Growing Marijuana Indoors: A Beginner’s Guide

Marijuana has many uses, including medical.

Laws are changing globally with the Unites States now following the lead of Holland and marijuana being openly sold in dispensaries.

How about if you live somewhere where this herb is still criminalized? What about if you want to grow your own without needing to deal with dodgy dealers?

Today, we’ll look at the basics with this beginner’s guide to growing marijuana.

Cannabis is a very strong and fast-growing plant. It literally grows like weed. You can grow it indoors or outside and it copes well even with adverse conditions. All of these factors mean that growing marijuana is easy even if you have no experience.

Where To Grow?

You can grow marijuana outdoors no problem but it’s not the solution for most people.

Growing weed indoors is far safer.

In addition to the stealth factor, you will not be dependent on weather conditions. In many countries, growing outdoors is just not viable.

The first thing you need to think about is where you’ll put your growing set-up.

Some options:

  • Small room
  • Closet
  • Cellar
  • Shed
  • Loft

You’ll want to make sure your grow-op is secure and not on open display. Discretion is key.

As well as an electricity supply, you’ll need a window or vent to expel used air from your grow room. Think too about ensuring that fresh air can get into the room. This is important.

So, with adequate ventilation and light, you’re pretty well set to grow some great medical marijuana.

All you need is some basic equipment. You can spend a great deal for a large scale commercial set-up but for most home growers, the investment is minimal when you think of the enormous rewards.

Imagine always having your own supply of marijuana without needing to leave home or pay for it.

Your Growing Equipment

Everything you need is readily available online so you can order discreetly and easily.

Hydroponics are widely used for cultivating fruit, vegetables and orchids.

You’ll need:

  • Grow Lights
  • Fan
  • Grow Tent
  • Fertilizer
  • Seeds
  • Pots
  • Germinators
  • Potting Mix

Take care of those supplies and you’re all set to grow whatever strain you prefer. Whether you’re after an uplifting sativa or a relaxing indica, get the seeds of your choice and enjoy after as little as 8 weeks with auto flowering seeds.

If you’re growing marijuana, you’ll need a lot of light.

You have 2 main choices:

These lights produce a lot of light and they are inexpensive to buy. They remain a fairly common growing solution.

On the flipside, you’ll burn plenty of electricity with HPS lights and they kick off a lot of heat you’ll need to deal with.

LED lights are pricier but they are also far more efficient.

You’ll fight no battle with heat and you could increase yields by up to one-third.

Use HPS by all means but LED lights are increasingly becoming the smart choice.

Get Some Air: Fan or Filter

You’ll need fresh air circulating for best results when growing marijuana indoors.

In poorly ventilated grow-ops, the likelihood of crops being menaced by pests like mites is increased. At best, you’ll be hit with a diminished harvest. In the worst scenario, your whole crop will be ruined.

Get yourself a decent industrial fan and you can keep it running without expecting it to break down.

4-inch fans are adequate if you’re not using a filter. With a filter, opt for a 6-inch instead.

Installing a fan speed controller can help cut back on noise and reduce power bills.

Marijuana has an extremely distinctive smell. A carbon filter placed in front of your fan is one great way to combat this odor with activated charcoal.

Grow Tent

With a grow tent, you can keep everything nicely contained.

Next week, we’ll take a more detailed look at grow tents in a separate article.

The smell and bright light will stay sealed nicely inside your grow tent.

The reflective lining of the tent will ensure that all the light is directed onto your plants.

You can choose from a wide range of sizes from a small 2×2 tent right on up to 10×10 monsters and beyond.

Grow tents are not expensive. If you plan to grow at home, it makes sense to consider a grow tent.


Fabric grow pots are highly effective.

This type of pot works better than plastic. The oxygen reaches the roots effectively while any excess water drains off easily.

2-gallon or 3-gallon pots are generally what you’ll be looking for.

Marijuana Seeds

With everything in place, it’s time to get some of the best seeds you can.

Everything depends on your choice of seed from taste and smell through to yield so take your time.

Think about what you want from your weed when you use it. Do you want the buzz that comes with a good sativa to charge up your day? Or do you prefer the couch-lock of a great indica at the end of a hard day’s work?

Think about how much marijuana you actually need and how quickly you want it.

If you are a beginner and want to make things less complicated, roll with some auto flowering seeds. With this type of seed, the plants skip the vegetative stage and go straight to bud. This means you could be enjoying a full and plentiful harvest just 2 months after sowing the seeds.

Wherever you choose to buy your seeds, choose a reputable seller. You can’t go far wrong with the legendary Sensi Seeds. Gorilla is another industry heavyweight. They have a superb selection of seeds and a very informative website.


With everything in place, sow those seeds and get growing!
