What quantities are you looking for? I go through a lot of soil, so I buy the monster bags:
SunShine 3 cu. ft. Peat Moss
Vigoro 2 cu. ft. Organic Perlite Soil Amendment
I've also use the Premier peat moss that ChefDean mentioned. It works fine, but I'm not a big fan because of all the twigs and sticks that I have to pick out.
The last time that I bought perlite, my local Home Depot store had changed brands to Therm-O-Rock. I've never heard of this company, but it was still plain perlite.
These brands of peat moss and perlite are safe to use:
- Sun Gro (Black Gold) -- SunShine is a Sun Gro product line
The problem that I find is many local garden centers only carry Miracle-Gro products, which are unusable due to the added fertilizer. My local Ace Hardware store carries Sun Gro products. If nothing else, you can always buy smaller bags on Amazon and eBay.
