There are a large number of brands which make grow tents – and most of these tents are pretty identical as well. It requires a detailed review in order to understand what are the differences between these otherwise very similar looking products. However, let us first begin by covering the basics about these tents – 

What are Grow Tents?

Grow tents are tents which are lined with special reflective layers on the inside and have a thick canvas layer on the outside. The primary purpose of these tents is to keep light trapped inside and ensure that the plants get the maximum possible benefit out of the lighting. Grow tents give the plants a safe and dedicated space for their growth and ensure that the efficiency of the light is also maximized. These tents are supported by poles around which the canvas is placed. They have zips which can open up and you can keep your plants inside them for growing the plants. 

Benefits of Using Grow Tents for Growing Marijuana

There are a number of benefits of using grow tents for growing marijuana – the biggest of these benefits is the fact that growers can get a private space to grow their weed and they don’t have to keep it in public view. While the legalization drive has hit full-swing, there’s still a lot of social stigma and taboo that surrounds growing weed and people would rather have it grow inside tents, hidden from people. Most growers also attach a carbon filter in their grow tent which will make sure that the smell gets trapped inside and does not leak out.

The biggest reason as to why people use grow tents is that they help ensure that the lighting is proper and that growers can provide their plants with the best and the most optimal lighting. The lights are amplified and reflected on to the plants thanks to the reflective layers inside the tent. The reflective surface makes sure that the plant is getting lighting from all angles and from all sides and that maximum light is reaching the plants. Lastly, grow tents are also very beneficial when it comes to keeping insects and pests away which might damage the plants otherwise if you keep them in the open.

Buyer’s Guide: How to Buy The Best 4×4 Grow Tent?

Consider these points below as a checklist of sorts. Keep them in mind when you are making a decision to buy a grow tent for yourself. 

  • Area Covered by Pots – First do a dry run. Even before you start growing, try by keeping empty pots side by side and see how much space your pots occupy. If they occupy a space greater than 3.75 x 3.75 ft, then you should perhaps look for a tent bigger than 4×4. However, this should be enough for most people growing weed for personal consumption or just trying their hands at growing weed for the first time.
  • DurabilityAnother aspect of having a good grow tent is to ensure that it is sturdy and durable. The tent needs to be strong enough to support the weight of all the things that you hang on it. Grow lights and carbon filters being two of the biggest, but there are some growers who also hang clip-on fans and other grow tent accessories for better growth. Hence, the tent needs to support the weight and be durable enough. Most tents on our list are very durable and can easily hold about 110lbs of weight without any problem.
  • Canvas StrengthThe canvas, which is the exterior covering which covers the poles and actually forms the tent needs to be made out of a thick material. This is because in most cases the Canvas is the part of the tent which is facing the most wear and tear and hence it needs to be strong. The canvas not only needs to be strong, but it also needs to be thick so that it can ensure that the light isn’t leaking out of the tent. The whole idea behind a grow tent is to keep the light to a limited area and if it leaks out it would be quite counterproductive!
  • Reflective LayerYou must also make sure that the inner layer is reflective enough. We strongly recommend to buy only those grow tents which have a reflectability of 95% or more. This reflective Mylar layer on the inside ensures that the light is reflected on to the plants properly. It helps increase the efficiency of the light and the impact of the light on the plants as well.
  • Zipper QualityMany growers who take this lightly tend to face a hard time. Always make sure that your grow tent uses a high quality zipper. Not just the handle, the entire zip needs to be a high-quality one. Zips are often the first part to break or falter in a grow tent since they face the maximum wear and tear as growers open up the tent multiple times a day! Hence, it is critical that the grow tent of your choice has a high-quality zipper on it.
  • Brand CredibilityBrand credibility also matters. This is a niche industry with a lot of players making grow tents. Trusted names such as Vivosun are usually considered to be the best options for growers because you know that they are the ones which are in it for the long run and will provide you with better after-sales service and will honor the warranty as well!
  • Observation WindowsThe best 4×4 grow tents are the ones which come with observation windows. These windows help growers to make sure that their plants are growing well and does not require them to unzip the whole thing to take a look inside – thereby saving some wear and tear on your zip while making it easier to look at the growth and progress of your marijuana plants growing inside the tent.
  • Floor TraysSince you will be working with a lot of soil, water, foliage, and nutrients here, there’s obviously a chance that some of these might spill over and fall down. This is why floor trays are critical because these are the trays which can then be easily taken out and cleaned and placed back so that your tent remains safe and clean.
  • Cost and WarrantyLastly, always make sure you’re spending just the right amount. Set a budget and look for a grow tent in the same budget. The cost can vary too much between the cheapest and the most expensive tent but your budget is an important part of your personal finance so try and stick to it. Then there’s also the warranty aspect. Make sure you buy a grow tent that offers a decent warranty period. Most tents on our list offer at least a year of warranty.

Now that you know what are the things that need to be kept in mind before you buy a grow tent for yourself, we hope you will use this as a checklist and make a well-informed purchase.
