The first thing that you need to do, is set
aside a suitable place for growing. This is actually a large portion of the
obstacles you'll need to overcome.
Hopefully you'll size the room according to how much
light you'll be supplying.
Yes you can have many lights in one room. You'll also need ventilation and
exhaust. Besides ventilation and exhaust, you should plan on air cooling your
light. At the very least, a glass shield helps alot. No glass shield or air
cooling is a recipe for disaster.
Besides exhausting your grow room, you'll need some intakes for fresh air to be
bought in from outside the room.
If you are using a 6" exhaust, you want double that on intake
There are several mathematical formulas floating around
for properly sizing your exhaust.
More is always better. The sole purpose of an exhaust
is not to only expel the heat, but also to replenish the depleted co2 in the
room.
You'll also need an oscillating fan in the grow room. It will take some experimentation on your part to find
out what combination of fans works best.
On the note of experimentation, and opinions for that
matter, you'll find growers to be very opinionated people.
We love to experiment, and we all believe our way is the only way. This is so
false it's not even funny. There are 1000's of ways to successfully grow the plant. Remember it is a weed
after all.
If the advice one grower gives you, does not feel comfortable, or does not fit
your growing style, seek out some more advice.
This, on the surface would seem so basic, and often taken for granted. It shouldn’t be though, they are very important to healthy root growth. Every pot you use should have proper drainage holes in the bottom, if they do not, make some holes in the bottom for drainage.
The other important factor here is size. Start small, and plan on transplanting about every two weeks during the vegging stage.
You can start off in something simple, like a 12 or 16 oz plastic cup, not a transparent cup though, it has to be colored. A transparent grow pot will allow light in, and get at the roots. Roots will not grow well in a lighted condition. Roots and light are just plain bad.
Alot of growers feel strongly about using
square grow pots. Square pots allow for better use of your space,
whereas round grow pots, would waste space, that would be best used by
your roots.
The next step is to gather your growing things. What do we all need if we’re
going to grow cannabis? Pots to put soil in, which should
not pose any major
problems. By soil I mean an earth mix, of course, and in this you have a huge
range to choose from. Cheap bags
of earth as sold in many gardening centers will
work, but can pose many problems for the beginner. The earth contains little
nutrient
and is not airy enough. Well aerated soil is important for good
development of the roots of our cannabis plant. By ensuring you have
a well
aerated soil the plant will grow more vigorously, be stronger, more healthy –
just better all round. You can achieve this by adding small, white, light stones
called perlite to your earth, which make it airier.
Now it has to be said that cannabis plants will pretty much grow on anything;
after all it is and remains a weed.
But try and indulge the plant as much as
possible and she will indulge you in return come harvest time with a
large
yield. So make your way over to the local grow shop if you can. The biggest
advantage of using good
quality earth is that you have nothing or very little to
do. So you do not need to add extra nutrients, for example.
Try to get a decent
organic soil from your local gardening center, add about 35% to 40% perlite to
this soil and
you’ll have a decent base to start with. This recipe can always be improved upon, it is merely a starting point, that will work. However, you could add some domolite lime, bat guano, bone meal, blood meal, the list goes on and on. Try a good organic soil available from your local nursery, along with the necessary pearlite, and whatever else listed above, that you may decide to add into your soil.


We have filled out pots with earth, so what do we need now? Well obviously,
growing marijuana without the cannabis plants
themselves can be a little
difficult. The easiest way to get hold of some, is from seeds. These can be sold
in most countries
and you can order them without any problems.
I can hear the next question on your lips: what sort should I raise? And why are
some seeds so expensive and others cheap?
The simplest way to explain this is
that it is similar to the difference between branded clothes and unbranded.
Branded clothing
costs much more but is not necessarily better. The major part
of the price you pay is going on the brand itself, and the same goes in the seed
world, where the well-known names command the highest prices. It also has to do
with the image; ‘expensive’ is
associated with being ‘better’.
One company sells its seeds for more expensive prices but sells fewer than the
seed company which sells its wares for cheaper
prices. Also, the amount of work
put into a seed’s development and that of new varieties (basically, R&D), adds
to the price.
Through many years’ experience the quality of the seed is kept
high, as with big companies such as Sensi Seeds, and the asking price is high as
a consequence.
But the eventual price depends on many, many factors and my own experience is
that price is not necessarily an indicator of quality.
You can have good and bad
experiences with expensive and cheap seeds.
Even seeds picked out of your weed can be raised into decent plants. But we
still haven’t got our seeds, so which will we plump for?
There is way too much
choice, I must say. Each variety has its own qualities in growing. So the good
news is you can’t really make
a wrong choice. So don’t work yourself up into a
lather choosing. But to make it easier for you: go for an Indica variety. Why an Indica? You have two basic sorts of cannabis plant: Indicas and Sativas.
