I need help setting up my first hydro system

Coco rocks. Once you get it dialed in it's a breeze. I run 100% coco with Blumat watering system. Gravity fed, no pumps.

I have no experience in coco but I figured I would have to water 1-3x a day. If a timer that only does 1min increments is good for this, i'll get it.

It depends on the output of the emitters you choose. With normal 1 or 2 gal/hr emitters you can totally use the 1min increment timers, even if have have multiple emitters per pot. I would set the timer to run 3 to 5 times during lights on and one time during dark.
