r u doing high or low pressure aero? Low pressure is easy enough to accomplish and is done with spinning misters and low volume pumps. High pressure aero would have you use solenoid valves, tanks and those other kinds of misters whos name escapes me. J-misters? At any rate, I tried the high pressure and spent a ton of money on it, just to discover all the hassles that come with it. I down graded to low pressure to finish the grow then switch to E&B when it was all said and done. I started with fog, went to high pressure aero, then low and finally settled on E&F. Tried them all and E&F coco is by far the easiest, cheapest and hassle free. Not to mention that the growth rates are right in line with the best systems available, maybe a few days less at most.
