@tinker @feld >> So I gotta ask, why did you comment and why only by way of introducing obstacles without solutions and in such a definitive negativity?

Most of the ag tech secret sauce is intellectual property. Take for instance my nutrient analyzer that is basically something that doesn’t exist. The algorithm I’ve made for managing humidity. Root oxygen control and then co2 management. That’s not to mention the pH and implications of growing to nutrient uptake. How you must balance that and what to use exactly to do it. How do you maintain a stable acid balance? Vinegar sorta works. Off the shelf pH control is generally phosphorus based so you can mess up your phosphorus balance.

72 variables that must all do a dance that I’ve automated in software with hardware. No easy task.

Not to discourage you but it’s a lot of time and energy spent in this to get there. It’s also cost me more money than anything in my life.
