How to Grow Marijuana
Marijuana Growing Tips
for Beginners
Introduction
Growing marijuana indoors is fast becoming an American
pasttime. The reasons are varied. With the increased interest
and experimentation in house plant cultivation, it was
inevitable that people would apply their knowledge of plant
care to growing marijuana. Many of those who occasionally like
to light up a joint may find it difficult to locate a source or
are hesitant to deal with a perhaps unsavory element of society
in procuring their grass.
There is, of course, the criminal aspect of buying or
selling grass; Growing marijuana is just as illegal as buying,
selling, or smoking it, but growing is something you can do in
the privacy of your own home without having to deal with
someone you don't know or trust. The best reason for growing
your own is the enjoyment you will get out of watching those
tiny little seeds you picked out of you stash sprout and become
some of the most lovely and lush of all house plants.

Anyone Can Do It
Even if you haven't had any prior experience with growing
plants in you home, you can have a successful crop of marijuana
by following the simple directions in this pamphlet. If you
have had problems in the past with marijuana cultivation, you
may find the solutions in the following chapters. Growing a
marijuana plant involves four basic steps:
1. Get the seeds. If you don't already have
some, you can buy some good quality marijuana seeds from a
seedshop or, you can ask your friends to save you seeds out of
any good grass they may come across. You'll find that lots of
people already have a seed collection of some sort and are
willing to part with a few prime seeds in exchange for some of
the finished product.
2. Germinate the
seeds. You can simply drop a seed into moist soil,
but by germinating the seeds first you can be sure that the
seed will indeed produce a plant. To germinate seeds, place a
group of them between about six moist paper towels, or in the
pores of a moist sponge. Leave the towels or sponge moist but
not soaking wet. Some seeds will germinate in 24 hours while
others may take several days or even a week.
3. Plant the sprouts. As soon as a seed
cracks open and begins to sprout, place it on some moist soil
and sprinkle a little soil over the top of it.
4. Supply the plants with light.
Flourescent lights are the best. Hang the lights with two
inches of the soil and after the plants appear above the
ground, continue to keep the lights with two inches of the
plants. It is as easy as that. If you follow those four steps
you will grow a marijuana plant. To ensure prime quality and
the highest yield in the shortest time period, however, a few
details are necessary.

Soil
Your prime concern, after choosing high quality seeds, is
the soil. Use the best soil you can get. Scrimping on the soil
doesn't pay off in the long run. If you use unsterilized soil
you will almost certainly find parasites in it, probably after
it is too late to transplant your marijuana. You can find
excellent soil for sale at your local plant shop or nursery,
K-Mart, Wal-Mart, and even some grocery stores. The soil you
use should have these properties for the best possible
results:
 |
It should drain well. That is, it should have some
sand in it and also some sponge rock or
pearlite |
 |
The pH should be between 6.5 and 7.5 since
marijuana does not do well in acidic soil. High
acidity in soil encourages the plant to be
predominantly male, an undesirable trait. |
 |
The soil should also contain humus for retaining
moisture and nutrients |
If you want to make your own soil mixture, you can use this
recipe: Mix two parts moss with one part sand and one part
pearlite or sponge rock to each four gallons of soil. Test your
soil for pH with litmus paper or with a soil testing kit
available at most plant stores.
To raise the pH of the soil, add 1/2 lb. lime to 1 cubic
foot of soil to raise the pH one point. If you absolutely
insist on using dirt you dug up from your driveway, you must
sterilize it by baking it in your oven for about an hour at 250
degrees.
Be sure to moisten it thoroughly first and also prepare
yourself for a rapid evacuation of your kitchen because that
hot soil is going to stink. Now add to the mixture about one
tablespoon of fertilizer (like Rapid-Gro) per gallon of soil
and blend it in thoroughly. Better yet, just skip the whole
process and spend a couple bucks on some soil.

