Taking the time and doing what it takes to delight our customers

At GreenSeal, consistency is about achieving the highest quality standards possible while maintaining a steady and reliable supply for our customers.

A perpetual weekly harvest schedule, our perfectly balanced indoor environments, the custom lighting systems installed throughout our grow rooms, and personal inspections at multiple quality control checkpoints all contribute to our consistent, high-quality supply.


GreenSeal’s tiered grow rooms are one of the highest-yielding cannabis production spaces per square foot in the world.
