Here is my solution to the coco issues, and a few others! Best investment I've made in my growroom, Auto Pots. Self watering in measured amounts, VERY simple mechanical valve. You can get pots in 2.2, 3.9, and 5.9 gallon pots I've seen guys grow 1000+ gram plant in the 6.9 pots!
You can get various reservoirs with them, or DIY one. I found a 23 gallon waste basket at Lowe's the same shape and depth as the stock 12 gallon, just wider and taller.
Auto pots has a video on how their valve works, its ingenious, really! The tray below the valve has to become pretty much dry, before the valve will let water in again. Pots absorb the water, then get to dry a little bit before the next watering/feeding.
the 12 gallon res will feed 4, 3.9gal pots for about a week.
If you have bigger plants and/or smaller volumes of soilless mix it can easily become necessary to water several times a day. Even in 5 gallon buckets I'm seriously considering an automated watering system to water twice a day.
