MH wattage and spectrum

Hmmm bad growth? I say that has more to do with bulb brand and ballast type. Rogers tank has been growing like mad since we switched out to 14K Phoenix bulbs, I expected a slow down in growth but am quite pleased with teh results.
 
You wouldn't happen to have any before/after shots would you? If not, could you take a pic now, and then another in a few months? If Roger doesn't mind of course.
 
Brock if I remember correctly, the SE MH bulbs have UV filtration built into the glass the bulb is made from. DE bulbs don't have UV filtration. You would have to add a glass between the bulb and the tank with UV protection.

Maybe someone else can confirm.
