Remember those little egg-shaped house trailers popular in the 1950's? Somehow, we acquired two of them back when we were developing our property on Bainbridge in the 1980's, and although they're hardly in "vintage" condition, they are still serviceable, especially when you've got a little farm or garden operation.
Several years ago, we rearranged the interior of one trailer to accomodate seed trays and growing lights, and this year, I've got seedlings in one trailer, and baby chicks in the other. The nice thing about these old trailers is that they usually have one large window near the "dining" area, and when the sun comes out, seedlings can enjoy the rays. The metal walls heat up nicely and usually have a little insulation, creating a greenhouse effect. The old slatted glass windows grind open to allow ventilation, and both of our old ladies have top-hatches as well, to increase circulation. The windows and doors are screened to keep out the bug population. Even the kitchenettes have possible uses - ice boxes for seed storage, kerosene burners to make a cup of tea.
Even with leaks here and there, our "greenhouse" trailers may last another decade or two, and in the meantime, we'll keep them out of the landfills...
Seedlings seem to like the sunny windows, and it's easy to hang extra grow-lights
The heated sprouting mat fits nicely into the kitchenette!
