NOTES: Haven't ever used greenhouse; will not be main form of gardening, only for transplants (veggies + herbs).

Greenhouse used will be lean to or mini portable one. Can't make any permanent changes to plot; land isn't mine.

Questions are....


Does greenhouse need to be heated w/heater? If so, what kind and what wattage (must be cordless no outlets in greenhouse).


Are grow lights required or no so long as the area gets enough sun?

Do seedlings grown in greenhouse need to be hardened off? Know they're in protected area, but they're still technically outside.

I have a plan drawn up in Google Sketchup for a small one which is 2.5'x 4' x3.5' tall. This was planned to be made out of 2x2s since I have a roll of plastic that I can have.

If your looking for a simpler option you could buy one from a garden center like [url=https://www.amazon.com/Gardman-R687-4-Tier-Mini-Greenhouse/dp/B000NCTGQE]this[/url]. This would work great for what you need.

Why bother use a cold frame.
