How to Grow Cannabis Indoors: A Beginner’s Guide

How to Grow Cannabis Indoors

One of the most beautiful things about cannabis is that it’s a plant that can grow in your own backyard. California devotes hundreds of acres of farmland to the growth and harvest of that sweet Mary Jane. But even if you don’t have a 100-acre backyard, you can still enjoy home-grown cannabis. In fact, you don’t even need a backyard; you can grow cannabis indoors!

Growing cannabis indoors is not the cheapest or the easiest process, but once you have the basics down, you can enjoy a new hobby (and save some cash on buying and shipping cannabis products!)

Here is what you need to know in order to start growing cannabis indoors as a beginner.

Set Up Your Space

You can grow cannabis in a house, basement, or apartment, but you’ll need to set aside the proper amount of space to guarantee that your plants will flourish. Marijuana plants, on average, grow up to four feet tall and thrive best in a gallon pot. This is a considerable amount of space for one plant - and in California, you can have up to six plants in your home.

Section off a closet, corner, or space in the house where you can control the temperature, airflow, and lighting. Even if you have to buy extra equipment to manipulate these factors, you will at least have an enclosed space where no extra light or air can get in.

Get Your Equipment

Some growers like to control lighting, temperature, etc. by buying a grow room or a grow tent - these are enclosed spaces that may have lighting or temperature controls set to best nurture growing cannabis plants. These grow tents can be expensive and aren’t necessary to get the right heat and light for your plants.

Consider buying equipment that allows your space to be an optimal environment for growing:


At certain points in a plant’s lifecycle, they will require 12-24 hours of light to flourish. That isn’t always possible when your roommate’s trying to sleep or the days are shorter. Consider buying grow lights that can be monitored (or even scheduled) to give plants the light that they need. Grow lights may be CFLs, HIDs, or even LEDs. The right type of light will depend on your space, your budget, and even the stage of growth that your cannabis is in.

Heat Lamps

Cannabis likes moderate to high temperatures. During their lifecycle, you may need to keep your space heated between 65-85 degrees Fahrenheit. No one wants to hang out in a stuffy apartment that is 85 degrees, so space heaters or heat lamps may be the best choice for your space. Remember to create a space that is enclosed so that the heat from these heaters doesn’t escape into the next room!

Air Flow

Plants need water and light to grow - but they don’t need that moisture to stick around for too long. In rooms that rise up to 85 degrees, you need some sort of air circulation. This prevents root rot and other complications from moisture sitting for too long. In order to achieve optimal air flow, you may need to purchase a fan, exhaust system, or put your plants near a window or area where they have access to fresh air. If you are recruiting outdoor air to help with circulation, consider screens or other equipment to prevent bugs from enjoying your plants, too.
