Applications

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

Indoor Cannabis Flowering

High-yield strains in an optimized environment should be grown with 4’x4’ per Mult-HI 720, at least 6 inches above the crop, whether single or multi-tier. Lower intensity approaches, such as grow rooms without CO2 enrichment, should utilize 5’x5’ Mult-HI 720 spacing at least 15 inches above the crop or 4’x4’ Mult-HI 480 spacing at least 6 inches up.

Indoor Cannabis Vegetative

4’x4’ per Mult-HI 480 is excellent. For a lower intensity approach, 5’x5’ Mult-HI 480 spacing or 4’x4’ Mult-HI 340 spacing is a quality, moderate approach especially appropriate for shorter veg cycles.

Low-Height, High-Intensity Applications

Mult-HI lights can also be used when high intensities are needed with minimal overhead space with which to work, e.g. tall, high-light crops on greenhouse benches.

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.

Dustin Johnson
Owner/Operator, High Ground Farms

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.
