Preparing soil for planting

I’m starting a grow using Mix A. Soil for the bottom 1/2 and Roots Organic top 1/2 of a 3gal fabric pot. Do I need to do anything other than filling the pots to prepare for growing. I’m planting Fat Bastard autos


Are you putting seed in soil or you growing them in smaller pot then transplanting them

I’m going to use rapid rooters. I’m wondering if I should fill my pots a while before I plant and let the soil settle or just fill the pots when it’s time to place the rooters. Seems like I read somewhere to wet the soil thoroughly and let it sit for a time before you pant. Any insight is appreciated
