How to Build a Grow Room for Business

Producing a good yield takes anywhere from a few weeks to a few months.

What if your setup could set you up for even faster production without sacrificing quality?

If you’re wondering how to build a grow room for your business, use this guide to help you plan out yours. A well-planned and executed grow room can last you generations. 

Set Up Ventilation And Hydration System

A ventilation system controls airflow into and out of your grow space. This is one of the most important features of an indoor grow room. It allows your plants to breathe and photosynthesize for food and energy.

Your primary goal with your ventilation system is to exchange humid air inside the grow room with fresh air from outside.

You should aim for the right level of humidity. Too much humidity and moisture can cause diseases such as bud rot. Too low humidity can lead to plant water loss and cell death.

Your grow room ventilation system should give your plants exactly the conditions and environment that they need.

These are some tools you may consider using to set up a ventilation system for your indoor grow room:

  • an intake and extract fan
  • carbon air filters
  • insulated flexible duct
  • air pressure monitor

For your grow room water system, be sure that the room is close enough to a water source so you can access water with ease. You can attach a hose with a spray nozzle to a water source, such as a sealed barrel drum with a water pump, to mist and water your plants.

Line The Walls

When you’re building a sealed grow room, you want to take advantage of all the light that you are using.

You can maximize your indoor grow lights by lining your walls with a reflective material. This will help to bounce the remaining light back onto your plants.

You might have thought about using aluminum foil or even a mirror to line your indoor grow room. They seem like reflective materials that should do the job. But, they’re terrible choices for your grow room.

Depending on the reflective material of the mirror, mirrors don’t reflect all the light of the light source. They absorb a tiny amount, and they’re quite fragile.

Aluminum foil is only half effective at reflecting light. This means that it will absorb a good amount of light that could have gone back to your plants.

Instead, some good choices for reflective material to line the walls of your indoor grow room are:

  • flat white interior paint
  • foylon
  • mylar reflective sheets
  • panda film or white poly plastic

If you’re using tape to hold up any of these reflective materials, keep in mind that your grow room will be humid. That will loosen the tape and undo your lining.

Choose Your Lighting

Building an indoor grow room for your plants means your artificial light source is essential. You want the right amount of light at the right distance in order to replicate the plant’s perfect environment outdoors.

The three most common lights for an indoor grow room are:

  • high-intensity discharge or HID
  • compact fluorescent lights or CFL
  • light-emitting diode or LED

Many growers use HID lights because they produce great yields at fast rates. They do, however, get quite hot and consume a lot of energy. This means a high energy bill.

CFL lights are energy-saving and low cost, which makes them great for beginners. However, their low light output limits the number of plants you can grow.

LED lights can stay cool while on and are energy efficient, which reflects low running costs during operation. However, they are more pricey at the start. If you find cheap LED lights, they likely won’t perform well.

Whether you’re building a small grow room or a large commercial grow room, lighting is key to producing good yields.

Make sure that you set up your lighting correctly from the start to avoid burning the place down or having to repair faulty systems down the line.

Consult with a licensed electrician for the green light for your grow room and learn more about how much they charge for the job. You can make the right decision after you get a quote.

Control Climate Settings

Aside from humidity, temperature and CO2 levels are two factors that contribute to an ideal environment for your indoor grow room.

The vegetative and flowering stages of plant growth do best in the high 70s (or 25°C). Before you harvest, you can drop the temperature to the low 70s (or 23°C) for the flushing stages.

However, the temperature will vary depending on the strain and your specific grow room conditions.

When temperatures get too hot, you must modulate levels of CO2 and water to keep your plants happy. Invest in a thermometer to keep an eye on your grow room temperature.

You can also intentionally increase levels of CO2 to foster more rapid growth in plants.

CO2 generators or compressed CO2 tanks introduce more CO2 into your grow environment, but not at a controlled rate. Be sure you know what you’re doing before making the jump.

Introduce The Plants

The last step in building a grow room is, of course, introducing your plants to their new home.

Set up your vertical grow racks to help you save space while growing. Elevate your racks off the ground to help air flow circulate through the room and around the plants.

Once you’ve set up all ventilation, hydration, and lighting systems, and you’ve ensured that your room is smell-proof, you can begin to move the plants in.

If you set up correctly, you can build a grow room that can last you generations.

Because your grow room is indoors, you must control and adjust all the variable factors to produce the most perfect environment for your plants.

When you keep your plants happy, your business thrives. So, plan out your room today and execute!
