I am starting my plants outdoors in Rapid Root Plugs inside of a green house,when the plants begin to show there roots I will be transplanting them into coa-coa blocks inside of a tray with water.When the plants roots rip through the blocks,I plan to make 5, 3x3ft.holes,What could I use as a soiless mixure for my holes?What ingridients would be best to use outdoors? PLEASE HELP
Why would you want to use a soiless medium? Generally speaking, soiless mediums are for hydro systems.
Im sorry, I meant organic potting soil like Fox farms ocean forest for my medium.So what other ingredients could I mix along with that?Or could I?
Fox Farms is perfect right out of the bag but you might want to add an extra 20% perlite for aeration (I use crumpled-up twigs to get the same result, staying organic). Have you read my guerilla grow FAQ on page 4 of FAQ?
