Introduction to setting up grow box

growing marijuana step by step grow tent setup

Even though Marijuana is a strong plant, growing widely in different parts of the world, from Pakistani and Indian mountains to Africa or South America, naturally adjusting to extreme temperature and climatic conditions, there are great advantages to be drawn from growing cannabis indoors.

  • Privacy

Pot is still illegal in many places and growing it can send you to jail or cause issues resulting in heavy fines and legal troubles. You may also simply wish to hide the fact you are going from friends or relatives. In those cases, indoors is very useful as it gives you the ability to hide your plants from any unwanted guest

  • Get the best out of your plants

By confining your plants in indoor grow tents, you become able to create a controlled climate around them and act precisely on various factors such as light exposure and quality, temperature and humidity, meeting your plant every need, and forcing it to grow big fat buds.

In addition to that you can also upgrade natural conditions by using alternative systems like an aeroponic or hydroponic setup, allowing a healthy root growth that promotes bigger and healthier plant development, in order to maximize the yield.

In this guide we’ll help you understand what you need to know before you start to grow marijuana indoor, in soil or in a hydroponic system, and how you should consider installing the different components of your setup.

A marijuana grow tent is very handy for growing pot. It is basically a box made out of fabric you can install and fold very fast, containing all necessary holes and vents to allow cables and air ducts outside. It is covered on the inside with highly reflective materials, increasing light distribution through the canopy.


But before buying it, you should consider the following points:

  • Where do you want to set it up?

I recommend finding a hidden spot. Be careful with the windows and what people can see through it. When the box will be opened you will have a great deal of intense light coming out of it, and it doesn’t precisely look as the average one you have by your bed. Ventilation systems can be quite noisy so beware of your neighbors, especially in small flats and urban areas.

  • How much space is available there?

Start by measuring precisely your available space to avoid nasty surprises the day you unpack your new tent! It seems obvious but many people fail to do it and find themselves with useless equipment.

  • Do you have power plugs and access to water nearby?

You will need at least one power plug nearby, and by power plug I mean one that can distribute enough power to your setup. You will also need access to water to hydrate your plants, wash dirty pots, clean inside your tent and so on.

You can find complete grow tent kits on the market containing additional devices you may need, but be advised that the cheap ones may contain inadequate or low quality items, so always be sure to check the compatibility of the different elements sold in a kit before spending your money.

Otherwise you can browse through grow tent reviews, searching for the right fit, and purchase additional equipment separately, according with your project’s specifics. There are many models of grow boxes for sale, from the small grow tent to the professional super-sized equipment.


Whatever might be your project and the size of it, this is the minimum equipment you should have in your tent in order to promote a healthy and rapid growth:

  • A lamp, of course.
  • A ventilation setup, I mean a real intake/exhaust system.
  • A fan, to ensure air circulation around leaves and flower-tops.
  • Potentially a carbon filter to prevent the sweet smell of your plants from spreading through your house.

Marijuana grow lights

When it comes to lamps, there is a lot to know about.

Basically, the way you use them in an indoor grow session is by programming a grow light timer to have two different time frames:


  • Vegetation

During this first phase (18 hours of light, 6 hours of darkness) the plant grows and develop itself.

  • Flowering

During the second phase (12 hours of light, 12 hours of darkness) the plant stops growing and starts to flower.


There are plenty of lights on the market, and all of them have their pros and cons you should be aware of:

  • Fluorescent lights for plants.

Cheap, low heat production, low light penetration and short lifespan.

Low initial cost, high light penetration, heavy heat output, high energy cost.

  • LED lamps

Great spectrum, long lifespan, energy savings but high initial cost.

If you look for the best lights for growing weed, you might look for a long time as there is no real consensus among the growers about that. Everyone has its own favorite and the results you get depend greatly on the way you use it. Experienced growers are able to harvest more with a small lamp than new growers with a big one.


Budget considerations and tips:

Your choice might be based upon available money, as it is fairly common, and if so these tips will help you:

  • Very low budget:

If financial resources are limited, consider fluorescent tubes (t5 in particular) or HID lights, although  HID will cost you more on high energy bills and a more important air exhaustion is needed.

Avoid cheapest led grow lights at all costs as their quality is very low.

  • Low budget:

You may want to go for HID lamps as they represent a good compromise between efficiency and price.

  • Comfortable budget:

You can choose anything you like, ranging from HID to LED panels.


And don’t forget the plug-in timer !


Grow tent ventilation setup

It is vital for your plants to have a grow room ventilation setup. Without it, problems will rise as will the temperature inside your tent, wasting all the efforts you have made so far.

The minimum you must have for a small amount of plants or a small area is a grow room exhaust fan, as the intake can be passive, through your tent’s vents. In bigger grow rooms filled with humidity or when multiple lights are in use creating a lot of heat, an intake fan might be necessary to help cool or dry up the atmosphere.


Ventilation types:

  • Inline exhaustion fans

They are the basic fans with blades, and may be useful in small spaces with low heat output. They are not suited for bigger spaces, HID lamps, and cannot be used with a carbon filter as they are not powerful enough.

  • Industrial exhaustion devices

Those ones are industrial turbines, a lot more powerful than the previous ones, but also more expensive. They are the ones you need if you grow under HPS/MH lamps and if you use a carbon filter.

  • Cooltubes

The culture isn’t exactly an exhaustion fan. It’s a kind of big transparent tube in which the lamp is placed. The tube is then connected to the exhaustion fan via air ducts, and the fan sucks the air out of the box through the lamp, cooling it on the way.

  • Noise reduction methods

Have you ever plugged an exhaustion fan? Well, for the biggest of them, it sounds a bit like a plane landing, and to have a landing plane in your house isn’t the easiest way to relax, or to avoid nosy neighbors.

To enable people to live a quiet life, early growers have looked for ways to reduce the noise, primarily by rolling all kinds of blankets around the fans, and then tried more effective methods including duct mufflers, noise reduction boxes and insulated ducts, all of witch you can now find in your local grow-shop.


Carbon filters for grow rooms

You are happy. Your plants are budding, they look nice and healthy, but wait… What’s that smell?!

Yes, fresh weed tends to smell very strong, and unless you live in some isolated place, you need an odor filter.

The best way for controlling marijuana grow room sweet smells are carbon filters. They actually pull the odor out of the air, neutralizing any smells that pass through.


A carbon filter setup is handy when you need to neutralize the air coming out of your exhaust. A good carbon filter will make sure you never accidentally leak the smell of cannabis out through a window into your neighborhood.

They use activated carbon to absorb smells from any air that is pushed through it.


Find and install the right carbon filter

A carbon filter should be chosen accordingly to your grow space area and your exhaustion fan.

Make sure your fan is powerful enough to use the filter you plan on buying

The most common way to use them is to connect them as a part of your preexisting exhaust setup, preferably at the beginning, where the air is taken into the system, making sure everything that comes out of the box goes through it.
