What is a "small" lighting adjustment?

SereneAquatic · 01/12/2019, 10:17 AM

I would like to begin increasing the light intensity on my AI Hydra LEDs... How much is too much at a time (percentage wise). I plan to keep the same spectrum.

The controls for the light percentages are a PITA so I'm wondering how exact I need to try to be, and how much to raise in what interval?

All light wave lengths are currently below 50% intensity.

I say adjust 2% at a time

50% of that lights output is still strong, depends on why your increasing light, what tells you not its not currently enough?

I agree the 2% increase but what's the overall increase going to be. Way easier to kill with too much light rather than not enough.

If your thinking 10% spread out over a month or so, that would work. Then I would give them 6 months to see if that increase had a positive effect, also, did the increase affect others negatively....

I think your intensity is was too low. What are you running your greens and reds at? I keep my UV and violet over 100% and the blues around 80%. You should be able to adjust any color 10% a week without any problems. I've read that a good starting point is 1 to 1.5w per gallon.
