    Love this!

    We got the Sigma 32 as a family project, to experiment with gardening, get the kdis outdoors, and have some homegrown fresh produce. Our kids are obsessed! We're growing so much that we started pickling a bunch of veggies because we just can't keep up. This is such a wonderful investment and I bet it'll still be in excellent condition when my kids are grown.

    First greenhouse

    This is our first greenhouse and we're already growing tomatoes, carrots, cucumbers, bell peppers, spinach, and so much more. No bugs! It will easily withstand our midwestern winters and I look forward to being able to harvest my plants while it's snowing outside.

    Get the biggest size you can

    We did and we already are wanting more room because we're out there every single day. You'll have so much fun alone or with your family. Its strong, well designed, and your plants will grow twice as fast. There are absolutely no downsides.
