I am probably overthinking this but......
I can get vermiculite from our masonry supply house for $14.00 per 4cuft vs$32 for the same amount at Agway. Agways is hortacultural grade and the masonry vermiculite "is for filling cinderblcks" that was the best I could get out of the person at the supply house. Can anyone tell me why I shouldn't go with the $14.00 vermiculite. Unless they have soaked it in ddt I can't see a difference. Because of all the EPA rules and standards they have today I doubt that the stuff they are pouring in your blocks is going to be anymore hazardouse than what you would put in you garden. Would love to know what you think because I plan on picking up my material for use tomorrow night.
Also...what can I substitute for fireclay because the supplier doesn't seem to have any and says it is expensive. It's just to be used as a leveling bedd for the floor I believe so there must be something else that people have been using if any.
