General Information about Growing Marijuana

There is one surefire way of avoiding high prices and the grass DT’s: Grow your own weed! This is not as difficult as some “authorities” on the subject would make you believe. Marijuana is a weed, and a fairly vivacious one at that, and it will grow almost in spite of you.

General Marijuana Growing Information

Both the male and he female plant produce THC resin, although the male is not as strong as the female. In a good crop, the male will still be plenty smoke-able and should not be thrown away under any circumstances. Marijuana can reach a height of twenty feet (or would you rather wish on a star) and obtain a diameter of 4 1/2 inches. If normal, it has a sex ratio of about 1:1, but this can be altered in several ways. 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.

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.

Seeds

marijuana seedsTo get good grass, you should start with the right seeds. A nice starting point is to save the seeds form the best batch you have consumed. The seeds should be virile, that is, they should not be grey and shriveled up, but green, meaty, and healthy appearing. A nice test is to drop the seeds on a hot frying pan. If they “CRACK,” they are probably good for planting purposes. The seeds should be soaked in distilled water overnight before planting. BE SURE to plant in the ground with the pointy end UP. Plant about 1/2″ deep. Healthy seeds will sprout in about five days. SPROUTING The best all around 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. When ready to transplant, you must be sure and 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/transplanting 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.

Outdoors

growing marijuana outdoorsContrary to popular belief, grass grows well in many place on the North American continent. It will flourish even if the temperature does not raise above 75 degrees. The plants do need a minimum of eight hours of sunlight per day and should be planted in late April/early May, BUT DEFINITELY, after the last frost of the year. Growing an outdoor, or “au naturel”, crop has been the favored method over the years, because grass seems to grow better without as much attention when in its natural habitat.

Of course, an outdoors setting requires special precautions not encountered with an indoors crop; you must be able to avoid detection, both from law enforcement freaks and common freaks, both of whom will take your weed and probably use it. Of course, one will also arrest you. You must also have access to the area to prepare the soil and harvest the crop.

There are two schools of thought about starting the seeds. One says you should start the seedlings for about ten days in an indoor starter box (see the soil and a little bit (not too much, now) of good water soluble nitrogen fertilizer. The soil should now be watered several times and left to sit about one week. The plants should be planted at least three feet apart, getting too greedy and stacking them too close will result in stunted plants. The plants like some water during their growing season, BUT not too much. This is especially true around the roots, as too much water will rot the root system. Grass grows well in corn or hops, and these plants will help provide some camouflage. It does not grow well with rye, spinach, or pepperweed. It is probably a good idea to plant in many small, broken patches, as people tend to notice patterns.

Indoor Growing

growing marijuana indoorsIndoor growing has many advantages, besides the apparent fact that it is much harder to have your crop “found,” you can control the ambient conditions just exactly as you want them and get a guaranteed “good” plant. Plants grown indoors will not appear the same as their outdoor cousins. They will be scrawnier appearing with a weak stems and may even require you to tie them to a growing post to remain upright, BUT THEY WILL HAVE AS MUCH OR MORE RESIN! If growing in a room, you should put tar paper on the floors and then buy sterilized bags of soil form a nursery. You will need about one cubic foot of soil for each plant. The plants will need air, so the room must be ventilated. (however, the fresh air should contain NO TOBACCO smoke.)

At least eight hours of light a day must be provided. As you increase the light, the plants grow faster and show more females/less males. Sixteen hours of light per day seems to be the best combination, beyond this makes little or no appreciable difference in the plant quality. The walls of your growing room should be painted white or covered with aluminum foil to reflect the light. The lights themselves can be either bulbs of fluorescent. Figure about 75 watts per plant or one plant per two feet of florescent tube. The fluorescents are the best, but do not use “cool white” types. The light sources should be an average of twenty inches from the plant and NEVER closer than 14 inches.They may be mounted on a rack and moved every few days as the plants grow. The very best light sources are those made by Sylvania and others especially for growing plants (such as the “gro lux” types).

