    Hey, I'm transplanting into 5gal bags and wondering how much perlite to add? I'm using Pro-mix soil.

    3 parts soil, 1 part perlite.

    I too use a pro-mix based mix. I use almost 1/3 perlite. Works well

    I always use 33-40 percent. Currently i am in compost and i mixed 40% compost, 40% Perlite and 20% peat. The plants seem to really like it. Some of those promix blends have a bunch of perlite in em though dont they? which one are you using?

    Using the Premier Pro-mix, it does have perlite i mixed in, but not a bunch. The guy who got me on to pro mix got back to me and said 1-1.5 of perlite and 3.5-4 gallons of pro-mix for 5 gal bags.

    I like 15-20 percent perlite

    That's the same ratio I use when I make my own mix:
    1 part (store bought) Topsoil
    1 part Compost
    1 part Perlite
    1 part Composted Steer Manure

    So, for each 5 gallons, you should use 1 1/4 gallons of Perlite.

    1 1.5cu' bag of FFOF per 1 8.8 liter bag of perlite.. I use the larger perlite, not the small stuff.