Indicas don’t grow too large and have a short bloom period, with strong, broad
stems and wide leaves. The Sativas are the opposite, with a strong growth
leading to large plants with thin leaves, and especially during flowering, are
much bigger than the Indicas.
You also have hybrids of the two that are
primarily Indica with a little Sativa, or they can be mostly Sativa with a dash
of Indica
in them. Both sorts are outstanding but for a beginner there is a
greater chance of success with an Indica. Sativas can be
unpredictable and
during flowering can triple in size.
Indica varieties will double their size at most during flowering, which is way
less (especially when space is limited).
Indicas are therefore easier to deal
with and do not hold as many surprises in store, as well as having greater
resistance
to stress (with less for the grower in turn). Definitely for the
grower with just a few plants in a cupboard I recommend the Indicas. Now I don’t
want to give the impression that a Sativa is hard to raise, but if you want to
maximise you chances
of a successful harvest you have got to go for an Indica.
You will notice that there are a lot of these to choose from.
Everyone has a personal opinion on what variety you should go for, so choose for
yourself, as it is ultimately down to
personal preference.
So finally, after much ohh-ing and ah-ing, you’ve made a choice. Nice one!
Once again, you'll find countless methods for germinating seeds.
Here
are some:
(1) I use a paper plate, a moist paper towel, laid on the plate, and folded
half over the seeds, and I slide the whole thing into
a zip lock baggie, than I
blow into the baggie just before zipping it shut. This way as the moisture
evaporates, it is re-distributed
back over the paper towel.
I place the whole thing into a drawer, next to my stove, it's kept warm there.
48 hours later they are ready for planting.
After germination the sprout is placed tap root down with the little bean head
about 1/4 inch deep.
Every other day for the first two weeks they get some superthrive mixed at 3
drops/gal water. Superthrive is not a nutrient but a combination of hormones and
vitamins that primarily stimulates root growth.
(2) I throw my seeds in a shot glass filled with water, let them sit for 12-24
hour. then throw them in pre soaked peat pellets,
under a humidity dome for
4days to a week before roots show.
(3) Take a cup, put some water in the cup and drop the seeds in. Place in a
WARM place and check for the taproot periodically.
(4) Wet paper towel. Fold and put inside tupperware. Place in warm area (like
on top of light) wrap in black plastic first.
Something should be said on cleanliness, and being sanitary when handling
seeds, wash your hands thoroughly first, and handle as little as possible,
especially when making the transfer from the paper towel into it's first new
home.
Marijuana is naturally a high light requirement plant. While there are
alternatives, this is the plants natural desire, to bathe in lumens.
To fill that need, growers typically use HID lighting, because it meets the
demands of the plant.
HID (High Intensity Discharge) Lamps are:
- Efficient. They put out more light, with less energy usage, than any other type
of illumination available to indoor growers.
- Bright. HID's produce more light than other types of indoor horticultural
lighting.
- Expensive. HID's cost more than flourescents. They range in price from $50-$600
dollars.
- Hot. HID's produce heat and precautions have to be taken.
Fluorescent lamps are:
- Inexpensive. Shoplight fixtures can be purchased for as little as $7. Compact
fluorescent bulbs only cost a couple of dollars
a piece.
- Locally Available. Most discount stores and home improvement stores carry
inexpensive, fluorescent fixtures and bulbs.
- Fine for vegetative growth. Fluorescent bulbs put out plenty of light for plants
growing vegetatively, including mothers,
seedlings and clones. Some growers
prefer fluorescents for vegetative growth because of the slower pace of growth
and better
root development.
- Fluorescents need to be in close proximity to achieve their rated output, which
means their canopy penetration is more
limited than HID's.
- Comparatively inefficient. 10 forty watt fluorescent bulbs use the same amount
of energy as a 400 watt HID, but produce far less light.
Since they use the same
amount of energy but produce less light, the remaining must be given off as
heat. Contrary to how it may
first appear, fluoros actually run hotter than the
equivalent wattage of HID-- they just disperse the heat quicker, because it is
spread
over a wider area.
Rough coverage guidelines for HID lights:
400 watts = 3x3
600 watts = 4x4
1000 watts = 5x5
Typically a grower would use a MH light for vegging, and an HPS light for
flowering. These offer the best color spectrum, for
the associated stage of
growth.
Rules are made to be broken though, HPS light bulbs have improved, and growers
are learning you can veg & flower using
an hps, or veg using cfl's and save some
money on your electricity, than flower with their HPS light..
(MH=metal halide light HPS=high pressure sodium)
How many lights/watts can I safely put on a 15 Amp service?
The rule of thumb is to only load a breaker up to 80% of its rated capacity. On a
15-amp service with 14/2 gauge wire one
should only load it up to 12 Amps MAX.
