variety of plants, all with favorable results. The
University of Tennessee saw a 20% increase in
yield (root weight) with lavender. The University
of Minnesota experienced increases in yields
with a variety of crops, including 2006 bell
peppers (58% increase), 2006 brandywine
tomatoes (21% increase), 2007 bell peppers
(32% increase), 2007 brandywine tomatoes
(13% increase), 2007 hanging basket flowers
(16% increase), 2013 Strawberries Evie 2
(18.3% increase), and 2013 BHN 589 toma-
toes (15.8% increase). The research institution
testing shows just how beneficial enhanced lev-
els of dissolved oxygen can be for overall yield.
the solution itself and never bring warm air or CO 2 from the
growing space into the root zone.
O 2 Grow Oxygen Generators are also extremely energy
efficient. The units convert AC current to low voltage DC,
with the smallest unit drawing only 6 watts. When it is
considered that the O 2 Grow Oxygen Generator only needs
to operate for a couple of hours per day, it is apparent just
how little electricity they require over the course of a garden
cycle. Remarkably, all of the units can even be run from a
12 volt battery. Most growers connect the O 2 Grow Oxygen
Generator to a cycle timer for automation. However, the
very best approach a marijuana grower can take is to mon-
itor his or her dissolved oxygen content with a dissolved
oxygen meter. The hydroponic nutrient solution will have a
maximum saturation point for dissolved oxygen. Or, in other
words, a point at which the solution cannot hold any more
dissolve oxygen. This is why it would be counterproductive
to operate an O 2 Grow Oxygen Generator 24 hours a day. In
most cases, it only takes an hour or two for the nutrient solu-
tion to reach its maximum dissolved oxygen capacity.
Not Exclusively for Hydroponics
Although hydroponic marijuana growers are sure to be
impressed by the results achieved with an
O 2 Grow Oxygen Generator, they are
not exclusively made for hydroponics. An
O 2 Grow Oxygen Generator can be used
for plants in soil containers as well. Sim-
ply run the O 2 Grow Oxygen Generator
in the watering can or holding reservoir
for an hour or two (depending on volume
and size of emitter) to maximize the
dissolved oxygen content, then water the
plants as usual.
Cannabis growers are always looking for
products or techniques to increase the yields of
their gardens. Most growers understand that by
increasing efficiency, they can automatically increase
yields. O 2 Grow Oxygen Generators not only increase
the efficiency of an indoor marijuana garden, they are
reinventing the way horticulturists deliver oxygen to
the plant’s root systems. By using a dissolved oxygen
meter to test the nutrient solution’s dissolved oxygen
content, marijuana growers can witness for themselves
the immense difference an O 2 Grow Oxygen Generator
can make in their gardens. By saturating the nutrient
solution with the highest amount of dissolved oxygen
possible, growers can rest assured that they are provid-
ing the plant’s root systems with everything they need
to maximize nutrient uptake. There is no other product
on the market that enables a grower to increase the
dissolved oxygen content to the levels that an O 2 Grow
Oxygen Generator can produce. Once a cannabis
grower experiences the O 2 Grow Oxygen Generator
difference for themselves, he or she will never go back
to air stones again. PMG
