Perennial, Heated Greenhouse In Kentucky?

Perennial, Heated Greenhouse In Kentucky?

So I’m just speculating here, and exploring peoples’ knowledge of this. I was inspired by the wallapini, but know it works best at higher elevations iirc, and different angles of the sun in kentucky.

I imagine a green house that is set into the ground somewhat, perhaps built into a hill, that is angled so the sun falls into it at the best possible angle. Then the greenhouse would be kept warm by water barrels and compost, or a thermal mass heater, not sure what would be a good option yet. Seen ways people have done both, still evaluating.

Idk about lighting. I assume in winter the lesser light hours would mean either less production, which is fine, or no production, which is not. So my thinking is that I’d need to either introduce artificial light, choose cultivars meant for early harvests/cold areas, or both.

If introducing artifical light is a need, that’s difficult. I’d have to get a lot of solar panels abd batteries to keep up with the electricity demands, as well as get a cover to reduce light pollution. I guess using high pressure sodium lights would reduce heating costs though, so there is that.

I’d like to be able to grow tomatoes, cucumbers, herbs, maybe regrowing some celery. Basic vegetables that are staples, nothing crazy. Enough to have a moderate supply in the winter.

This is just a start, gonna add more as needed, but if anyone could give their thoughts that’s be great. I realize this would be expensive, but this is a very long term idea/goal.

Trewithen (Cornwall, England)

Trewithen (Cornwall, England)

Trewithen (which means “House in the Trees”) is a Palladian architectural style of house and gardens that has been owned by the same family for the past 300 years. The house, still occupied by the family, is not open to the public, but the park-like gardens are.
The original house was purchased by MP Philip Hawkins in 1715. He hired London architect Thomas Edwards to rebuild the house and design the landscape. Hawkins died at the young age of 37 without children. He left the estate to his nephew Thomas Hawkins. 
Thomas Hawkins, who married the wealthy Anne Heywood, redesigned the house further and began planting specimen trees and creating vistas that founded the framework of the garden today. In 1745, he published a book titled “The Care and Cultivation of Trees”.
A line of Hawkins successors continued, each making improvements and additions to the gardens. Considerable renovations were made in the early 20th century by owner George Johnstone, who added shrubs to the woodland gardens, especially rhododendrons and camellias (over 200 varieties), many of which remain today. Johnstone worked with plant hunters and brought many rare species to the gardens. The ceanothus ‘Trewithen Blue’ and the rhododendron ‘Trewithen Orange’ were bred here.
George Johnstone’s most noted addition at Trewithen is the “South Lawn” which stretches 120 yards and is flanked by stately magnolias and rhododendrons –
Trewithen boasts 18 “champion” trees (these are measured by the UK Tree Society and have been recorded as the largest living specmens). Here you will find the largest Magnolia campbellii subsp. Mollicomata tree in the UK, standing over 65 feet. .
My favorite area was the Walled Garden, just adjacent to the house –

Polycarbonate Windows for Enclosed Porch Greenhouse

Polycarbonate Windows for Enclosed Porch Greenhouse

Hi all!

I just moved into a new house that has a strange south-facing enclosed porch in the back. It currently has multiple screened open-air “windows”, so the room is the same temp as outside. My husband and I have a few ideas for what to do with the space, and one is to turn it into a greenhouse/potting shed. Since it would cost a fortune to put proper glass windows in, I thought maybe polycarbonate panels would suffice, but I wanted to know what y’all thought? I’m in 7b in Oregon, with winter temps regularly dipping below freezing. It doesn’t seem to be well-insulated, so I recognize it won’t stay super warm in the winter, but I’m hoping it’ll be warm enough for starts and maybe even some overwintering veggies. I even figured if we just screw on the polycarbonate I could remove a few in the summer to prevent the room from getting too hot.

Has anyone else undergone a similar project or have any insight into how this might work? Thanks!
