    Finally done!

    Awesome kit. No complaints. As someone who worked in the sheet metal world, I was impressed with the tolerances held especially the hole to hole alignment. The only tricky part was the end seals.

    Sungrow 20

    The greenhouse and instructions overall were very good. Holes lined up very well and turned out good. I poured a concrete pad for the floor hoping this will help in energy storage for cold days. I also used a double 2 x 6 treated plate that bolted to the concrete and therefore raised the house 3 more inches. The bolt packs were short on the long bolts for the poly so I had to make a quick trip to the hardware store. That is the one thing I wish would improve, the bolts and nuts are a lesser quality than the structure. The metal is soft and were partially rusted right out of the boxes. The softer metal allows for a very easy cross thread especially if you gently try to use a cordless impact or drill to run a bolt through the layers.

    window on top of the door

    It is a good product. I have one observation for the windows on top of the doors: I designed a net for the opening so the unwanted bugs and animals cannot access the opening.

    High Quality

    Very good quality. A little time consuming to put together but very happy with the finished product.

    The one thing that would be an improvement is a screen door and window option. I plan on making my own.

    We like it

    We bought this Sungrow 20 in winter of 2022/23. My wife and I assembled and erected it together in about a total of about 56 hours. We pre-assembled the components in my shop, then, in January of 2023, we took the parts out and put it all together.

    The greenhouse came well packaged with a comprehensive booklet that included a parts manual and assembly instructions. Using that booklet and the assembly videos together are essential for an easy assembly. If you refer to them both, and often, it is really pretty easy to set it up. Make sure that your base is level and square, a good start makes it a breeze to erect.

    There are several rolls of clear tape to seal the polycarbonate ends. Do yourself a favour and buy a few tubes of clear caulking to use instead of the tape. Tape degrades. You could use the caulking as an adhesive to better attach some of the rubber sealing strips, especially around skylights. I would also suggest that the gaps between the polycarbonate and the hold down bands be caulked for better leak proofing. There are some leaks when there's heavy rain, but, for us, it really does not matter, and the plants don't mind a little extra moisture.

    It gets pretty hot in there during high summer, even with the doors, windows, and roof vents open. We put a 12 volt automotive cooling fan in one doorway and powered it directly with a 100Watt solar panel. The brighter the sunshine, the faster the fan runs. If a slower fan speed is wanted, a bit of rag over a corner…
