slacker outside grow..

The bright yellow pistils that protrude from the stigma, turn brown/red/orange over time, as the plant develops through flowers, new cycles will produce fresh white pistils, and with each cycle the plant will produce fewer and fewer new ones each time until gradually you will notice hardly any, all will be brown red-orange, this is generally what I use to let me know when the plant is ready to have its trichomes checked. Using this it's pretty hard to miss the cue.

I've done this before and the benefits are negligible at best, i would just let the whole plant finish on it's own.If you only have a couple more weeks left just let them ride it out and harvest at one time.I wouldn't recommend 2 runs to dry unless you lack space to do them all at once.
