Although stimulating the Phytochrome PFR can lead to increased oil content, flavour and aroma it not essential to achieve a good quality end result and high yield. However if you combine stimulation of phytochrome PFR and in 720nm - 730nm with photosynthetic stimulation of the red 650nm - 660nm range it is possible to again increase essential oil production in your plants.
As many of you are already aware Infra-Red led can sometimes be somewhat problematic as when driven to the same extremes as you red 660nm led’s it will inevitably overheat and fail, and if your led’s are wired incorrectly this can then lead to thermal runoff that will soon take down the rest of your light engine.
We steered clear of infra-red led’s for quite some time due to these problems and focused primarily on energy production.
Osram however have now produced a horticultural infra-red led to run in-line with the rest of their horticultural led family so it is now included in all G.O.D light engines.
Now we don’t want too much infra-red as this will lead the plant to think it is growing in the shade and therefore make you plants and inter nodal spaces stretch so it has to be carefully managed.
