This tent measures just two feet by two feet wide and four foot tall. With limited height comes limited strain options or you’ll need to know how to train your plants to keep them growing short.

The outer material of the grow tent is made of 1680D thick canvas which is lined with 100% reflective diamond mylar. This reflective coating prevents hot spots and shady areas within your grow area.

Managing your Micro Environment

Best grow tent for growing cannabis. The inside of a grow tent is the perfect environment for growing your cannabis plants. Everything about the tent has been thought of and engineered to support your grow. The tents are light proof providing a discreet lightproof area which also prevents outside light contamination. Yes, that’s a real thing. When your plants are flowering you can’t have any light leakage during their 12 hour lights out period.

The floor of better grow tents is waterproof and removable for easy cleaning and drying. There are entry ports built into the tent which allow you to bring in power cables and ventilation without having any light or air leaks. The inside walls of the grow tent are made of a reflective surface which redirects light back on to your plants which helps prevent hot spots or dark areas.

The confined area of the tent allows for easy ventilation and scrubbing of the smelly air that can be produced by cannabis plants. The ventilation ports allow for air intake as well as being expulsion. Generally, your air is run through a charcoal filter before it exits the grow tent to remove odors.

By keeping your cannabis grow in a sealed area you can control temperature and humidity with much more accuracy thus making it a great place for you to grow your plants. If you were to grow in an open closet or room in your home you would have no way of scrubbing the smell out of the air or to raise or lower the humidity around your plants.

High Quality Grow Tent Poles

Another important item about hydroponic grow tents is making sure you get a tent with enough headroom for growing cannabis. There are many size options available for grow tents. Cannabis is generally a tall plant if not kept. You also need to think about the thickness of your plant lamps and how much distance between your light and your plants is needed. If you add all this space together you are generally looking at 24 inches or more. That’s 24 inches of lost growing space. Do yourself a huge favor and get the tallest grow tent available. Grow tents of 72 inches or higher are best. Generally, 80-inch tents are the tallest available and a great choice for the urban farmer.

The Advantages of Grow Tents

As mentioned above, apart from total control, grow tents offer more advantages than just growing plants in a spare closet.

  • Grow tents are fantastic for pest control. It makes it much harder for pests to get a foothold on your crops when the crops are sealed away safely.
  • The reflective 600d mylar covering of the inside of a grow tent lowers your need for light energy which in turn lowers your electricity bill. That reflective coating prevents hot spots and helps spread light evenly around your grow area.
  • Some cannabis strains release a greater concentration of odors. Without the tent, there is no way of containing and scrubbing those odors from the air in your home.
  • A growing tent also circulates air extremely well, which brings fresh air to your marijuana plants that contain the carbon dioxide needed for strong, healthy growth. Hydroponic grow tents are designed so you can use a carbon-filter air purification device to scrub odors from the air. The integrated system takes air from outside of the tent that brings the CO2 to the marijuana plants, and a carbon filter removes the odor from the air and disperses the scent-free air outside of the tent. This is referred to as ‘negative pressure,’ and it’s shown to be unbelievably reliable at keeping the air inside a grow tent pressurized so no odors can be released or “leak out” while giving fresh CO2 to the garden.
  • Have a water accident? The waterproof floor and walls of a grow tent won’t be destroyed by water. It also makes it much easier to dry up water or clean up spills by removing the floor of your grow tent for a deeper clean.
  • You never have to worry about flowering your plants. During the 12 hours of darkness per day that is required to flower your cannabis plants, it is imperative that no light is leaked into the grow area. Any light during this 12-hour period could stop the flowering phase or even worse produce hermaphrodite plants which produce seeds and buds.

So, to follow up the advantages of growing in a tent are:

  1. The tent magnifies and reflects light to your plants more evenly
  2. It adds a protective barrier against pests
  3. It allows you to control airflow and fresh air to your plants
  4. It helps make you grow more power-efficient
  5. It helps you remove odors from the air
  6. There are many size options for the urban farmer looking to have the thickest and strongest grow

Now that we’ve told you why you should be growing with a grow tent we are going to go over the top grow tents and what makes them great. This is intended to help you decide when purchasing a grow tent. We will review the grow tents that we have tested by size grouping.

Remember that one of the most important factors in choosing an indoor growing tent is the height of the tent. Make sure you pick a tent that is generally high enough for your plants and lighting system. Get a tent tall enough to grow big fat juicy cannabis plants. If you do plan on using a shorter tent due to space limitations you can “train” your plants to be short and still grow large buds.

How to choose the right size to grow tent

Small Growers – People looking to grow one or two plants at a time from seedling to flowering will need a tent at least 2’ x 2’.
Medium Growers – People who are looking to grow up to 4 plants will need a grow tent at least 4’ x 4’ feet.
Larger Growers – People looking to grow 8 or more plants at once will need a tent at least 5’ x 5’ feet.
