Controlled environment agriculture = greenhouse. There are two scales of this operation: small scale low-tech option which require just thermostat and fans and then you have big scale high tech versions that costs many millions of dollars and come with all the controllers built-in. For low tech option there is just not enough margin and leverage to make it worth spending your time on it. For high tech options you are having millions in debt and another million or two in running cost (labor, seed, electricity) and with margins in single digits you are probably don't want to risk playing with your recipes. Safer bet is to outsource your tech needs to the companies that have teams of people working on just one single problem.
