I hadn't heard of using two sheets but I like the results you got so may try that. Even so it may not solve the whole problem but it should help a lot . It's unlikely to do much for established thistle but should slow down the spread of both new thistle and pigweed at least.Thanks for the info on your technique.
I had been thinking of making a frame for solarizing smaller patches of garden/paths where Bermuda grass is a problem. Just a smallish 2X4 frame, putting plastic directly over the weeds, and then another layer over the frame. Obviously this could only be used for small areas, and then moved. I decided however that it would not be more than a temporary fix because of the deep rhizomes of Bermuda grass. Solarization is not effective more than a couple inches or so. This might be effective for zapping weed seeds.
edit: It's not my idea - there was a YouTube video about reusing greenhouse mixes.
Tried just about everything for weed control. When associated with a community garden, some un-rented plots were covered with very wide black plastic. They soon became big black balloons from the foxtail grass under it. Have had success with glass storm windows over small beds. Otherwise, think Christmas and hoe, hoe, hoe! No bad plant survives steel.
Yes; nothing non-herbicidal beats chewing them up, one way or another, I don't solarize; I rake the dry weeds off (this is the season), sic Sukie on them two or three times, until they stop rearing their unwelcome heads, and plant. This is, admittedly, a bad year, so much having been left fallow during recent drought, but that process will destroy the weeds where I need to, long enough to reclaim the areas.

You may notice from my photos i use silage cover plastic, black one side white the other. I use it for killing off weedy or grass areas black side up so it basically cooks it, also its used for when i want to sit bird nets on when covering seed crops that way weeds dont grow through the net. Using clear plastic though would only be effective at frying surface weed seed during high sun periods, but then how deep would that heat penetrate?
