Every build starts from your farm.

Grower, Grower Plus, and Grower Pro are options, not fixed models; every kit we sell is customized to the crops, climate, and specific needs of the farm it is part of.

Heat & climate

Add heaters, inflation fans, and thermostats to hold temperature through the coldest months.

Ventilation & automation

Roll up sides are standard on every kit, but you can upgrade to automatic motors or add a ridge vent or powered exhaust fans for more control.

End walls & glazing

Framed end walls, doors sized for carts or tractors, and double-poly glazing.
