If, and I emphasize if, I go back to coco it will be for two reasons:
1. When shit happens, it is possible/easier to correct in coco than it usually is in soil. This is especially the case if one tries to go water only for an entire grow which is my primary interest with soil and autovalves.
2. The hydroponic nature of coco means, other than the need to pH and monitor EC, adjusting nutes is easier. If you use properly buffered coco, a balanced nute package, and adequate runoff, you know that nute balance will not go sideways. In soil, especially in an attempted water only grow, if the nute balance or pH turns out wrong, it can be complicated and difficult to fix.
Whether I go back to coco is not sorted yet, but I am tempted. My first soil attempt was killed by gnats, and my second one, the current one, has suffered from pH issues and/or nute balance ones, and fixing problems for another attempt would be a crap shoot. I don't know, and don't have a reliable way to even determine what the problem is with my current soil mix, much less exactly how it can be fixed. I am sure that I could sort it eventually, but in how many grows? I only do one indoor grow a year.
With coco and a decent nute line, I am pretty sure that I could get the next grow dialed nicely, but I am less sure about the soil option. Decisions, decisions.
