For over 20 years I've wanted a greenhouse. It's finally the right time to have one but living in Florida it can't be a greenhouse…it must be a shadehouse! We looked at many commercially made greenhouse kits but they're all beyond our means and they have polycarbonate siding which would keep the building too hot, therefore kill my plants unless we installed an evaporative cooler…and they are also expensive.
Lucky for me hubby has an entire workshop of tools and equipment he's collected through our years of rehabbing and flipping houses and he can do pretty much anything with electric and plumbing.
So I designed my own shadehouse! And we built it! It's 12x10 and 8' high at the back, sloping 3" lower in the front to let rain run off. It's made of pressure treated lumber and PT plywood 2' up. The rest is lined with chicken wire to keep the cost down. The roof is polycarbonate sheets. We used 2 sheets white and 3 smoky. The white allows lots of light through but diffused. The smoky also shields my plants from straight sun but allows dappled sun through. My sun loving plants will live under the smoky roof and the shade plants under the white part. Hubby also installed an outdoor ceiling fan to aid with the air circulation which is so important to plants.
I grow mostly orchids and tropical ferns plus other tropical plants so during our 2-3 months of cold weather we will cover the chicken wire sides with plastic. But as you all know, even when it get down to the 30s at night it gets up in the 60s in the daytime. I didn't want to have to be removing the plastic ever morning and re-applying it every evening so we installed two old windows we had on two sides. The door is an old door we also had and we replaced the glass with chicken wire.
And now for the cost. The same sized greenhouses ran from $1000 - $2000, not counting an evaporative cooler, and replacing the sides with fencing material. Our cost, including the ceiling fan, was just over $600 and three whole days of work.
If anyone wants the list of materials I can post it or PM it.
Here are some photos of the building process. We finished building earlier today and moved the plants in it from my plant room. So after I get everything organized in there I'll give you a tour!
