ad lots of purp food coloring to your res. and chill with ice maybe either behind your fan so it sucks the cold then blows out or just in front of your fan. try throwin your bud right into the freeze right after you chop. leave in for a few days maybe then take out and dry. me myself could never bring my self to treat my plats so horable after all that work but good luck and im interested in seeing those girls after the abuse lol. guess im a bit twisted. purp max will enhance a already purp plant but wont do anything if it has no purp to enhance.
