  • Mostly pleased
Color: Black Size: 8x10FT
This seems like a pretty good greenhouse but we did not receive all the hardware needed, we are missing the screws for the supports for the roof panels. The instructions are not complete or in the right order, the instructions for the vent windows needed to be placed sooner in the instructions we had to take part of the roof apart in order to slide them into place, how to attach the bar to open the vents and the hardware can not be right and the holes drilled by manufacturers is not right but then again the instructions for this part of it are very unclear. My husband will have to figure out a way to fix the problem of opening and closing these vents. Otherwise I think this will be a very good building ... show more

  • I love my greenhouse
Color: Black Size: 6x4FT
Great greenhouse for starting seeds and wintering over annual plants. Took some thought and common sense to assemble. One person can do it. Fits together well with the exception of the door. It doesn't close tightly and allows cold air to enter. I'm using a shim in the door latch to hold it tight. I set the green house on 1x2s so that I could make a small gap to run a cord for a heater. Added a pallet inside (to keep larger plants off the concrete) and a couple of shelving units (for seedlings and smaller plants). The size is perfect for my needs. Really pleased with my purchase. ... show more

  • Great product but be patient during install
Color: Black Size: 6x4FT
The greenhouse arrived on time and as expected. The instructions were a bit tricky to follow at first, but with some patience, I got it assembled. Once put together, it’s surprisingly sturdy and well-structured. I’m really excited to move my orchid collection in—it’s going to be perfect for them!

  • DO NOT PURCHASE
Color: Black Size: 6x4FT
Product is absolutely horrible! Many pieces do not align and were not cut properly 300 for this was just a waste. Putting it together will not only test your patience but everyone else’s around you!! Avoid this product.

  • Buyer beware
Color: Black Size: 6x4FT
I dealt with a few issues regarding this greenhouse, however customer service was more than helpful and ready to make the situation right. This is a good company who are willing to stand behind their product and ready to offer advice.

The greenhouse is a good thing to add to your yard. The thing is it was easy to build the instructions did show it clearly enough. It’s also a small perfect for small yards. It’s sturdy and pretty strong to the wind.
