Trying to make my own soil based on the 'Organics for beginners' formula. The problem is that I can't seem to properly convert volumes to suit my needs.
For instance: 1 cubic foot is equal to 7.48 liquid gallons or 6.43 dry gallons according to all the online sources I've seen. Because these are all dry ingredients that I'm mixing (soil, perlite, EWC, etc.), should I just use the dry conversion? All the posts I've seen on this site say 7.5gal/1 cu ft.
Now consider the bag of Fox Farms Light Warrior that I have and will be using for seedlings. It says "1 cubic foot (26 dry quarts)". While this supports the 6.5 dry gallons to a cubic foot conversion, it flies in the face of every calculator I've used which says that 1 cubic foot equals 29.92 quarts.
In short, I need to make a basic mix with a ratio of 6-2-2 (soil, perlite, EWC) and lime at 2 Tbl/gal. I've got roughly 2.2 cubic feet of pro mix, but I can't figure out how much perlite, EWC or lime to use because I don't know the right conversion! I swear I'm not this dumb in real life.
