Thanks for the tip about perforated plastic film!
I always worry that my seedlings will cook, since I leave for work while it's still cold, and any sunny day is likely to be a complete surprise.
If I opened a poly tunnel every morning, they would chill before the day warmed up.
If I left it closed every gray, cold morning, I'm sure that one sunny day would kill them.
But if I use a perorated film, plus a sheet for extra-cold nights, maybe I can have the best of both worlds without being home to open flaps when the sun surprises everyone by coming out!
Also, being able to move it around looks handy. Carrying trays one at a time makes bringing them indoors impractical. But your greenhouse could be made to fit just 3-4 trays, and carry them all at once!
Thank you!
