How to grow marijuana: A Prop 19 primer
If the law passes, Californians can grow their own marijuana in a space of 25 square feet. Here's how to get started.

Marijuana clones

GET STARTED: Clones, or clippings from an original "Mother" plant, will cost about $50 to $100. (Photo: spotreporting/Flickr)

If you live in California, now might be a good time to learn how to grow marijuana.
 
In a few days, voters in California will decide the fate of the “Pot Prop” — the state ballot initiative, Proposition 19.
 
Otherwise known as the Regulate, Control and Tax Cannabis Act of 2010, Prop 19, if passed, would allow, beginning Nov. 3, for people to possess up to one ounce (28 grams) of marijuana.
 
Prop 19’s potential passage also allows for individuals in California to grow their own, albeit in a space of up to only 25 square feet.
 
It’s a safe bet that growers will ignore the 25 square feet mandate, just as pot smokers country-wide have shunned the Federal Government’s Controlled Substance Policy, which has made marijuana consumption illegal for the last 70-plus years.
 
If you want to stay within the law and grow your own, 25 square feet — the size of typical apartment closet — should be enough to yield a small crop for personal consumption.
 
Beware though, marijuana consumption and distribution is still illegal under federal law.
 
California residents, however, will be in luck if Prop 19 is approved by a majority of voters.
 
If that heady vision comes to fruition and you want to take a stab at growing your own, consider hydroponic gardening, especially if you live in an area where access to an outdoor plot of land is hard to come by.
 
Before listing some of the basic ingredients required for home-grown bud, take note: the process is difficult for all but the most experienced and naturally green-thumbed growers.
 
First, you’ll need about $1,500-$2,000 for equipment costs. Expect to invest more for trial and error expenses.
 
Also, you’ll want to set aside $50 to $100 for your first clone. A clone is a clipping from an original “Mother” plant.
 
Some ganja green-thumb die-hards prefer to grow completely organically and start with a seed. The disadvantage of starting your own grow operation with seeds is it can take a full three months to cultivate from seed to weed.
 
If you’re lucky, one-pollinated female plant will yield only one or two seeds.
 
A clone, on the other hand, only takes about one month until bud clipping. A clone can be re-clipped over and over again, with no potency of THC (the main psychoactive ingredient in marijuana) lost in the process.
 
Caveat emptor when buying clones: some online operations have reputations for selling low-quality clones. The popular pot publication, High Times, is a good resource for buying clones.
 
Hydroponically grown pot also has a reputation of producing more aesthetically pleasing bud containing colored crystals.
 
You can read about which strains were winners at Amsterdam’s Super Bowl for marijuana growing, the Cannabis Cup.
 
Hydroponic seed growingHydroponic growing contains no soil. Instead, you’ll need a good light, tray, nutrients, pump, rockwool (think: tiny pebbles) and a timer.
 
To grow up to an ounce, expect to pay approximately $100 extra on your electric bill per light. Your hydroponic setup minus the light will cost $500.
 
There are a few different methods of growing hydroponic weed. There also are a handful of options for a light system.
 
One of the most expensive lighting systems is high-pressure sodium light, which closely mimics the sun’s rays and can cost upwards of $1,000.
 
Make sure your lighting system has a hood, which focuses light, and a ballast, which prevents overheating and provides ventilation.
 
You’ll also want a 3-foot-by-4-foot tray, which will yield about six to eight mature plants.
 
Your clones will be cocooned in a plug at bottom of the tray. The roots will be below the pebble (rockwool) line and only the roots will be exposed to water.
 
An intake and outtake, timer-based irrigation system is necessary to make sure the roots remain permeated but not totally soaked. If you’re on a strict budget, expose the clone to 12 hours of light. If you want your plant to bud earlier, expose the clone to 18 hours of light.
 
The mother plant should remain in a vegetative state. Some growing aficionados swear that mother plants can age like a fine wine. It’s not uncommon for some people to use the same mother plant for over a decade.
 
When you clip off a branch from the mother to grow more, make sure you use a razor blade to make a cut. Cut at approximately a 45-degree angle, 12 inches up from the root.
 
There are lots of different ways to grow your own. Some growers even use bat guano to organically compost their plant material. Some add molasses for a sweeter-tasting bud. Just like with any other weeds that can grow, marijuana growing is indeed a diverse, time and money-consuming endeavor.
 
California voters will decide on Nov. 2 if they can legally partake in this labor of love.

Plants will never bud under 18 hours of light. They must be put into 12 hour light periods to induce flowering. I have found my one true love and have been growing this variety for five years now. I always clone from this plant, grow vegetative under Metal Halide for 18 hours a day, and then put the plant into the flower room with High Pressure Sodium lights for 12 hour days. Time to bud under 12 hour days is 6 weeks to a month. I grow using a 10 gallon Sterilite tub, from Walmart, and net pots filled

with clay pellets. Four gallons of water with a few tablespoonfuls of FloraMicro, FloraGro, and FloraBloom in the tub feeds the roots. Cloning always produces true to form, and always produces females, as long as you clone from a female. DO NOT USE PESTICIDES FOR SPIDER MITES! Use spider mite predators. They really work, although they do take some time to gain control. After you establish a native population of predators you will never be troubled again by spider mites.