Containers
After you have prepared your soil, you will have to come up
with some kind of container to plant in. The container should
be sterilized as well, especially if they have been used
previously for growing other plants. The size of the container
has a great deal to do with the rate of growth and overall size
of the plant. You should plan on transplanting your plant not
more than one time, since the process of transplanting can be a
shock to the plant and it will have to undergo a recovery
period in which growth is slowed or even stopped for a short
while.
The first container you use should be no larger than six
inches in diameter and can be made of clay or plastic. To
transplant, simply prepare the larger pot by filling it with
soil and scooping out a little hole about the size of the
smaller pot that the plant is in. Turn the plant upside down,
pot and all, and tap the rim of the pot sharply on a counter or
the edge of the sink. The soil and root ball should come out of
the pot cleanly with the soil retaining the shape of the pot
and with no disturbances to the root ball.
Another method that can bypass the transplanting problem is
using a Jiffy-Pot. Jiffy pots are made of compressed peat moss
and can be planted right into moist soil where they decompose
and allow the passage of the root system through their walls.
The second container should have a volume of at least three
gallons. Marijuana doesn't like to have its roots bound or
cramped for space, so always be sure that the container you use
will be deep enough for your plant's root system. It is very
difficult to transplant a five-foot marijuana tree, so plan
ahead. It is going to get bigger.
The small plants should be ready to transplant into their
permanent homes in about two weeks. Keep a close watch on them
after the first week or so and avoid root binding at all costs
since the plants never seem to do as well once they have been
stunted by the cramping of their roots.

Fertilizer
Marijuana likes lots of food, but you can do damage to the
plants if you are too zealous. Some fertilizers can burn a
plant and damage its roots if used in to high a concentration.
Most commercial soil will have enough nutrients in it to
sustain the plant for about three weeks of growth so you don't
need to worry about feeding your plant until the end of the
third week. The most important thing to remember is to
introduce the fertilizer concentration to the plant
gradually.
Start with a fairly diluted fertilizer solution and
gradually increase the dosage. There are several good marijuana
fertilizers on the commercial market, two of which are
Rapid-Gro and Eco-Grow. Rapid-Gro has had widespread use in
marijuana cultivation and is available in most parts of the
United States.
Eco-Grow is also especially good for marijuana since it
contains an ingredient that keeps the soil from becoming acid.
Most fertilizers cause a ph change in the soil. Adding
fertilizer to the soil almost always results in a more acidic
pH.
As time goes on, the amount of salts produced by the
breakdown of fertilizers in the soil causes the soil to become
increasingly acidic and eventually the concentration of these
salts in the soil will stunt the plant and cause browning out
of the foliage. Also, as the plant gets older its roots become
less effective in bringing food to the leaves. To avoid the
accumulation of these salts in your soil and to ensure that
your plant is getting all of the food it needs you can begin
leaf feeding your plant at the age of about 1.5 months.
Dissolve the fertilizer in worm water and spray the mixture
directly onto the foliage. The leaves absorb the fertilizer
into their veins. If you want to continue to put fertilizer
into the soil as well as leaf feeding, be sure not to overdose
your plants.
Remember to increase the amount of food your plant receives
gradually. Marijuana seems to be able to take as much
fertilizer as you want to give it as long as it is introduced
over a period of time. During the first three months or so,
fertilize your plants every few days. As the rate of foliage
growth slows down in the plant's preparation for blooming and
seed production, the fertilizer intake of the plant should be
slowed down as well. Never fertilize the plant just before you
are going to harvest it since the fertilizer will encourage
foliage production and slow down resin production.
A word here about the most organic of fertilizers: worm
castings. As you may know, worms are raised commercially for
sale to gardeners. The breeders put the worms in organic
compost mixtures and while the worms are reproducing they eat
the organic matter and expel some of the best marijuana food
around. After the worms have eaten all the organic matter in
the compost, they are removed and sold and the remains are then
sold as worm castings.
These castings are so rich that you can grow marijuana in
straight worm castings. This isn't really necessary however,
and it is somewhat impractical since the castings are very
expensive. If you can afford them you can, however, blend them
in with your soil and they will make a very good organic
fertilizer.

