Yeah, I know it's way early but I have them covered in a visqueen greenhouse that I made. I'm not planting my whole garden mind ya but just something to keep the itch at bay. My herb garden Ahem, is doing fine but I need more plants in my life. Something I can sink my teeth into. lol
So Cal ain't perfect that's for sure. We have our issues too and a lot of times I'm looking at a gurilla grow in other states and thinkin Yeah that would be cool but since I hate cold weather, I'm stickin it out here.
Sounds good. I've built little mini green houses out of empty plastic bottles and scraps and such to keep seedlings warm at night, with good outcome.
If you use immature compost as mulch, and plenty of it, that'll also help keep the seedlings warm on the cold nights.
Also, if you have any Christmas lights laying around, string 'em inside your greenhouse around your plants, they'll gently warm the place up like a candle.
You can also fill up gallon milk jugs with hot water and stick 'em in there at night, if it's going to be a cold one.
Make sure the ground surrounding the plants stays warm too, as the roots need to survive more then the foliage up top.
