i read about the dwc or bubbler on overgrow but what i dont uderstand is lets say u are using a 5 gallon bucket with a lid and u cut out hole on lid for the net pot. it says you fill the bucket to about and inch from the net pot. okay do u put medium like hydroton in the bucket or just liquid nutrients and if u do put medium in how do change the fluid every week or so because if u lift the lid that would pull the roots out i think and the second question is if the water line is an inch away from net pot do the roots have to touch the solution or can u make the water line to actuallt touch ur roots and as the roots get longer decrease the the level down to about an inch or so. so basically i have 2 ?'s thanx appreciate anyhelp.
water/nutes in the bucket. hydroton or simmler in net pot. to start the roots shud b kept damp but not wet. after a short time the roots grow out of the pot and into the water, then the leavel is kept around the bottom of the pot and the roots grow in the water.
