I always hem and haw about replacing the AG bulbs, don't want to spend money on it, etc. But! I just replaced my Pro100 bulbs for the first time since July. Big difference! Very visible change in light. And my bio PAR detectors (Korean red curl lettuce) agree - the lights are brighter. (The lettuce got redder overnight.)

Has anyone convinced themselves that 6 months (instead of the ~9 mos I've been averaging...) is really best?

I wondered about that.  It's good to know.  Thanks for posting it.

Hmm..  maybe save the old bulbs for seed starting?
