In this article, you can learn how to set up your own indoor grow room, including the best tips, tricks and techniques for healthy, happy plants – no matter where you live.
Here is a list of things you will need for a successful indoor grow room:
- Grow tent, closet, or room space
- Watering can, or hose
- Lights, or natural lighting
- Positive attitude in case things are more difficult than you expect
Why Grow Indoors?
Plants grow outside naturally, so why grow them indoors?
Indoor gardening is a great option for people who live in places where weather can harm or kill their plants, ranging from tropical places where rain and wind can uproot or drown them, to colder regions where seasonal freeze will destroy delicate plant leaves and root systems.
Setting up an indoor grow room allows you to more easily control the light, water, fertilizer and temperature so that you can grow any plants you want to, year-round.
Where Should I Grow?
If this is your first indoor grow room, you should start small and then scale it larger when you’ve had some practice. You can choose a small section of your house or apartment for smaller grow rooms. Once you have the concept, then expand or create more indoor gardens.
The beauty of learning the fundamentals is that once you’ve successfully done it, you can simply change the measurements to fit any new spaces you would like to develop.
The key to finding the best indoor spot to grow is water management. Inevitably, water will spill when making sure your plants get their needs met, so prepare accordingly.
Surfaces: concrete will provide the most stable surface to set your plants, planters, or grow boxes. It also wipes down easily if water is spilled, especially if there is any drainage system. Hardwood is not a great option because spilled water can become slippery for you, as well as growing bacteria and bugs that can harm you and your plants. Less stable surfaces are a poor choice and carpet is the worst, because it’s unstable and will hold onto spilled water.
Amenities: if the area is large enough, you may want running water. Otherwise a watering can should do. You will want to be near enough to electricity to be able to plug into grow lights, if your indoor plants don’t have access to plenty of sunlight.
Hazards: aside from unstable surfaces, children and pets are not always mindful when playing near your indoor plants. Make sure that watering cans, hoses, and any electrical wiring are out of harm’s way. Additionally, if plants are in planters or low to the ground, be aware that they could get knocked over or trampled on.
How Do I Set Up An Indoor Grow Room?
Once you have established where you are going to setup your growing area, make sure that there is plenty of space for you to access your plants when they need care. If you wish to grow your plants inside a dedicated closet or tent, skip down to those sections below.
A basement tends to be an ideal space to grow indoor plants because of the concrete floors and sometimes there is already drainage built in. The temperature is often more regulated, meaning it won’t get too hot and harm your plants. There’s usually less foot traffic in the basement, meaning pets or children are less likely to knock over your plants. However, basements can be poorly lit, which would require grow lights.
How Do I Set Up An Indoor Grow Room Inside A Closet?
A closet is an ideal safe space for plants to not get trampled, or knocked over.
However, plants may have a hard time breathing, and lighting is usually quite poor. This can be remedied using ventilation to and from the closet, as well as installing grow lights, which can be amplified by using mylar reflective film, or simply painting the surrounding walls white to reflect extra light.
Additionally, closets can retain a lot of moisture if water is spilled, causing mold damage to the closet and likely damage to the plants as well.
How Do I Set Up An Indoor Grow Room Inside A Grow Tent?
You can buy a dedicated tent to grow your indoor plants. Great for beginners, they are cost-effective in that you can place them anywhere in the house as their own self-contained unit, without needing to add many extra supplies to make them functional.
A good grow tent is usually pre-made and ready to install, which reduces the amount of time you will need to invest in creating a space. The walls are usually reflective to maximize the growing power of indoor lights. There is generally ventilation that’s easy to hook up so your plants can breathe. However, they’re usually a smaller, contained unit which means you might grow out of your tent if you want to increase the size of your indoor garden.
Your Indoor Grow Room – Step-By-Step
Once you’ve chosen a suitable location for your indoor grow room, go through this step-by-step guide to ensure the success of your plants.
Create a safe place for your plants in their new indoor home. You can do this by spacing out planters, or if you’re using a garden box style larger unit to hold multiple plants in the same container, space out the seeds.
Using store-bought potting soil, your plants should be ready for planting, or growing from seed. Make sure the soil is not too densely packed. If you’re using more natural soil from the great outdoors, it will need to be aerated so there’s enough space in the soil for plant roots to breathe. On the other hand, the soil should be firm enough to hold plant roots in place.
Regardless of your soil type, you will need the proper fertilizer. Check out our blog post for deeper insight into How and When To Fertilize Your Indoor Plants. We recommend liferocks special zeolite stones as the most eco-conscious, cost efficient and hands-off approach to indoor grow room plant fertilizer. One application to the soil lasts for up to 5 years and offers plants nutrients on demand, without harming their roots or leaves.
There are three main styles of grow lights:
Fluorescent LightsAn inexpensive option for beginners with few plants and small grow rooms. They produce less heat, which is safer for your plants, plus are more economical in that they use less power. However, they’re not powerful enough for the full life cycle of all plants and may not produce enough light for hungry adult plants.
High Intensity Discharge (HID) LightsThe best type of light for plants, but also the most expensive. In smaller grow rooms the heat from the bulbs may harm or kill your plants.
Light Emitting Diodes (LED)
The best overall choice for growing plants indoors, LEDs emit almost no heat, are directional (you can aim them straight at your plants), use much less power than other lights, and can last for 15-20 years. These are our hands-down choice for indoor growing.
Your plants will need plenty of water – but not too much. In a smaller space it may be easier to use a watering can with a longer, more accurate pour spout. Make sure you check the soil to be sure it’s draining properly.
If you really love your plants, you might want to use filtered water rather than tap water, to protect them from unwanted heavy metals and chlorine.
Plants need to take in carbon dioxide to create glucose, the energy that they use to create every part of their bodies. In a room with access to take in and expel air, this shouldn’t be an issue. But in a sealed space like a grow room closet, or grow room tent, you will need to add ventilation in order for your plants to breathe.
You will need to add tubes with both an intake fan that pumps air into the space, plus an exhaust fan that pumps air out of the space. This air transfer will also help control humidity and temperature.
You now have a complete guide to building your own indoor grow room for planting anything your heart desires. Your indoor space will vary, so make sure to tailor this advice to fit your needs and your situation. To recap, here’s what you will need:
- A safe space to grow your plants
- The proper flooring underneath to stabilize and repel spilled water
- Containers to hold the plants
- Soil for the containers, particularly well-ventilated soil so plants can breathe
- Fertilizer for the soil, especially liferocks for hassle-free gardening
- Lights, especially LED’s for maximum efficiency
- Fresh water, especially filtered and chemical-free
- Air flow to control temperature, humidity and allow the plants to breathe in CO2
