How to Setup Your Cannabis Grow Room Design

You might be thinking of setting up a cannabis grow room if you:

• Want to grow your own cannabis

• Need a place to grow cannabis discreetly

• Want to save money on cannabis

Whichever the reason may be, learning how to design and set up a cannabis grow room is a great way to achieve your goals.

As a cannabis grower, you know that space is at a premium. And if you're like most people, you don't have the luxury of an extra room to devote to growing your plants. So how do you create a grow room that's both spacious and efficient? In this article, we will outline some tips and tricks for designing the perfect cannabis grow room, even if you're limited on space!

Install proper ventilation and air circulation

One of the most important aspects of any cannabis room design is proper ventilation and air circulation. Without these, your plants will not grow healthy and robust. Installing a ventilation system is essential to maintaining a healthy grow room; make sure to size it appropriately for the amount of space you are working with. Additionally, be sure to install a fan or fans in order to circulate the air in the room. This will help prevent mold and mildew from forming and will keep your plants healthy.

Carbon Filter

Investing in a carbon filter will help your home from smelling like a weed factory. These are inexpensive and worth the money. Make sure you get one that fits your fan vent size. The carbon filter attaches to your outlet fan. It can be placed in or out of your grow room. Most people place the carbon filter at the inside top of the grow room/tent just below the ceiling.

Size the Ventilation System Appropriately

As we mentioned above, proper ventilation is essential for any cannabis room design. But what size ventilation system do you need? The answer depends on the size of your grow room. The larger the grow room, the larger your ductwork should be or multiple fans may be needed. It's also important to note that fans should be able to move all of the air in the room at least once per minute.

Where to position inlet and outlet fans in the grow room

You will want to place your inlet fan(s) near the bottom of the grow room in order to draw cool air into the space. The outlet fan(s) should be placed near the top of the room in order to expel hot air. By doing this, you will create a natural circulation of air that will help keep your grow room at a consistent temperature.

My personal favorite exhaust fans are from AC Infinity. Very high quality and they are the best you can get for home/hobby use.

Choose the right lighting for your plants

When it comes to lighting for your cannabis plants, there are a few things to consider. The most important factor is the type of light you are using. There are three main types of cannabis grow lights: HID, LED, and CFL.

HID (High-Intensity Discharge) grow lights are the most common type of grow light. They are efficient and powerful, and come in a variety of sizes. However, they also generate a lot of heat, so be sure to use proper ventilation when using them.

LED (Light-Emitting Diode) grow lights are becoming increasingly popular due to their energy efficiency and low heat emissions. They come in a variety of colors, which allow you to customize the light spectrum for your plants.

CFL (Compact Fluorescent Lamp) grow lights are the least expensive option, but they also produce the least amount of light. They are best suited for small-scale grows or as supplemental lighting.

When choosing a light source, be sure to consider the size of your grow room and how much heat the light will generate. Also, make sure to choose a light that's appropriate for the stage of growth your plants are in. Seedlings and clones will need less light than mature plants.

HID Grow Lights

The most common type of grow light is the HID (High-Intensity Discharge) light. HIDs are powerful and efficient, but they also generate a lot of heat. There are two main types of HID lights: metal halide (MH) and high-pressure sodium (HPS).

Metal halide lights are best for seedlings and vegetative growth. They produce a blue-ish light that is ideal for encouraging leafy growth. However, they should not be used during the flowering stage as they can inhibit bud development.

High-pressure sodium lights are best for the flowering stage. They produce a red-orange light that encourages bud development. However, they should not be used during vegetative growth.

LED Grow Lights

LED lights can be more expensive than other types of grow lights, but they will save you money in the long run due to their lower energy consumption.

CFL Grow Lights

CFL (Compact Fluorescent Lamp) grow lights are the least expensive option, but they also produce the least amount of light. They are best suited for small-scale grows or as supplemental lighting. CFLs come in a variety of sizes and wattages, so be sure to choose one that is appropriate for your space.

Control the climate in your grow room

Maintaining the right climate in your grow room is essential for healthy plants. The temperature and humidity levels should be kept consistent and within the optimal range for your plants. If the climate is too hot or too cold, or if the humidity is too high or too low, your plants will suffer.

There are a few ways to control the climate in your grow room:

1. Use a thermostat to regulate the temperature.

2. Use a humidistat to regulate the humidity.

3. Use a ventilation system to expel hot air and bring in cool air.

4. Use fans to circulate the air in the room.

Temperature

The ideal temperature for a marijuana grow room is between 70-80°F (21-27°C). If the temperature gets too high, your plants will stop growing and begin to suffer from heat stress. If the temperature gets too low, your plants will become more susceptible to pests and diseases.

