Thanks, Cinda! I've been wanting one for so long, but have limited space, so even the smallest kits were just a little too big for my space. After watching lots of You Tube videos and gathering info on this site, I decided to build it myself. This is my first attempt at building anything, but I learned a lot and made mistakes. Overall, I am happy with it, but not sure about the heating in the winter. We can go to 0 here in NY, and I wanted to keep it at around 35-40 in order to overwinter my temperate bonsai. The typical greenhouse heaters are overkill for the size (6 X 3), and the personal space heaters seem too small. I will keep looking and maybe someone on this forum can make a suggestion. Good luck with your plants!
