Growing medical cannabis and marijuana outdoors

Medical marijuana growing outdoorsGrowing medical cannabis outdoors, or au natural, has been the favoured method over the centuries. Growing medical cannabis outside simply means fresh air, natural sunlight, soil between your hands and 100% organic medical cannabis. medical cannabis seems to grow better without as much attention when in its natural habitat. The results will be a clean and natural product with no hydroponic nutrients added.

Of course, an outdoors setting requires special precautions not encountered with growing medical cannabis indoors. Growing medical marijuana outdoors you must be able to avoid detection, both from law enforcement freaks and common freaks, both of whom will take your medical cannabis without a seconds thought and maybe drag you off to jail with them.


There are two ways to germinate medical cannabis seeds. One says you should start the seedlings for about ten days in an indoor starter box, try using this guide to germinate the medical marijuana seeds. The other says plant them straight in the ground, pointy end up, about an inch under the surface in good soil. How you start your seeds off is a choice you will have to make.

To get good outdoor medical cannabis, you should start with the right medical marijuana seeds. A nice starting point is to save the seeds form the best batch you have consumed or do some research and buy proper outdoor medical marijuana seeds which is what we recommend you do. Yes they cost money but you will never doubt the seed strain and waste your time on super indoor variety.

The seeds should be virile, that is, they should not be grey and shrivelled up, but green, meaty, and healthy in appearance. A nice test is to drop a couple of test seeds on a hot frying pan. If they pop, they are probably good for planting purposes.


Medical Marijuana grows at this plantationMake sure the soil is fertile looking, brown with good drainage, not full of rocks, clay, lime etc. Note what else is growing nearby? Clear the area of medical cannabiss and general pests. You may want to dig out a hole for each plant. A hole about a foot deep and a foot in diameter works well. Line the base with 2 inches of gravel to enable good drainage and then fill the rest of the hole with good store bought potting mix as this kind of soil will be far better than most soils found on site. You could consider adding a small amount of slow release fertilizer but don’t go overboard as you will kill the plants with too many nutrients. Remember if you want it 100% organic maybe adding fertilizer is not for the best! Think about where the sun will rise and fall, don’t plant under big trees or in their shadows. Your babies need sunlight.

medical marijuana soil should compact when you squeeze it, but should also break apart with a small pressure and absorb water well. A nice test for either indoor or outdoor growing is to add a bunch of worms to the soil, if they live and hang around, it is good soil, but if they don’t, well, change it. Worms also help keep the soil loose enough for the plants to grow well.

Planting & water

The plants should be planted at least three feet apart, getting too greedy and stacking them too close will result in stunted plants due to lack of light. medical cannabis plants like water during their growing season, BUT not too much. This is especially true around the roots, as too much water will show you ‘root rot’ which means the plants are getting too much water and not enough oxygen.

Where to grow and protection – medical marijuana grows well outside when surrounded by corn or hops, and these plants will help provide some camouflage. It does not grow well with rye, spinach, or pepper-medical cannabis. It is probably a good idea to plant in many small, broken patches, as people tend to notice patterns.

Outdoor marijuana trees 

Unchecked marijuana can reach a height of twenty foot or more and grow tree trunks over 8 inches in diameter. Usually the male plant dies in the 12th week of growing, the female will live another 3 – 5 weeks to produce her younguns. Females can weigh twice as much as males when they are mature.


The best all round sprouting method is probably to make a sprouting box (as sold in nurseries) with a slated bottom or use paper cups with holes punched in the bottoms. The sprouting soil should be a mixture of humus, soil, and five sand with a bit of organic fertilizer and water mixed in about one week before planting.

To get some good extra information check out these marijuana pictures and refer to the germinating marijuana seeds page or the indoor germination process.

When ready to transplant, you must be sure to leave a ball of soil around the roots of each plant. This whole ball is dropped into a baseball-sized hold in the permanent soil.

If you are growing marijuana indoors, you should use a green safe light (purchased at nurseries) during the transplanting operation. If you are transplanting outdoors, you should time it about two hours before sunset to avoid damage to the plant. Always wear cotton gloves when handling the young plants.

After the plants are set in the hole, you should water them. It is also a good idea to use a commercial transplant chemical (also purchased at nurseries) to help then overcome the shock..

Marijuana grows like trees with enough light and waterMedical Marijuana vegetative growth

Your marijuana plants will start to grow very quickly given warmer days, access to plenty of sunlight and good soil that is not allowed to dry. Watering your plants can be a difficult problem given that sometimes you may live many miles from your babies, setting the plants up near a creek or other water source is very beneficial and solves the problem of carrying water into the site but will of course leave tracks back to your grow. You may also visit regularly bringing water in your backpack. Sometimes it can work well for a reservoir to drip feed the plants and the reservoir to be filled either automatically from a water source or by hand.

Marijuana sexing

The male plants will be taller and have about five green or yellow sepals, which will split open to fertilize the female plant with pollen. The female plant is shorter and has a small pistillate flower, which really doesn’t look like a flower at all but rather a small bunch of leaves in a cluster. More information on marijuana sexing and here also.

If you don’t want any seeds, just good dope, you should pick the males before they shed their pollen as the female will use some of her resin to make the seeds. Alternatively choose feminized marijuana seeds to begin with and you won’t get any male plants. Feminized seeds produce all female plants because they have been pre treated with a special chemical substance, again this can be against the ‘organic’ grow that some people look for.

After another three to five weeks, after the males are gone, the females will begin to wither and die (from loneliness?); this is the time to pick. In some nefarious Middle Eastern countries, farmers reportedly put their beehives next to fields of marijuana. The little devils collect the grass pollen for their honey, which is supposed to contain a fair dosage of THC.

The honey is then enjoyed by conventional methods or made into ambrosia. If you want seeds – let the males shed his pollen then pick him. Let the female go another month and pick her.

Harvesting Medical Marijuana

Harvesting, curing your outdoor medical cannabis plants. On large crops, this is accomplished by constructing a drying box or drying room. You must have a heat source (such as an electric heater) which will make the box/room at around 130 degrees Fahrenheit or dry it in a well ventilated room over warm airy days.

The box/room must be ventilated to carry off the water-vapor-laden air and replace it with fresh. We suggest drying in sheds, well ventilated rooms or outside under thick trees so it does not get direct sunlight. Drying will take many days and drying it faster will just ruin your organic outdoor buds. More outdoor drying ideas.

 Growing medical marijuana outdoor is a great way to help reduce your medicinal costs but as stated above does take some careful considerations.  Good Luck with all your medical marijuana growing!
