hello and welcome to the Migro YouTube channel my name is Shane and I'm the
founder of Migro today we're going to look at the effects of different colored
light on plant growth we've got three different grow bays set up and we've got
three different light spectrums and we're going to test the growth rates and
the characteristics of the growth of the different plants under different colors
of light what we've done is we've set up each of the grow bays with three three
different colors of light red blue and full-spectrum white light
and we've set up so that the power levels that canopy level are exactly the
same so the amount of power and micro moles per meter squared per second has
been adjusted for each Grove a so that a plant canopy level there's 500 an
average of 500 micro moles per meter square per second in each Bay this will
give us the opportunity to look at the productivity rates as well as the
characteristics of the growth so how much flowering internodal and all those
different characteristics under exactly the same light conditions in terms of
intensity the difference being the wavelengths of light are colors of light
that the plants are being exposed to so let's look at the set up in each of the
different grow bays we've got a different light source on the left-hand
side the full spectrum of white light we've got the micro 100 LED which is
drawing 107 watts and as I've said underneath the canopy this level we have
an average of 500 micro moles per meter square per second
in the red bay we've got a Chinese life I'm not sure the branding could be a
messy light I took out the blue LEDs and replaced them with red ones so we've got
all red light here and this one has to be hung quite high it's 190 watts and
producing again 500 micromoles per meter square second of Perak light across the
top of the plant Kathy and in the blue Bay we've got a LED light called a grow
blue and this one is drawing 240 watts it's hung a little bit lower than the
red one in order to achieve the same level of power across the top of the
canopy so let's look at the spectrum for each of the lights so we're going to
test them I go 100 full-spectrum light first we're using the Essenza tech
lighting passport which is a full-spectrum spectrometer and we're
able to use the agricultural app alongside to test and record and view
the spectrum from each of the grow lights so as I said the micro is
full-spectrum much to the Cree the red light is peaking at 6:30 and 660
nano meters and the blue light is peaking at 442 for 60 nanometers the
each of the grow phase has been planted with the same plants at the rear we've
got lettuce which has been grown from seed up to about 10 days old and under
full-spectrum light so they're juvenile plants and we're gonna see how they
respond to the different colors of light we may get different productivity we may
get different characteristics such as number of leaves internal distance
and color different characteristics like that we've got three bedding plants or
flowering pants so we're going to see how many blooms
what sort of productivity each of the plants have for flowering under each of
the light spectrums so everything is set up now we're ready to run the growing
experiment we're going to be running it over the next couple of weeks until we
can see good results from both the lettuce and the bedding plants in terms
of flowering and productivity and they'll be interesting to see at this
exactly the same power level which color of light produces the best growth and
what characteristics that growth has so keep tuned please subscribe and take
care
