Ok , so far so good , i can see no difference as yet between the sponge and root riot , changed the water and cleaned tray etc right through.....
1 thing that i am eagerly awaiting the result for is this ,
someone like me who grows in tight restricted hard to get to open space, carrying heavy mediums to these places can be a big pain, also disposing and moving the medium after grow that i dont re-use is a real pain and very heavy,
if the results of this are good , i am going to attempt a "sponge in pot" grow, using canna nutes , this would be cool if i can pull it off , big savings to be had , with the cost of energy right now , cutbacks must be made.....
