Benefits of Using a Grow Tent

Using a grow tent to grow your plants has a lot of benefits. The greatest benefit is that it gives you complete control over your plant growth and the growing environment. It also helps you save money in the long run because you’ll need less money to provide nutrients, water, and light for your plants. Other important benefits of using a grow tent are listed below

Total Control over the Growing Environment:

Using a grow tent gives you total control over the conditions needed for healthy and successful plant growth. You can control the temperature, exposure to light, and humidity levels better than growing your plants outdoors.

Enhances Photosynthesis:

Grow tents are built with reflective mylar walls on the inside that retain the light in the room, ensuring that the plants get the best quality of light inside the grow room. The reflective mylar material also helps to prevent the light from leaking out of the tent. This controlled light environment boosts the process of photosynthesis in the room, preventing the leaves from yellowing or getting weak. Since light is much needed to enhance the process of fertilization, the controlled light system in the grow room allows your plants to grow healthily and successfully.

Controls odor:

The reflective mylar material not only helps to keep light in, but it also keeps in the odor produced by your plants. If you are growing marijuana and want to grow it discretely, a grow tent is your best bet. Plant fertilizers have a terrible odor; a grow tent helps contain the smell and prevents it from leaking into the room.

Helps save money:

In the long run, using a grow tent to grow your plants costs less. You’ll require less water, fertilizer, and cheaper supplies. Growing your own cannabis reduces your trip to the dispensary, which can be really expensive, especially if you have to buy weed more than once a week.

Factors to Consider When Buying a 4×8 Grow Tent

There are many grow tents on the market; this makes it difficult to purchase the best suited grow tent. To make this decision easier, below are a few things you need to consider before purchasing a 4×8 indoor grow tent.

Size of Grow Tent You Need: Before purchasing a grow tent, you need to think about the size you actually need. A lot of factors influence the size of the grow tent to purchase, like availability of space and the number of plants you plan to grow. You have to factor in these conditions before deciding on the size of the grow tent you want to get. In this article, we are discussing the best 4×8 grow tents. Setting up this grow tent may require more space than just the corner of your room.

Space Available: The location or area of your home you plan to set up the grow tent is another essential factor to put into consideration when shopping for a grow tent. You have to consider the amount of space you have before getting the best suited grow tent. If you plan to set it up in your room, measure the length, width and height of the area and compare it with the size of the grow tent you want to purchase. Ensure that the space you have can accommodate the size of grow tent you want to buy; in this case, a 4×8 grow tent. It needs adequate ground space and overhead space.

Number of Plants You Want to Grow: This is the main reason for purchasing a grow tent. Your plants need enough space to grow successfully; they need to be spaced out and cared for independently. Before you shop for a grow tent, think about the number of plants or plant pots you want to grow. If you decide to use 5-gallon buckets to plant in 4×8 plants, you should be able to fit about 18 plants in the tent. The height of the plants is also quite important; you need enough headroom for your plants to grow tall.

Ventilation: Air circulation and ventilation contribute to the successful growth of your plants. You need to ensure the grow tent has a sufficient ventilation system. Ensure that the cords and the ducting ports are of the best quality. These play a huge part in the ventilation and airflow inside the tent. There are two basic types of ventilation system, active and passive intake system. The active intake uses two fans to provide a constant and adequate airflow in the tent; one fan blows air into the tent while the other blows out the air.

On the other hand, the passive intake is a one-way ventilation system that blows air out of the tent but not into it. To maintain good and adequate ventilation and temperature, ensure that your tent is set up close to a window or any other opening. This provides enough fresh air for your plants to grow.

Cleaning and Maintenance Tips

  • Before using your brand new tent, use a bleach and water solution to clean it properly. Make sure you do this before hanging your grow light.
  • Vacuum the debris in your grow tent at least twice a week to ensure that insect eggs, fungi, and bacteria won’t have a place to hide.
  • Spray the surfaces of the tent, including the roof and floor, with a bleach solution that is potent enough to kill pests. Use a clean cloth to wipe the surfaces of the tent.
  • Allow the wet surfaces to air dry
  • About 12 – 24 hours after cleaning with bleach, directly apply a 3% Hydrogen Peroxide H2O2 solution to all the surfaces in the tent. You can purchase this at your local store. Put the solution in a spray bottle to make things easy, spray it on all the surfaces, and allow it to air dry.
  • If you notice pests, diseases, spider mites, or powdery mildew in the grow tent, take your plants out of the tent immediately. Then clean it with bleach and 3% hydrogen peroxide solution before returning the plants.
  • When spraying the surfaces of the tent with tent or hydrogen peroxide, be careful not to directly spray the surface of the light bulb as this may damage it.
  • Clean your grow tent with bleach and H2O2 after each harvest. This is to get rid of any pests or diseases before growing a new set of plants.
  • If you plan to reuse your plant pots, clean them before reusing them.
  • Sterilize and sanitize your irrigation system between the growth cycles.
  • The vents accumulate dirt and dust over time. Inspect the vents and clean frequently. You can spray it with bleach to ensure that it’s clean.
  • Intake filters get clogged very easily; this is because they trap contaminants and prevent them from getting into the tent. Replace the intake filters as often as possible.
  • Use beneficial predatory mites to keep bugs away from the tent.
