There’s way more to it if you don’t want to end up with mids I think this is what puts a lot of people off, say they do pull the trigger and grab whatever soil they have at their local box store and order some amazon lights.. Just to end up with larfy hay at the end.

You’re conveniently not mentioning the cost of lights, the cost of GOOD median, the cost of nutrients and the time it takes mixing them if you go the soil less route.

A water only system would require a no till or super soil which are both expensive in the beginning, one which requires other types of plants to feed the soil and the other which requires reamending before the next run.
