop house now...just for little ol me so maybe you can post about how that is going. I haven't built any kind of greenhouse yet...and the big one Jim's plans are for is not entirely for myself...
My hoop house has three walls and wasn't completed before a windstorm blew it over like a kite. The plastic was all torn up and my husband jsut threw in the towel and said we needed to "move up" before we even finished this one. I will need to have a greenhouse this winter and am certainly considering building this one.
Jim, I just printed the plans and will review them and I was wondering if these are available in spanish? I know some great framers and they could be hired to make this for me, but they only speak spanish. I was thinking that maybe since these plans have travelled the world there might be such a thing? Thanks
I tried to download the plans but my printer is not working.Can someone be so kind and send me a copy? I will pay postage and whatever it cost to print it out, just let me know how much. Thank you very much.
Can't find any link anywhere. Even on Growfood.com the link that says "greenhouse plans" really ISN'T. It's just greenhouse info. I joined Dave's for the Mittleider plans and now can't find them anywhere. I am hoping someone can help or I've just spent 20.00 I could've spent on Mittleider books/ebooks.
