SPECTRUM TUNING
This section will help you in the process of evaluating which
spectrums will be best suited for each stage of plant growth.
Note: All spectrums mentioned wil be in an A/B/C channel
configuration. So a 20/80/80 would be 20% Red (Channel A),
80% Blue (Channel B), and 80% White (Channel C).
Seedlings - Due to the tender nature of seedlings, you will want to tune
your light down quite a bit for this stage of life. Once a seed has broken
the surface, we recommend a break-in period of about a week where the
light will be in the range of 15/30/30. Once the seedling has been above
ground for about a week, the first set of true leaves should be present. At
this point the intensity of the spectrum can be marginally increased. We
suggest a 30/60/60 at this point. Once your plant has two or more true
sets of leaves, you can set your light to the Vegetative spectrum below.
Clones - Clones are a little bit hardier than fresh seedlings, but still need
to be given gentle light as they are completely root-less when first cut, and
need to conserve energy and moisture to transition into a rooting stage.
We have had great success with rooting clones at 25/45/45.
Vegetative - In this stage, the deeper red spectrums are utilized less by
the plant than when it is in flower and uses high levels of blue light that are
essential for creating lush, thick plants that have tight internodal spacing
and very little stretching. This is the same spectrum that will be used for
plants that you don’t want to flower, such as leafy greens, basil, and
mircogreens. For this stage, we recommend using a 30/60/60, 45/80/80,
or 60/100/100 depending on the type of plant and its light use
requirements.
Flowering - At this stage, the plant has a lot of work to do and is
preforming many complex biological processes in producing flowers
and/or fruits. Because of this, the plant now requires large amounts of light
in all categories. For high use plants, we like to run full power with a
100/100/100. For lower light use plants, dialing back all spectrums equally
can achieve the proper amount of light while maintaining proper spectrum.
Late Flower - In this stage most rapid development has stopped and the
plant is gearing up for the stage in which the large flowers and fruits will
mature or ripen. During this stage, the blues can be dialed back to a
100/70/100 in order to mimic those late days of summer and conserve a
little extra power in the process.
