Get clear plastic, 6 mil at a builder’s supply. It costs about $ 30. a hundred foot roll and will be enough to cover a small greenhouse with a double thickness that will last a couple of years. It is what I use on mine.

Can I start seeds outside in a little plastic tarp green house?

Question by shampoomaker: Can I start seeds outside in a little plastic tarp green house?
I want to start some pepper plant seeds today. I normally start my seeds indoors in plastic trays under grow lights. I live in northern Florida and the weather has been in the 60’s-upper 70’s the last week and was wondering if I could start seeds outside? I’d like to build a little tent using opaque plastic drop clothes and put the trays in there where they would get plenty of sunshine during the day. Will this work and start the seeds correctly?

That would probably work but keep in mind parts of north Florida will have temperatures in the mid-to-upper 30’s for the next few nights. I’m in NW Florida and we are expected to go to 34 degrees tonight, 36 tomorrow night and 37 or 38 on Thursday night. Since the seeds will not sprout between now and then you should be fine. I have not started my peppers or eggplants yet but will do so in the next few days.

Good luck and enjoy!
