Good quality and easy to assemble. Perfect way to start my garden.. Missy. Portsmouth, RI. Sat Sep 21 2024

Spring or fall, we’ve got your plants covered. Get your tender seedlings off to a healthy start as early as possible so your plants will be larger and harder. Grow cold-tolerant crops like lettuce, kale, green onions, and radishes well into the winter months. The frame is an extendable cold frame greenhouse that measures 4ft. x 4ft. and stands 36in. high at its peak. Multiple units can be zippered together end-to-end, to create a continuous row of coverage. The zippered windows allow easy access for tending to your plants and controlling temperature and humidity. The powder-coated steel frame will not rust or corrode, and the heavy-duty PVC cover will stand up to heavy wind or inclement weather. Connects directly to any frame it is all raised garden bed. When used in conjunction with a frame it raised beds you can increase your soil temperature even further. Our open-channel raised garden bed boards insulate the soil against temperature loss (protecting the roots), while the cold frame helps control the ambient temperature around the plants (protecting foliage). The applications and benefits of this cold frame are as varied as the plants you can grow inside it. Save money by starting your plants from seeds indoors early in the winter. Use the cold frame to ‘harden off your seedlings, a process used to gradually acclimate your seedlings to colder outdoor temperatures before planting them in the ground. Simply place your seedlings inside the cold frame for increasing periods of time, (starting with a few hours a day) before bringing them back indoors. Over the course of a week (or two) your plants should be acclimated to stay out overnight inside the cold frame. After your first last frost date, you can begin removing the cold frame for extended periods of time. This period of hardening off prevents indoor started seeds from going into shock outdoors and lets them grow stronger and harder. Seedlings that are started only under plant lights or on windowsills will grow lanky and weak from reaching for the sunlight. Having time outdoors will allow them to grow slower and stronger. If you don’t plan to transplant your crop into other areas of your garden, you can plant your seeds or seedlings directly into the ground. Just make sure to follow the transplant and sow guidelines on your seed package. Starting your seeds in the ground before the first last frost date is important for some plants and flowers that require cold temperatures to stratify. Certain biennials like foxgloves can be forced to bloom the first year if they can be sowed as soon as the soil can be worked. The cold frame can help protect the foliage once the seeds begin to germinate. Whatever you are growing, unexpected freak frost periods can happen many weeks after your last expected frost date. You can easily protect your established plants from frost damage with a quick re-installation of the cold frame. Fall is often a letdown for gardeners. The cold frame allows you to continue to plant cold hardy plants for several months (or year-round) while you are winding down and cleaning up the garden for the year. Did you know? Micro-climates allow you to grow plants that are outside of your growing zone or season. A combination of a cold frame, an insulated raised bed, and a protected location may allow you to create a climate many degrees higher than the outside temperature. Try growing plants that don’t typically thrive in your area. Protect plants that don’t generally over-winter well by placing them in the cold frame until spring. Experiment and save money by growing your own vegetables and saving plants that would typically have to be replaced. The frame system of modular raised garden beds, borders, sandboxes, and accessories was designed by our founder, Anthony Topping. As a professional landscape designer who spent many years creating high-end gardens in the Tri-State New York area, he felt there had to be a way to give homeowners the ability to easily create quality landscaping features and gardens for much less than paying a professional.

These were exactly what I needed! I recently started an 8x4 raised bed in my backyard that was getting invaded by multiple animals. I couldn't find an affordable 8x4 cold frame cover, so to work around this, I bought 2 of these 4x4 cold frames, which did the trick. I didn't realize this until after I already put them together, but you can combine the two 4x4 frames into one long 8x4 with the zippers. I didn't read the instructions though & ended up constructing each one separately and then putting them side by side, which still worked for me. The vinyl is a little wrinkly at first, but it smooths out after some time.. Erica. Atlanta, GA. Sun Jul 02 2023

Complete garbage. Wood is thin & cracks as soon as you try assembling. I followed the very basic, pictorial directions and used all included hardware and before the frame was even assembled, the wood on all sides cracked and split where the screws were put in and the whole thing fell apart.

The produce seems fine, the top piece had a crack and I requested a replacement part but haven't received it yet. Update: After putting it together and putting in the shelf I noticed that the threaded peg that attaches to the side for the shelf is missing. It didn't fall out but was never installed by the manufacture. This unit is ok, but if I knew I was going to have these issues I wouldn't have purchased it. It took a phone call to Wayfair to get my replacement top that was cracked in shipping. I had requested a replacement online, never received a confirmation email. I waited a week then submitted another request on the website and no response. I finally called Wayfair and was told they could see both of my requests but they were never processed. The customer service rep was able to get the request processed and my replacement part is on the way. I am not happy with the manufacture of these Greenhouse. I wouldn't purchase it again. I will probably live with the missing piece or see if I can purchase one at my local hardware store. It's easier than trying to get a replacement part from Wayfair. I will be rethinking any future purchases at Wayfair.. Deborah. Tue Jul 23 2024
