I wasnt being a smart ass at all,now I am, I showed you how to google you lazy fuck... lay off the weed and fucking read&learn.... UB (uncle Ben) fully shows nodes, and everything you need to know about fimming and topping, pull your head out of your ass and read it again.... Newbie little fuckers like you will be eaten alive by the old timers.... If someone, ie. Brick, Ub or anyone answers your question consider yourself lucky and dont be a smart ass, I wasnt being a smart ass, i told you what it was and where to find the answer, easier than asking fucking questions and making you look like a lazy little fucker.. BTW, welcome to RIU, Hope you have great grows,, I really mean that... Frogster
