How To Grow Marijuana Indoors: Beginners Guide

From a basic view growing indoors is easy. Just make sure you have a secure location, plant good seeds or clones, a proper climate – air, light, water, nutrient, drainage and growing medium. Once planted seeds will begin their life cycle and turn into seedlings and then put on vegetative growth. At the end of the vegetative growth stage they will show male or female pre-flowers. When the flowering stage is induced, your plants will ready to harvest in about two months.

What do I need?


Marijuana seeds (aka cannabis seeds) are easy to purchase online or by mail. Many seed companies advertise in magazines like High Times, Cannabis Culture, Weed World etc. You can also get them from websites like Attitude Seed Bank or Nirvana Shop. You may even find seeds in a good bud from time to time.


Clones are exact replications of a female marijuana plant that has been cut from a branch tip and rooted. They are desirable because they flower sooner than seeds and are guaranteed females. Harvesting clones can be accomplished in about three months. Unfortunately, clones are not available by mail delivery. They must be purchased from a grower. A Google search for “buy clones online” will give you a list of potential growers you can get in contact with.

Grow Space

Where can I grow marijuana?

It’s possible to find a grow space in almost any home or structure. The ideal space should be enclosed so you can control the environment where the plants will grow. Some of the more popular options are in the corner of a basement, attic, closet or extra bedroom. Enclose the space with wood, brick, plastic or a prefabricated grow tent or cabinet.

Temperature Control

It goes without saying that the temperature and humidity in the grow space must be controlled. Optimal temperature for growth is about 75F (24C). Ideal humidity for growth is 50-70 percent during pre-flowering stage and 50 percent during flowering stage. The environment will most likely need to be heated or cooled slightly to maintain the ideal temperature and humidity. In many cases a ventilation face is the perfect solution to keep the ideal temperature and humidity.

Air Circulation

Circulating air with an oscillating fan provides the benefit of mixing the hot air on top with the cool air below so temperatures are more even throughout the room. More importantly, it allows the leaves to come in contact with new CO2. CO2 is used by the plant during photosynthesis to produce sugar for food.

Air Ventilation

Marijuana uses the available CO2 in a room pretty quick. It’s recommended to have a ventilation fan that expels used CO2 and an intake vent that draws in fresh, cool, dry air rich in CO2.


Add light with fluorescent tubes, compact fluorescent lamps (CFLs), light-emitting diode (LED), metal halide lamps, or high pressure sodium (HPS) lamps. Each have their pros and cons. Fluorescent lights are best used for growing seedlings and clones. Affordable CFLs from about 65-125 watts are able to grow small crops from start to finish. More expensive and versatile LED lights are considered the grow light of the future by many growers and range in a variety of options. Metal halide and HPS lamps are high intensity discharge (HID) lamps are range from wattage and color spectrum.

Water and Drainage

Can I grow with tap water?

Normal tap water is usually okay to grow cannabis with. If you can drink it yourself, it’s usually okay for you plants. If your water is rich in sodium, other minerals or taste bad, you may need to treat it with reverse osmosis. Such actions are not typical. Make sure the container you’re growing in does not hold the water and will drain from the bottom when poured.

Growing Medium


“Hydroponics” refers to growing in a soil-less blend that serves as an anchor for the plant roots. It allows for more accurate nutrient (fertilizer) uptake by giving growers more control over how much the plant receives. Hydroponic grow systems give the roots more airspace and allows for faster nutrient uptake than traditional soil gardens. There are a number of different hydroponic systems ranging from simple and cheap to complex and expensive.


Growing in soil is easy and simple. Many professionals recommend purchasing quality soil that drains well. In the event that you cannot find good soil, mix our own from quality ingredients. Organic soil gardens tend to flaunt the best aroma and flavor.

How to NOT Get Caught Growing Marijuana

It’s a shame that we have to worry about security to grow a plant that has been around much longer than us. Prohibition started in the United States about 80 years ago, Land of the Free. Many people around the world face the same problem today, making it is necessary to secure your grow.

Securing your grow room has several steps. Begin by restricting access to your garden and securing the perimeter. Do this by making sure you can control everything and everyone who enters and exits near the grow area. Keep the area under lock and key to prevent access. Make sure your not showing telltale signs including:

  • Aroma
  • light leaks
  • Noise
  • Debris
  • growing supplies

Consider all external forces that could be tipped off as well:

  • Telephone conversations
  • Tracking you home from hydroponic stores
  • Other growers or dealers houses
  • Lifestyle
  • Computer data tracking
  • Thermal imaging devices

Choose your friends and lovers wisely. Majority of busts are due to a jealous and vindictive lover or friend. Often times pressured by police to turn you in.

