When growing tomatoes in a hoophouse, think about how many plants you would grow on the same amount of space outdoors, divide that by 3, and plant only that number in the hoophouse. This is particularly important for tomatoes because they can get HUGE in a hoophouse. I learned that the hard way my first year with high tunnels. Not only does it make it difficult to work in there, but it also increases disease and pest issues, and they compete with one another for water and nutrients. You can improve your yield per square foot by planting fewer plants. This is particularly so if you don’t prune the plants (which I don’t do – too labor-intensive).
Peppers don’t get as crazy as tomatoes, but they also consume a lot of water and are very shallow-rooted, so again there can be competition if they are crowded.
