How to Build a Hoophouse in 136 Easy Steps

In 2008 I decided I wanted to start a CSA. To get an idea of what I could raise veggie-wise I grew a giant two acre garden and sold the produce at a local farmers market. That year I planted tomatoes exactly the same way I had always planted tomatoes…out in the garden with everything else. My tomatoes that year did pretty well and I got lots of nice compliments on them.

In 2009 I launched the CSA and once again planted tomatoes out in the garden. That year the plants met with total disaster. First they wilted, then the leaves turned black, then the unripe tomatoes turned black and the whole mess died. I felt terrible. Here I was with a brand new CSA and whole slew of rotten tomatoes. And everyone knows that tomatoes are one of the crown jewels of a CSA box.

As soon as I noticed a problem I frantically started doing research on what could’ve caused the collapse. I learned that tomato blight was the culprit. It had blown into my county and obliterated many a tomato crop. The blight is a type of fungus that comes in, attacks plants, spreads, kills and generally decimates.

After that whole debacle, I decided to do everything in my power to not get the blight again. I toured some other local CSA farms and found that it was popular to plant most tomatoes in a hoophouse. A hoophouse is an unheated greenhouse made of big hoops, hence the name. Plants are grown directly in the ground inside the structure which is covered in a giant sheet of heavy duty plastic. The shelter a hoophouse provides keeps the tomato plants safe from wind and rain which are the two main vehicles for blight.

When I learned this I was kinda irritated that tomatoes needed so much fussing with. Here was a vegetable that in most years grows profussly and happily right out in the field with really very little care. Some years the plants will die of blight but most other years they will be fine. Anyway, I decided to not take the chance and put up one of these nifty hoophouses.

Like most things, this endeavor turned out to be easier said than done. The construction took me three solid weeks and I had lots of help from my husband, dad, father-in-law and uncle in addition to a whole bunch of folks that came to help put up the plastic. I’d probably still be working on it if I hadn’t had any help. Here are the steps in case you want to share in my trials and tribulations. Or if you are planning on building one yourself, these steps may give you some insight on what to expect.

1. Figure out where you want to put a hoophouse
2. Learn that you can’t just toss one up anywhere, the ground has to be flat or made to be flat, realize you have no interest in hiring a backhoe
3. Select a new site that’s naturally flat
4. Figure out how big of a structure you can fit on your designated site
5. Select a hoophouse that has a style you like and a size that suits your site
6. Agonize over it a bit, finally realize that you have to shit or get off the pot and pick one already
