This cold frame exceeded expectations. Assembly of the frame itself was very straight forward. Mounting the automatic opener was a bit of a challenge for this mechanically challenged gardener. But, a fourth and fifth reading of the directions (and a bit of patience) solved the problem. I've been harvesting lettuce, arugula, and baby Pak Choi of very high quality. I am delighted with this purchase. Moreover, I encourage you to offer a larger size that would more closely fit within the confines of a 4' X 8' raised bed. I already have an older and much heavier cold frame that has been a stand-by in my efforts to beat our short growing season. However, as my wife and I get on in years, it is becoming unwieldy. A lighter version of your current design would be ideal and greatly appreciated.
I put together a Juwel Oversized Cold Frame with the Extender Package as well as two automatic hydraulic arms to open the top panels in warm conditions. It was a very high quality product and was straightforward to put together. It has worked perfectly, although I did have to secure it to the ground to keep it from moving around in high winds. That was not particularly difficult to do, although the stakes that came with the product were not sufficient by themselves to adequately secure it.
For the price I expected something a lot more sturdy and nothing fits together very well. I have fairly mild winters so it will do for me but I would not recommend this product for people in colder climates.
I bought the oversized Juwel coldframe in hopes of pushing the growing season further into our colder months. Unfortunately it was backordered until almost Thanksgiving, so it didn't get assembled and ready to go until early spring. I used it to shelter seedlings before they were ready to be planted and also grew beautiful lettuce in it until about August. It is now planted up with winter hardy lettuce varieties and I'm anxious to see how late I can continue to enjoy my homegrown salads. The assembly was fairly easy once I understood the directions. I really like the way it easily disassembles so I can move it to a different section of the garden when needed. When my fenced garden became too full this summer, I moved the coldframe to a bed outside the fence. The lids worked perfectly to keep the browsing deer and rabbits out of my lettuce. Would highly recommend this particular unit to anyone considering the purchase of a coldframe.
I used my cold frames in early spring for starting Brussels sprouts, tomatoes and broccoli. A friend asked me to start some flowers for her too. Wonderful jump start to the season. I used them two ways -- first I planted seeds in pots in the cold frames and the second I planted seeds directly into the ground. Taking the cold frames apart and storing them are very easy. I just ordered two more to start my fall planting!
