Cannabis plants grow in the clone room at Aurora Deutschland GmbH, a manufacturer of medical Cannabis products, in Leuna, Germany September 11, 2023.
But some companies are trying to combat that like U.K.-based cultivator Glass Pharms.
It claims to be the world's first firm to grow cannabis indoors in a carbon-neutral way.
That is then used to heat and cool Glass Pharms' greenhouse.
This means Glass Pharms' greenhouse facility does not take any electricity from the energy grid, nor does it rely on mains water.
