The first build
Grower Pro Series Greenhouse: affordability without cutting corners.
Our basic greenhouse frame skips the premium options (which can all be added as upgrades down the road), without compromising on strength, ease of build, or usefulness on the farm.
A starting point, not a box: width, length, height, end walls, and climate control all configure to your operation.
Pre-drilled frame
Farmer-owned
Climate control
Fans & vents included
Heat & automation optional
Top covering
Double-inflated 6-mil
Inflated for insulation
Make it yours
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.
