Watering detail; how often do you water? When to start using feed?

Watering at night? Is there any benifits with saving your watering to corispond with lights out?

I personally have never weighed the pros and cons of watering at night. I have however gone through periods where I watered during lights out due to having a f-ed up schedule that was hard for me to get to the plants while the lights were on.

I speculate that the advantages of watering in correspondence to light on/off would be plant dependent or even dependent upon your entire operation.
