As we all know, plants use light to transform water and carbon dioxide into glycogen. However, not all wavelengths are equally efficient or as important. For instance, we know that red, blue, and far-red are the most efficient wavelengths, but they also have their individual response in growth in the different stages of the whole growth cycle. Yet, plants can only use a certain amount of light. Therefore, we have to be cautious on desolating energy by supplying too much light to a plant since that could turn into a huge waste.

How to increase energy efficiency?
There are two dimensions to increasing energy efficiency when choosing LED lighting solutions. The first is on the crop level, mainly determining the optimal spectrum and intensity for your crops in the different plant life stages. The other is the engineering part. When knowing which spectra to use, the exact light solution and growth area must be designed to utilize the power that's put into the system in the best way possible.

How do you tackle the increasing costs?
Chose a high-quality/highly efficient LED providing a minimum of 3,3 umol/s/watt.
Operate them as cold as possible – but do not waste energy on cooling.
Fit the led with optics/reflectors and lenses to direct the photons in the direction you want them.
(Move the light as close to the crop as possible) reduce loss
Secure a uniform light level at the entire growth area - this normally means many LEDs.
Make the growth area reflective – so the plants get more than one chance to catch the photons.

How to save on costs massively?
Firstly, know the spectra and intensity your plants can absorb throughout their life cycle. Secondly, only use highly efficient LEDs to create the wanted light schedule. Thirdly, design an optimal growing field – to best utilize the energy you put into the system, as 30% cost savings on energy consumption is a good ambition.

HortiBest's Octopus-H8 720W LED grow light has a full spectrum FSG offer photon emission across the PAR 400-700nm wavelength range to cover the full-cycle growth of most indoor plants and vegetables. It is a great choice to save on energy costs.
