We know of a number of national cannabis specifiers who are compensated by building growing facilities that come in under budget. They do this in part by using old technology like HPS grow lights and not LED grow lights. But while they do this, they are also very much aware of coming energy consumption limitations in their state.
The future of cannabis grow operations lies in LED lighting because it is simply more efficient – and with energy consumption limitations just around the corner in most states that have legalized cannabis, these national growers know that time is running out. They are currently looking into how to incorporate LED lighting into their grow facility plans.
The writing, as they say, is on the wall in regards to energy consumption limitations
Some states, like Massachusetts and Illinois, already have energy consumption limitations. In Massachusetts, for example, growers with facilities 10,000 square feet or larger can only use 36 watts per square foot. Smaller growers have a limit of 50 watts per square foot.
There is also governance for growers using renewable energy sources. Commercial growers who get 100% of their energy from places other than the grid have no limits to how much energy they can consume.
In Illinois, recreational and medical cannabis growers have to meet certain standards for energy and water usage. Under the law, growers in Illinois must use automatic watering systems and limit the amount of runoff water that is produced. They also have to collect and filter wastewater so it can be reused. Growers are also limited to no more than 36 watts per square foot (so, similar to Massachusetts) but the Illinois law goes a bit further, stating that growers must use high-efficiency lights approved by a non-profit group.
