Soil Mix Question

Hey RiU!

I was thinking about this year's soil mix and thought it would be a good idea to ask you guys. Year before last I used a mix of :

2 1.5 cf bags FFOF 22.5 gal
2 2 cf bags happy frog 30
.5 4cf bag of perlite 15
1 2cf bag black gold coco 15
1 25 lbs nature's source worm castings 2

Per 100 gallon pot

This year I was planing on just using half ffof and half happy frog, thing is it costs around $100 more, to go this way.
What plan would you all recommend?

I think your mixing a lot of shit that doesn't require mixing. ffof Is a good premade mix as is is, your making this more complicated than it needs to be, but I suppose this was to cut costs a little? So if u wanna save cash go with the original mix, you wanna save time/effort, a half, n half mix will do
