mazon has 5/16 x 24 x 188 for $37.20 per roll. It is polyethylene and says single air bubble- doesn't look like bubbles are big

Home Depot has 1/2 x 24 x 250- large bubble, pratt bubble cushion $80 double pack (can't tell if there are two rolls at this size but I think that's what it's saying)

I want to wrap my 6 x 8 greenhouse. Just wondering which bubblewrap is most efficient. We are in central Texas - so 12-14 freezing nights on average - but it can get down to 22.

Just found this great article. It says get greenhouse large bubble wrap as it's got uv protection in it. So guess I will go that way.

Carol, take a look thru this thread for some more ideas and links.
The thread "Solar Covering Over Our Greenhouses" in Greenhouses forum

Thank you Evan!

I have already posted numerous statements on what I use to cover my greenhouses. I chose to use some really heavy solar blanket material (with a 10 year guarantee) , something that blocked UV yet allowed plenty of light to grow plants, and something that had a good and proven heat-retentive value. Simple bubble wrap would certainly be better than nothing, but would likely not last more than a season, particularly if applied on the outside of the structure. My statements are only based on personal observations.

@Ecscuba , many of the answers to your greenhouse questions can be found in the Greenhouse Forums.

I ended up ordering the solar pool cover after all. Did a lot of googling and reading garden webs, including this one, and it seemed like the best way to go. Thanks for the responses. Appreciate it

Keep everyone posted on how the solar blanket material works for you, Carol.
