This Cold Frame Mini Greenhouse by Juwel® is a great alternative to a permanent greenhouse if space or complexities are a concern. The unusually thick panels are identical to those used in full sized high end greenhouses throughout Europe and the United States. These panels retain heat far better than glass and are even stronger. If it’s an 8-9 month growing season that you care about and you want to clear some yard or patio space for winter, the Bio Star 1500 dismantles in five minutes for storage until next year.
In many US climatic regions this unit sustains enough warmth to grow vegetables all year round. In the northern climates, you can normally jump start the spring by starting in February and extending the growing season into October. The retained heat can radiate overnight and keep frost and light freezes from harming the plants. Another great feature is the high quality automatic lid opener. In the summer months, this clever device will expand to release hot air during the days and close again in the evening as temperatures cool.
Whether it’s a condo garden on a rooftop, deck or patio, or used in a typical yard, the BioStar 1500 provides a safe protected area free of birds, pests, pets, slugs and snails. On a deck or patio, simply use standard planting pots for your vegetables and flowers, in a yard use the ground itself with compost added to amend the soil.

Review 1 for Biostar 1500 Premium Mini Greenhouse
Date:February 16, 2012
Good Quality Item
"Yes my nickname is Chicken Coup, and no I don't use my cold frame for chickens. I am buying a second unit as the first one I purchased last spring from here held up through the winter just fine. It gets cold here in Scranton PA and I was concerned about windows getting brittle but they survived the winter in perfect condition.
Its a simple product but I like how the side and top windows are thicker than most cold frames. Out here we all start our flowers and vegetables in late January through February and this unit keeps some warmth in better than most.
Simple to put together, no parts to haggle with as everything fits nicely. The automatic opening device is a plus. Don't know how it works but it really does open and close depending on the temperature.
Most of my neighbors make their own cold frames but a few of them have bought this same unit after they saw mine. I'd buy four or five but money is tight and I'll just get one per year. They'll sit end to end across my back yard in a perfectly straight line when I'm done. That will be enough lettuce, carrots and cabbage to start a produce store!
I'd give it five stars if it was half the price, but that's just me."

Review 2 for Biostar 1500 Premium Mini Greenhouse
Date:February 5, 2012
It works, kinda
Pros: it is sturdy & what was expected
Cons: cannot figure how to opperate auto. feature, gave up trying to follow directions & went by pic.
Model Number: Biostar 1500
"After assembly using non-english directions I could cut assembly time by 25% for the next buyer by writing procedure. The web site is useless. Can not figure how to adjust for temp. action. Nowhere to go for advise. The less expensive model would be my suggestion. Will never do another purchase that has no reviews."

Review 3 for Biostar 1500 Premium Mini Greenhouse
Date:March 6, 2015
sturdy, but really poor instructions
Pros: sturdy and good size -- i ordered a 2nd one.
Cons: overpriced, poor instructions
"the lack of clear instructions made putting this together a challenge. it really wouldn't be that hard to do a step by step photo shoot and put on line. also, i didn't bother with the automatic wind closer as it seemed like you had to drill it in yourself."
