huh? Coco holds alot of water, and also takes awhile to evaporate, especially if there are no roots to suck it up. If you fill a container up with coco, water it, or soak it, like you guys do with it, and just let it sit there. even after several days, it will still hold alot of the water you put in. Then, press your fist into the coco, and see how much water comes out the bottom. Watering everyday is a waste, unless of course, your roots are sucking it up/and or your grow is extremely hot. But if its wet on top, its wet through the pot. the benefit of coco is like you said, aeration, but if your constantly soaking it, its not getting the aeration benefit. The O2 in the water you put in, is very very quickly depleted, and then the roots utilize the air pockets in the coco, but if they are constantly soaked, your not getting the best of both worlds with coco. Coco is fibrous, and holds your nutes very well also, so who ever started the myth of coco just reflects nutes, is just that, a myth.
take Neil for instance, his plants grow big, but i personally think they ALWAYS look like shit, because he is destroying the root fibers by keeping them constantly water logged. He just nutes the shit out of them constantly.
and a tip with the recharge, once a week, dont PH your water with PH down. If your PH is above 7, add 1 tsp per half gallon of water of molasses, to get the PH down to around 5.5, then add recharge, which take s your PH back up to around 8. The bennies will level out your PH in a couple hours, and all will be ok.
