Hello guys! First time grower here, I seem to have everything ready, room temp is stable, PH in water is just right, Im Just a little confused on the super soil. I watched tons of videos on youtube but to acquire as much products as them just starting out is kind of pricey. So far I have Promix, Mushroom compost, worm castings, prolite, gaia green 4-4-4 (1.1lb bag) and Glacial rock dust (1.1lb bag). Is there anything else I'm missing? Or can I make a sustainable soil with these ingredients? I really appreciate the help!
