Nice thread!

Weez, I scanning as fast as I can right now, but I think you posted a comment about how hard BLB (Blacklight) Inc.'s filaments are run to produce more UV.

My research (not that I'm right, but) indicates that the filaments are identical and the only real difference the bulbs is the BLB glass (Wood's Glass) used in the outter envelope.

In other words the Far Red output of the BLB Inc.'s is basically the same as the Clear Inc.'s, the main difference in visible emission.

I dissagree with UV results as false Far Red positive possitives as the light sources used usually indicate. Far Red doesn't give hit and missed or "mostly" results.

I use what I personally have experience with. Considerring the cost of Clear Incandescents verses the cost and added complexity and DANGERs of ballasted UV lamps, I would suggest serious Qualitative growers get "EXPERIENCED" (Jimi Hendrix).

Gotta Run (crazy work load today).

Take Care, Sal.
