Spencer has a love for the marijuana plant and has been growing within the RI medical program (and been a patient himself) for the past 8 years. Mammoth uses recirculating, deep-water culture hydroponics to produce the cleanest and highest quality product while also achieving remarkable turnaround times. This process allows the plants at Mammoth to always have water and nutrients readily available which can be delivered directly to the root system via frothing, highly-oxygenated, reverse-osmosis filtered water.  Agricultural data is constantly monitored with sensors to identify plant eating desires/habits, and all flower is always hung dry and hand trimmed to produce consistent quality and results.  Mammoth understands the importance of having new elite genetics and is constantly hunting through varieties to find new flavors and potent cultivars.
