Setting up my green stalk vertical garden tower. Each tier has 6 pockets and is 10" deep. Each tier holds 8 lbs of soil. There's a total of 5 tiers, 30 pockets to grow and a patened watering system. I'm making my potting mix cause it's cheaper the buying Fox Farms soil. I'm using coco coir, compost, earthworm castings, bone meal and perlite. I ran out of perlite and I could use some some compost. This is when working on a farm comes in handy cause we have both over there. I'll be going through tomorrow to get both.
