Ornamentals & Floriculture
Grow lighting for ornamentals generally accomplishes one of two purposes:
(1) Increase growth rates and quality, especially rooting and/or cut flower production with high intensity lighting, or
(2) Simulate long days to control the timing of flowering for day length sensitive crops with low intensity photoperiodic lighting.
For high intensity lighting to enhance growth rates and quality, generally target around 70 µmol*m-2*s-1, or about 100/160 sq ft of coverage per TG33B/TG53B High Intensity Top-Light, approx 6-11 ft above the canopy depending on the setup. Cut flowers may use up to double this intensity, and lower intensities can be used for lesser but lower cost improvements.
For low intensity photoperiodic lighting, the most common solution is Pure Flowering 200 Lamps on 14'x14' centers approx. 8-10' above the crop. See Greenhouse - Photoperiodic Lighting for more. Contact us for recommendations specific to your application.
Bedding plant propagation
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.

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.

Boom lighting for flower intiation
The Night & Day bulbs are the perfect boom lights. I no longer waste time replacing burnt out bulbs or worrying about when a light failure will delay my production. The plants look great, and the costs are tiny for the area covered! I like knowing that all of the energy from the TotalGrow bulbs goes into the light plants need most, not wasted for human eye light.

Mum flowering control tests
TotalGrow™ Night & Day Management Light bulbs were very effective at controlling flowering times across a large collection of my mum varieties this fall. The lights will allow me to greatly reduce my power consumption compared to my existing HPS lights with better plant quality.

Wave petunia flower initiation
We have been extremely pleased with our Night & Day Management Lights. In addition to improving growth speeds and flowering times of our wave petunias, the uniformity of coverage, durability, and lower utility and installation costs of the lights are excellent.
Greg Nowak, Owner
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
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.

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.
