Classify Your Product With
Environment, Product, Process
Environment, product, and process (EPP) are the three core characteristics used in product classification.
Environment refers to how the five essential inputs — light, temperature and humidity, carbon dioxide, and water — are provided to fuel plant growth.
Product refers to the type of product that a material is.
Process refers to the post-harvest processing method used to finish a product.
​
Each characteristic has several categories with a corresponding unique identifying code. When combined, they create 252 unique plant material product codes.

Environment
Greenhouse
Greenhouses are enclosed structures that utilize the sun as a light source but are contained environments that allow for many of the same controls as an indoor garden.
​
Hoophouse
Hoop houses are outdoor-grown plants covered with hoops that support a layer of plastic sheeting that diffuses or blocks light. Hoop houses are often utilized for light deprivation, a technique that allows cultivators to manipulate light patterns and harvest multiple crops a year outside the typical growing season.
​​
Indoor
Indoor facilities are highly controlled and customizable growing environments that rely on artificial lighting for plant growth.​
Outdoor
Outdoor refers to plants grown under the full sun in the traditional growing season. Outdoor plants are grown directly in the ground or in raised beds or pots.
