I don't know how much more. I know hydroponic system like this doesn't come cheap. The entire environment is controlled. The air is filtered, temperature controlled, and humidity controlled. The light intensity and light cycles are controlled. The nutrients are controlled. Air is pumped into the roots to keep them healthy. The water temperature is controlled. Even the CO2 levels in the room are controlled. In fact, the room is so tightly controlled, that no mites or pests get into the room.

It is all about quality rather than quantity. The market these days is flooded with cannabis, but to sell the product, it must be the highest quality.
