Intermediate Marijuana Grower's Techniques
This is a grower's guide for those folks who already know a thing or two about growing marijuana.
There are several key factors in growing the optimal or near optimal Marijuana plant. These factors can be manipulated to produce different physical variations in any seedstock selected.
THEY ARE:
*01* Light Intensity and Spectrum
*02* Photoperiod
*03* Temperature Cycle
*04* Nutrients
*05* Humidity Cycle
*06* CO2
*07* Pruning
*08* Leeching
*09* Cloning
*10* Stress
Light Intensity And Spectrum
The Light Spectrum should be as close as approximation of natural sunlight as is available. The light intensity should be as bright as is possible while still keeping temperature in line.
In addition to metal halide and high pressure sodium lighting you can experiment with fluorescent lights suspended around the plants. This can improve the yield of buds towards the bottom of the plant.
Photoperiod
During the growth phase (vegetative), the light period should be a minimum of 18 hours per day. The light can be continuous during the growth phase (24 hours per day) with profound effects.
You can try using the light cycle below instead of going straight from 24 hours a day of light to 12 hours. Start this cycle during the vegetative phase, 25 days before you want to start flowering.

During the FLOWERING PHASE, 12 hours of uninterrupted light stimulates the production of budding sites for the flowers. The light is left on 12 hours a day till plants are harvested.
I cannot stress enough that during the FLOWERING PHASE, the dark period should not be violated by any light. It delays flower development and promotes leaf growth. If you must work on the plants during this time, allow only as much light as a VERY pale moon can provide for less than 5 minutes.
Temperature Cycle
The atmospheric temperature in your grow room should be in 70's and 80's for most marijuana strains. However, the closer you get to the ideal temperature range, the better the buds and the less likely you are to get male plants (see stress).
A marijuana strain that originated in a hot climate will require a higher optimal temperature than a strain that originated in a cooler climate. If you are not sure where your seeds originated, you can experiment with temperature to see what effect warmer or cooler temperature will have.
Nutrients

Humidity Cycle
The humidity should be kept high (around 90%) unless you are growing in soil and over watering has occurred, and you need to dry the soil quickly. Marijuana doesn't like its roots to be wet all the time, so don't water every day when growing in soil unless the temperature is quite high. If proper ventilation is maintained, problems like fungus and algae should be minimal.
Average watering solution usage growing in soil:
10 days after transplant--------1 Quart (946 ml)
20 days after transplant--------1.5 Quarts (1419 ml)
30 days after transplant--------2 Quarts (1892 ml)
During Flowering--------------1.5 Quarts (1419 ml)
CO2
Carbon Dioxide (CO2) levels should be high, particularly during the FLOWERING PHASE. Growth rates can be increased dramatically if the CO2 level is near 700 ppm.
300 ppm (Outside Air)
700 ppm (Ideal)
2000 ppm (Plants Burn)
5000 ppm (Death)
CO2 is cheaply produced by burning Natural Gas. However, heat and Carbon Monoxide must be vented to the outside air. CO2 can be obtained by buying or leasing cylinders from local welding supply houses. Beware! The DEA has asked the supply houses to provide lists of large CO2 users. If you are questioned, simply say "I have an old mig welder at the house and I want to try and patch up my (lawnmower, car, trailer, etc.). If you find that you are making lots of trips to the supply house, complain that your "buddy" keeps leaving the cylinder valve open all night. This should provide a plausible excuse.
Pruning
To maintain the optimal growth rate, trim all dead leaves. The more often you trim, the slower the Marijuana plant will grow and the narrower the internodal length. Trimming the growth tip after the plant is 4-5 leaf sets tall will produce a "Y" shaped plant with two "arms". Too much trimming will result in poor growth and often hermaphrodism (having both male and female flowers). Keep pruning to a minimum during the entire FLOWERING PHASE. (see why prune and pruning tips)
Leeching
From time to time, it is beneficial to leach the soil of high concentrations of salts. The salts come from the fertilizer solution by means of evaporation. To leach soil, over water the growing medium until fluid can be seen above the soil line. Allow the swampy mess to soak for a few minutes, then pump/siphon off excess from the "well" at the lower end of the growing area.
To leach a hydroponic garden, drain the reservoir of any existing solution and replace with water that has aged 3 days or longer and don't add nutrient solution. Leave for a day or two and repeat or add regular strength nutrient solution.
Cloning

Stress
Since Marijuana is very responsive to its environment, big changes in any of the growth factors (light, heat, food, water, etc.) can affect not only the growth of the plant but also potency and even sex.
The whole thing is really a trade-off. If you want bigger, faster growing buds, then you could experiment with increased stress. However, too much stress will force hermaphrodism or even a male from a normally female plant.
VOTE OR PERISH!
ATTEND CANDIDATES RALLIES AND ASK IF THEY SUPPORT LEGALIZATION OF MARIJUANA. REMEMBER THEY ACT ON WHAT THEY THINK NICE FOLKS WANT. ASK AND YOU SHALL RECEIVE. IT WORKS.
