Description
Supremely insulated with 8 mm twin-wall polycarbonate panels, the BioStar Cold Frame Mini Greenhouse from Juwel is just as robust as a walk-in structure and retains heat better than glass. Three roof windows open independently to optimize airflow and humidity, and an automatic opener affixed to one roof panel will raise and lower as the temperature fluctuates so plants don't overheat. A drip-resistant coating prevents beads of moisture from falling on vegetation even when humidity levels climb.

We already owned 2 of the Biostar 1000 and ordered the 1500 based on the quality and performance of those. Unfortunately it arrived in a box that had clearly broken open and several critical components were missing, presumably lost when the box was damaged and before someone used Amazon tape to patch the box back together again. Draw your own conclusions. But here is the important information if you are considering purchasing one of these or its smaller Biostar 1000 sibling: 1. The quality of the design, polycarbonate sheeting and construction are excellent, sharing many of the same construction techniques used on the smaller Biostar 1000 sibling. 2. The polycarnobate sheeting is 8 mm thick, providing a substantially higher level of insulation and strength than the 4 mm polycarbonate used by many competing cold frames. It is also coated for UV protection on one side of every sheet to provide extended product life time. 3. Assembly is easy and quick (20 to 30 mins max.) if you assemble on a flat surface, like a patio or driveway. The instructions are also clear, in English and with pictures to help you. 4. The cold frame is extremely easy to move, being light and made lighter by the easy removal of two of the top panels (no tools required). However it is also large so do not recommend trying to move it long distances on a windy day. 5. The cold frame is very easy to disassemble and store flat packed, taking up relatively little room in the shed, garage or basement. It also reassembles just fine over multiple years without issues. This is one of the reasons we decided to buy a second and now a third Biostar cold frame. 6. Based on our Biostar 1000s it is highly likely the 1500 will also be able to withstand the weight of up to a foot of snow for short periods of time. Basically until you sweep it off in the morning or evening. This is another of the reasons we decided to spend this kind of money on a cold frame. We live in the Buffalo, NY snow belt and an ability to survive intact a serious snow load is a prime requisite for any cold frame or greenhouse here. 7. The size is great for typical dimension raised beds and the height for growth provided is better than provided by most cold frames. 8. The 1500 comes with an automated lid opener. Something the Biostar 1000 does not. This prevents unexpectedly sunny weather from literally cooking everything inside the cold frame. Something we've had happen with the 1000 where the provided lid handles automatically lock the lid down and provide no safe option for leaving the lid locked slightly open without sliding the polycarbonate panels towards the center to open gaps at either end of the lid. This approach does work to a degree and enough for most days in the spring but to our cost we have found it isn't enough on some days. So, if you are thinking of choosing between the Biostar 1500 and the Biostar our recommendation would be to spend the extra $s and buy the latter as long as it isn't too large for where you intend to use it. Despite our unfortunate experience from the broken open packaging of the first Biostar 1500 we attempted to buy we will move ahead with purchase of another one once we've received our refund from Amazon. This is a true four season-capable cold frame. We have no affiliation with Amazon or the manufacturer of this product. No form of compensation has been received (or requested) for the provision of this review which is provided in good faith.

Background: I have 4 cold frames from 3 different manufacturers. All of them use the same Univent automatic opener as this Exaco cold frame. So I am very familiar with both cold frames and with this opener. The good: Fast shipping. It arrived 2 days early. The box had a few big gouges in it but nothing was damaged. I now [finally] have it assembled except for the opener, and that will be easy. I like the large footprint and think this will make a great gift for my mom. HOWEVER... The way the side/front/back panels go together is beyond clumsy. The pictures in the assembly instructions are indistinct and misleading. We got it assembled, scratching our heads the whole time, then ended up having to move every top bracket to a different location before it finally came together. It is decidedly a 2-person job. They really need to redesign the way the panels attach to each other. They noted that the blue protective plastic denoted the UV-resistant-coated outside of each panel. But they apparently sent us either 2 left panels or 2 right panels, because there was no way to put it together and have the blue covered sides facing out. Then there were the missing opener parts. Both of the little backing plates for mounting the opener were missing. These openers come with 2 cotter pins: one huge one that I've never used, and one small one that you actually need. The small one was missing. The only reason this didn't stop me in my tracks is that I had those parts on hand from a previous opener that I retired a while back. Extremely minor nit: The picture in the Amazon listing shows the opener mounted to one of the end lids. But that's not happening, because the holes in the front panel are pre-drilled and they're in the center. I'm actually happy about that, because I wanted the center lid to be the one that automatically opens. You could, of course, seal up the pre-drilled holes and drill new ones if you really wanted to mount the opener to one of the two end lids. Bottom line: Four stars for the finished product; I took away one star for the poor assembly design and missing parts. I think that's more than fair. If you can figure out the bizarre assembly AND they send you all the parts, this is a fine cold frame. But I don't think I'd buy another one, because I don't want to go through the assembly again. Before I put it together I told my mom that we could take it apart and store it flat during the summer, then reassemble it each winter, but no way am I going to do that lol. Sorry mom.

I’ve purchased four different cold frames from Amazon. This is the only one that held up undamaged for more than one season. The wooden ones blew over repeatedly and came apart at the seams. The Jewel is well constructed and my first one is now on its third year in our garden. I really like the automatic opener which works like a charm. This brand (and all of the other cold frames I’ve bought) blows over easily in our windy area so I put a brick or heavy rock on each corner where it does not interfere with the automatic opener. I place a garden stake in back of it to keep it in place better and prevent blow over. I use them in my raised beds from November to April here in NY. The assembly instructions are not sufficiently clear when it comes to the top corners so assembling the first one was challenging. We learned how to do it and had no problem assembling the second and third ones we bought a year later. This frame is more expensive but will last much longer than any other cold frame on Amazon.

Difficult to assemble due to the poor instructions but dooable... It is very flimsy not as ridged as expected, opening and closing the 3 c overs l would not expect it to withstand more than a slight breeze. Not expecting it to last more than a couple of seasons.

Have not tried to engage the automatic opener until now because it was not yet cold frame season. It doesn't work at all. I watched the video and repeatedly checked that it was assembled correctly. The opener doesn't work. Just buy the cheaper model without this unreliable piece.
