How Much Soil/perlite Do I Need For 12 7 Gallon Pots?

[ChuiSoto]

So I've done a Coco grow but I went 50/50 and they were 10 gallon pots I know huge way to big so now I'm going 7 gallon and want to try FFOS and perlite so I'm curious and can't really figure it out how much FFOS will I need if I want to go 30% perlite and also how much perlite ?

By the way FFOS 1.5 cubic ft and perlite is 2 cubic ft

Hmm, I broke out the calculator here and it seems you're going to need around 84 gallons of soil.

I sent your calculations to NASA for a double check. I like 1/3 perlite in my mix. So that would be 28 gal of perlite.

There's a convert App I use for any and all calculations. Convert Convertpad is the name of the app. I use it almost daily. Has pretty much everything.
