When you get the hydroton really rinse them they always have clay dust on them before putting them into the net pots.

The Spartan timer can be set with daytime on/off and night on/off settings. It has a photocell which will tell it to switch to night settings. If you have that timer you set it for 5 minutes on 15 minutes off during the daylight hours.
At night set it for 5 minutes on and 45 minutes off. When you get a good amount of roots coming out of the rockwool change timer to 5 seconds on 15 minutes off in daylight. at night 5 seconds on 1 hour off.

With a regular timer it all depends on what the least amount of time it can run. If the least amount of time is 15 minutes then on for 15 minutes off 1 hour then if you can do on/off all day and into the night if the timer doesn't have separate day/night. If you don't have enough setting on your timer to do that then you'll need to run the water for a longer time during daytime. Start it off at sunrise let run for over an hour if you have to. Then space out the timing during the day make sure it gets watered around sunset. Save 1 setting for a middle of the night watering run once for at least an hour.

Water temps for seedlings if you can get the temps between 65 - 78 degrees you'll do fine. When roots are coming out of rockwool you can be between 75 - 80 degrees. When in dutch buckets just make sure water temps don't go over 85 degrees.
