I did a google search and found it. You can order on line which is what I would do. You might check nurseries too.
Never heard of the other but I have been using Cloud Cover for probably close to 20 years and it was worked well.

Pretty much true, but if you want Cloud Cover in particular, you might try calling an independent nursery or order on line. I believe both of those products will raise the temperature approx. 3 degrees.

thanks for the advice, penny- i feel silly that i hadn't thought of ordering it online.
and wanda- thanks to you too. i think i will give the wilt stuff a try.
