how much actinic is needed?

[jasert39]

I'm going to run a 2x65 watt pc setup over my 20L. Current light setup is one 65 watt 10K i believe and one 65 watt actinic... would it be better to have one 10K and one 50/50 or just let it go as it is?

Thats pretty standard on all PC fixtures. You should be fine. What are your stocking plans?

I would go with the 1 daylight and the 1 actinic.
