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
