Discuss.

I'm not sure it would increase yield, but in situations like yours, it might be useful where you have an early surprise cold snap.

Looks like a mix of PEG and Glycerin on the label as active ingredients, but the company touts 5 ingredients that work together.

I could see, potentially, two uses... if it helps improve cold weather performance, say at 40 degrees if the plant stays happier, that would be good for me.

The other use might be in late-August when we have another cold snap and it's difficult the cover the entire plant.

Of course, I'm skeptical, and would probably try it on only one plant if at all.

From the website above:
"FreezePruf (and Mother Nature) effect different plants – differently."

They don't know the difference between "affect" and "effect." Such grammatical collapses always concern me.

All kidding aside, if you’re going to order this stuff, why not perform a little controlled experiment with it? Start a few zucchini plants, set your freezer between 30 and 32°F, and run some time/temperature exposure tests using one treated and one untreated plant at a time. Throw two plants in at 30 – 32°F for 30 minutes, and see if there’s a difference. Then, progressively increase the exposure time and see what you get, trying to duplicate the results listed for Plant Group 1 in the table on the following page.

Why discuss when one can test?

Well, that's an interesting idea. I might do it, if I decide it's worth a try. It's available locally for $17 a quart... kinda steep when there are so many other things to buy.

I checked the ingredients, it's about 2% polyethelene glycol, and a very small amount of glycerin. The rest is mostly water. It makes you wonder if you couldn't make your own.

Tell the place selling it you want to perform a test before you invest in the product. Lay it out to them, and see if they'd be willing to spray the test plants for you as you're performing the test. Just make sure to keep good documentation in terms of notes (times/temps) and pictures. They might be interested in having a local "success story," something beyond the promises of a website or product label.

The worst they can say is no.
