How tight is the plastic on your plastic hoop? Wrinkles? Sags? We're installing a 48' double poly layer and just can't get it tight enough to satisfy my aesthetic, which would be perfectly smooth. Wiggle wire and channel lock. Are those wrinkles just aesthetic issues, or will it cause problems over time?

Best to put it on when you have a between day as far as temperature. Around here that is about 40º.
If you get it to tight in putting it on when hot, it will maybe tear when it gets cold.
Depending on how big your house is, there can be lots of expansion & contraction by the temperature.
Double layer needs a little slack, so the air between can take up the slack. The more space between layers, the more insulation value.
Our 30 x 96 house looks like a flag in the wind when hot & windy. When it gets down to freezing, it is tight as a drum.
Good luck!

OK, thanks very much. Bit of slack sounds OK and even helpful. The only hoophouse I've really worked in before had really tight, smooth plastic. Now that I'm putting some on myself, I have NO IDEA how they got the plastic so even and consistently tight.
