To grow weed professionally you may require a fully automatic CO2 generator. You can choose to use bags or buckets of CO2, but for a larger amount of plants or to extend your yield significantly an automated CO2 regulator is a hassle-free option. CO2 regulators release just the right amount of carbon dioxide for your plants to consume from the air of the grow room. Levels of over 1,500 PPM will be toxic to your marijuana plants, thus they have a controlled release.
CO2 generators are composed of three parts, a regulator, a tank, and the controller. The controller is an electronic piece of equipment that you are able to program to a minute detail how much gas is released into the air every hour. It is recommended to buy an all-in-one package, rather than sourcing these three things separately, then you are assured that the components all seamlessly work together. Generally, all-in-one systems have a series of gas burners which emit CO2, rather than using a pressurized tank.
Hydrofarm Autopilot CO2 Generator is a system that burns propane or natural gas and is available in low or high-altitude models. As it is constructed inside a powder-coated steel enclosure, it will avoid rust in a humid grow room. It is also safe and equipped with a two-state pilot light that prevents fire as the fuel will not flow unless the burner is lit. If the flame is disturbed or the unit tips over, immediately, the fuel will shut off. Another top-of-the-line option for professional growers is the Aeres CO2 Generator, this is easy to set up and has as few as two- to up to ten burners- and propane or natural gas for each size.
If you have a bit of the DIY bug in you, you are able to get these components separately and build a really custom system. Choose the size and price of equipment that you use, it does not have to be cheap just because you have made it yourself. Pick equipment with precision, do your research, and you may even trump the pre-made options in yield boosting output, and efficiency.
