What size light do I need for my cannabis grow tent?

Cannabis may be nicknamed weed, but if you’ve ever attempted to grow, you know it needs careful tending to grow into a healthy, cannabinoid rich flower. From the soil composition to the air temperature and humidity, a good grower knows that nothing can be left to chance – least of all the lighting. 

Why good quality lighting is important in a grow tent

Growing cannabis plants inside gives you the maximum amount of control over every element of your grow. But since you’re inside, getting the right lights is of the utmost importance because cannabis is a light sensitive plant. 1

Cannabis is a photoperiod-dependent plant, which means its growing stages and yield are directly influenced by the amount of light it receives. Without the right amount of light, your plants will stagnate and fail to move into maturity. 

Not only will high-quality lights help each stage of your grow move more smoothly, they can actually increase the yield of your plants. The type of light and intensity of light can also affect your cannabinoid density, and the terpene profile. 2 3

But it takes more than just a good set of growing lights to have a successful harvest. You also need the right amount of lights and the proper intensity for your tent. If your setup is too big for the lights, each plant won’t get the energy it needs to grow strong and flower. If your lights are too powerful for your setup, they can damage your plants before they have a chance to get started, or as they flip to flower grow too close to the light. 

Factors of a good growing light

What makes a high-quality light? You’ll need to use several factors to find the best light for your grow set up, including: 

Efficiency. An energy efficient light uses less electricity to run, which costs less.Energy consumption. Part of determining a light’s efficiency is the energy consumption it takes to run. An efficient light will consume less energy than a traditional one, and  LED lights are more energy efficient than older grow lights like high-pressure sodium. Longevity. How many hours will the light last? You don’t want to invest in an expensive light, only for it to burn out after your first grow. Affordability. Every grower has a budget, and the best light for your grow tent won’t break the bank. Maximum lighting. How powerful is the light? Is it always running on maximum power, or is it dimmable for different grow stages?Cooling system. In the late stages of a grow, lights need to run for 12 hours at a time, which can easily lead to overheating. Does your light have a cooling system to keep it from getting too hot and burning out? Your grow space. Are you working in a grow tent or a converted bedroom? Large spaces need more lights than smaller spaces, and adding heat may be more desired in some grow areas than others. Brand. We all want things that work like they should. Brand loyalty is important to experienced growers to keep elements consistent.

One of the most important factors for getting the best grow lights is making sure they fit your grow space.
