Increasing photoperiod on XHO

[ryshark]

Is one XHO bar powerful enough for the need to go slow when increasing photoperiod time?
I recently decided to increase my XHO duration from 10-hours to 11-hours over my tank which only has a few acro frags. So far I have been doing it very slowly at 5-10 minutes per day over the last few days. It is just one XHO bar mounted to an 8-bulb T5 fixture. Is it necessary to go this slow or can I safely increase the time up by less than 1-hour in 1-day. I'm not sure how much PAR one bar puts out.

When making photoperiod length adjustments I typically go by 1 hour increments weekly. I’d say you’re fine to jump to it. Going slower won’t hurt though
