We finally got this put together this Fall. it is a Grow Smart 13 X 13 twin wall polycarbonate. It came in 6 boxes and in 1152 pieces. The greenhouse itself is nice but it was so hard to put together. The directions were only pictures. The floor is just mud right now hence the cardboard on the floor. I plan to improve the floor but I have not decided how yet. I am looking forward to Spring when I can use it more. I have some potted plants in there right now for the winter.