Security Checklist

What NOT to do:

  • Tell your friends.
  • Show people.
  • Throw something in the garbage that would incriminate you. It is perfectly legal for cops to root around your trash to determine what goes on in your house.
  • Have seeds or growing equipment sent directly to where you are growing.
  • Visit another grower’s house.
  • Partake in wild parties or spend time with real criminals.
  • Frequently visit the grow store in your own vehicle.
  • Go directly back to the place you are growing when you leave the grow store.
  • Forget to use a proxy server to prevent government agencies and criminals from tracking you.
  • Use your own phone to contact seed companies or grow stores.
  • Pay with credit card for all transactions related to growing.
  • Forget to pay with bitcoin or cryptocurrency.
  • Not have a guard dog.
  • Keep stored or otherwise not own a highly rated fire extinguisher.
  • Load any grow equipment when visibility is high and do it all a once.
  • Put utilities in your own name.
  • Own the home your growing in.
  • Act suspicious.
  • Have guns in the grow house. Sentencing will be seriously enhanced if busted with a gun.

Thermal Image Technology

In many places around the world thermal image technology is a legal means for authorities to search for potential growers. Regardless, thermal image technology is rarely effective with growers with less than 2000 watts. Running your lights during the day is known to confuse the technology. Well installing your grow house and expelling any heat without leaving a heat trail are another ways of taking precaution.


  • Never steal electricity.
  • Keep the electric bill and usage at a reasonable amount and keep the air in your house clean.
  • Inspect electrical outlets and connections for heat damage and repair immediately.
  • Ground all electrical connections.


  • Prevent grow room air-conditioner water from draining outside; it smells like marijuana.
  • Discharge any odorous air through a roof vent or chimney.
  • Use a carbon filter and an ozone generator to eliminate aroma. You can also look into odor absorbing gels and negative ion generators.


  • Muffle all noise from fans, lights, pumps etc.
  • Use insulated ducting
  • Reduce vibrating fans with rubber or foam fittings
  • Place ballasts on a noise-reducing base


  • Trust nobody – friends, family, lovers, siblings, even your parents.
  • Keep a regular schedule and simple routine.
  • Have a reason for using extra electricity.
  • Make large purchases over time and do not flash large amounts of cash.
  • Keep a regular job and reasons for your routine.
  • Prevent people from visiting when possible and keep to yourself.
  • Be a good neighbor.
  • Maintain your property and keep it neat a clean.
  • Drive a street legal vehicle.
  • Pay your bills on time to keep debt collectors away from your house and feds out of you finances.

Know Your Rights and the Law

In the worse case scenario be sure to know your rights. Do not answer any questions and do not consent to a search. If you have an encounter with law enforcement be sure to not answer any questions. Tell them “I want to talk to an attorney. I will not answer you questions.” It’s also best to let your lawyer decide what is best for you to say.

What to know if you encounter the police

  1. Do not consent to a search of any personal property including your house, car, or body.
  2. Never speak of any garden to cops. Do not indicate or show evidence of medical use.
  3. Request a lawyer.
  4. Never believe ANYTHING law enforcement officials tell you, your friends, family or anyone. They are trained to elicit information at the expense of telling a lie.
  5. Do not sign any statements, provide any information, or heed to their threats.
  6. Answer question with questions.
  7. Be nice but assertive.
  8. Prevent any extra charges and do not physically resist arrest.

Legality of marijuana

Whether or not it’s legal depends on who you are and where you are located. Before planning a garden make sure you have a clear understanding of the local, state, and federal laws regarding marijuana cultivation. Understanding the laws can help you decide if gardening is a realistic possibility. It’s also a good idea to make a plan based on worse-case scenarios.

In states where medical marijuana patients are permitted to grow there are often strict laws on the number of plants or the amount of space they occupy. Cultivating marijuana in most states is considered a serious offense and can often cause more trouble than it’s worth so it’s important to be cautious. Consider the following before you embark on your journey of growing.

  • Am I willing and able to manage the responsibilities and risks?
  • Can I afford legal representation if needed?
  • If you live with other people, how do they feel about it?
  • Is my area really secure?

Majority of arrest related to growing marijuana are due to “accidents,” lovers’ revenge, nosy neighbors or jealous friends. Statistics also show individuals who snitch in hopes to get out of trouble.
