As weird as it sounds, I'm planning years ahead for my future greenhouse. I'll try to make this as short as possible.

I want to grow year round. I know it requires heating in the winter. In a few years I'll actually be able to afford the cost. Tomatoes, cucumbers, peppers, melons, beans, peas, squash, eggplant...basically summer crops are what I intend to grow. Maybe a rose plant for a nice smell.

I'm wondering where a good place to gather information is. I don't particularly care for a freestanding GH only because I'd enjoy the attachment to the house if I could do it. Size also would be an issue, I can't go super large like some of the people on here. What types of panels should I be looking at, etc. etc.

I really appreciate any help given, so thank you for that.

Cheers,

Benjamin

I would want some sort of an insulated blanket like a pool cover to throw over it at night or a system of insulated shutters that you can close. That's the only way to keep your expensive heat from floating up into the night sky. You have to be there every day to manage it, though, unless you spend a lot more money for an automated system. Those $20 "auto vent" openers don't take pool covers off and on.

I'd also want hid lights as supplements to the winter sun. Digital 1000 watt HPS or Halide lights are about 400 bucks. Based on that crop list, you'd want one of each. You can get smaller hid lights, but they are not much cheaper. They are very hot, which is not so bad when it's cold outside, but you have to vent the air when you don't need the extra heat.

Have I talked you out of it yet? It would be much easier to simply limit your winter growing to crops that tolerate cold weather.
