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.
You might be surprised which states don’t allow homegrowing—only five medical states and one medical territory allow homegrowing at all, and some adult-use states require a medical card.
Your homegrowing journey starts with the question: indoors or outdoors?
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.
Indoor vs. outdoor marijuana growing
At the end of the day, you want to grow a strain you like. A single plant can yield between a half-pound and a full pound of dried buds, depending on how big your plants get, so you’ll have a lot of it come harvest time.
These are all great resources but not all growers want to put in that amount of time and effort to get a ton of weed—some growers just want to have fun, grow a little weed, and smoke something they grew themselves.
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.
Quick overview of the basics of growing marijuana
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.
Before you get started growing, you’ll need to see if you even can grow in your state. Below is a list of states in which it is legal to grow your own marijuana at home, both states with medical and adult-use legal status. If your state does not appear on this list, it is not legal to homegrow in your state .
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.
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.
The growth stages of marijuana can be broken down into four primary stages from seed to harvest:
Soil is the most traditional medium for growing marijuana indoors, as well as the most forgiving, making it a good choice for first-time growers. Any high-quality potting soil will work, as long as it doesn’t contain artificial extended release fertilizer—like Miracle Gro—which is unsuitable for growing good cannabis.
Check for pests, mold, or nutrient deficiencies
If your space is too humid, you may need to invest in a dehumidifier—also known as “dehueys.” However, keep in mind that while dehueys will reduce humidity, they typically increase temperature—you may need more fans or an AC when adding a dehumidifier.
Light emitting diode (LED) technology has been around for a while, and they are getting more efficient all the time. The main drawback to LED grow lights is their cost: well-designed fixtures can cost 10 times what a comparable HID setup would.
Fans are a must in a grow space to move air around, so buy some of those before an AC unit. If you find that fans aren’t bringing down the temperature enough, then you may want to invest in an AC.
Odor absorbing gels may help
Your cannabis wants a safe, healthy place for root development. Without healthy roots, your cannabis will never thrive. Roots are in charge of water retention, nutrient absorption, anchoring the plant, and they also facilitate vegetative growth.
Cannabis, like all plants, prefers certain environmental conditions in order to thrive. Temperature, humidity, light intensity, and airflow are all factors that will need to be monitored and regulated in order to keep cannabis healthy through its different phases.
