lordsoth666 thanks for writing. i'm trying my best to keep up with the shortcut words. what is WTF? i know i have a Nutrient Film Technique... what is WTF? LOL basic questions, i know. as for not changing it back to nft from bubbler, my WHOLE set up is for the nft system and i want to make a bubbler as a place where i put my clones after they have rooted in perlite mix and have them sit in the bubbler and grow until my nft is out of 12/12 and harvest. then the next set of ladies goes in. but thank you for your advice. i WILL remember that as things always change. take care
