This industry tends to take things to extremes, and hype rules all. I'm a big believer in not overfeeding or over-saturating with photons. I don't believe in the kitchen sink approach to soils or teas. To a point, less really is more. Sometimes you see these inky black teas that have 20 ingredients, many of them dubious, and it's pretty gross. The resulting plants always look burnt and unhealthy. I see this all the time with new KNF grows.
I grew up on a farm where we used organic no-till and low-till methods for fields and garden alike. I'm not lazy, but I prefer to do as little plant management as possible. I don't use no-till due to a lack of space, but I do use water only modified coots mix specifically tailored to the high tapwater pH here. Water-only methods really help minimize the amount of work I have to do, which leaves me more time to nurture the plants' spirits, not just their physical vessels.
So, in answer to your question, no teas or FPJs or special watering mechanisms required. Just use no-till methods in beds or big pots, and straight water. If you know what you're doing and educate yourself on the correct methods and procedures, and have good inputs, after the first round no-till gets easier and hopefully better every subsequent round.
A rec operation in NV has gotten a lot of local TV airtime by doing organic no-till. They seem to be doing fairly well. They recommend no-till as the cheapest method because it requires so much less effort AND money AND water. They also use a lot of LEDs.
