In this section you will find detailed information about how to use the HashCropter to reach it's full potential as well as general information about LED lighting in horticulture.
A homogeneous light distribution is crucial in order to optimize yields as well as crop quality. Read more about how to deliberately adapt the light distribution to your setup in this section:
The HashCropter is the world's first LED grow light with the possibility to easily adjust the light distribution by adjusting the arms. Choose between the four positions (see picture).
We strongly recommend to always set all four arms to the same position, unless you use a PAR meter or a spectrometer.
The HashCropter is recommended for grow tents of up to 150x150 cm to ensure an optimal PPFD. The following picture shows the light distribution in the two most recommended grow tent sizes. As we pointed out before a homogenous light distribution is crucial to maximize crop quality and yields. A homogenous light distribution will ensure that every plant will recieve the same amount of light. Otherwise the higher light intensity in the center of the grow tent can lead to stress for the plants in the middle while the plants near the walls will waste energy in order to grow towards the brighter areas.
Light distribution is highly dependent on factors like reflectancy of the walls, geometry of the room and positioning of the plants. Therefore it is not constructive to give general advice. In such cases we highly recommend professional light planning. Please contact us.
To get more detailed information on how to use the touch panel or Control HUB in order to adjust the intensity, read the Dimming/Spectral Tuning section in the HashCropter User Manual.
We recommend a distance of 50 cm between the light sources of the HashCropter and the plant tips. This is crucial in order to ensure optimal distribution and penetration of the light.
It is always recommended to gradually increase the intensity over several days between the growth stages. The duration of each growth stage highly depends on your grow method and strain. The recommended settings for the different growth stages can be found in the following tables:
*This setup is recommended for fast production of cuttings. The Absolute Intensity Mode can be reduced to 2 (120x120) and 3 (150x150) if the production of cuttings is not needed.
WARNING! The following aspects should always be considered:
Please use the following chart (click to enlarge) to manually adjust the light intensity to your needs.
WARNING! We highly recommend to run at least two cultivation periods in order to get used to the HashCropter technology before starting to apply spectral tuning.
For plants light is not only a source of energy! In fact plants are also able to 'detect' and 'interpret' the spectrum. Based on that information a wide range of processes inside the plant can be triggered.
The following summary will give you a brief overview about the impact of the different ranges of the spectrum:
Very important to know/understand is that the different effects of the different ranges of the spectrum do not work independently. In fact the ratio between those different ranges of the spectrum is most important.
Furthermore it is also important to consider that different plants and even different strains react differently to various light treatments. What probably all of you already know is that a plant in its flowering phase also requires a different light treatment as opposed to when it is in the vegetative stage.
For all who don't use our Control HUB we have created an interactive excel tool to give you an indication about the possibilities and the impact of spectral tuning on PPF and efficiency.
