Good to hear that is what i was wondering as well. With an icrease in one area would there be an effect in another area. Somebody get this man a piquiti I would love to see your results in regard to this information here. Do you think a broader spectrum of lighting would substitute for some of the loss due to the tannins? And for that mater vice versa meaning darker lights being used during the tannins process to give an even more Black Water effect? Wanted to hear your thought's?
