So, how many bags of perlite (1bag=1oz)would I have to buy to equal one cup? I think 8 oz equals one cup, right? I would need roughly 5 cups (40oz or bags) of perlite to be safe from reordering again. Since I am a "whip" and do not want to buy stuff from a store because fear of killing my Cp's due to hidden ingredients. I believe this is the safest method.
So, much for courage but this is dealing with CP’s and I can not take any chances…
