Narrator: Canadian winters can be long and dark.
[Cut to a shot of a snow covered forest.]
This lack of year-round natural light impedes greenhouse production...
[Cut to a different shot of snow falling and trees in the background.]
...during the winter months.
As a result...
[Cut to an up close shot of snow covered glass and a greenhouse in the background]
...greenhouse growers need to use supplementary lighting to provide the high quality produce...
[Cut to a pan shot of cucumbers, orange peppers and red peppers with a human hand grabbing a red pepper.]
...that consumers want year-round.
[Continued pan shot of red peppers.]
But not all light is created equal...
[Cut to a pan shot of vegetable crops.]
...and crops develop and grow differently when they are supplied with alternative light sources.
[Cut to a different shot that pans upwards towards a light source]
Greenhouses currently use High Pressure Sodium, or HPS lights.

They have a low capital cost, but you can’t adjust the quality of the light.
[Shot of light source hanging from the ceiling directed towards the crops with animated white heat waves]
And they can get very hot – up to 300 degrees - which means that plants could burn if the lights are too close.
[Shot of AAFC researcher, Dr. Xiuming Hao holding up a Light Emitting Diodes, or LED lights]
Light Emitting Diodes, or LED lights...
[Cut to a close-up shot of the LED lights.]
...are a new state-of-the-art technology.
[Cut to different shot of the vegetable crops lit up by blue and red LED lights.]
They provide higher quality light...
[Cut to a different shot of pink LED lights hanging from the ceiling pointed towards the crops.]
...with customizable intensity, direction...
[Cut to a close up shot of the 3 dials on the LED light control panel written beneath these dials are Red, White and Blue with a switch that has an illustration of an eye and of a leaf.]
...and colour settings.
[Cut to a shot of fuchsia LED light hanging inside of a crop canopy]
They also have a lower surface temperature than HPS lights...
[Cut to a different shot of the hanging fuchsia LED light facing an unripen tomato.]
...so they can be used right inside the crop canopy.

Agriculture and Agri-Food Canada is one of the leading organizations...
[Cut to a close-up of the green cucumber Dr. Xiuming Hao is examining.]
...in the world in the study of vertical lighting distribution for greenhouses.
[Cut to a shot of Red LED lights inside a tomato crop.]
The results show that this new system can improve...
[Cut to a different shot of a blue LED light inside of a tomato canopy.]
...the yield and nutritional value of greenhouse crops.
[Cut to a shot of the greenhouse crops, a text box slides into to view form the top of the screen.]

They’ve found that by using an optimized hybrid lighting system...

[The text boxes disappear and the previous crop canopy image remains.]
...mini-cucumber plants yield twice as many vegetables as they would in a traditional greenhouse. Twenty times more than they would in the field!
[Cut to a close-up shot of a green bell pepper being pricked by a scientific instrument.]
They’re also studying the effect of different coloured LED lights...
[Cut to a different shot of Dr. Rong Cao analyzing data on a computer screen.]
...on the production of antioxidants in greenhouse vegetables.
[Cut to a close-up shot of Blue LED lights inside a tomato crop canopy.]
Blue lights increase polyphenols that help plants to protect themselves from insects and disease.
[Cut to a close-up shot of Red LED lights inside of a tomato crop canopy.]
Red lights, on the other hand, increase carotenoids and are very good for plant growth and leaf health.
[Cut to a different shot of two men walking down a pathway with crops on either side inside of a greenhouse.]
The results of these studies may allow Canada’s greenhouse growers to conquer Canadian winters and move to full 12-month production cycles.
[Cut to a close-up shot of an individual cutting with a knife a red bell pepper off of a greenhouse crop.]
This will allow them to produce fresh vegetables throughout the winter months...

...meeting consumer demands for high quality, local produce year round.

It will also allow them to be more competitive because they will be able to edge out...

[Cut to a different shot of the cargo ship sailing at sea with many containers on board.]
...will be able to expand their presence on the international market.
[Cut to a shot of Dr. Xiuming Hao and a woman examining a vine of a tomato plant.]
With the help of our Canadian agricultural scientists...
[Cut to a close-up of the tomatoes being examined.]
...the sun will never stop shining on Canadian greenhouse growers.
[Cut to a pan shot of the rows of crops in a greenhouse.]
And in the right light, at the right time, everything is extraordinary.
