After a rainy summer like last year, I was able to get a good harvest of tomatoes and peppers in the greenhouse, while my outdoor plants mostly produced rotten fruits.
We overwinter our tropical houseplants that generally stay outside during the spring, summer and fall months. We have lime and lemon trees, dwart palms, as well as we overwinter all of our homegrown herbs in the greenhouse.
Even in minus outside temperatures, on a sunny day the inside of the greenhouse is toasty warm. Last years production maximized my yield and allowed me to automate my watering protocol.
