For the record ..i dont have a piss pot in my grow room.! It's something i read! Only a few cc's of urine to about two litres of water and 2 oz of sugar..change change/discard after two weeks or the alcohol content will kill the yeast[ oh brewers yeast can also be used] People put Bat turd and Fish paste IN grow media ,farmers spray Horse shit all over their fields .so a few drops of slash ain't gonna hurt!
