you fill the nutrient level to just below the netcups the bubbles from the airstone pop and spray small droplets onto the substrate great for cloning and plants that already have roots hanging out the cups but until you have a little root growth out of the cups you will prob need to supplement with a drip system or just hand water for a week or so until the plant establishes roots long enough to actually get splashed with nutrient . i normally use a pot on pot system the top top is filled with clay beads and has a dripper flowing through the beads into the bottom pot and back to the reservoir i also have airstones in the bottom tub wich splashes the bottom of the beads in no time at all i end up with a brick of roots in the bottom tub. but without the dripper they initially wouldnt get anything and as my tubs are like 15 litres each the top tubs roots wouldnt get nutrient but with such a small pots who knows the airstone alone may do it but i doubt it. hope this helps give you some ideas .ps get a small pump and drip as well.
