However, drip emitters DO need frequent checking because they can get clogged with slime.

Ebb n Flow is also very low maintenance, but you have to check and clean the pump filter weekly in any recirculating system.

Drip to waste in promix is similar to coco but the pH changes over time and you will need to monitor runoff to avoid problems.

With any system that is intended to be hands-off, the quality of your nute is very important. I'm not saying, "run out and spend $400 on a nute system", I'm saying that you should do some research on nutes that are forgiving, unlikely to burn, and are buffered at the correct pH for your system. I have been VERY pleased with my results using the Canna Aqua line, which is essentially a hydro-organic fertilizer buffered EXACTLY where your plants need it, so you have to check pH less often.
What exactly is Coco? How is it different/better than soil or other grow mediums? Would you suggest using Cana Coco nutes with that or would you stay with the aqua line?
