Every application is unique, and our lighting experts will gladly provide you with a detailed, custom light plan based on your crops, location, facility, utility incentives, budget, and other factors. General approaches include:

Confined-Space Greenhouse Supplemental Lighting

Smaller grow spaces, lower overhead heights, and/or less intense lighting demands make higher output lights problematic. Mid-power Mezzo lights, typically with around 6’ spacing and 4’ heights, become the perfect solution.

Vertical Grow Racks

Mezzo lights can be utilized in indoor, vertical grow setups with relatively higher lighting needs or larger spaces. For example, lettuce at 2’x4’ per light, 16” heights.


Side-mounting/suspending Mezzo lights illuminates deeper levels of large plants. If high intensities of top lighting for high-light plants like tomatoes or cannabis is already provided, side or interlighting can provide additional growth. Mezzos can be suspended back-to-back within plant rows or along the edges of grow areas for tall crop setups.

What our customers say

One Partner In My Cannabis Facility Build that Went Smoothly

TotalGrow Lights is extremely knowledgeable and easy to work with. A lot of other companies you're dealing with one of their retailers or one of their wholesalers, with TotalGrow you're dealing with the lighting experts of the company directly. It just makes transactions a lot easier and a lot more accurate as far as ship times and delivery times. I never really even had to do anything; they handled it all. They are one partner in my cannabis facility build that went very smoothly and how I wanted it to. I will definitely work with them in the future.

Five Year Warranty Standard - Couldn’t Ask For Anything More

The customer service is one of the best I’ve ever dealt with. They are to the point, never leave you hanging, call to make sure you received the shipment and everything is working. Also they have a five year warranty standard, that’s the extended warranty with other companies. Saving me that much more money because it’s standard, which makes you realize they have something special. I couldn’t ask for anything more than all that.

Extremely Pleased With Both Lights & Customer Service

TotalGrow Lights is just so easy to work and collaborate with from planning, ordering, and shipping. They are very good about being responsive and giving good technical background and information, on their website and talking with them, more information than most other grow light companies. Everything ordered came in well and seems very well made. I am extremely pleased with both the lights and customer service.

Helped Me Incorporate My Existing Lighting

TotalGrow is pretty seamless to work with, better than almost any company I've ever worked with. Their expertise starts in guiding you through the lighting plan development. They don't miss anything. They even helped me with incorporating my existing lighting, which wasn't their product. Honestly, probably the best lighting support I've ever dealt with. I definitely wish more companies could compare to their customer service.
