About C4 USA

The Cat City Cannabis Campus is a next-generation indoor cultivation facility designed for scale, efficiency, and consistency. Our operation deploys custom automated production workflows that significantly reduce labor dependency, addressing one of the largest cost drivers in cannabis production while maintaining premium quality standards.
​
Within a fully controlled indoor environment, we utilize advanced energy-efficient technologies and dynamic microclimate controls to fine-tune cultivation conditions on a room-by-room basis. This precision allows us to maximize photosynthesis, plant health, and resin development while minimizing common indoor challenges such as pests, pathogens, and environmental stress.
​
Our process consistently delivers AAA-grade flower and clean-testing, medical-quality botanicals with repeatable results at commercial scale.
​
​
Our cultivation platform is supported by:
​
  • Full-spectrum LED and HPS lighting systems
  • Optimized airflow and oxygenation
  • Precision temperature and humidity control through high-efficiency chiller systems
  • Automated, data-driven nutrient delivery
​
Each system is designed to work in harmony to drive efficiency, sustainability, and predictable outcomes, ensuring our partners receive premium cannabis with consistency run after run.
