How to grow weed indoors

Growing marijuana indoors is the most common and popular way to cultivate marijuana. The main advantage of growing weed indoors is that you are 100% in control of what you are growing and this tends to result in a better quality end product. You are not at the whim of the seasons like outdoor growers, meaning you can plant and harvest marijuana throughout the whole year.

Indoor Growing
For the novice it may seem there is an intimidating amount of information to work through, but the basics are easy. As long as you’ve built up a little knowledge, you‘ll learn how to grow marijuana indoors in no time.

What do you need to consider when growing marijuana indoors?

Are you a commercial grower, are you growing for medical reasons, or are you growing weed indoors for your own personal stash? The answer to this question will have a great effect on the space you choose to grow in. What you need to grow 2 or 10 plants makes a huge difference to the space, equipment, and the amount of money you’ll need to get up and running. Just knowing the answer to this question will enable you to pick a good space to grow marijuana indoors and maximize the quality of the weed you’re growing.

There are plenty of options that you might want to consider when growing weed indoors; you can close off the corner of a basement or attic, put an unused bedroom to use, convert a closet or purchase a pre-fabricated grow tent or cabinet. No matter where you choose to put your grow room, it should be enclosed to give you more control over the environment your marijuana plants will be growing in. Our basic guide on setting up a grow room will help get your indoor marijuana grow started.

Choosing a strain

The cannabis familyIf you’re growing weed indoors and have a lot of space, there is no limit to what you can grow giving you a large selection of weed strains to choose from. Do you want the uplifting high of a sativa like Super Silver Haze or Jack Herer? Or do you prefer the dreamlike body stone of an indica like AK47 and OG Kush? If you are inexperienced and have limited growing space, try starting with auto-flowering strains as they are more forgiving and tend to grow smaller. Use our section on indoor growing strains to help you make the right decision.

If you are looking to purchase seeds, make sure you get the genetics you’re after by using a reputable site.

How to grow weed indoors – Key decisions

What medium to use – Soil vs Hydroponics
Soil vs hydroAs an indoor grower, choosing between growing in soil or with hydroponics is a difficult decision to make as both growing mediums have advantages and disadvantages. The main influences on your decision will be based around your grow room space and budget. It is easier and cheaper to get started with a simple soil grow. However, a hydroponic system will produce a larger yield. If you need help choosing your indoor marijuana growing medium, you can find out more here.

Lighting – CFLs vs LED vs HIDs.
Marijuana needs light to grow. For outdoor growers, this is supplied by the sun. However, the indoor grower needs to supply a healthy amount of light to get their plants to grow. There are three main types of light that are used for indoor marijuana growing; CFLs (Compact Fluorescent lights), LED, and HID (High Intensity Discharge) which are normally a mixture of Metal Hallide (MH) and High Pressure Sodium bulbs (HPS). This is where budget and space really are important. Use our guide as each type of lighting system has its own advantages and disadvantages which are laid out in the lighting section of the website.

Water and Drainage
Plants will not grow without water. When choosing a suitable place or room for growing weed indoors, considering a water source is a must. Your water and drainage will be affected by whether you choose to grow in soil or hydroponics and in both cases you will need a reliable supply of good quality water. Advice on what kind of water to use to get the most out of your grow can be found here.

Temperature Control
Mouldy LeavesTemperature and environment control is very important for the weed you’re growing marijuana indoors. Outside, the majority of marijuana strains grow in a heat similar to those found in Southern California, the Mediterranean or the tropics. You will need to try and recreate these conditions indoors. However, too hot or too cold, and you will destroy your marijuana crop. Measure the temperature of your grow room, using fans to help regulate its temperature and supply fresh air to the plants.

Air Circulation
Your cannabis plant uses a lot of CO2, so good air circulation using a vent and fan to create airflow is important for a healthy grow. Good odor control helps keep the smell of your grow room at an unnoticeable level. You can find more information on air circulation and odour control here.

Air ventilation


Finally, when choosing your grow space you may want to consider security. You certainly do not want to bring any unwanted attention to your indoor marijuana grows. Don’t worry though, security issues are less of a problem and you will sleep easier if you deal with the following issues before starting.

– Noise – Muffling your fans and pumps will reduce noise. You can use rubber or foam fittings alongside insulating ducting to reduce noise.
– Fragrance – Growing marijuana indoors will smell. Having good odour control is a way of guaranteeing your neighbours will not know about your grow.
– Electricity – A spike in how much electricity you are using could be enough to alert your electricity provider so be as efficient as you can.
– Do not talk about your grow to anyone. The fewer people who know the better. You do not have to worry about anyone stealing your plants or informing on you if you don’t tell anyone in the first place.

Knowing how to grow weed indoors is about research and preparation. Ask yourself the right questions and plan your grow properly and you’ll be successfully growing weed indoors in no time at all.