Since most lights will draw 1 amp per 100 watts a 15-amp breaker can handle one
1K light each. This brings up another point in home growing. That it is always
good practice to have the fans and the light that
they cool on the same breaker.
That way if the breaker is somehow tripped (Murphy's Law) then both the light
and its cooling
system are down. Instead of the cooling system for the light
going down and the light still blazes away because it was on another
breaker.
Note: above figures are estimated based on 110V supply.
Vegetative growth is the second stage in the life of a plant after it completes
germination and begins photosynthesis. During this stage
a plant will be photosynthesising as much as possible to grow as large as it can before the
onset of the flowering phase. In essence it
is the period of growth between
germination and the beginning of sexual maturity characterised by flowering.
All plants have a vegetative stage where they are growing as fast as possible.
It is almost standard practice to grow Cannabis plants
with no dark period, and
increase the speed at which they grow appreciably. Plants can be grown vegetatively indefinitely
(Mother Plants for clones). It is up to the gardener
to decide when to force the plant to flower.
Again, there are many ways to accomplish this. The basics of vegetative
growth is to grow
your plant, until it reaches sexual maturity.
There are 2 features that distinguish mature veggie plants from immature ones.
They are alternating nodal arrangement and leaves
with 5 or more blades. You can
flower before those features are present, but the plants perform a whole lot
better if you wait.
Most strains except for equ. sats have these by 12" or so.
Personally, mine have always had these features before they reach 30 days old.
There are other factors to consider too, most indoor growers veg for about 4
weeks. Sometimes more, sometimes less.
Alot of indoor growers like growing an Indica strain. These will about double in
size when you switch to flowering cycle.
A Sativa, will grow about 3 times it's size, during flowering.
These factors, all need to be taken into consideration, along with the size
of your grow room, and the light that you are using.
The main difference between vegetative growth and flowering is the light cycle. 18
hours of light (or more) and 6 hours of
complete darkness tells the plant it is
in vegging state. (Some people veg using a 24 hour light cycle). A 12/12 light
cycle,
tells the plant to flower. It is important to maintain complete darkness
during flowering
Some members input:
Soil:
If I am doing clones (99.9% of the time) I use RapidRooters or rockwool...
I then plant those into a mixture of 60% Foxfarm Ocean Forest and 40% perlite
in the largest styrofoam cups i can find with a
good drainage hole in the
bottom. Under the t-5s they go for 24/0 fun. Wham Bam Thank you Ma'am with LOTS of
light is the key. When the roots start to
wrap in the styro cup.....I up pot
into a 1 gallon and finish the veg to my desired height. A week before flower
I transplant
to a 2-3 gallon and then flip em to 12/12.
Hydro:
Clones in rapids or rockwool...or aero if you have a bubbler or
bucket...when you have ample roots coming out of the cube...into hydroton...run
24/0 lights and drip...backing the drip off to 15 minutes per hour after 1
day/the hydroton is all wet.
General guidelines:
Proper lighting is very important in VEG. Low light will cause spindly/tall
plants that are hesitant to branch out. This is often
amplified if you are
growing sativas/sat hybrids.
Ample lighting AND ventilation will result in bushy/branching plants with
healthy root systems. t-5 or Halide @ 25 watts
per sq ft or higher is
optimal/the best bet for bushy growth in veg. CFL is also favorable for
smaller numbers of plants or
for side lighting. Side lighting will increase
the chance the plant will fill/bush out sufficiently to take cuts or offer
multiple bud sites.
Temps in veg should never exceed 85F. 65-75 is optimal.
IMO.
Always monitor NITROGEN levels in veg. The higher the temp of the room the
LOWER the N should be in the mix.
High temps/high N will also cause
spindly/tall plants with lengthy internodal spacing. If temps are cool in the
room and
light levels are high the plant will take in more nitrogen and use it
for dense/bushy growth.
Beneficial microbes and mycorrihzae innoculants are also very important in
early veg. These products can be apllied early
on in the veg cycle in an
attempt to boost ROOT MASS. The larger the root mass the healthier/larger/more
productive the plant will be.
I use a 4 foot shoplight with 2 40 watt cool white flo's. I also have a
17 watt fish tank flo and a reptile flo im not sure
what the wattage is. I
also have a 150 watt hps that im using right now but thats only cause i dont
have any plants in flower
at the moment. I like to tie my plants down to let
the sides grow out. I usually let them go until they are about a foot tall
before
putting them into flower. I also cut the top cola off so the sides can
catch up to the top. I just topped 2 of my plants yesterday
and i'm trying to
clone them by sticking them in water. I dont have any root gel or nutes
besides some miracle grow but i dont like
using it. I basically germ the seed
throw it in dirt and water it.
