Hello everyone, my name is Evelyn and I am addicted to Hypertufa :-)

I took a class 2 years ago, and never had to buy a pot for my plants since. All pots always came out great, until now.

Reading through your forum I get the feeling my old bag of Portland Cement could be the reason. It had hard pieces in it which I hammered to dust. I know laugh at myself for being so stupid, and I am just glad I did not make more than one batch.

The pots stay soft and crumbly and fell apart when I took them out of the mold.

just to be sure, it would not be the colder and less humid time of year that's causing this failure, but the old cement?
