Automation & Light Deprivation Systems
Precision Light Control for Any Greenhouse
T3’s internal blackout systems provide dependable light-cycle management for both small residential greenhouses and full-scale commercial grows. Designed for durability, smooth operation, and full automation integration.
How It Works
Our blackout curtains run on an internal suspension system to keep fabric protected and moving quietly and cleanly. Two drive options are available based on greenhouse size:
Rack & Pinion Drive (Standard for Most T3 Greenhouses)
Gear-driven, synchronized movement
Best for greenhouses 30 ft and longer
Ideal for commercial cannabis/hemp and high-frequency light-dep cycles
Cable-Pull Drive (Best for Small Greenhouses Under 30 ft)
Simple, low-maintenance, cost-effective
Perfect for Bloom Box, backyard growers, and compact structures