Light
Without light, the plants cannot grow. In the countries in
which marijuana grows best, the sun is the source of light. The
amount of light and the length of the growing season in these
countries results in huge tree-like plants.
In most parts of North America, however, the sun is not
generally intense enough for long enough periods of time to
produce the same size and quality of plants that grow with ease
in Latin America and other tropical countries. The answer to
the problem of lack of sun, especially in the winter months,
shortness of the growing season, and other problems is to grow
indoor under simulated conditions. The rule of thumb seems to
be the more light, the better. In one experiment we know of,
eight eight-foot VHO Gro-Lux fixtures were used over eight
plants.
The plants grew at an astonishing rate. The lights had to be
raised every day. There are many types of artificial light and
all of them do different things to your plants. The common
incandescent light bulb emits some of the frequencies of light
the plant can use, but it also emits a high percentage of far
red and infra-red light which cause the plant to concentrate
its growth on the stem. This results in the plant stretching
toward the light bulb until it becomes so tall and spindly that
it just weakly topples over. There are several brands of bulb
type.
One is the incandescent plant spot light which emits higher
amounts of red and blue light than the common light bulb. It is
an improvement, but has it drawbacks. It is hot, for example
and cannot be placed close to the plants. Consequently, the
plant has to stretch upwards again and is in danger of becoming
elongated and falling over. The red bands of light seem to
encourage stem growth which is not desirable in growing
marijuana. The idea is to encourage foliage growth for obvious
reasons. Gro-Lux lights are probably the most common
flourescent plant lights.
In our experience with them, they have proven themselves to
be extremely effective. They range in size from one to eight
feet in length so you can set up a growing room in a closet or
a warehouse. There are two types of Gro-Lux lights: The
standard and the wide spectrum. They can be used in conjunction
with on another, but the wide spectrum lights are not
sufficient on their own.
The wide spectrum lights were designed as a supplementary
light source and are cheaper than the standard lights. Wide
spectrum lights emit the same bands of light as the standard
but the standard emit higher concentrations of red and blue
bands that the plants need to grow. The wide spectrum lights
also emit infra-red, the effect of which on stem growth we have
already discussed. If you are planning to grow on a large
scale, you might be interested to know that the regular
flourescent lamps and fixtures, the type that are used in
commercial lighting, work well when used along with standard
Gro- Lux lights. These commercial lights are called cool
whites, and are the cheapest of the flourescent lights we have
mentioned. They emit as much blue light as the Gro-Lux
standards and the blue light is what the plants use in foliage
growth.
Now we come to the question of intensity. Both the standard
and wide spectrum lamps come in three intensities: regular
output, high output and very high output. You can grow a nice
crop of plants under the regular output lamps and probably be
quite satisfied with our results. The difference in using the
HO or VHO lamps is the time it takes to grow a crop. Under a
VHO lamp, the plants grow at a rate that is about three times
the rate at which they grow under the standard lamps.
People have been known to get a plant that is four feet tall
in two months under one of these lights. Under the VHO lights,
one may have to raise the lights every day which means a growth
rate of ate least two inches a day. The only drawback is the
expense of the VHO lamps and fixtures.The VHO lamps and
fixtures are almost twice the price of the standard. If you are
interested in our opinion, they are well worth it. Now that you
have your lights up, you might be curious about the amount of
light to give you plants per day.
The maturation date of your plants is dependent on how much
light they receive per day. The longer the dark period per day,
the sooner the plant will bloom. Generally speaking, the less
dark per day the better during the first six months of the
plant's life. The older the plant is before it blooms and goes
to seed, the better the grass will be. After the plant is
allowed to bloom, its metabolic rate is slowed so that the
plant's quality does not increase with the age at the same rate
it did before it bloomed.
The idea, then, is to let the plant get as old as possible
before allowing it to mature so that the potency will be a high
as possible at the time of harvest. One relatively sure way to
keep your plants from blooming until you are ready for them is
to leave the lights on all the time. Occasionally a plant will
go ahead and bloom anyway, but it is the exception rather than
the rule. If your plants receive 12 hours of light per day they
will probably mature in 2 to 2.5 months.
If they get 16 hours of light per day they will probably be
blooming in 3.5 to 4 months. With 18 hours of light per day,
they will flower in 4.5 to 5 months. Its a good idea to put
your lights on a timer to ensure that the amount of light
received each day remains constant. A "vacation" timer,
normally used to make it look like you are home while you are
away, works nicely and can be found at most hardware or
discount stores.

