Very true Dank: my most colourful grows are always in winter, when I can lower the night temps in my dungeon - brings out the purples particularly well.

One comment though RDG, I'm not convinced flushing with ice-water would have much of an effect on colour: not cold long enough imo.

Sir G, am I way off on this one ?
