and for the next cat skinning....ok i do this guys. i fill it with my soil very dry and loose and by the way my mix is 50% perlite. the root explode thru it, but back to the pot. i fill it with dry mix all the way to they top, and then i pick it up and bounce it on the ground to shake the soil into the egg carten looking sides and then i top off the pot and do it again. when it is full i water it with my can and 2 gallons of water with molasses in it. then i let it dry out one time, or close but not to kill my bacteria i grew with the molasses. hope it helps again guys. i like how these and all pots fill with dry soil. you cant over pack it when its dry i promise. and roots love unpacked soiless medias..... when it is watered it will always drop more and need topped of, but i dont till i plant the plant .......cb420