Temperature and
Humidity
The ideal temperature for the light hours is 68 to 78
degrees fahrenheit and for the dark hours there should be about
a 15 degree drop in temperature. The growing room should be
relatively dry if possible. What you want is a resinous coating
on the leaves and to get the plant to do this, you must
convince it that it needs the resinous coating on its leaves to
protect itself from drying out. In an extremely humid room, the
plants develop wide leaves and do not produce as much
resin.
You must take care not to let the temperature in a dry room
become too hot, however, since the plant cannot assimilate
water fast enough through its roots and its foliage will begin
to brown out.
Back
to top
Ventilation
Proper ventilation in your growing room is fairly important.
The more plants you have in one room, the more important good
ventilation becomes. Plants breathe through their leaves. The
also rid themselves of poisons through their leaves. If proper
ventilation is not maintained, the pores of the leaves will
become clogged and the leaves will die. If there is a free
movement of air, the poisons can evaporate off the leaves and
the plant can breathe and remain healthy.
In a small closet where there are only a few plants you can
probably create enough air circulation just by opening the door
to look at them. Although it is possible to grow healthy
looking plants in poorly ventilated rooms, they would be larger
and healthier if they had a fresh supply of air coming in. If
you spend a lot of time in your growing room, your plants will
grow better because they will be using the carbon dioxide that
you are exhaling around them.
It is sometimes quite difficult to get a fresh supply of air
in to your growing room because your room is usually hidden
away in a secret corner of your house, possibly in the attic or
basement. In this case, a fan will create some movement of air.
It will also stimulate your plants into growing a healthier and
sturdier stalk. Often times in an indoor environment, the stems
of plants fail to become rigid because they don't have to cope
with elements of wind and rain. To a degree, though, this is an
advantage because the plant puts most of its energy into
producing leaves and resin instead of stems.

Dehumidifying Your Growing
Room
Cannabis that grows in a hot, dry climate will have narrower
leaves than cannabis grown in a humid atmosphere. The reason is
that in a dry atmosphere the plant can respirate easier because
the moisture on the leaves evaporates faster. In a humid
atmosphere, the moisture cannot evaporate as fast.
Consequently, the leaves have to be broader with more
surface area in order to expel the wastes that the plant put
out. Since the broad leaves produce less resin per leaf than
the narrow there will be more resin in an ounce of narrow
leaves than in one ounce of broad leaves. There may be more
leaf mass in the broader leafed plants, but most people are
growing their own for quality rather than quantity.
Since the resin in the marijuana plant serves the purpose of
keeping the leaves from drying out, there is more apt to be a
lot of resin produced in a dry room than in a humid one. In the
Sears catalog, dehumidifiers cost around USD100.00 and are
therefore a bit impractical for the "hobby grower."

Watering
If you live near a clear mountain stream, you can skip this
bit on the quality of water. Most of us are supplied water by
the city and some cities add more chemicals to the water than
others. They all add chlorine, however, in varying quantities.
Humans over the years have learned to either get rid of it
somehow or to live with it, but your marijuana plants won't
have time to acquire a taste for it so you had better see that
they don't have to.
Chlorine will evaporate if you let the water stand for 24
hours in an open container. Letting the water stand for a day
or two will serve a dual purpose: The water will come to room
temperature during that period of time and you can avoid the
nasty shock your plants sufferwhen you drench them with cold
water. Always water with room temperature to lukewarm water. If
your water has an excessive amount of chlorine in it, you may
want to get some anti- chlorine drops at the local fish or pet
store. The most important thing about watering is to do it
thoroughly. You can water a plant in a three gallon container
with as much as three quarts of water.
The idea is to get the soil evenly moist all the way to the
bottom of the pot. If you use a little water, even if you do it
often, it seeps just a short way down into the soil and any
roots below the moist soil will start to turn upwards toward
the water. The second most important thing about watering is to
see to it that the pot has good drainage. There should be some
holes in the bottom so that any excess water will run out.
If the pot won't drain, the excess water will accumulate in
a pocket and rot the roots of the plant or simply make the soil
sour or mildew. The soil, as we said earlier, must allow the
water to drain evenly through it and must not become hard or
packed. If you have made sure that the soil contains sand and
pearlite, you shouldn't have drainage problems.
To discover when to water, feel the soil with your finger.
if you feel moisture in the soil, you can wait a day or two to
water. The soil near the top of the pot is always drier than
the soil further down. You can drown your plant just as easily
as you can let it get too dry and it is more likely to survive
a dry spell than it is to survive a torrential flood. Water the
plants well when you water and don't water them at all when
they don't need it.
Back

