• Marijuana can be grown indoors or outdoors in many climates around the world. The plants enjoy a lot of sun or artificial light. Marijuana grows best in temperatures between 68 and 78 degrees Fahrenheit during light hours and will tolerate a drop of 15 to 20 degrees during periods of dark or night. For best results, the plants should be kept at a relatively low humidity of 40 to 60%.1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Temperature and Humidity a1b2c3.com: How to Grow Marijuana

• If you're growing marijuana indoors, you'll need to either find a place that gets a lot of sunlight or invest in some growing lights to ensure that the plants get the appropriate amount of light. Recommended types of lighting include:

1. Fluorescent lights
2. Metal halide lights
3. High pressure sodium lamps1st Marijuana Grower's Page: Indoor Cultivation Guide: Lighting

• Depending on the stage of the plants, you will have to adjust the length of time you leave the lights on. To help ensure that your plants get the proper amount of light, consider buying a timer switch.

1. For the first two weeks, give your plants about 16 hours of light per day
2. After the initial two weeks, give them at least 18 hours of light per day, but you can leave the lights on all day, if power usage is not a major concern for you
3. After the plants have reached a height of about 12 inches, reduce the light hours to about 12 per daya1b2c3.com: How to Grow Marijuana

• Marijuana grown outdoors should be planted in a location that receives at least eight hours of sun each day. Areas that get early morning and afternoon sunlight are the best. You should also have enough room to plant the seeds or seedlings three to five inches apart. Marijuana should be planted outdoors in the spring, after the last frost.a1b2c3.com: How to Grow Marijuana HowToGrowMarijuana.com: How to Grow Marijuana Outdoors

• Regardless of whether you are planting marijuana indoors or outdoors, you should plant it in sterilized potting soil or organic potting mix to reduce the chance that your plants will be contaminated by disease or bugs.

1. If planting outdoors, mix some of the sterilized or organic soil with the natural soil before plantinga1b2c3.com: How to Grow Marijuana
2. If planting indoors, plant the seeds or seedlings directly into the purchased soil in individual containers
3. Ensure that your pots or containers have holes in the bottom through which excess water can drain, or the roots may rot1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Watering

• If you are growing plants indoors, you will need to transplant them at least once during the growth cycle, since the plant's health will fail if the roots are allowed to become too cramped. Therefore, you should have two containers for each plant.

1. The first container you plan to plant in should be no larger than six inches in diameter
2. The second container should have a capacity of approximately three gallons1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Containers

• Plant your seeds or seedlings in the smaller container, allow them to grow for about two to four weeks, and then transplant them into the larger containers. Outdoor plants may also fare better if they are started inside and than transferred outside after two to four weeks.

• The soil your plants are situated in should be kept moist, but not wet. If the soil gets too dry, the plants will not grow as well. Water your plants regularly to ensure that the soil remains moist. As long as you have taken steps to ensure proper drainage, there is little chance that the plants will get too much water.

If you are keeping your plants indoors, do not use water directly from the tap: Fill a container with tap water and allow the container to sit for a day. Doing so will allow the water to reach room temperature, the optimal temperature for watering, and will also allow some of the chemicals to evaporate.1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Watering

Depending on your local climate and how much it rains, your outdoor plants may get enough water naturally. As with indoor plants, the soil should be kept moist, so water as often and as much as necessary to keep the plants moist, but not sopping wet.

• Although fertilizing your marijuana is not always necessary, as long as you do so in moderation, it will not hurt, and may improve the health of your plants. Since marijuana does not like particularly acidic soil and most commercial fertilizers make soil more acidic, it is important that you don't over fertilize the plants. Look for an organic fertilizer that is formulated for vegetables that flourish in low-acid conditions. You don't need to fertilize the plants for about the first month of growth, after which, you should gradually increase the amount of fertilizer and fertilize about once a week.1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Fertilizer

• Pest control is an essential part of care and maintenance when it comes to growing marijuana. Indoor growing conditions are damp and moist, which in turn are ripe for infestations of pests like fruit flies. There are a few things you can do for indoor growth to keep plants healthy and bug infestations at bay.

1. Bio-best spray: A commercial spray used by gardeners to keep bugs away from fruit and vegetable plants.
2. Sticky tape plates: Bugs are attracted to these plates, and wind up stuck in the glue
3. Neem oil: Neem is a natural, essential oil that repels bugs. This is a great option for organically conscious growers
4. Plantprotector: A commercial spray that repels bugs when spritzed over leaves

• Outdoor pests may also damage marijuana plants, so you will want to precautions against them as well. Here are a few outdoor tricks:

1. Pesticides: spraying plants with pesticides will keep bugs and other critters at bay.
   • Pesticides are often powerful and dangerous. Read all of the literature on your pesticide of choice before using, and make sure you clean plants of pesticides before burning marijuana.
2. Soap mixtures1st Marijuana Grower's Page: Famous Erowid Indoor Growguide: Bugs
3. Planting garlic around plants

• Depending on what type of results you are looking for, you can use elaborate lighting and watering systems to grow marijuana, although it is not necessary to do so. As long as the plants get enough light, are planted in good quality soil and watered regularly, they will likely flourish. Regardless of where or how you grow marijuana, keep in mind that, in most cases, it is illegal to do so.
