i’m going to say if you get the big bags 2 maybe three pots… more than likely just 2 with some left over 5 pots with 2 bags if you even everyone out good…lol ---

I have a 4.5 gallon bucket which measures 1ftx1ft. So the area of a cylinder is A=PI(3.14) x radius/squared x L. That would give you 3.14 cubic ft per pot x 4 = 12.56 or times 5 = 15.7 cubic feet ---

Well I’m glad you gave me the answer to that equation because I don’t think I’d be able to find it lol. Are there any other things you mix in to it? Perlite etc? ---

Yes They say to add perlite helps get oxygen to the roots ---

I’d say a good ratio would be 20-25‰ but that’s just my personal opinion ---

The exact science on this is a bit unknown, but the deal is 4 handfuls per 5 gallon bucket unless you have smaller hands then 5 or if you wear catchers mitts then 3 should be enough. 😀 but seriously… I just add it and mix it until it looks like my soil is aerated well and I never really measured. @MAXHeadRoom thanks for the tag and hopefully it helped. ---

Got three golf leaf in rapid root starters n I’m thinking I’mma make my supreme haze n outdoors girl now so I don’t have to worry about her out growing the little box she’s in waiting for the big one to clear out. Good news I think I’mma start the grape ape seed I have for my big cab or maybe just do 2 autos in it.
