Since i got a problem with my hps bulb i m forced to switch to MH for the last week (14) of flowering my hawaiian skunk.. anyone has tried this? any side effects? any chance of the plants stressing? If the are any negative side effects i ll rush to the local lighting shop to buy another hps bulb.. any ideas?

You shouldn't have any problems I use both HPS and MH for flowering I find adding MH light turns my bud more frosty white than just a HPS alone.

y i m using 2x150watt metal halides and 1 250 watt hps to mix the spectrum a bit.. my previous grow was just hps and i noticed more trich production at my current grow.. it could be either the additional watage or the metal halide spectrum.. works fine tho..
