Cloning buckets

New to cloning and was just wondering wether to let the pump run 24 hours or to set some sort of timer? Ive been going 24 with better results than i was getting in cups of water, but im always looking to improve. Thoughts? Appreciate you gang!

Best advice,
"Whatever is working for you, keep doing it."
If you DIY'ed it, even better.

Best of luck.

Only need to turn it off if water is getting too warm from it.