An air conditioner and/or heater may be necessary to make sure your grow space stays in the perfect temperature zone. Indoor growing is perfect for all-year-round grows, but winters can get mighty cold and the plant could have a smaller yield.

Humidity

The ideal humidity for a marijuana grow room is between 40-60%. If the humidity is too high, your plants will become susceptible to mold and mildew. If the humidity is too low, your plants will suffer from drought stress.

It may be necessary for you to change the humidity in your grow room. This can be done by using either a humidifier or a dehumidifier. As the names suggest, a humidifier will increase the humidity and a dehumidifier will decrease it. In my area, the summers are too humid so I need to use a dehumidifier so my space stays comfortable.

Add soil, water, and nutrients to your plants

One of the most important aspects of growing cannabis is providing the plants with the right soil, water, and nutrients. The soil should be rich in nutrients and the water should be free of contaminants. The nutrients you provide your plants will depend on their stage of growth.

In the early stages of growth, your plants will need nitrogen, phosphorus, and potassium (known as N-P-K). These nutrients are essential for healthy plant growth. As your plants enter the flowering stage, they will need less nitrogen and more phosphorus and potassium. This change in nutrient needs is known as the bloom or flowering booster.

Hydroponics or soil

You can grow cannabis in either soil or hydroponics, but most growers prefer hydroponics because it is easier to control the nutrient levels and watering schedule. With soil, you have to be careful not to over-water or under-water your plants. Hydroponics systems are also less likely to harbor pests and diseases.

Choosing the Right Soil for Your Cannabis Plants

Soil is important to cannabis growth because it provides the plants with nutrients, water, and support. The type of soil you use will determine how well your plants grow.

There are two main types of cannabis soil: coco coir and potting mix. Coco coir is made from coconut husks and is a popular choice for cannabis growers. It is well-aerated and drains well, which prevents waterlogged roots. Coco coir is also rich in nutrients, making it ideal for cannabis plants.

Potting mix is a mixture of peat moss, perlite, and vermiculite. It is less expensive than coco coir and can be found at most hardware stores. Potting mix is not as well-aerated as coco coir, so it is important to add perlite or vermiculite to improve drainage.

No matter what type of soil you use, make sure it is sterile and free of contaminants.

Providing Your Plants with the Right Amount of Water

Cannabis plants need a lot of water, but they also need well-aerated soil. Over-watering can lead to waterlogged roots, which can cause your plants to suffocate and die. Under-watering will stress your plants and make them more susceptible to pests and diseases.

The best way to water your cannabis plants is to water them deeply and then let the soil dry out before watering again. This will encourage deep root growth and prevent waterlogged roots.

Watering A Hydroponic System

The best way to water cannabis plants in hydroponics is to let the roots grow down into a reservoir of water. The roots will absorb the water they need and the rest will drain back into the reservoir. You should only need to refill the reservoir every few days.

Cannabis needs an airstone to keep oxygen in the water.

Maintaining pH Levels in the Grow Room

Cannabis plants need a certain range of pH levels in order to absorb nutrients. The ideal pH level for cannabis plants is between 6.0 and 7.0. If the pH level is too low, the plants will not be able to absorb nutrients. If the pH level is too high, the plants will absorb too many nutrients and could become nutrient-burned.

You can test the pH level of your grow room using a pH meter. You can also buy pH testing kits at most hardware stores.

• Ideal pH for Hydro: 5.9

• Ideal pH for Soil: 6.5

Buy yourself a set of pH Up and Down solutions to make controlling your pH easy.

Adding Nutrients to Your Plants

As cannabis plants grow, they will need more and more nutrients. The best way to provide nutrients is through a nutrient solution. You can buy nutrient solutions at most hydroponic stores or online.

Most cannabis growers use a two-part nutrient solution. This means that there are two separate bottles of nutrients, one for the vegetative stage and one for the flowering stage. The vegetative stage nutrients are high in nitrogen, while the flowering stage nutrients are high in phosphorus.

You will also need to use a pH-balanced nutrient solution. This means that the pH level of the solution is between 6.0 and 7.0. You can buy pH-balanced nutrient solutions or you can mix your own.

You can also use organic nutrients, such as compost tea or worm castings. These are less likely to cause nutrient burn and are better for the environment.
