I just joined the party specifically to add this comment, so hopefully it might help somebody. I have been looking at numerous different plans for cheap greenhouses online all day long. For the most part, I like yours best congrats! But I did like one idea that I'm going to steal from another site, and I think it fits in perfectly here. You can kill two birds with one stone. The simple idea is to take pieces of rebar that are about a foot long and then pound them into the ground about halfway, leaving 5 or 6 inches sticking straight up out of the ground. Then use those as your anchor to attach the interior pvc supports to. The pvc is a good snug fit sliding over rebar. I don't know how to link pictures and so forth yet, so I hope I can explain it well enough. But basically, this will help anchor the greenhouse down for stability, plus you won't have any PVC running across the "floor" to trip over in the middle of the greenhouse. Incidentally, scrap pieces of rebar can be found at almost any construction site and pieces like that are just trash to them. You can also get them for free from concrete plants. Again, they are basically a nuisance to what they do. (I hope this is still true. I know it was before, but with the recent boom in scrap metal pricing, maybe the rebar is now "worth" something to them.

In any case, I hope this might help.

I think you have suggested a spectacular mod on this instructable.

[kewpiedoll99]

Great instructable. I am planning to implement this or something slightly modded off it this weekend to extend my garden's growing season (for my cotton, in NJ!! Lest there be any doubt about global warming).

BUT I have a question as I am not too familiar with the pvc pipe fittings. Why do I need the threaded adapters? It seems like you only used them for the bottom pvc pieces; why didn't you need them to connect the pvc that arcs across the top as well? Thanks in advance for clarification on this point.

[paulcw3]

Thanks, this is just what we needed, and it came in at 20.00, we tried the pvc clips as earlier mentions by another post, and backed that up with some recycled hair clips, now when the freezing night come this winter we can save our outside potted plants :-)

[lmartin621]

This might sound silly... (I'm a first timer gardener) We just purchased a house with a huge fenced garden with raised beds and I have been having fun growing my veggies this summer. I wanted to build a greenhouse I could use to get my seeds started in spring without them getting damaged by all the excessive rain we get in the Pac NW.

can I use this model to start planting veggies/ flowers in Feb and March for next season or can I use to grow veggies year round?

[donedirtcheap]

This would be great placed on top of a preexisting raised bed. Or I could tack together some low pallet walls and use this as the roof. Thanks for the idea.

[ChalmersAbrams]

I love this idea. It's perfect for many of my clients who live in urban or suburban settings and can't build a large greenhouse. I'm going to link to this post in my newsletter, thanks for sharing!

Where am I to get "Visquene or Plastic Sheeting?"

Also, is there a way to seal it air tight?
I want to make a carbon-dioxide hiyperberic chamber, as is it was in the pre-flood era (Yeah, I'm a Christian, and proud of it!)

http://www.genesispark.com/genpark/exper/exper.htm

If any one reads this, you'll know why I want to build one. Think about it! A tomato tree, that can produce over 13,000 tomatoes in it life-span!

To bad I can't have a warehouse sized one. *sigh*

(I hope I did the URL link rightATMOSPHERIC EXPERIMENTS)

[TKDWILSON]

If that was possible to do, I imagine someone would already have done it.  Plus, you make that thing airtight, the plants burn up all the carbon dioxide and die.  There is a reason animals are there.  Plus, tomatoes do not grow on trees.

[Darth_Reese]

I know tomatoes do not grow on trees, but what do you call something that grows 30 ft high?! Have any of you even looked at the URL? I admit it, it does not sound believable. Once I've done more research and money I am going to try this.

[ToniB]

Darth Reese: I looked at it. Fun and interesting site... and yes, I would call a 30 foot tall tomato plant a tree. Though technically incorrect, I knew what you meant, and am less picayune about such things.

Pondplantgirl... Loved the instructable. Thank you

[Pizzapie500]

Sorry for a very late reply, but first of all, tomatoes don't grow on trees... (They grow like peppers)

[lahaina2wins]

First of all, you need a high altitude ice canopy.  Make sure no comets are in the area, or it could cause the fountains of the deep to burst forth.  Second, put a stop to all the silly global warming interventions that are ultimately designed to decrease CO2 contributions.  Finally, make sure no reptiles are in your hyperbaric CO2 chamber, as the associated increase in O2 will allow them to reach dinosauric size and strength, and they might turn against (you) their maker, just the way the rest of us have turned against our maker ;)

[lasersage]

I may be wrong but from what I remember:
plants can only use carbon dioxide whilst photosynthesising, during the night they use oxygen and release carbon dioxide. On this basis some old trees which don't do so much growing are supposedly releasing more carbon dioxide at night than they use in the day!
Anyway trees aside, if I'm right (and I think I am even though I didn't love biology at school), then you would not only need a carbon dioxide tent but also a constant supply of light, and you can't just seal in the carbon dioxide, the plants need a fresh supply as they will keep converting it into oxygen.

I don't feel any need to discuss religion in reference to this topic.

[Saint_Awesome]

Better be careful, the Lord may not take kindly to you manipulating His creations in such a scientific manner. Recall that even in Sodom there existed a high level of technology and material comfort abounded, only to allow morality to be corrupted by sin. Remember, the Lord drowned the inhabitants of earth for a REASON! If He meant for this technology to be saved, he'd have told Noah to take it with him.

[Innie]

Hi, The Lord gave us our brain with which to survive and has nothing against having a greenhouse, no matter how technologically advanced it may be. There is nothing sinful in it. It is only when man uses technology to go against God's will that he sins. I am Christian and know that much!

[radiochemist]

ok person if you think the bible says that growing plants in green houses is sinful then I would hate to think of what else you think is sinful that you're missing out on. go enjoy life, stop living in fear and start living!

