Already using the combo of HPS and MH as suggested in the advanced forums here.

The MH has the highest blue band I could get. (Using a 1000 HPS and 400 MH.)

Trichomes are actually visible to the naked eye. My estimate is doubling of the trichomes per square millimeter. I also sense greater potency in the same mother's line.

The blue bulb was over $100, but it was well worth it. This one change made more difference than any fert, nute, soil type, hour change, anything and it was a remarkable difference.

The plants coming out get their last 2 weeks under the blue which is just adjacent to the normal 1000 so it still gets some of that too.

Thank others, not me
