Great garden addition!
Greenthumb2026 · 5 months ago
The Aggie Cold Frame Box did not disappoint! The assembly did not take long, and all of the parts fit well together. I am still figuring out how to best use the box with its temperature lid adjustment. It really opens automatically when the inside of the box gets above 70 degrees! It is a beautiful addition to my patio garden.

Great garden addition!
gardengirl2026 · 5 months ago
What a find! This cold planter box is a wonderful addition to my garden. It will be an asset in starting my vegetable garden as well as keeping vegetables during the late fall and winter months. The automatic lid lift is especially wonderful. It does open when the temperature gets above 72 degrees!

Beautiful, functional cold frame
STL Gardner · 6 months ago
I’m happy with the overall quality of this Aggie’s Cold Frame greenhouse. It is a unique, beautiful, and genuinely functional product, and I think the price is fair for what you get.
The best feature is the automatic ventilation. It works beautifully and saves me so much worry about my seedlings overheating during the day. That alone makes the cold frame much easier to use than a basic covered box.
One thing I was surprised by: after purchase, I received manufacturer guidance explaining that the wood needs ongoing protective treatment, and Backyard Discovery’s own care article says resealing is required for warranty coverage. I read the listing carefully before ordering, and I do not think this maintenance requirement was made clear enough upfront. I don’t mind caring for wood products, but buyers should know that this is not a completely maintenance-free cold frame.
My main complaint is the lid support system. The wind chain is not very useful in my case. The wood is on the softer side, and the chain is only held by a tiny screw, so I don’t feel it adds much security. When I’m taking plants in and out, I really wish the lid could stay open more reliably. For this price, I think a proper lid stay should be included. It would make the whole system feel complete.
I ended up ordering and installing my own lid stays. Because of the automatic ventilation arm, not every type of lid stay will work, so it took some research to find a compatible solution. After installing them, I love my Aggie’s Cold Frame even more.
Overall, I do recommend it. It is attractive, practical, and very helpful for seedlings, especially because of the automatic ventilation. Just be aware that the wood requires yearly maintenance, and you can want to add your own lid stays for a better everyday experience.
✔ Yes, I recommend this product.

Great gardening box
Docinthebox · 6 months ago
I got my cold box at the beginning of March and put it together during some nicer weather. It was pretty straightforward but the planks across the bottom that support the dirt were a little too long so it angles out a bit toward the bottom. The track for the temp activated hinge is a little too short and it went off track and got stuck open a couple of times so I had to move the track. Other than those 2 issues, it’s great! I started a bunch of lettuce and onions from seeds and they are thriving. We have a short growing season here in SD and a lot of hail and deer. This beauty solves all of those issues and keeps my garden safe from those things. The temperature activated arm works great and is very unique. Im planning to buy a second one to expand my garden and hopefully grow herbs year round 🤞🏻
✔ Yes, I recommend this product.

Perfect for our home
RLO2025 · 9 months ago
Like many people, we suffer from deer (no longer just a problem for us rural folks…). I had all but given up on outdoor plants and/or a garden when my wife found this gem on your website.
Assembly was easy and the quality of the product was incredible! Delivery was fast, as well.
Almost everyone who visits us (friends, repairmen and even our garbage man!) have taken a picture and say they plan to order one.
