From Marijuana Growers Handbook by Ed Rosenthal-Horticulturists have reported a number of methods for increas- ing
plant yeilds which are still in the experimental stage. These in-
clude stimulating growth using an electrical current, the use of
estrogen and progestin, and the use of strobe lighting.
ELECTRICITY
Experiments at the University of Maryland indicate that a very weak
electrical current running through the soil increases the growth
rates of plants. This stimulation seems to be most effective when
the plants are not receiving a lower than optimum level of light.
Some researchers speculate that the current increases the roots'
efficiency in obtaining nutrients by affecting the chemical-
electrical charges of the nutrient dissolved in the water. One com-
pany manufactures a photovoltaic device specifically to charge the
soil. The magazine Mother Earth News reported in the March 1984
issue that plant growth can be doubled using these devices. ""Sun
Stiks" are available from Silicon Sensors, Highway 18 East,
Dodgeville, Wisconsin 53533.
FEMALE HORMONES - BIRTH CONTROL PILLS
Over the years there have been a lot of anecdotal reports in-
dicating that birth control pills stimulate plant growth. In 1983, a
farmer in Texas reported that his tomato plants grew many more
tomatoes after they received two treatments with estrogen-based
pills. There may be a problem of safety regarding the use of these
hormones. There have been no studies on what happens to the hor-
mone once it is taken up by the plant. When estrogen is given to
farm animals, it increases their growth rate, but the meat contains
traces of the substance, which sometimes affects people who eat it.
STROBE LIGHTS
Some botanists have speculated that the pigments which are us- ed in
photosynthesis respond to energy peaks in the light wave. These
scientists believe that much of the light is wasted by the plant
because it isn't "peak". They speculate that much energy could be
saved by supplying the plant only with light "peaks". One way to do
this is by using a strobe unit in place of conventional lighting.
The strobe flashes a high intensity of light, but it is on for only
frac- tions of a second. The result is that the plants receive many
light peaks in between periods of darkness. There has been little
research on this theory, but one grower claimed to get satisfactory
results. One way to use a strobe without too much risk might be to
use it to supplement more conventional lighting. If a higher growth
rate is noticed, the strobes could be tried alone. Should this
system work, electrical costs could be lowered by as much as 75%.
