Whodi.....It is impossible to "drown" your plants using coco. You can water them all day long and the coco will maintain the same amount of air pockets.
Wrong, try a 4inch plant in a 5gal bucket you just saturated to runoff. water it every day till run off. i bet the house it would be one shitty ass plant, and soon dead. better yet add in the possibility, vegging in a 70 degree room with the bucket on the floor under cfl's.
how else will you know if the coco is fully saturated?
By knowing the weight of the pot. but i agree that picking up every pot in a large grow may be cumbersome and time consuming. especially if drippers are everywhere.
just my opinions.
Whodi grow on, im interested in your results.
Grow on & b-safe
