Hi Daniel,
Thank you for taking the time to share your feedback with us!
We were surprised how well engineered it is. It made the assembly simple. I can't wait to start my grow.
Best of luck with your grow – happy gardening! 🌱🏡
Love so far, my husband put it together pretty easily, especially with the YouTube videos, quality is great, sturdy, price appropriate. Good experience with the company also so far. However be aware this kit is not for an inexperienced person to build, you need tools and a clue or it might not go so well. But that is not a company issue! We are happy.
Hi Lynn
Glad you're enjoying your Greenhouse! If you ever have questions or need assistance, we're here. Happy gardening!
Overall I have been very happy with this greenhouse. It has not yet been through an Alaskan winter, so I'll reserve complete judgement on its for now. From the sturdiness of it I expect it will do just fine this winter.
But for two minor issues I would have rated this kit 5-star. Delivery of the kit was very timely. Putting it together went relatively smoothly. Only two points in the assembly caused minor inconvenience or confusion:
(1) During the installation of the covering panels, the shortness of the screws (#53) made sliding the side panels into the brackets impossible. I had to buy screws locally that were a 1/2 inch longer and then the installation went quickly.
(2) The kit included door and window linings (Y1-Y12) which are not referenced anywhere in the instructions, nor do they fit any of the doors or windows -- hinge cutouts are the wrong size and in the wrong locations. Very confusing, but have no apparent affect on the greenhouse function.
Thanks for a great product.
Thanks for your feedback! 😊 Overall, we're glad to hear you're happy with it. While we're confident it will handle the Alaskan winter, we appreciate your patience in dealing with a few minor hiccups during assembly. 🏡❄️ Happy gardening! 🌱🌼
