when you have a plant in a 5 gal bucket I know you start with water about an inch below basket and as roots come down you slowly can drop water level, my question is how much water do you end up with at it's lowest point?? I have about 3 gals I start with when I change water out and Sunday will prob change that to 2 1/2 gals. will post some pics later. also it seems that nute stain has gotten the roots again. seems to have started and then water level went down and the roots at the level where the water level was are dark and such and was thinking I could take a spray bottle and rinse and clwean them off, sound like a plan??
