How to Build a Greenhouse in 1 Hour

This is an easy way to cover your pond or garden. 


BUILD AN EASY GREENHOUSE in less than 1 hour

The basic plan includes: 
2 - ½ inch 10’ long PVC pipes
4 - 1/4 inch or smaller thick, 12 inch long stakes
4 mil thick or 6 mil thick plastic sheeting
scissors
zip ties

The greenhouse featured was a set of 4 frames attached to each other.

Step 1: Pound stakes into the ground

Pound at least 4 stakes about 6 inches deep into the ground for each corner of your greenhouse.  You can use rebar or even tree limbs sharpened to a point (tent stakes will not work because of its shape).

Step 2: Bend PVC pipe over your garden

Slide one end of the PVC pipe over one stake and bend over your garden. Slide the other end of the pipe over the stake on the other side of your garden. Repeat for the other corner.  If your garden is large, then you will need to add additional stakes and pipe.  This is what I did for the long water hyacinth troth that I built - the feature pic. 

Step 3: Lay plastic sheeting over frame

Lay plastic sheeting over the frame.  Carefully poke holes with a pair of scissors and attach with zip ties.  Allow for a flap opening on one side to allow for room to tend to your garden.  That’s it!  It’s amazing how warm this simple greenhouse will keep your garden throughout the wintertime.

reptile cage heat rocks on extension cord? i would think it would give off a mild heat but not enough to hurt the plant or burn anything. they also have extension cords with ends that have multiple plugs. hope this suggestion helps. also they look like regular rocks so not a big eyesore accept for the extension cord.
I could never figure out how my brother and sister-in-law grew such a hugh amout of tomatoes, and they are still growing. Well I finally asked them, here what they said. They bury gutter heat tape under the soil and leave it on. They get an early start, and a late finsh. I live in Palmer, Alaska and it's now Sept 24th and they are still growing tomatoes. you need to buy gutter heat tape only, you can get it at lowe's or home depot and it comes in different lengths. so I'm going to do it. You can bury it below the dirt. They didn't just bury it in one length. they kind of made a s shape out of it under the dirt. they have raised boxes in their greenhouse. and they didn't do that with the other box they have in their greenhouse, for growing cucumbers. It sits on the floor and they had a bad year for their cucumbers. So next year they will also raise the box and put in gutter heat tape.

Working on rebuilding a similar greenhouse for my mother, with the exception of using clear corrugated PVC panels. Double pipe arch with four-way connectors and the panels overlapped and screwed down to the pipes. Should be fairly sturdy, with less replacement required than the sheet plastic.

We bought 6 mil 100'X20' polyester film, clear. my husband says it's called clear painter's plastic.

I found this on Amazon, similar to what we bought, what we bought cost $100.00.

I made one similar to this. I used 3 JUMBO sized clear plastic table cloths from the dollar store.

Is it the one that you use for painting?
Looks good. But does it keep them any warmer in the winter??

So far my water hyacinth are still growing like springtime and the night time temps have been around 38 degrees.  It will definately keep off the frost.  This is the 4th one I have made and I like this design the best, because of how easy it is to assemble.  I have a new greenhouse design that describes how to attach the same kind of PVC pipe frame up against your house and using the dryer vent for additonal heat.  Being up against the house also provides some protection against the cold.   But, I'm still brain storming on cost effective ways to heat greenhouses in cold climates!

GARDEN BLESSINGS!

Composting gives off a great amount of heat.
