Make
your own greenhouse for $50
By Kelly Averill Savino
Am I proud of myself or what? I
wanted an early start on my lettuce, peas and spinach, a frost-proof
place to get my tomatoes in early and a way to extend my harvest
into the late fall and even winter. I had always managed to put
together a cold frame out of trash-picked storm windows and scrap
lumber, but I fantasized about a simple hoop house.
So here it is. It took me just
a couple of afternoons; 10 cinder blocks I scrounged somewhere;
10 pieces of 10-foot PVC (1-inch); a scrap of 1-1/4” PVC;
and assorted “x” and “t” connectors (my
only real expense!).
The basic instructions
I buried the blocks and hammered a two-foot length of 1-¼”
PVC into each one, right into the dirt to ground level. To make
the 20-foot arched sections, I just bent the PVC and poked one
end into each 1-1/4” sleeve in the ground. They stood there
like an enormous rib cage.
I happened to have come by a roll
of heavy duty plastic from an art installation at the local college,
and it was 12 feet wide, so I made my greenhouse 12 feet long.
I stapled and then sandwiched one end of the plastic between two
long strips of 1”x2”s, then rolled it up like a window
shade. I rolled it over the top and anchored the other end to
boards as well.
When it came time to cover the
ends and find some way to attach the plastic to the PVC, I tried
cutting a bit of leftover one-inch pipe into two-inch lengths
and then cut up the side of each one with a hacksaw so it could
open like a C-shaped clamp. I stretched these open (hard on the
fingers) and clipped them around the plastic I had wrapped around
the arches. Too long and they are too hard to open … too
short and they pop off in a wind storm.

Finishing it out
It's not gorgeous, but I have spinach already, and last weekend
we had hail and snow -- yes, in April (welcome to Ohio!). Anyway,
I built a simple “H” shape out of scrap lumber and
buried the legs under the front end arch of my hoop house. Then
I cobbed the old wooden screen door right off the back of my house,
cut it down by 16 inches with a circular saw and reattached the
screen. My kids were really amused. They told on me when their
daddy got home from work. "Mommy took the screen door right
off the house!" He just sighed and went to Home Depot to
buy another one. He's a good sport.
So we're all pretty happy. My kids
are impressed. After I took these pictures I did one more thing:
I drove wooden stakes along the side walls, screwed eyes (like
from hook and eyes) into the top of each one and then ran a thin
white nylon cord across the top of the hoop house in the gap between
each "rib.” Then I used two small bungee cords to attach
the rope to the stakes, one on either side. When the wind really
blows, the hoop house puffs out like it's going to sail to the
neighbor's. The tie-downs seem to keep it a bit more secure and
not so flappy when it's windy.
It was really amazing how quickly
a patch of wintered-over garden became a dwelling of sorts. It
must be the same thrill Neanderthal women got from arching those
big mammoth tusks, pulling skins over them and having a nice warm
house. I built a few cold frames inside my hoop house with bricks
I pulled out of the dumpster at the Unitarian Universalist church
(where they're remodeling) and topped the bricks with old storm
windows. I made a similar "H" out of boards for the
back of the hoop house and made kind of a window by cutting a
flap of plastic out that I can open and close to ventilate.
This is my kind of project. It
cost almost nothing, I could do it by myself in a weekend, and
I am going to have the earliest tomatoes in this part of Ohio!
