Nevermind I found this:
"There has been some confusion as to building a manifold, and how much time it takes, i have found that building a proper manifold only adds an average of 10-21 days on to the total veg cycle, but i average about 14 days......the more you Main-Line, the more you will learn exactly when the plant is ready to be pruned and bonded....one must watch the plant very closely for her to tell you when she is ready to be pushed....
newbie growers don't really have this down yet, and it translates into added veg time.......also, clones take longer period.....
i highly recommend beginners starting out main-lining with a seedling, they are geneticly programmed to build a strong root mass out of the gate, (which is critical when it comes to how quickly the young plant will recover from pruning/bonding), as they are putting on early vegatative growth....a clone is a bit more tempermental."
