Landscaper - Would like to build a small greenhouse for annuals

[BrendonTW]

I would like to construct a small green house for raising only annuals in. I probably only need 200-400 square feet. Especially if I can build two levels for the plants.

Just looking for some advice. I know nothing about greenhouses or nursery raising. I can think of climate control and irrigation as essentials. What else am I looking at in getting this thing going? Would you recommend anything specific for the walls/ceiling of the thing? Plastic? Canvas? I really have no idea where to start.

Did you build a greenhouse? I just bought a kit from Oregon Valley Greenhouses.

I ran some numbers a few years back when I was considering growing some annuals. I couldn't see any profit in growing on a small scale like you are talking. I guess it could be different in other areas depending on what prices local growers are offering. But if you are determined my advice would be to look for used greenhouses at a bargain. That way you have less to lose.

Growers Supply has EVERYTHING that you need to build your own greenhouse. They have greenhouse kits in case you decide not to build your own.

Here are some plans for building a greenhouse, greenhouse benches, and a propagating frame.
