Let us begin:

What is a Grow Tent? Why Should You Use One?

A grow tent is a designated space inside which you can grow your cannabis in a controlled environment. When it comes to growing your weed indoors, you get a much better control over the kind of light, heat, air and water that you provide to your plants. A grow tent helps enhance that experience. Furthermore, it is also a concealing cover over your cannabis plants, allowing you to place it anywhere in your house without visitors raising a suspicion. There are a number of benefits of using a grow tent, such as:

  • It helps maximize the efficiency of the light with the help of reflective panels inside
  • Weed usually has a strong aroma associated to it, grow tents help contain it
  • They are very useful if you are growing different plants/or plants at different stages in growth cycles as you can bundle them together instead of having all in a room at the same time
  • They are space-saving as well

Why are Small Grow Tents Important?

Let us quickly focus on why ‘small grow tents’ are important. This is because not all growers have large growing needs. Some growers want to grow in smaller batches, or are just starting out and do not want to invest into a big setup. For these  growers, small grow tents are a great option as they occupy less space, cost less and are a great ‘laboratory’ for their experiments. Moreover, small sized grow tents can also be easily moved around without much of a hassle and are quite easy to set up as well.

Things to Keep in Mind While Buying a Grow Tent

Now that you know which some of the best grow tents are, here’s a closer look at things that you need to keep in mind while buying one:

  • Space/Size: The space and size of the grow tent is an important factor when it comes to choosing the ideal grow tent. It needs to be ensured that the tent is sufficient enough to contain all the pots that you want to keep. Moreover, you must also make sure that the tent doesn’t occupy too much space in your room.
  • Light Leakage: Light leakage is a common problem with grow tents. When you set up a grow light inside your tent, the tent must have no space from where light comes out. The more the light that comes out of the tent, the lesser the plants get. To ensure this, make sure the density of the canvas is decent.
  • Reflective Material Used: You must make sure that your tent is lined with reflective material on the inside and that it is a good quality reflective material. The more reflective your tent is, the better is the efficiency of your light.
  • Durability: Your grow tent must also be durable and sturdy. The metal rods that support it must be able to carry a sufficient amount of weight which is needed to hang the grow lights (which can often be heavy if you add reflectors etc).
  • Ventilation: There need to be an adequate amount of air vents so that your plants get fresh air and the still air can move outside. Ventilation is also important to maintain appropriate humidity levels.
  • Zipper Quality: A lot of people have suffered because of a bad quality zipper because if it breaks after a few months, you’ll have to replace it else light will keep leaking out of your tent.
