GrowPros Solutions Viper Model 4 Under Canopy Deep Red LED Grow Light - 2 Pack

Struggling with underdeveloped lower buds and slow flowering transitions? The GrowPros Solutions Viper Under Canopy Light Model 4 Dual Channel is the commercial-grade solution designed to eliminate "larf" and accelerate your harvest cycle by up to 2 weeks. By targeting the areas your top-down lights can't reach, this system ensures every part of your plant produces premium, harvestable flower.

This revolutionary lighting solution features a strategic dual-channel spectrum configuration. The primary channel delivers a Full Spectrum + Red + White mix for optimal flower development, while a dedicated, independent Infrared (730nm) channel triggers the Emerson Effect. This allows growers to stimulate a faster hormone switch at the beginning of the dark cycle, leading to earlier harvests and increased annual production cycles. Note: An inter-connect cable (sold separately) is required to daisy-chain multiple units.

FAQs

What is the Emerson Effect?+

The Emerson Effect is a physiological response in plants where the rate of photosynthesis increases significantly when exposed to both long-wave red (Infrared) and shorter-wave red light. The Viper Model 4 uses a dedicated 730nm channel to trigger this, shortening the vegetative-to-flowering transition by up to 2 weeks.

Can I daisy chain these lights?+

Yes, you can daisy chain multiple units using the Growpros Solutions Inter-connect Cable. This allows you to power and control multiple fixtures from a single source for cleaner cable management.

Do I need special stands for installation?+

We recommend using the Under Canopy Light Stands to ensure your fixtures are positioned at the optimal height to reach the lower canopy without obstructing airflow or maintenance.

Is the infrared channel independent?+

Yes, the Viper Model 4 features a dual-channel design. When used with a compatible controller like the GrowPros Environment Controller, you can manage the main spectrum and the infrared channel on separate schedules for maximum plant manipulation.

What power cord options are available?+

These lights are compatible with various power setups. You can choose from 240V power cords or standard 120V options to match your facility's electrical infrastructure.
