In the Netherlands the average yield of tomatoes grown in Greenhouses are around 51kg/m2. In South West Norway we have greenhouse producers producing up to 120kg/m2. This is accomplished through use of heating, supplemental light and CO2 fertilizing in the green houses.
Yes, it's great. But take the Impatiens Geranium graph where he concludes Dawn and Dusk are periods when supplemental light are needed for the Bizzie Lizzie. A producer would be asking can I stack them under low light?
Very interesting study, seems to be able to change the world big time, congratulations! Is there currently any studies known on the relation between photosynthesis efficiency and lightening timing for algae growth?
I have a strange question, I've heard of a theory about growing plants that are photosensitive to the length of darkness they receive determining their veg v bloom life stage... A method to boost veg growth was to put the lights on for 6 hours, then off for 2 hours and back on for 6 etc.. with the idea being that the 2 hours off is enough time to process the 6 hours of work with lights on. Is there some truth to this?
I'm not quite sure but physiologically it makes sense. It depends on the plant of course but photosensitive plants have different periods of time they need _minimum_ to make the switch to their nighttime cycle. So you'd have to take a bunch of measurements depending on your crop to know exactly what cycle to prescribe but theoretically 6 on 2 off would work. The other issue with that approach in large scale ag is that you'd be doing 6 on 2 off into the night when you have to pay for all the supplemental lighting. Photons from the Sun are free and at a large scale providing supplemental photons for _just_ the cycle you described would be terribly cost inefficient.

There are other methods of shortening maturity periods and increasing photosynthesis. Advancing Eco Agriculture uses Sap Analysis to determine which minerals are limiting photosynthesis and then uses a foliar spray to increase the needed lacking nutrients. Others have studied energy. Feeding volcanic rock dust to worms gives us chelated minerals that are paramagnetic. Dr Arden Andersen is an MD and has a PhD in biophysics. He uses volcanic rock dust to grow plants faster inside a greenhouse. I would like to see a greenhouse with good soil. Some magnetized biochar energized with fungal dominant compost. Grow 16 different plants and grasses in a Jena biodiversity experiment that has been proven to grow soil. Add to the mix a CO2 generator to add CO2 to the water which is sprayed onto the leaves of the plant to increase biomass. Grasses to be grown on a living pathway. This should be a climate battery greenhouse to reduce heating and cooling expenses. I have not done this yet.
This deserves a million views. This is so cutting edge that it defines the future of supplemental lighting.

An amazing and useful study!
No nutritional value data between Photoperiod time change ?

Whats the ETR of Cannabis?

I wish I had studied harder and applied myself in college

Watch at 1.5x speed. You're welcome
I liked his chill pace, was able to stay engaged the whole talk
Not really... It may work for you, but that doesnt mean it works for all of us too
Arrogance is key to yellow plants
Great teacher
