Thanks oldmac, I do have a grasp of the basics... I've been reading up on some of the advanced techniques with light and scheduling and have been wondering what is valid and what is not. Thanks for the clarity on the 36 our darkness issue.

Something like a PSMH, or CMH or even a MH in that range. It makes a big difference with getting trichs to turn amber.

PSMH - is that a conversion bulb? If I could run a CMH I definitely would but unfortunately it requires a coil/magnetic ballast or a rarefied electronic ballast neither of which are in my arsenal.
