Bunch o' crazies! The reason why food colouring is not a good idea to put with ze weed, is that it is diluted in water, but when "vaporised" through ze smoking, it actually causes health issues. It'd be a little like smoking non-toxic glue. Health to put in your mouth, but bad for the inhaling.
Also, would be an idea to try the lemonation of the buds. Might try it out with one of me plants. (I don't let them grow too big anyways, so if it dies, it was a labour of pleasure and a little love. Nothing to get upset about)
Oh, and if music really does help, excellent, I'll bring one of me plants, next time I go clubbin'! XD Bunch o' loonies.
