Indoor-Grown Weed Is Spewing Carbon Into the Atmosphere

back into In the days of pre-legalization, cannabis production meant that rarely visited patches of land were moving in and out, or that it meant moving the farm indoors – usually in a cellar where your produce Will not be visible from outside world. But the power involved in illuminating the basement’s growing space was legendary.

With legalization, it is really just the scale that has changed. Most legal Marijuana Grown indoors with some pretty heavy electrical usage to match. Now, researchers have tried to determine the amount of greenhouse gases emitted, and they have come up with some impressive figures. Based on their calculations, more than 2,000 kilograms of carbon dioxide emitted per kilogram of product (defined as dried flowers) resulted in cannabis production, and its legalization had a measurable impact on Colorado’s greenhouse gas production is.

In many places that have legalized cannabis production, a lot of factors make indoor development a reasonable option, including easing safety, enabling year-over-year production, and the only experience that now-professional growers have Years of practice as amateurs. But Colorado – one of the first states to legalize the infrequent-taboo – said the majority of cannabis currently put up for sale should be grown on the site, which is necessarily an accidental inducement. You can either use good agricultural land to develop it, or you can sell it near urban centers and campuses where demand is high – but not both.

Everyone knows that anecdotally Cannabis Cheers rising through electricity. But the only figures we have on actual usage come from pre-legalization days. So Hailey Summers, Evan Sporle, and Jason Quinn at Colorado State, decided to provide some up-to-date figures.

To do this, they obtained hourly data on both the weather conditions and the carbon intensity of emissions for the entire United States. These were fed into a model, which used them to estimate carbon emissions due to the air conditioning needs of cannabis production. The model also took into account all other methods that resulted in indoor production carbon emissionFrom fertilizer manufacturing to disposal of plant waste, and this included emissions associated with the transport of these materials. Overall, the model was used to detect emissions associated with production in more than 1,000 different locations within the US.

The big unknown in all of this is the frequency at which air is run out in the growing facility. Reported rates range from 12 times an hour to 60 times from a complete replacement of the facility’s air. The team offers figures across the range but mostly figures at 20 turnovers / hours.

Finally, electric use was the primary driver of greenhouse gas emissions, as you would expect. But there were some unexpected twists in the details.

For example, the highest electricity consumption is in the southeast of the US, where dehumidifiers and air conditioning were most needed. Jacksonville, Florida, for example, adds humidity management to about 1,500 kilograms of emissions per kilogram of product. Cold weather, like Alaska and Chicago, provides heating through natural gas, and therefore the amount of renewable energy on the grid is no less important – but not insignificant, given the heavy lighting requirement for indoor development. Despite the same emissions as Jacksonville, it comes from heating and cooling needs far beyond moisture management.

Unlike traditional agriculture, fertilizer use is not a major factor in overall greenhouse gas emissions. Many hemp growers, however, increase carbon dioxide levels in the growing room, which can help plants grow faster under the right conditions. Typically, it is the product of other processes, such as the production of carbon dioxide ammonia, and if it was not used in this way, it would be released into the atmosphere as waste. But carbon emissions are still associated with composting and shipping cannabis, so it contributes to about 500 kilograms of emissions per kilogram of product.
