Gang,
I did search the threads first and didn't see answers to my question(s).
Background
I'm picking up supplies and my local garden store has both Perlite and Vermiculite (same price $19.99/ 4 cu ft).
The Perlite says "horticultural" grade and the granuals look like pictures I've seen
The Vermiculite has a "check box for horitcultural grade and a check box for fine med course - but nothing is "checked" (the worker says it's "med/course not fine") but the vermiculite looks like it is very small flakes - almost like sand but flatter. I picked up 4 bags but can exchange if needed...
Question(s)
- Are the size of Vermiculite flake okay/does it matter?
- Should I just go with perlite instead (same price and they have plenty of both)
- Is one safer vs the other (I guess a non issue "after" it's installed?)
- Can I use a "cheap" drywall mask or should I get a ~$25 respirator?
Thanks
Dick
