Building a Grow Room 101

With the continued expansion of legal marijuana across the United States, many entrepreneurs are looking into starting their own cannabis business. The key to success largely depends on its grow room — a controlled environment tailored for optimal plant growth. Efficient use of space, especially in urban environments or areas where real estate is at a premium, is vital.

Below we explore the basics of setting up a grow room, with a particular focus on vertical farming — a game-changer in the commercial cannabis industry.


The right lighting is essential for indoor cannabis cultivation because it drives photosynthesis, influencing growth stages and yields. Different light cycles and spectra impact the plant’s structure, bud production and potency. Consistent indoor lighting ensures optimal plant health and yield quality, unaffected by external environmental variations.

In grow rooms, choices range from HID and CFL lights to energy-efficient LEDs, which are preferred for their low heat and fit in vertical farming setups.

It’s crucial to thoroughly research and carefully consider the best lighting options for your grow room to ensure optimal plant growth and yield.

Irrigation System

Irrigation stands as one of the pivotal components of a successful grow room, playing a vital role in both plant growth and nutrient delivery. Despite its significance, it’s frequently undervalued in planning and budgetary phases.

Choosing the best irrigation system hinges on the specificities of your space, storage needs, and unique requirements. Therefore, diligent research into systems and partnering with a reputable company is essential for the best outcomes.


A well-designed ventilation system is vital for indoor grow rooms to ward off mold, fortify plant stems and regulate the CO2/oxygen balance. Exhaust fans are typically placed at the top to expel warm, stagnant air. Intake fans, located lower, draw in cooler, fresh air. Meanwhile, oscillating fans are employed to avert hotspots, distributing air uniformly without overwhelming the plants directly.

Space Needs and Vertical Farming

Space efficiency directly affects both the yield and cost in grow rooms. With limited space, it’s vital to use every available square foot effectively. Vertical farming, which encompasses the use of vertical shelving and stacking, is a great way to maximize space.

Movable shelving can significantly increase the number of plants a room can accommodate. These vertical systems are specially designed for the needs of growing plants. Efficient storage solutions like these can reduce losses and increase profits. At Systems & Space, our team works closely with growers to create a grow room tailored to each unique space.

Other Essentials

Setting up an effective grow room requires attention to various essentials. It’s crucial to maintain an ideal temperature and humidity level to prevent mold and pests. To address the potent smell of maturing cannabis, carbon filters are recommended for odor control. Moreover, routine monitoring of pH levels, temperature, humidity and nutrient mix is essential to provide an optimal environment for plant growth.
