Tantalus Labs is a marijuana cultivator dedicated to pioneering new, sustainable technologies while maintaining an environmental stewardship. Some even call it the “Tesla of cannabis”. Now, they’re continuing to improve their technologies with their new completely environmentally controlled greenhouse, which is the first of its kind. They call it SunLab, which has taken a total of 4 years to design and construct. SunLab uses non-artificial sunlight to help the plants turn a rich green color while reducing electricity demand by up to 90%. It also uses pure rainwater to feed the plants, and air filtration to prevent stagnant moisture.
