Idea!!!!

Ok so i've heard people say make a fire on top of your garden then till the ash into the ground...now if you saved your bong ashes and when you had enough ash to mix it in with some foxfarms soil(or w/e) would this help in anyway or just be a waste?????

you mix ash in from a fire pit or burnt newspaper.... you put it on when you switch to 12/12= big buds

ok but can you use your bong ash as well since its from the plant would it be good for it????
