As a cannabis cultivator, one of the most important aspects of growing great weed is creating the perfect environment for your plants.

They are designed to keep things simple and make it possible to produce quality buds when growing weed with less equipment. In this article, we will provide a complete guide to being successful when cultivating in the weed growing tent!  By introducing you to all the temperature, light, and humidity information you’ll need to know to grow healthy plants and of course, add in some special tips for growing cannabis along the way! 

What is a Grow Tent? 

First things first, What is a cannabis grow tent? Grow tents for weed are temporary structures designed for cannabis cultivation. It offers a purpose-built place to hang lights and fans without permanently modifying a residential space. A weed grow tent is made of a reflective material on the inside to maximize light reflection and a black or dark exterior to prevent light leaks. They are also designed to be easily put up and taken apart, making them a great option for growers who need to move their setup frequently. With doors on either end making plants easily accessible, pockets that make adding outlets and ventilation equipment a breeze, and different size tents for all growers; tents for weed make it so much easier to grow marijuana indoors.

Setting Up Your Marijuana Grow Tent

When setting up your cannabis grow tent it’s important to follow these step-by-step instructions carefully to ensure a happy harvest. 

  1. Select a suitable location for your grow tent, preferably a cool, dry, and dark place.
  2. Assemble the grow tent according to the given instructions by starting with the framework. 
  3. Install the ventilation system, including the fan, ducting, and carbon filter.
  4. Install the grow lights and hang them at the appropriate distance from the plants. Use rope and carabiners to adjust lights accordingly throughout their growth cycle.
  5. Set up an automatic timer to control the light cycle. 
  6. Now it’s time to install a thermometer and a hygrometer to monitor the temperature and humidity levels easily and often. 
  7. Add your cannabis plants while making sure they have adequate space to grow.

 Remember: Space is important so plants can grow outward, more plants don’t necessarily mean a higher yield at harvest time. Too many plants will affect the temperature and humidity levels of your tent, so you need to think ahead. What size pots are appropriate for your grow space? How many plants can your tent support while still giving you room to work throughout their growth cycle? 

Temperature, Light, and Humidity Levels: Keeping It Consistent 


The ideal temperature in tents for weed depends on the stage of growth of the plant. In general, A standard, well-ventilated grow room should be kept between 75-85 degrees Fahrenheit under optimal conditions, but here are some temperature ranges to keep in mind. 

Seedling stage: During the seedling and germination stage, the temperature should be between 75° and 85° F with 70% relative humidity.

Vegetative stage: Marijuana plants thrive in temperatures between 70-85 degrees Fahrenheit (20-30ºC). Do not let your tent exceed over 30 degrees Celsius. 

Flowering stage: It’s best to keep temperatures slightly cooler, around 65-80°F (18-26°C). Cannabis plants like a range of about 65 to 85 degrees Fahrenheit to prevent mold and other issues. 

Growing tip: Be sure to monitor the temperature regularly and avoid temperatures that are too high or too low. Extreme temperatures can damage the plants and reduce their yield.


Arguably, light and humidity are two of the most important factors to consider when growing weed in a tent. Cannabis plants require a specific amount of light to grow and produce buds and the amount of light required depends on the cannabis plant’s stage of growth. A quick rule of thumb:

Vegetative stage: Cannabis plants require 18-24 hours of light per day during the vegetative stage.

Growing tip: Let your plants “nap” for four-five hours in the heat of the day. This will help you control the temperature and not fight the heat by turning the lights off. 

Flowering stage: Marijuana plants require 12 hours of light per day during the flowering stage and twelve hours of darkness. 

Growing tip: Keep your lights off during the day and on at night to beat the heat. Automatic timers are a lovely way to keep your plant’s sleeping pattern on schedule. 

The size of your grow tent and the amount of plants you are growing should be taken into account when selecting a grow light. The best lights include adjustable wattage knobs and dimming settings, but keep in mind that the light’s distance is also crucial. When installing 600 watts grow lights should be about 55 cm away from the plants and 400 watt lights should maintain about 35-40 cm (adjust accordingly).


Humidity is also an important factor to consider when growing in a weed tent. They require a specific level of humidity to grow and produce healthy buds. Check out the ideal relative humidity levels for your grow tent: 

Vegetative stage: Keep your humidity levels between 50-70% during the vegetative stage.

Flowering stage: During the flowering stage, cannabis plants require a humidity level of 40-50%.

Growing Tip: To maintain the ideal cannabis humidity level, consider using a humidifier or dehumidifier. Don’t have one? Watering your plants after your lights are turned on will help you keep humidity levels low while keeping an open water container in your marijuana tent can raise them.    

Growing Tips for a Happy Harvest

Here are some helpful tips for a happy harvest that we couldn’t help but share:

  • Be sure to monitor the temperature and humidity levels regularly to ensure they are within the proper range for a healthy outcome. 
  • Use high-quality grow lights that provide the right spectrum of light for cannabis plants. They also save energy! 
  • Use a high-quality soil or hydroponic systems to provide the right nutrients for your plants.
  •  Prune and top your plants regularly to promote healthy growth, good structure and maximize yields.
  • Use a carbon filter to keep all smells inside the grow tent and maintain discretion.
  • Air circulation is just as important as other factors we have discussed. Circulating fans will not only make your stems strong and help you produce bigger buds, but they will help with pest control too!
  • Ventilation is also a key component when growing in weed tents. Make sure your plants are getting fresh, cool air. 

There ya have it! Grow tents are an excellent option for hobbyist growers or those growing in a smaller space. They are designed to keep things simple and can produce some really beautiful buds! When choosing a grow tent, consider the size, material, ventilation, and reflectivity, these components will ensure that when you’re harvesting marijuana you are producing a quality product. If you follow our step-by-step instructions and remember to be consistent, setting up a grow tent is relatively easy.  Always keep in mind that when growing cannabis in a grow tent, temperature, light, and humidity are the most crucial aspects to take into account. Give your plants the care they need since sometimes a little love goes a long way, and you will always develop a fantastic smoke.
