High quality lighting during the first few weeks of a plant's growth provides the greatest impact on many critical qualities, especially rooting. A very high value is added per light due to the concentration of plants.
Generally target around 50 µmol*m-2*s-1, or about 50 sq ft per TG15A fixture of coverage (ideally 5-7 ft fixture heights). Contact us for recommendations specific to your application.
A new technique to trigger the prioritization of rooting in plugs has demonstrated profound success in limited testing. 16W TG1B Pure Flowering 200 Lamps, which have improved upon the former generation of Night & Day Management Light bulbs covering 100 sq ft each have been successfully used to trigger rooting in as little as 1/3 of the time with daylength extension lighting.

Hops propagation, 7'x10' fixture spacing
We found that installing the TotalGrow™ light system has improved our plant quality and sped up our operations, which allows us to do more cycle turns and expand our business without putting up more greenhouse space.

Bedding plant propagation, 143W TotalGrow vs. 400+W HPS test
TotalGrow™ lights demonstrated the potential for drastic energy savings over HPS lights while producing crops of equal or better quality in our bedding plant testing. With 20% less PAR light intensity, our primrose plugs grew over 33% wider and taller with better green pigmentation than HPS.

Bedding plant propagation, 10'x11' Night & Day bulb spacing
We discovered that we can drastically reduce rooting times with TotalGrow™ Night & Day Management Lights for fuchsia, petunia, calibrachoa, verbena, bacopa and other crops – as little as 1/3 of the time compared to even high intensity HPS lighting with up to 98% power savings! We are also amazed by the coverage uniformity, utility savings and electrical infrastructure savings.

Lettuce & herb propagation shelves, 15"x12" Grow bulb spacing
We are also starting our seedlings with TotalGrow lights, and that has been really spectacular in the growth that we’re getting with those compared to the T5 fluorescent lights that we had been using. The plants are much heavier weights and much denser growth compared to the fluorescent lights. It’s been very impressive for us and we’re excited to change everything over.

Orchid propagation, 6'x8' fixture spacing
In a controlled experiment, our Vanda seedlings grew larger and stronger than seedlings grown under natural light. In some instances as much as 40% increase in mass was observed. The additional growth was most evident in the increased root mass of the seedlings grown under TotalGrow™ light, perhaps as a result of the photosynthetic ability of orchid roots. Based on our experience at Motes Orchids, I can recommend TotalGrow™ lights to any grower as a benefit under low light conditions.

Propagation & photoperiodic lighting, 9'x14' fixture spacing
I hesitate to turn on my HID lights due to the energy costs, but I don’t think twice about turning on my TotalGrow lights due to their efficiency and longevity.

Perennials propagation, HPS replacement test with 1/3 power
We completed growing tests using the Venntis Technologies TotalGrow™ light fixtures. We tested several varieties of perennials and our results showed similar plant vigor and health while reducing our energy consumption.

Adams Greenhouse & Produce, LLC:
Lettuce, kale, cabbage, broccoli, etc., 6'x12' fixtures
The lights are fantastic!!! We have seen a great improvement by having the lights. The plants are so much farther ahead of schedule than we had anticipated. They are growing great and we have not had a problem with them. The plants are not stretching for light and have thick stems and are growing nice and straight.
