Thanks :fun4:
I run 2*250W MH + 4*T5 (2 blue & 2 actinic) by Giesemann.
Photoperiod 6hr MH and 8 hr T5.
I used to run these 8 and 12hrs respectively, but decided recently to reduce the light period to see if I can see any noticeable impact on growth, and coloration. Let's see how that goes...
In the sump, for the macro, I run 18 hrs standard fluorescent light, with inverse period vs. DT, i.e. on all night and off 6 hrs in the middle of the DT light period. Objective of this is to smooth out the Ph swing throughout the day.
