Case Study

Tanana Herb Company

Overview

  • Sam Hachey, principal of Tanana Herb Company in Fairbanks, Alaska
  • Operating since Alaska legal market began (Aug 2016)
  • Currently sells between 8 and 10 pounds a week
  • Developing a new shop expected to double sales

This is a great fixture we can expand with that provides a nice even canopy. The plants love the spectrum and we love a low operational cost.

Problem

  • Had been using an “industry norm” setup:
    • High pressure sodium/metal halide lights in bloom rooms
    • T5s (florescent lamps 5/8” in diameter) in veg rooms (early growth, pre-bloom)
  • The setup used a lot of power, threw off too much heat, and didn’t provide good canopy coverage
  • Plants were languishing in the shade
  • Tested other light varieties and brands with lukewarm results

Solution

  • Set up VividGro GroBars in Tanana’s veg rooms
    • Positioned over a 4’ x 8’ bed, three fixtures per foot, fixed to the ceiling
  • The outcome is an excellent choice —a nice even canopy that the plants flourish under
  • This new setup keeps the nodes close together without any need for PGRs (plant growth regulators)
  • The benefits are “minimal power drawn, excellent canopy coverage and little to no heat”
  • VividGro saves 30% on power compared to NextLight

Why GroBar Works

  • 5000 K spectrum is ideal for growing young plants vegetatively without stretching them
  • Light field on the plant canopy is very uniform with no “hot spots”

Case Study

Home Grower

Overview

  • Rodger X., independent grower
  • Home growing for six years to provide relief for his wife, who has a serious nerve injury
  • Allowed by state law to raise 12 plants at a time for his wife’s personal use

These lights cover the tent completely and are handsdown the best I have ever used.

Problem

  • Had been using an Amare 450 LED panel with UVB in a tent that could only hold twelve plants if some of them were in the corners
  • This setup limited output to six plants at a time even though permitted to produce twice that because plants in the corners floundered in the shadows
  • The Amare system used chips-on-board LEDs (COBs) that created a lot of heat and made it necessary to run an intake fan consistently

Solution

  • Set up VividGro GroBars in growing tent
  • Gained full, consistent coverage on every plant in the tent, increasing yield by growing the full quota of 12 plants at once
  • Yielded more than 1.5 grams dry weight per Watt on the first try, with even more expected next cycle
  • “It’s a great light,” he says. “It illuminates my entire grow tent. Not just a light footprint in the middle with a little bit of light on the sides. A solid footprint.”

Why GroBar Works

  • 4000 K spectrum is ideal for growing autoflower plants throughout the life cycle
  • Light field on the plant canopy is very uniform with no “hot spots”
