Customer ReviewsWrite a review
I am very happy with the decision to buy a Monticello. I was on the fence for months, but this greenhouse fit my budget and allowed me to buy something pretty large. Assembly was a challenge for my family, but the team answered our questions and helped us through a few issues. The auto vent openers have been great, especially in the heat here in Texas this summer. Looking forward to this fall/winter, so we can really leverage the advantages of this baby!
We are very glad that you were able to resolve all issues. Feel free to reach out if you have any further questions!
