I broke this down into many steps to make it easier. This is such a simple project that even a couple of kids can do it with little to no adult supervision.
This whole unit costs less than $25.00, but gives you the room of a $500 greenhouse.
The whole assembly to less than 20 minutes from start to end.
This is my first post, but hopefully with success it will entice me to post more.
Step 1: Collecting the Supplies
Cost (est) Total
A 6 1/2" Schedule 40 PVC Pipe 10' Plain End $1.25 $7.50
B 6 1/2" "T" Connector $0.30 $1.80
C 4 1/2" 90' Elbow $0.25 $1.00
D 0.5 10 Ft. x 25 Ft. Clear 6 Mil Consumer Sheeting $26.20 $13.10
(Enough to make 2 mini greenhouses)
And a cup of coffee or a soda.
(this project will be completed before your coffee can get cold for your soda warm!)
Total cost (minus your drink and taxes) comes to& $23.40
Step 2: Gathering the Tools You Will Need
Tape measure (at least 10 feet long)
Marker of some type (a sharpie works wonders)
Razor knife or scissors (to cut the plastic sheet)
A saw capable of cutting PVC (I used my saw-all, but with kids they could use a hacksaw).
If you're trying to do this alone, like I was, I used a couple of clamps and saw horses to work on.
Step 3: Start Measuring
Step 4: More Measuring
Step 5: And Still More Measuring
This is all the pieces you need (and should have) to make the greenhouse.
Step 6: And the Final Measuring
Step 7: All of the Cut Are Finished
2 pipes 60 inches long
4 pipes 56 inches long
4 pipes 4 inches long
Coffee is still warm…
Now on to assembling…
Step 8: Assembly Time
Start off with one 90' elbow
Next add 4 inch piece
Connect to T connector
Add on 56 inch pipe
Add another T connector
Add on another 56 inch pipe
Add another T connector
At another 4 inch piece
And finally add in another 90° elbow
Make sure elbows are parallel to the ground while T connectors are pointing upward.
Repeat the above steps making sure the elbows are pointed in the other direction.
Now you should have all of the ground frame altogether.
Step 9: Connecting the Sections Together
Step 10: Time to Go Upward
Step 11: Time to Cover It
Then carefully unfold and slide the sheet over the framework. (I was doing this alone and it was windy, so I had to use clamps to hold it in place.)
Depending on the size in length of your greenhouse you have to adjust plastic sheet so one end is close. If you need to, add a small piece to the open end to seal it (don't forget you need to be able to get into it).
Step 12: Keeping the Edges Down
And you're coffee never got cold.
