There are many options for where to grow and your choice will mostly depend on your needs and what's practical. You'll want to consider stealth, available space, how much you want to grow.

Be creative and use or modify spaces you already have - as long as they meet the basic rules of a good grow space.

What makes a good grow space?

In the sections that follow we'll cover the pros and cons of the different grow space options, but there are a few rules that are common over all the possibilities:

Good ventilation: Without proper ventilation, the air in your grow space will become very humid and hot and lead to mold, disease, and stress. A good grow space is well ventilated to make it easy to exchange fresh air.
Heat control: Cannabis likes the same temperature ranges as you do; too hot or too cold and the plant shuts down. A good grow space keeps temperatures between 65F (18C) and 80F (27C) and never than 60F(15C) and never more than 90F (32C). Cannabis can take more extreme temperatures, but these ranges are good targets for indoor production.
Light Control: Traditional photoperiod cannabis strains need over 12 hours of uninterrupted darkness in a 24-hour cycle to flower. Even a quick sweep of light can cause the plant to stop flowering. A good grow space for photoperiod strains can be completely blacked out.
Vertical Space: Cannabis can get tall, from 1' all the way to 20' (6.6m) tall depending on the strain. You will need to select a strain that will fit into your space and use topping and training to make the most efficient use of your space and lights. Remember that lights hang down at least 1 foot (.3M) and you will need to keep at least the same amount between the lights and canopy. A good grow space is at least 2' (.6M) taller than the top of your plant after its done growing.

What options are there?

Outside - Cannabis is often grown outside and is an excellent option if available to you.
Space Bucket These are self-contained environment-in-a-bucket are perfect for single plant stealth grows.
Grow Box - They are a great option for small and stealthy grows for a single plant production. You can pick these up premade or make your own or repurpose an old piece of furniture.
Closet - A spare closet can make an ideal grow space because they offer good height and are good at keeping light contained. You will need a fan for ventilation in most closets.
Grow Tent - Grow tents range in size, from 2' x 2' (.6m x .6m) on up and are great options for all phases on cannabis life. Tents have great ventilation, reflective walls to make efficient use of lighting and they keep light contained to keep your grow stealthy.

Farmers often use multiple methods throughout the plant's lifecycle. For instance, you might veg in a space bucket, but move to a grow tent for flower, or veg in the sunlight and finish under lights.

Tents are efficient and stealthy grow spots with excellent light control.

Growing Marijuana Outside

Cannabis grows great outside in most places that people live, so it will probably work where you live too. You will need to select a strain that grows well in your region and environment.

Pros of growing outside: The light is free and on its own timer.

Cons of growing outside: Growing outside isn't very stealthy, and you won't have any light control.

Growing Marijuana in a Space Bucket

Space buckets are made by connecting a couple of five-gallon buckets to form a tube. Install 3 or 4 lights in the lid and cut holes in the side of the bucket for additional lights and fans. Add as many buckets as you want for extra height. In the end, you'll have a self-contained grow tube.

You probably have a lot of the stuff you need to build a space bucket already:

Pros of growing in a space bucket: Growing in a bucket is very stealthy and a reasonably efficient way to grow. Buckets also have excellent light control.

Cons of growing in a space bucket: Buckets are space constrained, and 3 or more 23 watt CFLs in a small area heats up very quickly. You will need to have plenty of ventilation and select a strain that does well in small spaces.

Growing Marijuana in a Grow Box

Grow boxes are self-contained cabinets meant to grow your plant from start to finish, like a space bucket. You can make your own from an old cabinet, lights, and fans.

You can also buy a turnkey solutions complete with lights and hydroponics kits. These make for perfect small stealth grows, but are expensive.

Pros of growing in a grow box: Grow boxes are stealthy, self-contained and have excellent light control. If you're space constrained or need to keep it all on the down-low, cabinets can be a great option.

Cons of growing in a grow box: Cabinets are space limited in all directions, so you'll need to proactively keep your plant the right size through topping and pruning. Buying a turn-key grow box is very expensive. Because of their size, grow boxes can overheat quickly without proper airflow.

Growing Marijuana in a Closet

Closets can make great grow spaces if available, just add lights and a small fan, and you're ready to go.

Pros of growing in a closet: You probably already have one, so there isn't an up-front cost. If your closet has a door, they are stealthy and have good light control.

Cons of growing in a closet: Closets don't always have proper ventilation and can be space constricting.

Growing Marijuana in a Grow Tent

Grow tents are specially made 'tents' with canvas on the outside and a mylar coating on the inside to reflect light back on the plants. Lights are hung from bars on the ceiling and fans can be placed at ventilation opening. Tents have a zipper door, and most vents can be velcroed, zipped or cinched shut for complete 'blackout' light control.

Tents come in a variety of sizes to suit your space. Make sure the tent has a metal frame and quality metal connectors. We've tested and can recommend these tents:

Pros of growing in a grow tent: Grow tents are efficient and have the best ventilation and light control of any option.

Cons of growing in a grow tent: Grow tents can take up a lot of space.

Keep it clean

No matter where you grow, keeping a clean grow space is a great preventative measure against pests. Keep old vegetative matter off the ground and don't leave standing water. Make sure to completely clean and disinfect between grows to prevent disease or pest holdover.

What do we recommend?

We recommend what works best for your setup and needs. Be creative, it's very common to start seedlings and veg outside or in a small cabinet and then move to the tent for the flowering stage. The most important things are that your space has good airflow and temperature and humidity control.
