Marijuana plants or cannabis plants are unlike any other plant on earth. It is the only annual plant that has a very distinct and different male and female. The females produce sweet potent buds with little hairs that protrude from the center of its teardrop shape pistols, the male, on the other hand, produces little pollen sacks that open like a flower releasing the pollen into the air which drifts to the female’s little hairs. These detailed instructions will help you grow marijuana on your own.
Once the male pollen has reached the female’s little hairs the pollen works its way down to the pistol, in turn pollinating the plant. When the female is now pollinated she will stop producing her lovely potent buds and start producing seeds for next year’s offspring.
When growing for medicinal purposes we look to keep just pure females!
When growing medical marijuana for medicine we want to grow our plants to their maximum potency. The way we do this is by:
Buying quality seeds or clones. You can find seed banks online or in the back of “High Times” magazine.
You want to make sure that you have the very best of the crop, assuring that every plant will be a female with the exact yield and potency as the next. The way we do this is by crop selecting. Crop selecting is a process where you sprout your seeds, plant the seeds, grow your plants then weed out all the male and small or week plants. When your down to your last strong big female it’s time to make her a mother plant. Taking cuttings or clones from her insures that your crop will be all females with the exact DNA and potency as your lone female mother. You should have a mother plant for each strain. If it’s a bigger operation you should have multiple mothers for each strain. You can take 13-15 cuttings every 3 weeks from a single mother plant for up to 3 years if left under 18 hrs of light a day.
Proper soil and nutrient levels –
When it comes to soil I like a good mix of organics like Fox Farm ocean mix, you could use what you like just make sure it has the proper nutrient levels that marijuana plants thrive on. Plant food is measured in N-P-K (nitrogen (n), phosphorus (p), and potassium (k)). In the vegetative stage, plants thrive on nutrients that are higher in nitrogen. When looking for a good nutrient for veg., use a plant food that has a 20-10-10 npk or a 30-15-15 pk. For your flowering stage, you will want a completely different solution. In the flowering stage, plants thrive on higher phosphorus and potassium, and lower nitrogen. Use a plant food for flowering that has a 10-20-20 npk or 15-30-30 npk. Also, make sure to use a secondary nutrient throughout the growth of your plants. Secondary nutrients contain elements like calcium, sulfur, and magnesium with trace elements such as boron, copper, molybdenum, zinc, iron, and manganese. Your secondary nutrients are key for strong lush plants.
The water that you use should be clean, fresh, and have a ph balance between 5 and 6. With soil, you want your ph higher like 5.8-6. If growing marijuana hydroponically you will want a lower ph like 5.3. Your water should be room temp., and if stored in a reservoir there should be a pump moving the water around so the water does not become stagnate. Rainwater and distilled water would be optimal for plant growth.
Fresh air and room environment-
For optimal growth, the air temperature in the grow room should be between 70-75 degrees at all times and should have a steady humidity. In the vegetative room, you want the humidity to be around 60-75 % and in the flowering room, you want the humidity set around 50 %. The humidity level is lower in the flowering room to lower the chances of mold growing on your beautiful buds. Your plants will also need a constant flow of fresh air and an exhaust fan sucking all the old spent air out. To hide the pungent fragrances of cannabis attach a carbon filter to the end of your exhaust fan. For max growth and max potency you can introduce CO2 into the flowering room and veg room at around 1800 ppm (parts per million). Plants take in CO2 to grow and can take in up to 5 times more CO2 than what is naturally in the air.
If growing indoors your lights could make you or break you. During the vegetative stage, I have found that compact fluorescent lights work well for the seedlings, clones and mother plants. You also could use a 400-1000 watt metal halide lamp for optimal growth in the veg stage, but some of the drawbacks for the lamps are cost (they’re pretty pricy), heat, and higher electricity bill. If you’re a small-time grower just stick with the 4’ fluorescents, they work well. Just make sure they’ve planted spectrum bulbs. For the flowering stage, you will defiantly want to upgrade to a hp lamp or a high-pressure sodium light. The hips lights are pricy but they really do make the difference in the quantity and quality of the herb. For beginners or small opts I recommend a 600-watt has light. During the vegetative stage the light cycle should be set at 18-20 hrs of light and 4-6 hrs of complete darkness, this simulates the long days of summer keeping the plants in veg. when in the flowering stage you will set you has light to 12 hrs of light and 12 hrs of complete darkness, simulating the short days of autumn promoting the plant to flower. Make sure your flowering room is completely sealed off from outside light!
If you put all of these steps into play and create a perfect environment, whether it be indoors or outdoors you will be growing medical-grade cannabis for your personal use with amazing results.
Remember when choosing your seeds you want to get a good strain from a seed bank. Choosing which seeds to use is very important to the potency and size of your plants. Don’t try to use some seeds you have laying around the house. Buy from a seed bank!
