How to Grow Medical Marijuana

More and more countries are allowing the use and cultivation of marijuana for medicinal purposes. Many medical organizations support the use of medical marijuana as prescribed by a doctor, such as the American College of Physicians.[1] There are many places in the world where the use of medical marijuana is legal (e.g. Netherlands) and semi-legal (e.g. US – legal on the state level in some states, but illegal on a Federal level). If you have a prescription for medical marijuana but cannot find a source, and the growing of medical marijuana is legal in your country and locality, you may need to grow your own.


  1.  Get a script from a doctor

    Choose seeds according to the medical condition being addressed. The Indica strain is a relaxant, typically used to relieve the symptoms of multiple sclerosis, muscle spasms, tremors, mobility issues, and pain management. The Sativa strain is more of a stimulant, more appropriate for appetite stimulation, migraines, pain, nausea, and commonly used by HIV/AIDS and cancer patients and takes forever to mature. So really go for hybrids and get the best of both worlds.

    Find a place with enough light. If outdoors or in a greenhouse, at least 6 hours of sunlight are needed. If indoors make sure that the plants’ leaves are all strongly lit and receiving enough light. You will require a high pressure sodium bulb for the initial growth, and a different duration of light cycle: 18/6 for the vegetation and 12/12 for the flowering stages.

    Germinate the seeds. There are many methods of doing this. One way is to fill a cup up with warm water and drop the seeds in it. Keep them in a dark place for about 1 to 3 days. Whenever you see a white root popping out of the seed, it’s time to plant. Another way is to wet a paper towel and put the seeds in the paper towel and fold it and store it in a dark place for around 1 to 3 days. Or best way is just to use grodan cubes. You do not have to germinate the seeds, but if you do, it increases the chances of you having a plant sprout.

    Decide if the marijuana should be grown organically or using chemical fertilizers. The plant will be smoked, and therefore it may be healthier to use natural ingredients. Chemicals may give the bud an undesirable chemical taste, but may be cheaper and easier to dose accurately.

    Plant the seed in starter soil in a small pot. Seeds should usually be sprouted in starter soil or unfertilized soil, as fertilized soil may hurt the young plant. Seeds carry with them their own supply of nutrients for initial growth. Pure peat moss or very lightly fertilized peat moss can be used. Mix in some perlite so that the soil remains fluffy and is well aerated, as the roots require oxygen and can be suffocated by dense soil.

    • Water the prepared soil well, then make a hole about 1/2 in. into the soil and drop your seed in the hole with the root facing tip pointing up; the root looks for the heat of soil surface, gets close, then turns downward and pulls the opening leaves above the soil surface.
    • If the root is pointed down (as one would logically think), the root will go down looking for the surface, and then turn and go up, finds the surface and when time to turn down again has run out of energy.
  7. Cover the seed and keep the soil moist until the baby plant appears and begins to grow. Let the plant grow in this pot for about two weeks. Provide the plant with 18 to 24 hours of light per day. If using artificial light, use fluorescent lights. Do not use more powerful types of grow lights. Do not let the plant get too hot or too cold, 70 to 75F should be good. Provide adequate fresh, moving air with a small fan. The fan is important as the wind motion strengthens the fibers in the stalk allowing for better survivability to reach for the sun.

    Prepare the fertilized soil in a larger pot. Take a 5 gallon (18.9 L) plant pot and clean it thoroughly. An easy method involves first filling the bottom of the pot with peat moss to about an inch. You can find this at your local garden center (k-mart, Wal-Mart). This helps the sewage that the plant gives off, to drain very well. Then fill the pot to the top with some fine potting soil. Use an organic soil blend such as Vermit fire. Stay away from Miracle Grow products. More complex methods that may yield higher quality plants involves mixing together soil media and fertilizer in a separate container, then adding this to the five gallon pots. Organic soil mixtures may consist of 1 part perlite, 1 part worm castings, and 1 part peat. Also mix in small, measured amounts of fertilizer, such as bat guano. Use a high nitrogen fertilizer initially, as this supports vegetative growth. Be sure to read the fertilizer instructions and do not add too much fertilizer, as this will kill the plant.

    Transfer the young plant. Dig a hole in the large prepared pot and carefully remove the young plant from the small pot. This involves inverting the small plant in its pot while holding your hand over the top area of the soil, then letting the plant and soil fall into your hand. The soil will be held together by the plant’s root system. Gently place this in the hole and gently fill in the hole, being careful not to overly compact the soil. Water the soil, but do not over water.

    Watch it grow. The plant should get at least 3 hours of direct sunlight per day and should be watered whenever soil feels dry. The best growth occurs when the plant receives 16 to 20 hours of light per day. Never give 24 hrs of light. The plant never has time to rest before the next growth period. When this many hours of light are provided, the plant is said to be in vegetative growth, and it will not flower (so will not produce smoke-able bud) until about twelve or less hours of light are provided per day. Flowering will occur naturally when the plant is grown outside. However, if the plant was started late in the season, it will not have enough time to produce adequate or quality bud.

    Induce flowering if desired. But sex plants accordingly. Female plants will pop out a hair in the inter-node and the male will produce a ball. If you’re not sure wait a few days, it takes a few weeks for pollen to be produced. If growing with artificial light, induce flowering by limiting the hours of light received to about 12 hours per day. During the other 12 hours of the day, the plant must be in complete darkness for the entire time. A low nitrogen, high phosphorous fertilizer is used during the flowering stage.
  12. Grow Medical Marijuana Step 11.jpg
    Study the air temperatures and keep plants around 67°. Outdoors you do this by studying your seasons. Indoors this is done by reading the temperature and controlling the ventilation. Adding an hourly blast of Co2 from an electronic regulator & tank produces great results during the flowering stages. Even better if you run it during the transitions phase. (first 2 weeks of light being set at 12/12) 3rd week of 12/12 is the first week of flowering don’t get that wrong!
  13. Grow Medical Marijuana Step 12.jpg
    Sex the plant. You can tell if your plant is a male or female. A male doesn’t produce bud, a female does. You can tell if the plant is a male if there are pollen sacks (ball) forming around where the main stem connects to the branches. A female has white hairs (a hair) coming out at that spot. A magnifying glass can be used to look for the characteristic white hairs, if your half blind. Dispose of the male plants as they are not valuable sources of medically important constituents, but can be used to selectively pollinate a single flower inside a baggie over the flower. This provides you with future seeds that have adapted to your soil and conditions.
  14. Grow Medical Marijuana Step 13.jpg
    Harvest the plant. In about 8-16 weeks after transition, your plant should be ready to harvest when most of the hairs turn from white to red. NOTE; for dispensary quality cut when half of the trichomes are milky. For great smoke cut when 10-25 present are amber and the rest milky. For high CBD smoke cut when all trichomes are amber. Examine them with a 30-60X magnifying glass or loop. Cut the mature plant at the main stem above the soil, cut all sun leaves any leaves other then flower leaves, and hang it upside down on a clothes line for about 6-7 days at 65-70’f and 50-55% humidity. When the stem is no longer moist and can be broken simply trim off the buds from the stem and start the curing process using turkey bags to slowly finish drying. I removed the bad directions from here telling you to put in in paper bags as this will cause the chlorophyll to be stuck in the plant from drying too fast. Google Ed Rosenthal, he taught me and the rest of us potheads!