Harvesting and Drying

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 cluster of white hairs. 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. 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. To cure the plants, they must be dried. 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 each 130 degrees. The box/room must be ventilated to carry off the water-vapor-laden air and replace it with fresh. A good box can be constructed from an orange crate with fiberglass insulated walls, vents in the tops, and screen shelves to hold the leaves. There must be a baffle between the leaves and the heat source. A quick cure for smaller amounts is to: cut the plant at the soil level and wrap it in a cloth so as not to loose any leaves. Take out any seeds by hand and store. Place all the leaves on a cookie sheet or aluminum foil and put them in the middle sheld of the oven, which is set on “broil.” In a few seconds, the leaves will smoke and curl up, stir them around and give another ten seconds before you take them out.

To Increase THC, or the Good Stuff

There are several tricks to increase the number of females, or the THC content of plants: You can make the plants mature in 36 days if you are in a hurry, by cutting back on the light to about 12 hours, but the plants will not be as big. You should gradually shorten the light cycle until you reach fourteen hours. You can stop any watering as the plants begin to bake the resin rise to the flowers. This will increase the resin a bit. You can use a sunlamp on the plants as they begin to develop flower stalks. You can snip off the flower, right at the spot where it joins the plant, and a new flowough a lab of some sort and costs about $35 a gram.)

To use the colchicine, you should prepare your presoaking solution of distilled water with about 0.10 per cent colchicine. This will cause many of the seeds to die and not germinate, but the ones that do come up will be polyploid plants. This is the accepted difference between such strains as “gold” and normal grass, and yours will DEFINITELY be superweed. The problem here is that colchicine is a posion in larger quantities and may be poisonous in the first generation of plants. Bill Frake, author of CONNOISSEUR’S HANDBOOK OF MARIJUANA runs a very complete colchicine treatment down and warns against smoking the first generation plants (all succeeding generations will also be polyploid) because of this poisonous quality. However, the Medical Index shows colchicine being given in very small quantities to people for treatment if various ailments. Although these quantities are small, they would appear to be larger than any you could receive form smoking a seed-treated plant. It would be a good idea to buy a copy of CONNOISSEUR’S, if you are planning to attempt this, and read Mr. Drake’s complete instructions.

Another still-experimental process to increase the resin it to pinch off the leaf tips as soon as they appear from the time the plant is in the seedling stage on through its entire life-span. This produces a distorted, wrecked-looking plant which would be very difficult to recognize as marijuana. Of course, there is less substance to this plant, but such wrecked creatures have been known to produce so much resin that it crystallizes a strong hash all over the surface of the plant – might be wise to try it on a plant or two and see what happens.

  1. when should i used fertilizer or any supplement for my plant?

    • Hey Fernandez!
      Good question, and a very important one. Do not fertilize your plants for the first 30 days. Then slowly introduce small amounts to the water. Its incredible important not to over fertilize, so follow the directions which come with your chosen fertilizer.
      More Information can be found on the fertilizer tips page.

  2. my plants are 7 weeks old and i changed my lighting from 20 0n and 4 off to 16 0n and 8 off and my plants leaves have started to curl –i use peters special fertilizer and a bud enhancer -i added the xtra light to the beginning instead of the end of my cycle for 3 days before i caught my mistake and changed it -i dont think i have overwatered them but it looks like im gonna lose them the realmsmall leaves look ok but the big ones are dying -was it my screw up with the lights that three them into shock –im lost please for any advice-i also am using a mixture of things to make a growing compound i got off a website that seems to be working——— lost in charleston— help

  3. My buddy says my Female Sativa forced The purple Kush plants in diffrent contains mind you to become Males. I think this sounds insane or am I wrong

    • PermaFrost King Reply May 8, 2013 at 5:17 pm

      That’s not it. Did you start the kush from seed? Did the plant get over stressed? Get rid of the males right away. Find another grower and get cuttings from them. Cut from those plants to keep the strain going and you won’t have this problem anymore.

  4. Iam using (6) 48 inch, T8, 32 watt lights for my grow. Can i grow and Bud with these lights?
