i agree with max veg period. it should be 16oz cup anything you can do!!!(i made the dwc beercup)there should be a max veg period... 12/12 from seed or 3 weeks veg something like that.
hydro or soil (saw someone constructed party cup DWC WTF?!)
CFL only i'd say for fairness sake. party cup under HPS may have unfair advantage for yields.
that's all i got for ideas.

if it's only cfl's I(and afew other) are out. does it really matter? wouldnt you like to beat someone using a better light then you?
their are advantages to not having an hps(heat means ill water like 10 times a day,cups might melt? i dont know whats going to happen)
i think the more different scenarios going the better(learning experience). im doing some under my hps and some under floro tubes whether there in the comp or not.dont you want to see the difference cfl's to a 400w make on a beercup plant?if its tiny ill sell my hps and buy cfl's for now on.
