Why did Cannerald choose Montel's Vertical Grow Rack System?

“We set quality at the highest point,” said Levin Amweg, co-founder of Cannerald, “so we wanted the same for our equipment.” In each of Cannerald’s two main flower rooms, Montel’s four two-tiered vertical grow racks effectively doubled their growing potential and cut their footprint in half, all while making it easier for growers to care for their plants.


Montel’s GROW&ROLL®8MA heavy-duty mechanical-assist carriages are built bigger and are better equipped to withstand heavier loads than its little brother GREENRAK®.

GROW&ROLL®8MA mobile grow rack systems cuts back space-wasting aisles. With one aisle, you can double your growing capacity with the same square footage without having to move, acquire new land, expand, or build a new facility. Maximize your available space to increase yields, free up room for your grow operation, or get rid of space you don’t need. The key to increasing your yield and profits is optimizing your grow space along both the horizontal and vertical axes, thus maximizing your cubic footage. By using a mobile vertical grow rack system instead of static racking, you avoid lighting empty aisles without crops, thereby optimizing energy consumption. With its engineered gear ratios and high-quality components, GROW&ROLL®8MA is the most durable and smoothest-running mobile grow rack system on the market.


Once you give GROW&ROLL®8MA a spin, you will never want to use other vertical growing equipment.
