Low cost easy do-it-yourself greenhouse

This time of the year many of us think about getting our plants outdoors but in some protective
environment. Last spring I protected my lone Basjoo with a contraption fashioned from
irrigation pipe and fittings. This worked so well, that I made another couple of greenhouses the
same way this year and here is how:

The first one was for shelter of plants on our balcony, which is exposed from underneath and
therefore needed some bottom insulation.

This first picture shows the skeleton of the structure. The fittings used can easily identified
and counted. For the base I covered some cardboard with transparent plastic bags to keep
the draft out.

A different angle showing one of two black garbage bags filled with fibreglass insulation
and some of the fibreglass ready to go into a second bag. All of this insulation will not
be necessary if you place the greenhouse on the ground or on an insulated surface.

And lastly here is the finished product. The (ice cream-) bucket in the back is filled with water, to
absorb some of the sun’s heat and release it in the night. The little white thing in the foreground
is a thermometer, which I will probably hang up somewhere inside once that thing is operational.

The dimensions are: 45” x 34” x 32” high at corners and 44” at gable. The gable is essential,
otherwise rain water will collect and press on the roof. It should be at least ¼ as high as the width
it spans.

So what does this all cost? (I purchased pipes and fittings from an irrigation supply wholesaler)
Two 20 foot lengths of ¾” pipe......$ 7.-
Fittings......................................$15.-
3 ea. sheets 4’ x 5’ bubble wrap*...$18.-
Total without the insulation:.........$40.-

*I use bubble wrap, to get better insulation. Simple plastic would be quite a bit cheaper.

Tools required:
1 pipe cutter or hacksaw
1 pair of scissors
1 roll of transparent packing tape

Here is a second greenhouse to protect my banana/canna combination, once I dig them
out of the mulch

Beside the low cost, this is extremely practical. The pipe sections fit tightly into the fittings and
are quite secure. When not in use it can be easily disassembled and stored away. Try that with
a much more expensive wood frame.

If I missed anything or you have any questions, please ask me either here or by PM