Edit time to bud is six weeks to two months.

ok first off this article is garbage heres why it doesnt take that much money to grow pot seriously and for the record dope isnt pot dope is heroin get your slang right now how much money you spend on equipment is gonna make the difference in the crop your yeilding i grew pot when i was 14 in my closet ( dont tell my mom lol ) but seriously with some seeds good soil aluminum foil and the right lighting and a minor source of knowledge i yielded a half pound from 4 plants trimming them helps alot

because it makes the plant bushier and allows more room for pods to grow

I am a 10 year experienced Organic Cannabis Grower who makes his own soil mixes, who makes his own powdered and liquid organic soil foods and who grows his own medical cannabis. Perhaps I can be of some help here? In a way the prices quoted are reasonable in that we end up spending way more that we should have. Perhaps things will change with more open competition. In all my time of buying equipment the only break I found was my first 1000 watt ballast and hood combo. Ballast, hood, safety glass

all at $300 but that was over 10 years ago. So wile it seems expensive it is actually to grow indoors so fight in your local areas to allow outdoor cultivation! However indoor growing can offer a more controlled grow and sometimes "High-Times" photo quality buds.

Well this article is inspiring but to get just a few seeds folks need to follow controlled pollination otherwise you will have several hundred!

most of this article is nonsense. you can't clip any buds in 1 month, it costs much less than 1500-2000 to set up, and i've gotten 100 seeds from a single bud site! And the $100 extra per month is complete crap, unless you're running 3 1000 watt halides. Again, this is total nonsense.

Not sure who wrote this, but it appears to be almost complete fabrication. Try Greenpassion.org if you want real info.

If anyone in California is paying $50-$100 per clone, immediately visit Southern California, where no clone at any reputable dispensary is over $20 and the best in the state OGs & other amazing Top Shelf clones are wonderfully plentiful and abundant.

Yes on 19, No on Cooley, No on Whitman.

Hydroponics is the most hardest way and yields the best buds, all this is true. Growing varies between different people and their methods. Growing outdoors does yield less THC content depending if its Indica or Sativa as well. It does take a green thumb to get the best of the danks. =)

Agree. This article is useless garbage. Anyone with a green thumb, some light, some good dirt, and some water can crank out amazing buds. Remember to leave the plants alone and do not over-fertilize. They'll do just fine. Trying too hard is what kills plants. You can do a full grow from home depot with no supplies from hydro-stores.

If you just throw any old seeds in the dirt and hope to get good bud, you'll be very disappointed. Those plants won't get hardly any THC in them. It's harder than it sounds. You way simplify things. Really. It's amazing how lazy people can be.

It needs to pass first.

Poll NO, Vote YES on Prop 19.

Poll NO when you could jeopardize your job or your standing in the community.

Vote YES when you are in the privacy of a polling booth.

I can't even begin to explain how many errors are in this article. Not one person should follow this advice unless you want to spend lot's of money and end up with nothing.
Do some research before posting this garbage!

If you're so smart, why don't you actually say what 'errors' are in the article.

It's one thing to get all emotional and call things 'garbage.' It's another to try to be helpful and say what specifically you believe is incorrect.

Do some research before commenting.

consider hydroponic gardening - no consider growing in organic soil to improve taste. Most hydroponic fertilizers are not organic. Most hydro gardens add sugars to make the buds way more and taste bad. Some ganja green-thumb die-hards prefer to grow completely organically and start with a seed - using a seed rather than a clone does not make you a organic grower. Clones are used because you know how the plant will grow and what it should produce. If you’re lucky, one-pollinated female plant will

yield only one or two seeds. - not true. A pollinated plant will yield over a 100 seeds if not more not just one or two. A clone, on the other hand, only takes about one month until bud clipping. - What are you talking about here. It will take 5 to 10 days for a clone to root. I then suggest growing your plant to about 2' or 3' which will take about 30 days then switch it to flowering which can take anywhere from 45 days to 75 days depending on the strain. It takes about 80 days to get a reasonably sized harvest from a clone. If you want a plant the yields you a quarter then start flowering in 30 days after you take the clone. Hydroponically grown pot also has a reputation of producing more aesthetically pleasing bud containing colored crystals. - wrong. You can change the color of your buds by using colder temperatures. Some strains have purple color genetics, hydroponic systems do not make colored crystals. One of the most expensive lighting systems is high-pressure sodium light, which closely mimics the sun’s rays and can cost upwards of $1,000. - you are getting ripped off. It should be about half that with the ballast, reflector and light bulb. look on line to find a better deal. If you’re on a strict budget, expose the clone to 12 hours of light. If you want your plant to bud earlier, expose the clone to 18 hours of light. - wrong again. If you were to expose your clone to 18 hours of light it will stay in a vegetative state. Your plant begins to flower on a 12 on 12 of cycle. If you want the plant to flower faster you switch to a 13 off 11 on. Just like with any other weeds that can grow, marijuana growing is indeed a diverse, time and money-consuming endeavor.- money-consuming endeavor only if your doing it wrong. It will take some start up funds but after the third harvest the money you have saved on buying weed will start to show.
