I JUST GOT DONE WITH 12 IN MY 4x4!!! 2 ROGs,2 AVTs,2 FORUM STOMPERS,2 CQ X 24 CARAT,1 WW AUTO,1 SOUR CRACK,1 SKYWALKER X FRUITY PEBBLES,and 1 FORGOTTEN COOKIES!!! I WAS TAKING THEM OUT EVERYTIME I NEEDED TO WATER THEM... THEN I JUST DECIDED TO ALMOST RUN IT LIKE A HYDRO SET-UP CAUSE ONCE THE ROOTS GO OUT THE BOTTOM OF THE POT,I FILL UP MY FLOOD TRAY AND LEAVE IT UNTIL THE WATER IS EITHER SUCKED UP OR IT EVAPORATES... IF YOU GET YOURSELF A WATERING POT,MAKE SURE IT HAS AN EXTRA LONG SPOUT TO REACH ALL THE PLANTS...
