How to Use a Lux Meter to Increase Your
Cannabis Yield
Light is very important in determining the overall health and performance of the plant. Alongside
air ow, space, and availability of nutrients, lightning is pivotal if the grower intends to get
maximum yield from the cultivation process. It is then important to ensure that the plant and grow
area has access to an adequate amount of light regardless of the grow technique, outdoors or
indoors.
The importance of adequate lighting to the success of a grow operation makes the knowledge of
how to measure the amount of light the plant is getting a huge advantage. This doesn't just ensure
that the cultivation process is properly modulated, it greatly improves the probability for success.
The equipment used for this immensely valuable process is the lux meter and in here I'll explain
deeply what it is, it's bene ts, etc.
What is a Lux Meter?
A lux meter is an electronic device that is used to measure the amount of light in lumen per meter
squared in the grow room area. The unit of measurement of the lux meter can also be simply
referred to as lux. A lux meter is a simple tool that is very bene cial to every grower and helps in
the perfection of the cultivation process to maximize yield.
Quantum meters and PAR meters are used by professionals to determine the amount of
photosynthetically active radiation that is available for the plant to photosynthesize. These meters
are more sensitive than lux meters however they have a major downside with respect to cost.
Unlike lux meters which are relatively cheap and could go for as little as 20 pounds, PAR meters
are relatively expensive as they go for as high as 1000 pounds. For a grower, a lux meter easily

meets the needs that it is required to cater to as it accurately measures the amount of visible light
in the growing area which provides the grower with the information needed to interpret the health
of the plant.
Bene ts of a Lux Meter
A lux meter is very bene cial to the growing process as it helps a grower perfect the cultivation
process in several ways. A couple of the bene ts of a lux meter include:
Increase in yield: With the knowledge of the amount of light entering the grow area, the grower is
equipped with important information that helps him/her ensure the cultivation process is properly
done. The use of the lux meter allows the grower to known the perfect spots in the grow area with
an optimum amount of light needed to sustain and promote growth. It also allows the grower to
know the blind spots of the grow room that is not getting enough light. This helps the grower to
ensure that the plants all get equal access to light which in turn increase and maximizes the yield
of the produce.
Prevention of plant health problems: With the knowledge of the amount of light reaching the
grow area, the grower is equipped enough to protect the plant from health problems arising from
too much light or less than the amount of light needed for sustainability. When the cannabis plant
in your grow area is exposed to too much light, the plant is likely to su er from a light burn or
bleaching which frustrates the growing process while when less than adequate light reaches the
plant it is unable to actively photosynthesize and can show growth defects. Therefore, the use of
the lux meter helps the grower to protect the plant from such health problems.
More e cient than the eyes: Many growers are used to physically assessing and determining the
amount of light that is reaching the grow area especially when using white lights indoors. Lux
meters however are more e ective and e cient than the physical eyes in assessing the amount of
light as they help to determine the distance to the source of light that a ords the grower the
chance to optimize the amount of light reaching the plant.
Helps to replace HID grow lights: Lux meters help to determine when HID grow lights which have
de nite lifespan begin to grow dimmer and allows the grower to know when they need to be
replaced.
It is also important that a grower knows the amount of light that is optimal for cannabis clones or
seedlings, for the vegetative plant as well as the owering plant.
Readings within the range of 5000-7000 lux are suitable for clones or seedlings.
15000-50000 lux are perfect for vegetative cannabis plants
while a range of 45000-65000 is suitable for the owering plant.

The maximum amount of light that the cannabis plant for work with is 75000 lux as lux meter
readings of 85000 lux and above are already too much and are bound to promote light stress and
bleaching in the plant.
It is also important that the readings of the lux meter are properly done by the grower to ensure
accurate readings. Di erent readings should be taken at di erent parts of the grow room and at
the varying heights of the plant canopy for de nite results.

Does Cannabis Help with Hydrocephalus?
People suffering from hydrocephalus often have seizures as a side-effect. There is already a long list of positive outcomes where
CBD is shown to be very effective in treating and reducing seizures. Both THC and CBD have anti-in ammatory properties and
would be helpful to reduce in ammation in the brain. Both are also found to be effective in the treatment of nausea and vomiting.

MEDICAL
Is There Any Medicinal Value in the Roots of Cannabis Plants?
When cannabis roots were used many years ago, the complexity of modern medicine was not that much at play. More studies have
to be done to see how it interacts with some medication, just like it is done with THC and CBD. Other than that, cannabis root shows
a great potential to be used in alternative treatment.
