Hey Dutch,

I believe the reason they rercommend that bulb for the last couple of weeks, is that UVb has it's greatest impact (from what I just saw) on trichome finishing. In my experiment wo/UVb trichomes stayed clear longer and changed to cloudy slower without UVb and never produced any amber ones.

Here's my last obsevations, since drying and manicuring;

1) The finished buds have less odor wo/UVb, they lack the sweet/pungent smell that I usually have with WR.

2) Potency seems to be slightly less wo/UVb, myself and a few tasters could tell a difference but it was very slight. Tonto preferred the wo/UVb saying only it was a better overall "to him". Again a product of no amber trics?

3) Finished weight was down a bit, averged .42 grams per plant less wo/UVb. That does not sound like alot but in my SOG grow it equals 2+ OZs for the run.

I'm not going to give up the UVb supplemental lighting anytime soon. It did not do everything I thought it would, but based on just finishing times and wgt differences I believe it is worthwhile.
