Exactly what i wanted to know....i just wasnt sure if i had to go ahead and put the holes in myself..........lemme ask you something else.....do you think i should just flush all of them to keep things clean? Or you think i should just flush that 1 plant that is giving me issues?whats good my dude! first u need at least 5 holes at the bottom of your bucket cuz drainage is very very important dont sleep on that! But to flush all you do is use 2-3times the container of water and u straight. soooo thats about 10-15gals water and by the last 2-3gals u pour in there the runoff water will pretty much clear and your flushed!! hope that helped
