Flowering one branch?

  1. I read in a thread here once that it is possible to flower one small branch (to verify sex) on a plant by placing a light proof cup over it for 12 hours a day while the rest of the plant is in 24-0.

    Can anybody verify that this would work? It seems like it would work alright, but I would worry about the branch not getting air flow for 12 hours a day. Would that be a problem?
  2. although I've never tried it, I've read a few stories that this is quite do-able.
    a few things to note tho -
    use a lower branch if possible
    only the growing tip needs to be 12/12
    make sure it's absolutely pitch dark
