Excel Farms represents the visionary partnership of two lifelong friends, Terry Leright and Greg Attwood, whose backgrounds in plant irrigation and health and fitness, respectively, converged to inspire a groundbreaking concept. In the midst of their conversations, they identified a gap in the market for a cultivation facility that isn’t just advanced and efficient but also committed to environmental sustainability without compromising on the quality of cannabis flower produced. This shared vision led to the creation of Excel Farms, aiming to set new standards in the cultivation of premium cannabis while maintaining competitive pricing.


Today our purpose is to be cultivators, concentrating on the one thing we do best: grow high-quality cannabis.


Terry has been a Michigan Medical Caregiver for the last 8 years. He is passionate about his style of growing which involves a fully-automated Deep Water Culture system (Current Culture). 


Implementing this expertise, Greg and Terry have taken the caregiver model and upscaled it to a commercial facility.


Excel Farms is an emerging business specializing in high-quality medical and recreational cannabis.

  • Our facility exclusively uses energy-efficient LED lighting to minimize our environmental footprint.
  • By adopting hydroponic cultivation with water-based nutrient solutions, we eliminate the need for traditional growing mediums, thereby reducing waste.
  • We have selected state-of-the-art hydroponic systems from Current Culture to ensure sustainable and efficient plant growth.
  • We utilize an advanced in-house water treatment system to transform well water into purified reverse osmosis (RO) water, ensuring the highest quality for our hydroponic systems.
  • All water generated from condensation within our facility is reclaimed and reused, demonstrating our dedication to water conservation.
  • Our nutrient solution wastewater undergoes a meticulous reclamation and filtration process before being reused, aligning with our sustainability goals.
  • We employ a Thermal Evaporator for wastewater disposal, enabling us to operate as a zero wastewater discharge facility and significantly reduce our environmental impact.
  • Our facility is equipped with water-cooled air conditioners, complemented by a cooling tower, to achieve unparalleled efficiency in climate control.
  • Our commitment to sustainability extends to our water usage; we do not discharge wastewater into the sewer system.



RDWC is a method of growing in a nutrient rich solution of oxygenated water. The plants and roots grow into this recirculating water system. With RDWC, the growth and yield is better and the quality of product is second to none. 


Our Lighting System

Our lighting system uses Gavita which has been on the forefront of cultivator lighting for years. We use the new Gavita 2400e lights throughout the facility. These lights allow us to push the limits of a cultivar when it comes to light intensity.
