Growing cannabis indoors 101

Your homegrowing journey starts with the question: indoors or outdoors?

Note that “mature” plants are those in the flowering stage, when plants begin to produce buds; “immature” plants are those in the vegetative stage, before they produce buds. A “household” is defined as two or more people living at a single residence.

Below are all the topics covered in our growing guide. That is followed by a list of where it’s legal to homegrow in the US and a quick overview of the growing process.

Check out our Guide to marijuana legalization for more details on homegrowing in your state.

What does a marijuana plant need to survive and thrive?

Growing weed indoors is more expensive because you’ll need to spend money on equipment and utilities, but you can control every aspect of the grow environment and set up an indoor grow almost anywhere. Expect to grow some killer weed—indoor is known for its potency and quality.

Growing outdoors is the cheapest and easiest way to grow, because you can utilize the power of the sun and other natural resources, but you need the proper space to do it, and the space needs to be able to get ample sunlight throughout the growing season. Often, you can let plants grow large and get big yields with more space outdoors.

Growing weed is super easy—it’s called “weed” for a reason—so don’t worry if you haven’t grown anything before. Our clear, easy-to-digest guide will help growers of all kinds, especially first-time ones.

Quick overview of the basics of growing marijuana

Because the plant was illegal for so long, a lot of grow info has been passed down by word of mouth. There are many myths and traditions about growing weed, so it can be hard to sort good, sound advice from hearsay. Also, because it was illegal, there’s ample information on indoor growing and how to get the most out of a small space by maximizing harvests and training plants.

Whether indoors or outdoors, growing marijuana is fun and rewarding, but it can also be challenging and takes a certain amount of patience, time, and money. We’ll walk you through all the steps of growing, from preparation, to seed germination, plant growth, and harvesting, as well as best practices and how to troubleshoot common problems.

Terra cotta pots offer a unique set of benefits to growers in hot climates.

It’s a good idea to start small—the smaller the grow, the less expensive it is to set up. Newbie mistakes will be less costly if you only have a handful of plants. Additionally, most state laws only allow for growing six plants, but some allow up to 12.

Getting the right climate for your plants can be a delicate balance involving multiple pieces of equipment and also lots of electricity. This is part of what makes growing weed indoors more expensive than growing outdoors.

Fabric containers

These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.

But the benefits are great: LEDs last much longer, use far less electricity, create less heat, and the best designs generate a fuller spectrum of light, which can get bigger yields and better quality.

The first step in odor control is making sure temperature and humidity are under control in your grow space—high temperature and humidity will perpetuate odors.

Multiple harvests

Unless you’re growing in a large, open space with a lot of ventilation, you’ll need air-cooled reflector hoods to mount your lamps in, as HID bulbs produce a lot of heat. This requires ducting and exhaust fans, which will increase your initial cost but make controlling temperature in your grow room much easier.

Make sure all equipment is on, no breakers have flipped, and everything is running smoothly. Check lights, timers, fans, dehueys, ACs, and anything else that plugs into the wall or has a battery.

The final step involves harvesting your plants. Once you get used to the process, you’ll find it more enjoyable than tedious.

Like most living things, cannabis plants need their “rest time.” If light from a surrounding source is seeping in during dark hours, the (bud-producing) females could get confused and develop hermaphroditic characteristics.

You don’t need a particularly large growing/cultivating space. A typical grow room for a small-scale grower is a small tent, cabinet, or designated area in a spare room, even an unused corner of the house is sufficient! Here are a few helpful tips to get started.

A hydroponic system delivers all necessary mineral salt nutrients to plants in water. If you want to choose hydroponic over traditional soil, there are several types which are straightforward and fairly easy to understand. These include Ebb and Flow, Flood and drain and DWC or Deep Water Culture.

Step 9: Set Time to Care For Your Plant (Every Single Day!)

Nikola Tesla invented the process of generating heat from magnetic induction in the 19th century. These types of lamps produce bright light with little heat compared to HID setups.

You must also operate within the boundaries of the law before getting started. Growing marijuana remains illegal in many U.S. states. Make sure home cultivation is allowed where you live before proceeding. Assuming you are legally able to continue, keep reading our detailed guide to growing cannabis indoors.

Light is essential for the growing process. Your plants receive direct light the majority of the time. Be direct here: eg. plants need 12 hours of continuous, uninterrupted darkness to flower and eventually produce buds.

3 – Keep Your Grow Space as “Light-Sealed” as Possible

Make sure you have consistent airflow across your entire plot. Depending on the size of your grow room, you can achieve this easily. Utilize several types of fans, including oscillating wall mount, stand fans, and box fans. Place them strategically to create good air flow throughout the space.

Lastly, some strains indeed require more calcium than others to produce robust, healthy nugs. Perform a little research on the particular strain you are growing. This process enables you to become more familiar with the kind of “food” it needs and prefers the most.
