*Illinois and Washington are adult-use states but require a medical card to homegrow.
Check out our Guide to marijuana legalization for more details on homegrowing in your state.
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.
What does a marijuana plant need to survive and thrive?
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.
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.
The best way to get quality buds and big yields is to grow strong, healthy plants. Here’s a quick rundown of the most important things you need to know about growing weed:
Quick overview of the basics of growing marijuana
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 .
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.
Coco Coir is the fibrous material found on and in coconut shells. As a byproduct of the coconut industry, it is favored by growers as a sustainable and renewable medium. Coco coir is an inert medium with a neutral pH that does not provide or maintain any nutrients. These qualities are great for growers who know how to appropriately adjust pH, allowing for quick pH and nutrient changes. There may be a learning curve, but if you’re numerically inclined, it’s not too hard to get a grip on the process. Coco coir can be used either by itself or added to soil or hydroton for improved drainage and growth capability.
Ebb and flow systems, also known as flood and drain systems, are a popular type of recirculating system that uses a pump to bring water and nutrients from a reservoir into a flood tray where the plants are positioned in their grow medium. The nutrient solution floods the tray and gets absorbed by the roots and medium before slowly draining back into the reservoir. This process repeats itself on a timer to ensure that plants are properly hydrated.
Setting up your grow: choosing a space
With lighting, AC, and other environmental controls in place, indoor cannabis plants will require large amounts of fertilizer or nutrients throughout their lifespans. Hydroponic systems lack the base nutrients that occur within soil; that leaves it up to you, the grower, to feed their plants with nutrient concentrations — the exact formula of which depends upon plant variety and phase of cultivation. With hydroponics, salt-based nutrients typically come in the form of a concentrated liquid or dry soluble powder that can be mixed with water.
