I use a timer set to 10.5 hours, using a 5000k when I remember to turn it on before work, and switch to a 6500k when I get home. Each bulb has a switch, but the 5000k is a bit red for viewing. I would think your bulb would be fine. I'm thinking of reducing light to 10 hours, that might be a perfect balance, at least for me and my stock level. I'm also adding API CO2 Booster as directed and API Leaf Zone once a week.
Wouldn't you like to beside the seaside?
