Grow tents allow you to regulate the amount of sunlight, moisture, warmth, and pressure in your growing environment, allowing your plants to grow quicker and healthier.

Growing your favorite plant species is an exciting activity because you will have something to focus on. But, planting is as hard as taking care of a baby. First, you need to prepare your place and materials to ensure the growth of your plant.

๐Ÿ  Perfect Space

Take a look at every corner of your home. Is there enough sunlight passing through your windows? Is the direction of air goes to your plant? If your answer is 50/50, better make sure that your plant is in the right place. Check if your plant is not reachable to kids or your pets.

It is also great if it is near the window to have fresh air and sunlight for growth. Suppose you think you only have a small space for plants. In that case, there are available grow tents to facilitate the necessities of your plants as long as you monitor them properly. Make sure that it is always in your sight so that you won’t forget that you still have plants to take care of.

๐ŸŒ… Water Supply and Sunlight

Water and sunlight are also essential substances that a plant needs. Generally, plants grow using more than 80% of water as part of their food process and cooling their stems. Hydrated plants affect the color of the leaves and the strength of the branches.

If your plant is brittle and has a pale color, you better give it water as soon as possible. But, remember that do not overwater your plant because they can also experience drowning and death. Just put a good amount of water until the soil is well damped, then wait for it to absorb and distribute the water to its leaves.

It is also apparent to tell if your plant is not receiving enough sunlight. Plants tend to follow the rays of the sun until it thinks that it passes enough to its leaves. Another sign is that the stems become thinner and weaker. Water and sunlight are always a partner to make their food. Of course, there are other needed constituents, but these two affect the plant’s primary food process of photosynthesis.

๐Ÿชด Soil

The soil will be the bed of your plant. It will carry all the nutrients from the roots up to its leaves. Using suitable soil can help the plant thrive. You can also mix the soil with other substances like moss, shredded bark, and high-quality fertilizers. Take note of the important nutrients that your plant needs. Some nutrients needed are phosphorus for proper germination, nitrogen for healthy leaves, and potassium for strong stems.

๐ŸŒก๏ธ Air, Temperature, and Humidity

On the contrary, with humans, plants exhale oxygen and inhale carbon dioxide. Plants always need fresh air to avoid suffocation. So make sure that your place is not surrounded by chemicals, smoke, and other air pollutants that can harm your plant. Temperature also affects the air.

Generally, plants do not like too hot surfaces. They can quickly wither and die if the temperature is too high. This also affects the water content of the plant. A plant produces its own water for some time called dew whenever the surroundings are cold. The dew helps maintain the plants’ moisture, especially at night, so it is better to put a thermometer and hygrometer beside your plant to ensure it has the perfect environment.


>>> As mentioned earlier, grow tents or grow rooms are like the representation of the ecosystem in the outside world. So, you still need to provide the necessities of the plants in order for them to survive indoors.

>>> One important thing that a plant needs, regardless of location, is air. Plants need air, together with other substances, to make food. And like humans, plants also breathe through the surrounding air. So, depending on the type of plant you have, it is crucial to decide where to place your plant to receive enough air for a living.

>>> Aside from these, not all air is beneficial to plants. If a place is polluted and if your plant is weary of its stagnant environment, proper ventilation is needed. Good ventilation, like exhaust fans, will let your plants breathe with clean air and control the humidity around them. Remember that plants need ventilation to grow fast, prevent molds, and avoid being home to some pests.


>>> An exhaust fan is beneficial to plants, especially if they are in a grow tent. This fan blows out the hot air and foul odor while letting the fresh air come into the tent. However, an exhaust fan also affects humidity and temperature. Remember that plants can produce dew that can increase the moisture and build molds.

But, also consider what type of plants you have in your grow tent because there are still plants that love damp environments. Also, because larger plants create more water droplets than smaller plants, you may have to pay a lot of attention to temperatures and humidity as your crops cultivate.

Depending on your plant and the size of your grow tent, you must adjust the exhaust fan every time. Generally, the exhaust fan must run during daylight with regular time gaps to maintain the fresh air inside the tent. Therefore, it is advisable to run the exhaust every three minutes. Take note also of the size of your grow tent. Here are the other factors you need to consider to know when to run your exhaust fan.

๐Ÿ’จ Know The Size Of Your Grow Tent

Exhaust fans are measured by cubic feet per meter. That is why before buying an exhaust fan, measure the total volume of your grow tent, then divide it by three. The answer will be the needed exhaust fan for your tent. For example, if you have 720 cubic feet grow tent, just divide it by three, therefore having 240 cubic feet per meter requirement for an exhaust fan.

๐Ÿ’จ Record The Temperature And Humidity

Also, remember to put a thermometer and hygrometer to know if it is time to operate your fan or you need to turn it off. Every stage of the plant has different requirements. For example, the temperature must fall under 70 degrees Fahrenheit and 65% humidity level for seedlings. If you turn on your tent’s light, it is recommended to turn your exhaust fan on. Lights can still affect the temperature, especially if your tent is placed in a sunny area.

๐Ÿ’จ Observe Your Plants

Plants need carbon dioxide to make food. But without proper ventilation, your tent can accumulate too much carbon dioxide that can harm your plants. To know when to run your exhaust fan, always observe your plants. Signs that it is drowning with CO2, your plants have thicker leaves than usual.

There may also be fewer flower blooms because too much CO2 can deteriorate the essential nutrients for your plants like vitamin C and zinc. In addition, high levels of CO2 can suffocate your plants, so better to monitor the levels by putting in some gas analyzer.
