Does anyone know how warm this greenhouse stays inside, ie., if it's 40 degrees outside, what would it be inside the little greenhouse? Thanks. Anne

the temp will be just a little warmer, but that is with sun light on the unit. They are not make to replace the glass greenhouse, just to help you get started a little sooner.

Not much warmer than the outside temperature. I keep mine on the patio and unless you are going to add a heat source, don't look for it to stay much warmer (more than 5 degrees) in cold weather than the outside temperature. I did find it is a great place to start seedlings and keeps the plants out of the wind, so there is no wind chill factor. We live in cold weather where it gets down below freezing at night and I found that it was not suitable over winter. I don't know how it will be in summer.

I am using my King of the same model to heat a greenhouse 16' x 28' x 12' with 5-wall polycarbonate glazing. The target low temperature is 55°F. The King can handle that on a cold nights down to about 18°F outside on a still night, 25°F on a windy night. When the outside drops below that, I supplement with a kerosene space heater. I could probably make it with 2 King heaters but the power is not rated for that.

It is great greenhouse quality plastic. I have it on my greenhouses and with a heater my greenhouse is 60 degrees while the outside temp is -10. As the temp warms around April with direct sun my cooling fan will kick in when the greenhouse temp reached 90 degrees.

I used it in my greenhouse during subzero temps and it works great until it runs out of propane. It has a healthy appetite so I would recommend a separate tank for it.

Dear Anissa, Thank you for writing, and for your interest in our Palram Harmony Hobby Greenhouse. To be honest, we would not recommend resizing or retrofitting this product, due to the complexity of the design. There are many parts involved and other variables beyond our contol. You would be much better off buying a greenhouse sized small enough for the space you have. I hope this helps! Thanks for making Gardener's Supply your source for gardening products and information. Please let us know if we can help you with anything else. Sincerely, Darcy Customer Service

I think it's going to depend on how cold your winter gets. I don't know if it has any guidelines about temperature (it's at my grandkids' house) - but I would expect that the material might become brittle below 40 degrees. I doubt it would be wise to set it up below 50 degrees. Please note that this is conjecture only. I know that my daughter has set it up in the garage several times during the "colder" months in Virginia.

My guess would be 40 F or less. I know our very small bird bath (28" diameter) froze at 20, even with this, so it can't be very warm. For northern Michigan it was way to cold / small.

I don't see why not. I live in Los Angeles so the worst weather we see is heavy rain, but it's very sturdy and stands up to high wind - the kind that knock trees over and whatnot. There's a window on the roof that opens and closes, so you could easily keep it shut during bad weather. Overall an excellent greenhouse.

Considering the issues I've had with this plant it is clearly tropical and MUST have extended periods of warmth of above 75 and above degrees with bright sunshine in order to grow and thrive. Anything less and it just hangs on until hot weather returns. Weather colder than 60 degrees with no direct sun will ensure it quickly succumbs to rot or fungus and dies. Even in Central Texas it's been a challenge to create the ideal conditions for this plant. So if you live in NYC and rarely use the heat and only have North facing windows which means little direct, hot warm sunshine the plant will not survive very long there. You'd have to create a mini-greenhouse enclosure to even have a chance.

You would have to be sure the bulb does not touch the vinyl sides of the greenhouse, and that none of your electrical connections can get wet. Your electrical cord should be plugged into a ground fault circuit in case water contacts the connections. Other than that, your grow light should be fine. I used a heat lamp in mine last winter when the outside temperature fell below 28ºF, using the safety precautions I mentioned, and had no problems.

I kept it in my classroom. Normal temperatures - sometimes with the air conditioner running. We did not place it in the sun.I think garage conditions would be ok, but don't miss the hatching!

The weather where I am in Virginia is such that we took the greenhouse off the garden as early as mid-March. The humidity and sun together made it too hot under the greenhouse for our favorites. I do recommend this product though and will be bringing it with me to the next garden as I move to a new house.

Eleanor, I got this for my mother. She has it up against the side of her house with heavy pots in it. She hasn't had any problems but it is in a somewhat sheltered area. We were both surprised with the quality of the greenhouse when we got it. We were not expecting much with the cost and packaging. My mom has been very pleased and it is serving its purpose for her.Hope this helps.

I started cool weather seeds this week (lettuce,spinach,peas). I'll start other plants probably next week. I watch how cold it will get overnight. If it stays above 32, I figure most seeds will be ok. By the time the little shoots have started coming up, it will be staying warmer at night. I'll bring in geraniums and pansies in the next week or two. I've been in the greenhouse the past few evenings and it is still pretty warm. I always go by Zone 4 for Colo. And I always try to pick perennials that are native to this area. You can't go wrong with any of them. They take the cold weather better. It's always trial and error with these little grow house. Good luck and thanks for asking! I started cool weather seeds this week (lettuce,spinach,peas). I'll start other plants probably next week. I watch how cold it will get overnight.

I really don't get the people claiming their greenhouse was blown down. I live in Florida and we recently had some pretty crazy weather. We have not yet bolted or tied down our greenhouse and so had gotten a little worried when the winds got crazy, but that greenhouse didn't budge an inch. I was skeptical when we first bought the greenhouse about a year ago but w are really happy with it. Its much more durable than i had originally thought it would be.
