The Bio Star 1500 Cold Frame by Juwel makes getting an early start on the growing season easy. The unit is simple to set up and spacious enough for plenty of plants.
A true example of the finest in European design, the unit features weather resistant 8mm polycarbonate double skin panes which are UV resistant and guaranteed against yellowing for 10 years. Three large windows allow you to regulate airflow, and the "no drip" coating prevents condensation on plants.

The worst instructions ever - impossible to put together!
Stephen Gray | 5/27/2021
Hi Stephen,
I’m sorry that you’ve had difficulty assembling the Biostar 1500. We do have a YouTube video that addresses a few of the key assembly issue that end users run into that may be helpful, it can be found here. Additionally, I am also attaching a few images to help in the placement of the sides of the coldframe (see documents section below for PDF) – if the side panels are placed with the aluminum extrusions in the wrong direction, it can cause issues with assembly. These are being noted in the new version of the assembly instructions being printed currently. Please also feel free to reach out if you have any additional questions or need assistance, we are here to help!

Do they make screen covers for summer growing and to keep out insects? I thought I had seen them available?
Erin Millus | 2/22/2021
Hi Erin,
Thank you for your question. The Biostar 1500 does not have a screen option available. There are a few models (Biostar 1000 and the Year-Round Cold Frame) that do include a screen. It is hard to have a screen along with the auto opener.
Thanks, Customer Support
Do you sell spare parts i.e. the green plastic lifts for the Cold Frame covers? What is the cost and availability? Thanks
Jack Giebler | 2/22/2021
Hi Jack,
Yes, we do carry parts for all the cold frames and we do have the lid clips you are referring to. They are $1.50 each plus USPS shipping.
Please give us a call at 512-407-8500 to place an order.
Thanks, Customer Support
Can the biostar 1500 be used with raised beds?
Gardener Chax | 6/5/2019
Hi there
Yes, you can use any of our cold frames, including the Biostar 1500 on a raised bed. The Biostar 1500 comes with ground stakes that can be pushed into the soil in a raised bed.
Conversely, we also do have some clips that catch on the aluminum frame if you have a raised bed with the same dimensions and wish to attach it to the frame.
The main concern would be to ensure it would fit the area of the raised bed you are intending to use.
Thanks, Customer Support
