Distance from Lights?

Actually, I don't recall reading how much he waters each of the three times per day. So most likely it's too much water, but you don't know that yet.

No I Dont over water my plants... They are in small containers right now, The extra water is released out of the bottom of the container,

The dirt dries up quickly, so Usually I'll mist my plants with co2 water, or give them water depending on how dry the soil is.

What is the preferred method to water? When? And to what extent?

Maybe every three days.

go back and read the thread bong. If you are getting run off on seedling your are watering too much. Be sure to dump that runoff water. dont let your roots sit in it