Bugs
If you can avoid getting bugs in the first place you will be
much better off. Once your plants become infested you will
prob-ably be fighting bugs for the rest of your plants' lives.
To avoid bugs be sure to use sterilized soil and containers and
don't bring other plants from outside into your growing
room.
If you have bets, ensure that they stay out of your growing
room, since they can bring in pests on their fur. Examine your
plants regularly for signs of insects, spots, holes in the
leaves, browning of the tips of the leaves, and droopy
branches.
If you find that somehow in spite of all your precautions
you have a plant room full of bugs, you'll have to spray your
plants with some kind of insecticide. You'll want to use
something that will kill the bugs and not you. Spider mites are
probably the bug that will do the most damage to the marijuana
plants. One of the reasons is that they are almost microscopic
and very hard to spot. They are called spider mites because
they leave a web-like substance clinging to the leaves. They
also cause tiny little spots to appear on the leaves. Probably
the first thing you'll notice, however, is that your plants
look sick and depressed.
The mites suck enzymes from the leaves and as a result the
leaves lose some of their green color and glossiness. Sometimes
the leaves look like they have some kid of fungus on them. The
eggs are very tiny black dots. You might be wise to get a
magnifying glass so that you can really scrutinize your plants
closely. Be sure to examine the underside of the leaves
too.
The mites will often be found clinging to the underside as
well as the top of the leaves. The sooner you start fighting
the bugs, the easier it will be to get rid of them. For killing
spider mites on marijuana, one of the best insecticides if
"Fruit and Berry" spray made by llers.
Ortho also produces several insecticides that will kill
mites. The ingredients to look for are Kelthane and Malatheon.
Both of these poisons are lethal to humans and pets as well as
bugs, but they both detoxify in about ten days so you can
safely smoke the grass ten days after spraying. Fruit and Berry
will only kill the adult mite, however, and you'll have to
spray every four days for about two weeks to be sure that you
have killed all the adults before they have had a chance to lay
eggs.
Keep a close watch on your plants because it only takes one
egg laying adult to re- infest your plants and chances are that
one or two will escape your barrage of insecticides. If you see
little bugs flying around your plants, they are probably white
flies.The adults are immune to almost all the commercial
insecticides except Fruit and Berry which will not kill the
eggs or larva. It is the larval stage of this insect that does
the most damage. They suck out enzymes too, and kill your
plants if they go unchecked. You will have to get on a spraying
program just as was explained in the spider mite section.
An organic method of bug control is using soap suds. Put
Ivory flakes in some lukewarm water and work up the suds into a
lather. Then put the suds over the plant. The obvious
disadvantage is it you don't rinse the soap off the plant
you'll taste the soap when you smoke the leaves.
Back
to top
Pruning
We have found that pruning is not always necessary. The
reason one does it in the first place is to encourage secondary
growth and to allow light to reach the immature leaves. Some
strands of grass just naturally grow thick and bushy and if
they are not clipped the sap moves in an uninterrupted flow
right to the top of the plant where it produces flowers that
are thick with resin.
On the other hand, if your plants appear tall and spindly
for their age at three weeks, they probably require a little
trimming to ensure a nice full leafy plant. At three weeks of
age your plant should have at least two sets of branches or
four leaf clusters and a top.
To prune the plant, simply slice the top off just about the
place where two branches oppose each other. Use a razor blade
in a straight cut. If you want to, you can root the top in some
water and when the roots appear, plant the top in moist soil
and it should grow into another plant. If you are going to root
the top you should cut the end again, this time with a diagonal
cut so as to expose more surface to the water or rooting
solution.
The advantage to taking cuttings from your plant is that it
produces more tops. The tops have the resin, and that's the
name of the game. Every time you cut off a top, the plant seeds
out two more top branches at the base of the existing branches.
Pruning also encourages the branches underneath to grow faster
than they normally would without the top having been cut.

Harvesting and
Curing
Well, now that you've grown your marijuana, you will want to
cur it right so that it smokes clean and won't bite. You can
avoid that "homegrown" taste of chlorophyll that sometimes
makes one's fillings taste like they might be dissolving. We
know of several methods of curing the marijuana so that it will
have a mild flavor and a mellow rather than harsh smoke.
First, pull the plant up roots and all and hang it upside
down for 24 hours. Then put each plant in a paper grocery bag
with the top open for three or four days or until the leaves
feel dry to the touch. Now strip the leaves off the stem and
put them in a glass jar with a lid. Don't pack the leaves in
tightly, you want air to reach all the leaves.
The main danger in the curing process is mold. If the leaves
are too damp when you put them into the jar, they will mold and
since the mold will destroy the resins, mold will ruin your
marijuana. you should check the jars every day by smelling them
and if you smell an acrid aroma, take the weed out of the jar
and spread it out on newspaper so that it can dry quickly.
Another method is to uproot the plants and hang them upside
down.
You get some burlap bags damp and slip them up over the
plants. Keep the bags damp and leave them in the sun for at
least a week. Now put the plants in a paper bag for a few days
until the weed is dry enough to smoke. Like many fine things in
life, marijuana mellows out with age. The aging process tends
to remove the chlorophyll taste.
