I need some more information about this! Dimensions/materials of the greenhouse? Temp inside? Temp outside? heating system?

Any information would be greatly appreciated!

I love your projects, John! They get better and better. How did that swivel arm work out for you this year?

eaglesgarden, it is a Rion 8 1/2 by 8 1/2 ft with twin wall polycarb panels. I heat it with a 10k btu blue flame heater set on the lowest setting. during the coldest part of winter, it will keep the min temp between 50 and 55 deg f.

ribbit thanks, it worked great along with the kneeling pad. I used them on every bed. No banged up knees at the end of the day.

thanks!!!

John - You're so mean!!! Why did you have to post that photo of your GH? Dangit, you'll have ripe tomatoes at christmas....LOL. I can see you now, sitting in a lounge chair while sipping on a BM - and thinking about EG's "lack of any kind of season extender". I'd really like to have one myself, but the only location for one is in the front yard (which is not gonna happen). I do have a question, though....What are your heating costs for the winter? I'm planning on incorporating three 4ft x 4ft dome style hoop covers into my raised bed for propagation purposes, and haven't decided on a heating method yet...

Hi EG, long time no see. I heat the GH with natural gas, it is on the same line as the house, and garage so there is no way of telling what the actual cost is. I have sat in the GH before sun up with temperatures outside less than 32 deg and high winds. I was surprised at how infrequently the heater came on. I cannot say that about other GHs that I have owned though. In AL, I suspect that you will have a bigger problem keeping any transparent structure cool when the sun is out even in winter. On a clear sunny day even in winter, the GH will be at 90-95 deg.

You had better get something going, with Granny in AZ with her garden and my winter garden; we will have you pacing the floors before spring. ;o) ;o)

John - No sir....I'm not doing that whole "winter gardening" thing again. I'm really wanting something to put my transplants in, when they become too big for the propagation chamber. You've got me thinking, though....What I need to focus on is some thermostatically controlled ventilation.