Please, Don't feed the trolls. lol

[Grey_Wolfe]

I am not certain how you have come by the idea that plants are not 'alive' in the usual sense.

alive [əˈlaɪv]adj (postpositive)

1. (of people, animals, plants, etc.) living; having life

They are not animate, but they are most certainly alive.

Also, if we are going to play the bible card, one might consider that Adam and Eve were permitted to eat of all the fruit in the garden save that of one tree. It doesn't say that they tore up the plants and ate them whole. Eating fruit doesn't kill the plant.

I won't question your faith, but let's not be piecemeal with the facts. A wound is not the same as death. Nothing biblical lends credence to the idea that plants are not alive.

We might also consider that a man (however devinely inspired) wrote Genesis, not God. Thus the details can at best be assumed only to have the accuracy expected of a historian. So no one is saying God lies.

Free will leads to the possiblity of inaccuracies, even if they are slight, as well as the option to add personal bias to the text. Especially when we consider how many revisions have been made to the original texts. Many different motives have had their effect on our current bible, we should do well to focus on the faith and not literal descriptions. After all, a good number of the terms and verses were incorrectly translated (possibly with intent).

Assuming even reasonable accuracy in our current bible (and I believe at least that much is true), God has given up all right or ability to control the actions of any human. That is your gift from your God, have faith in it and quite trying to tell people they are wrong for chosing a different route.

In conclusion: believe what you wish, let others do the same and last, but certainly not least, BE NICE. (It's in the ToS, lol.)

[Innie]

Hi, Why are you dragging your foolish views into this discussion. People like you make religion look bad because you say things that are ridiculous. I am a Christian too, and growing plants in a greenhouse is obviously not sinful. Anyway, Adam and Eve sinned because they disobeyed God, and for no other reason.

[nave]

how do you know plants don't have souls?

[hcold]

The Bible, sir, has no basis in reality. Please leave these people to their science.

[shmacky26]

And just exactly how do you know this?

[Saint_Awesome]

Same way OP knew HIS 'pre-flood' information.

[shmacky26]

You're just silly. Technology 10,000 years ago? I don't think so. You're just getting caught up in middle eastern fables. Haven't you noticed that most religions have come out of the middle east? And what about dinosaurs? What was their sin? Do we have to put religion as the cause of every natural disaster?

[lukethedog]

This is a great instructable. I liked the YouTube video. But, please tell me how the religious wacko's found their way into this thread?

[lahaina2wins]

The whole idea is that "young earth creationists" believe in this "ice canopy" or something similar that involves higher atmospheric pressures allowing animals to have better oxygen saturation.  This would allow for reptiles to grow huge and for people to live 500-900 years.  It also neatly allows for global deluge theories (canopy collapses), catastrophic geological explanations, and short discussions on extinction and fossilization.  Best of all, it reduces the geologic time period to one that seems more reasonable to literal Bible believers, thus eliminating any need to ever question the book's integrity.
Hope this answer was enlightening...

[Darth_Reese]

Hmmm. Good question.

[PondPlantGirl]

Luke - I haven't a clue! I would much rather talk about plants and better NATURAL ways to grow them. I lives are SO filled with chemicals which produce tons of health problems. I have a friend who lives across the street from an orchard. Her name is Robin. She decided to no longer breed koi, because when the orchard was sprayed with insecticide all of her fish would go belly up.

[phoenixjen]

If people don't respond to them they usually stop posting. So it really is the posters that perpetuate the problem by replying to their posts.

[lukethedog]

Hello - Gee thanks for your fantastic insight ! Five months later and you come up with such sage advice.

[PondPlantGirl]

The best place to purchase visquene is at Lowes. They seem to have the best price. You can purchase it in small amounts to very large amounts. It all depends on your needs. The plastic can also be purchased at Home Depot and even online at eBay. The easiest way to make it more air-tight would be to caulk the holes and attach the sheeting to the base of the structure. I choose not to make mine air-tight so that a strong wind will not blow the structure down. Hope this helps! Please remember to tell your friends about me!

Hi all,   "Vizqueen" [sp?] is a brand name for the FIRST plastic film VAPOR BARRIER for use beneath Concrete floor slabs.  Before that tar paper ["builder's felt"] was used, with joints being sealed using hot melt Tar.

The Vizqueen made a much easier installation, and less chance for error and thus ground water vapor getting up into and through the Concrete slab and into the building.

Vizqueen first became available [I think] in the late 60s or early 70s, and since then there have been many competing brands to become available.

Plastic vapor barrier usually comes in long rolls, and one cuts off what is needed.  Due to multiple "fold-overs" the box in which the roll comes is only about 4 or 5 feet long.  One or the other brand of vapor barrier can be obtained at most Home Improvement stores [Lowes, Home Depot, Sutherland's, etc.], many of the local hardware supply stores, and most lumber yards.

[kittscarmen]

Tis looks like a terrific idea. It is pretty cold in the northeast today, but I will be thinking about this as a way to start my veggies early next spring. Thanks

[PondPlantGirl]

Hey! You are welcome. Cold frames (mini greenhouses) are great for getting that jump start to the spring garden. However, I am working on a design to have a veggie garden year round. Thanks for the nice comment! You can check out more of my videos at www.pondplantgirl.com and at www.youtube.com/user/pondplantgirl :-)

[Darth_Reese]

Can't watch the video, dial-up

[PondPlantGirl]

That's sad, Darth. E-mail me and I will see about sending you a DVD. ;-) [e-mail]

[anon_inkpen]

Awesome instructable! FYI, you can usually get free 3.5 mil plastic from mattress stores - after a delivery, they throw the bags out. a king size mattress bag is 70x80 inches.

[greenjedi]

Haha, I just got some from the dumpster about 2 days ago. And now I read this. I guess great minds think alike ;)
