77.8F isn't bad, but if temperatures start getting past 80, I'd consider adding some extra ventilation to cool things down. Things like humidity, C02, etc., can all play a role in just how high temperatures can get without affecting growth, but since those don't really apply right now, you should try to keep the temperature between 70-80F for best results. With an open hood like the one on your light, you could probably lower the ambient temperature of the entire room by having a dedicated fan just blowing on the bulb, and moving the ballast out of the growroom (if possible).

I just water them when they need it. I know it's sorta taboo, but my seedling pots are somewhat translucent, so I can tell just by looking at the soil whether or not it's still moist, completely dry, somewhere in-between, etc. When the topsoil starts looking a little crumbly, it's probably getting pretty close to time to water. Smaller containers mean you'll need to water more frequently, and higher temperatures will play a role too. If you're not letting them dry out completely, and yet aren't keeping them saturated at all times, then you're doing it right. :jointsmile:
