For most first-time gardeners, we recommend buying a quality potting soil that will provide your plants with enough nutrients to get them through most of their growth cycle without having to add many amendments or liquid nutrients. This pre-fertilized soil—often referred to as “super-soil”—that can grow cannabis plants from start to finish without any added nutrients if used correctly.
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.
Standard plastic containers are a popular option for growers operating on a budget. These pots are inexpensive and provide the essentials for your plants.
Finding the right soil for cannabis
Although you’ll be controlling the climate inside the grow space, climate outside the grow space will affect your plants. If the environment outside your grow space is very warm or humid, you’ll have issues controlling your grow space. Choose a cool, dry area with ready access to fresh air from outside.
These are quickly becoming the standard. Roots in fabric pots grow to the outer edges and attempt to bypass the porous fabric wall but are cut back, allowing new growth to occur. This process, called “air pruning,” results in a denser root composition which promotes healthy growth and development.
The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flower.
Weed plants need different amounts of light during their vegetative and flowering stages. You don’t have to worry about this in an outdoor setting—the sun and the season dictate this—but when growing indoors, you will be controlling it.
Benefits of Hydro Over Soil
Differences Between Soil & Hydro
Hydro is a no-brainer for me. Whenever I go back to a hand-watered grow like coco coir, I am always surprised by how much extra time it takes to water plants and remove the runoff. The most intimidating part of hydro is just getting started – after that it’s actually really easy to take care of your plants. In my opinion, hydro is far easier and less time consuming than growing in soil or coco coir once you’re set up. If you are interested in hydro, go for it! If you follow this tutorial you will succeed!
Growing in coco coir can be considered a type of hydroponics since it naturally contains no nutrients and you must provide all the nutrients in the water. However, when you say “hydroponics” most people think of this:

When it comes to hydroponic cannabis…
e) Airstone and pump
Hydroponic systems are either active or passive, depending on the way they are designed. Active systems involve the movement of nutrient solution using electric pumps and the oxygenation of water using air stones. Passive systems are much more simple, and some rely on capillary action instead of electric pumps to deliver nutrient solution.
Materials Needed to Make a DIY Hydroponic System
Hydroponics is a method of cultivating plants, specifically cannabis in this case, in a solution of water and nutrients.
Perlite is a volcanic glass that expands when exposed to high temperatures. It’s often used in garden soils to provide aeration, which is exactly why it’s beneficial to use as a hydroponic growing medium for cannabis.
This system allows for periodic feeding. The time when the growing tray is empty allows growers to easily tend to plant roots and harvest plants.
