Light cycles?

I am almost dont setting up the rack I just built. I am using flexwatt on the back wall for heat. Rack will be stored in closet.

My question is, do you have to use a day/night cycle with lights if using a rack system? I can accomidate if needed with a timer but was wondering if I had to use the light cycles to keep them healthy.

If it's needed do I go by what it actually is in my area for day and night or is there a specific time schedual?

Nothing is needed but the natural light coming into the room already. Is the room is fairly dark during day time then some light in the room may be needed.

yeah it's actually a dark closet with no windows. So maybe a single low wattage "day spectrum" bulb should suffice?

you can buy cheap 18" shop lights you can hang in there and be enough for what you need.

ya u shouldnt need anything big in there. just something big enough so they can tell the difference between day and nighttime to keep their sleep schedule straight.

Nothing is needed. I've talked to a few successful breeders who keep their balls in rooms with no light. The only time they turn the lights on is when they're in there working.

It's no problem either way just seeing what others here do. I got my flexwatt, cords, and clips today so I can finish them and make the transition.
