How to Grow Marijuana Indoors

Grow guide for marijuana beginners.

What you need to consider before growing marijuana

Growing marijuana indoors is a pretty expensive way to grow.  At the same time, it is more secure, gives you more control and allows to grow a few crop s a year.  Think of it as growing out in the open, leaves you open.  Before you do anything you need to decide:

  • Will you grow to open a dispensary or to sell wholesale.
  • How much do you need to make to cover expenses and make a profit.
  • How you are going to grow, hydroponically or in soil.
  • You need to determine how many plants you want to do each cycle.
  • Will you grow from seed or clones and what are the costs related to whichever you decide.
  • How big of a building you will need.
  • What type of lights system, HDI (High Intensity Discharge) or LED.
  • Pots or buckets.
  • Soil or hydroponic grow material.
  • Nutrients.
  • Irrigation system.
  • Air Conditioning.
  • Heaters.
  • Fans.
  • Ventilation.
  • Air Scrubbers, because there is an odor that you do not want spreading through your neighborhood
  • Humidifiers
  • Dehumidifiers
  • Pest Control

And so much more…

Electricity Costs

One thing that people sometime forget is the cost of electricity, which is your biggest expense.  Your monthly bill will increase by $1,000.00 to $2,000.00 a month.  It all depends on the lights that you use and the temperatures outside.  HID’s use a lot of energy and give off a lot of heat, which makes A/C unit(s) a requirement.  In the cold months, heaters will be required when the lights are off.  The expense electrical expenses just accumulate and accumulate.  When you receive your monthly bill, you better be able to pay for it, because a payment plan will not work if the next month you will have the same high bill.  I have seen people who made the mistake of not considering the electrical costs and had their electricity turned off.  I hate to see that happen.


You really should not even consider growing indoors unless you have Solar.  Using renewable energy, even if you are still tied into the grid, will keep your electrical costs down.  Whatever your solar intake does not cover, you will be billed once a year and you can break those payment down monthly over the next, while that years electricity grows for the next year.  Plus, you will have to pay the solar company monthly, usually a low fixed amount for using their solar equipment and system.

Power Outages

If you experience power outages often and for extended periods of time, then you will want to invest in a really good generator.  Even if you are on solar and attached to the grid, your power will still go out it the grid goes down.  With solar you can purchase a backup battery system, which can be quite costly, but if you can afford it, well worth it.  Propane generators are longer lasting, than the gas counterpart and can be set up to automatically kick in in the event of a power outage.  This feature is not necessarily a good feature for grow marijuana, if the power goes out you want to assess what stage your plants are in and the best course of action.  Having manual control of your generator would be best.

LED vs HID Grow Light Systems


LED grow light systems have come al long way the past couple of years and are improving constantly.  LED light system use less energy while putting out higher wattage.  The wattage you want for growing and producing big yield is 1000 watt lights.  LED’s will do 1000 watts and the cost will be equivalent  to 800 to 600 watts of energy.  The initial cost of LED’s runs about $1,200 to $1,500 per light, but they last longer, are easy to switch from the veg light spectrum to the bud spectrum (it literally is just a switch) and do not produce the heat that HID’s make.  So you will also be able to conserve energy by turning off the AC’s unit or at least turn them down.  If you want hight profits in the long game, then use LED’s.



HID light are the traditional grow light that is used for veg and bud.  You will need to purchase different light bulbs for the different stages and you have to manually switch the bulbs outs.  Bulbs should be changed at least every 2 group cycles.  HID give off a lot of heat, use a lot of energy and are quite delicate.  Bulbs and ballasts can be easily blown.  If you want to use these lights, which are significantly cheaper than the LED, in the long game you will actually be paying way much more.

My true suggestion is to purchase top of the line LED lights.  Kind and anything by California Light Works.  You will save so much money and hassle, so it is worth the initial expense and you still get high yields of big, dense quality bud.


Security is so important.  This industry is still a “need to know” business.  You only want to tell a very select few that you trust absolutely about what you are doing.  If you trust the wrong people, they may steal your crop right before harvest.  It happens way more than you think.  Security cameras are a must have.  Spend money on a top of the line security camera set up.  You want to be able to see what is going on at night and when you are not home.  So make sure that you can access the cameras on your phone or a tablet.  Alarm system is also a necessity, but not necessarily a system tied to a monitoring station.  Just something that you can hear a sound if the doors are opened.

