I looked at a couple of nurseries for it.. I brought home some gypsum, don't remember what I thought that was for??????
I am going to have an assortment of chemical stuff out there with the plant stuff, the hypertufa stuff and the paint etc for the foam boxes. I have to find a way to store it all on that small area.
Guess will have to get orgainized.. after all these years that will be the day.....
