    Nova is fantastic!

    We were a little concerned about this shipping (living up in Alaska), but these guys had no issue delivering it and we got it set up and working within a week. Everyone was very helpful.

    Really excited

    This greenhouse holds in so much heat, I wouldn't be surprised if I could grow lettuce year round. Really excited to explore the possibilities!
