People start growing and cultivating marijuana for a variety of different reasons. Perhaps you're underwhelmed with the quality of the weed you purchase or you just want to bring in some extra cash. Some people grow purely for medicinal reasons and others grow for social reasons. Without a prescription, you're likely going to be stuck with low-quality, overpriced weed---a problem that leads a lot of people to growing their own. Growing marijuana isn't difficult as long as you put enough time and effort into the hobby. Spending just a few hours every week can produce some fantastic results. If you're growing just for yourself, then you don't really require huge yields. A starter kit costs as little as $80 and can give you a nice start. Of course, growing marijuana always comes with some risks that vary depending on your location. If you're growing purely for private use, then marijuana cultivation doesn't need to be that pricey. Growing outdoors is easiest, because all the things needed to grow marijuana are essentially free. The sun rises every day, the plants get water from rain, and the soil is full of nutrients. In reality, to grow outdoors, all you have to do is buy some seeds. Of course, buying pots and growing your plants in fertilized, nutrient-rich soil could improve your results exponentially. You'll see an example list with prices a little further down. Growing indoors can also be inexpensive. CFL lights can provide you with an adequate yield without any spikes in your electric bill. A grow room with only a few plants doesn't require a fan and/or carbon filter to reduce the smell. All you really need are seeds, soil, pots, CFL lights, and a small fan, which should only cost around $80 (or less if you're good with your hands). Professional systems that produce higher yields generally only cost a few hundred dollars. Below are some shopping list examples: Indoor Basic (Amazon) $80 1 x 125watt cfl light $30 3 x 2 gallon container $3 1 x miracle grow soil $4.97 1 x fan $12 3 x high quality seeds $30 Indoor Pro (A fertile World) $350,- 1 x 600watt HPS bulb $49 1 x 600watt ballast $51 1 x 600watt reflector $34,95 1 x 500m3 exhaust fan $135,- 1 x 500m3 carbon filter $60,- 1 x fan controller $50,- 1 x time switch $6,95 10 x 2 gallon pots $10 3 x miracle grow soil $14,91 10 x high quality seeds $80 Outdoor (Amazon) $55,- 3 x miracle grow soil $14,91 3 x 15 gallon container $9 3 x high quality seeds $30 New marijuana growers frequently ask things like, "What kinds of yields can I anticipate?" or "How much good marijuana can I get from a single plant?" Of course, every situation is different and many variables determine how much usable marijuana you will end up with. Indoors Good lights are one of the most important factors when growing marijuana indoors. Veteran growers can achieve yields of around 1 gram (0.035 ounces) per watt of light. For example, a 400-watt HPS lamp can produce around 400 grams or 14 ounces of good marijuana. A grow room containing 1200 watts of light will translate to 1.2 kilograms or 42 ounces of good marijuana. The correct equipment, nutrient quantity, air quality, space between plants, and other important factors all contribute to the success of any indoor garden. For beginners, the yields will probably look like the following: An average of around 1.5 to 2.0 oz (3.5 oz for advanced growers) with 200-watt CFL lamps in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft. An average of around 3.0 to 5.0 oz (9.0 oz for advanced growers) with a 250-watt HPS lamp in a grow cabinet that measures 3.5 x 1.5 x 6.5 ft. An average of around 4.5 to 9.0 oz (14 oz for advanced growers) with a 400-watt HPS lamp in a grow room that measures 3.5 x 3.5 x 7 ft. An average of around 5.0 to 10 oz (21 for advanced growers) with a 600-watt HPS lamp in a grow room that measures 4 x 4 x 8 ft. An average of around 9.0 to 18 oz (36 for advanced growers) with a 1000-watt HPS lamp in a grow room that measures 5 x 5 x 8 ft. A great way to save money in the long run is to buy LED lights. They save money on electricity, and don't heat up a room like other grow lights which saves you money on air conditioning and fans.

With perfect conditions outdoors, you can yield up to around 18 ounces (500 grams) for each plant. It's important to have at least two meters of space between the plants. The plants also need enough water and nutrients without contracting any diseases or being attacked by pests. Containers (if you use them) should be the 50-liter (15-gallon) variety. Germinating the plants early in the season allows them to grow much larger. It may be in your best interest to germinate the seeds indoors so that you have total control over the temperature and humidity. For some, growing marijuana might just be about having your own home-grown weed. But, you really have to tend to your plants and make sure they're happy, so to speak. Everyone can grow cannabis. If you can't grow indoors, then maybe try your garden or a terrace on the rooftop. Forests, parks, cornfields, or a friend's garden are also applicable locations.
