Grower Replaces T5s Fluorescents with VividGro's GroBar™ Luminaires, Gains Dramatic Savings in Time and Expense

"If you have not seen a GroBar™ yet, you have not seen one of the best lights to hit the growing industry," says John Minor, owner and operator of TURBO POTS. The first automated aeroponic growing system, TURBO POTS delivers nutrient saturation through short injections of light fluid nutrients, water and air through the soil. On a mission to create a cutting-edge indoor growing environment, Minor worked to identify optimal lighting for the cloning stage of his crop. "I'm always looking for ways to be innovative, I don't care about how it's been done in the past. When I understood the potential of GroBars, it was a no-brainer," he continued.

On the list of GroBar benefits, cool bulb temperature was key, according to Minor. Heat-emitting bulbs, like the T5, must be mounted to prevent close proximity to the crop. Plants that unexpectedly exceed the estimated height can come into contact with lighting fixtures, causing damage. Because GroBar luminaires are completely cool, plants can come into direct contact without incurring any damage. Growers then have greater flexibility in stacked grow options and see an additional benefit in reduced cooling costs.

Minor has also noticed other benefits that make a difference, saying, "Because of the mounting configuration, GroBars are easy to clean. It takes ten minutes to disassemble, wipe down and reassemble a T5 bank. It takes seconds to wipe down GroBars." He has also noticed a significant difference in durability and longevity: whereas T5 bulbs can break during installation and require frequent replacement of the bulbs or repair to the ballast, GroBars are made of plastic, surviving drops and installation for longer use. With an internal driver, expenses and lost time related to ballast repairs and replacements are a thing of the past.

"The output of the GroBars also impressed me: one GroBar does the work of two T5s and draws less power," says Minor. Let's do the math on that. T5 bulbs draw 54 W each, while GroBars draw 30 W and you need half the amount of them." So:


T5 at 54 W

per bulb

GroBar at 30 W

per bulb


4-Bulb Fixture

216 W

60 W

GroBar = 96 W less

8-Bulb Fixture

432 W

120 W

GroBar = 192 W less

12-Bulb Fixture

648 W

360 W

GroBar = 288 W less

But what are the savings in dollars and cents? Well:




WV, TX, OR, NC, NV, 


AL, CO, DE, GA, IL, IN, 



T5 4-bulb

fixture, 216 W




GroBar 2-bulb 
fixture, 60W




Savings per hour




Savings in one 
day (10 hours)




"To me, the savings in utility costs alone make the choice pretty clear. Add to that the lifespan of three years, compared to a T5s needing replacement every six months. It really is a no-brainer."

Minor is on a mission to bring awareness to his fellow growers, saying, "In my perspective, the GroBar lives up to its name – it IS the coolest light in cannabis, both in temperature and features. We currently have replaced all our T5 fixtures with GroBarsand will never look back. When I show somebody the GroBar, their mouth drops. If you're looking to update or create a new grow room, before you spend your money on any other light, you must check out the GroBar first."
