Would these be good to mix 50/50 for all on one soil to grow in… Im new to the soil game
Stay with the FFOF, it is amended with beneficial microbes and nutrients. PH your water at 6.5 and that’s all the plant will need for roughly 5-6 weeks. Around week 4 I test the run PPMs and if below 900 adjust nutrients and feed for the veg cycle and bump that up to 1000. Always feed/water to run off to expel those nutrients un-used salts and minerals that could potentially lock out your nutrient uptake
Just what @OGIncognito said
Coast of maine stonington blend is also good for an all in one super soil.
Also, don’t start you plants in these super soils. Start in a basic potting soil or seedling starting soil and then transplant into the super soil after they’ve sprouted and grown for a week or two. Seedlings don’t like strong super soils.
I’ve tried a couple different brands of castings and Brut was my favorite up until I started raising my own worms. Sounds like it’s trying to be the starting point for building your own living soil, if you were interested in going that direction.
If not, see above.
