Is washing perlite necessary?
I've put 8 days of my very limited free time into making 4 earthtainers and I'm now at the point of filling them with grow medium. I keep seeing people talking about washing perlite... I tried to find a source of large particle perlite in large bags, but I was only able to find 8 quart bags of Miracle Gro brand, which doesn't look like large particles at all.
What's the issue with perlite if you don't wash it? At 8 days of free time already spent, I don't want to take another couple of days to wash 4 cubic feet of perlite if the payoff isn't worth the effort.