Hydroponic Growing Systems

Growing hydroponically is a great way to grow marijuana.  You use liquid nutrients, which you can get organics, to supplement the water.  You will also need Rockwool grow block to place the plants in and media to fill the buckets, clay works great.  You may think that you use more water with hydroponic systems, but you really don’t use that much at all.  You can recycle the water unlike with soil pots, so you actually conserve water.  You do not necessarily need to buy an automated hydroponic system.  We grow hydroponically with white 5 gallon buckets but we hand feed each plant in the morning and evening.  It helps keep better quality control and pay close attention to each plant.  It helps monitor pests, keeping the plants trimmed and free of dead leaves.  Auto systems really are a waste of money.   As you learn to grow you will develop your own system that works best for you.

Orca Grow Film

Orca Grow Film is a paper that you line your walls with.  It is a special diffusing paper that increases lumens.  So if you have 1000 watt lights, you will get more lumens, which is an increased intensity of light.  We have used it since we started growing and swear by this product.  To learn more click on picture link.  You really will be amazed at what this film can do.

Grow Tents

There are grow tent kits that would be a great way to start growing.  You buy the kits and you will receive most of the items that you need to begin growing.  There are choice of square foot size, LED or HID lighting, fans, air intakes, ventilation and more.  DO your research and find the one that fits your space and has what you need.  You will still need to purchase buckets, rockwool, media, AC, heaters, humidifiers and de humidifiers, but at least you get a good deal on an instant growing space with lights.  Try to purchase a couple so you can multiple crops going at once.  Coordinating your plant cycles will be key in making a regular income.

Strains of Weed to Grow

You have choice of growing from a seed or purchasing clones.  We have always purchased top quality clones, it is more convenient and gives you about a months head start on your crop.  Do your research and only buy quality clone from a clone bank that has a money back guarantee.  If you kill the plant by doing something stupid, you are out of luck, but if you do everything right and plant just doesn’t take, them something may have happened during the cloning process and that is covered.  Study your strain and make sure that the strains you grow together are similar in growth time and environmental needs.

    I love this! Thank you for going into detail about all the extra costs and items you would need in order to grow marijuana indoors. I actually have a friend that was thinking of doing this so maybe I will send this to them so they can read up more info on it! Great read look forward to reading more!

      There is a lot to growing that needs to be considered before beginning. My husband and I have been through a lot with our growing business and I want to let people know that it is not easy by any means. My husband and I did a lot of research before we even decided that it was what we wanted to do and we still made many mistakes and wasted a lot of time and money. I want to share our experiences so that others do not have to go through the same or have any delusions about any aspect of the business.

      We will be adding more information on the in’s and out’s of growing hydroponically, which we found to be the best way to grow. I do hope that your friend does plenty of research before jumping into the growers industry. I have seen too many people lose so much after they failed due to being unprepared.

      Thank you for the comments and good luck to your friend.

    Great information right here,

    The consideration for electricity costs is something that I didn’t consider right off the bat.

    The paragraph on security is great, I live in an area that is a bit dodgy. If people knew that I was growing, they wouldn’t hesitate to break in and steal my plants provided that no one is home

    My country has recently approved medical marijuana, this article is great for those looking to be potential growers. Thanks for sharing this information!

      Congratulations on your countries recent addition to the medical marijuana family.

      I have known quite a few people that thought growing would be easy and then quickly find out that it is not and it can be expensive. It takes time, money and patience to grow. Then once they get their first electric bill their dream crumbles and they live in the dark. Electricity is the biggest expense that is why solar is the best route to go. If yo can get your solar set so you are off the grid, even better.

      Security is also something that people seem to forget about. They get so excited about what they are doing that they tell everyone they know, because it is legal now. Not good. This is mainly a cash business and each bud is money in of itself, and people that you thought were your friends can turn out to be a serious danger to your business.

      In the coming weeks we will be adding more information on how to grow hydroponically from clones through to harvest. So please do stay tunes.

      Thank you for the comment.

    I think you hit about every aspect that needs to be considered when growing marijuana. I like how you include all the costs and not just focus on the positives.

    Is this viable to follow when growing on a large scale? Is there anything that would need to be altered or changed?

      Hi Jaime,

      A person has to be focused, fluid and determined to grow marijuana. If you choose to grow on a large scale indoors, realize that the expense involved and have funds to cover the past, present and future costs. Many people think that it is easy money, but the reality is that so much can go wrong in an instant. Bug infestations, mold, nutrient deficiency and overdose, and combating temperature fluctuations. One lost crop will cost you not only in the cost of the plant and future crop, but the cost of water, nutrient and electricity.

      So, if you choose to grow at a mass scale, understand that it will consume your time, energy and money to assure that your yield is bountiful and profitable.

      Thank you for the comment.
