When growing weed indoors, you’ll likely have to add nutrients to your plants. You won’t need to add nutrients every time you water, but get on a schedule where you water every other time, or two on, one off.
You’ll likely yield about the same amount of weed in both cases, but more harvests mean you’ll have fresh weed to smoke more often and have more opportunities to grow different strains. But more harvests also means more work in cleaning up the space between harvests, trimming, etc.
While shopping for soil, you might be overwhelmed by the options available at your local garden store. The soil type is the basic structure of your soil. From there, look at nutrients, microorganisms, and other amendments that improve the soil. Your choices will be flooded with words like:
The two factors you need to control to dial in the environment are temperature and humidity.
Below is a list of things to consider and equipment you will need to purchase to get started growing marijuana indoors.
For small spaces or tents, clip-on fans can be attached to structures like walls, corners, or support beams. For larger grow rooms, use medium-sized oscillating fans or big floor models.

Humidity is the amount of water vapor in the air. Here are some ways to control it in your marijuana grow room:
You can connect a controller to fans, dehumidifiers, humidifiers, heaters, or air conditioners, and set thresholds whereby each device will power on and off based on your ideal environmental settings. Some units run autonomously, making changes based on set parameters, while others allow you to control each element via an app on a phone, tablet, or computer.
The first step is to cut off the big water leaves, otherwise known as the fan leaves. They have minimal THC in them and are generally removed. You’ll notice a visible difference between the long, green fan leaves and the smaller sugar leaves. The latter is covered in resinous glands (trichomes).
Harvesting hemp and cannabis is a lovely experience. It is one we recommend to any weed lover who has a passion for all aspects of the plant. You learn so much about cannabis and botany/biology in general. Most growers believe they learn something new with every harvest.
Induction lamps are an odd choice for indoor growers. However, some companies have recently adapted them for the cannabis industry. They can potentially represent decent value in terms of cost and efficiency.
Make sure that you have enough space to work in!
Step 10: Cut Your Cannabis Plants Down — Carefully!
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.
The 24-hour timer is just as important. When the marijuana plants are in vegetative growth, you need the light supply on for around 16-24 hours per day. Once they mature and reach the flowering stage, your plants need 12 hours light and 12 hours dark.
Most cannabis strains prefer an upper-temperature range between 75- and 85-degrees Fahrenheit. When the lights are off, keep room temperature between 55 and 75 degrees. Indica strains tend to prefer the cooler end of the range.
Final Thoughts on Growing Cannabis Indoors

The final step involves harvesting your plants. Once you get used to the process, you’ll find it more enjoyable than tedious.
There are several different types of grow lights that serve different purposes, each with their own sets of pros and cons.
When using soil as your primary medium, drain-to-waste is the only possibility. In soilless hydroponic systems, it is up to the growers’ preferences. Most hydroponic growers will opt to maintain a drain-to-waste system, because it affords them full control over the application of nutrients. Recirculating systems are typically reserved for the most advanced and efficient cultivators.
Fluorescent lights are affordable and use minimal wattage to produce a low-intensity light. They are available in strips or larger arrays of multiple bulbs, and are most commonly used during the germination and propagation of seeds and clones. They should not be used during the flowering phase.
Cleanliness in an indoor garden cannot be overstated. Clean your entire grow room before your first grow cycle and after every harvest. The walls, floors, trays, irrigation lines, reservoirs, lights, and fans should be cleaned using a three to five percent (3%-5%) hydrogen peroxide solution, an efficient sterilizing agent that leaves no dangerous or toxic residues behind. Be careful what you bring into your grow room. Pets, dirty clothes, and contaminated clones can introduce unwanted pests and diseases.
Grow tents also make it easier for home growers to maintain two separate environments: one for vegetative growth, and the other for flowering. This allows you to keep a perpetual harvest going by propagating and growing young plants in one tent and flowering another set of plants in the other tent. Maintaining a balanced rotation like this can result in maximized harvests year over year.
Cannabis feeding systems
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.
Air conditioning (AC) and humidification systems are used to control the temperature and relative humidity of an indoor grow room. The size of each unit is based on the amount of heat the lights and other equipment produce in relation to the size of the space. In an open grow room, intake and exhaust fans are used to constantly exchange the air within the room to maintain a consistent temperature. In sealed rooms, mini-split AC systems are used because they circulate the air in the room without bringing in fresh air.
