Here are few must to know factors and features of the VIVOSUN Grow Tents.

Vivosun Grow Tent Materials:

When it comes to grow tents, one shouldn’t compromise with the quality of materials. Yeah, it plays an essential role in your growing process.

Usually grow tent outer materials are made up of Oxford canvas. However, one needs to consider the density of canvas material as well.

The thicker the canvas, the better the lifespan. Also, thick canvas material helps in preventing possible light leakage from your grow tent.

The good thing here is, VIVOSUN Grow tents use 600D canvas which is dense and thick.

Moreover, VIVOSUN grow tents are completely tear proof, and double stitching prevents any air or light from escaping.

Assemble your VIVOSUN Grow Tent:

Upon delivery the box contains separate parts that need to be assembled manually.

However, you shouldn’t panic as the assembly is pretty easy. Also, in the box, you’ll get the instruction booklet where all the steps are described in the visual form.

Also, to make things easy, here’s a video describing entire process of assembling a vivosun grow tent.

Sometimes you just need someone to visually walk you through.

Vivosun Grow Tent Frame:

Your Vivosun grow tent will come with metal poles, and tool-free connectors. VIVOSUN doesn’t feature a fiber or plastic frame structure like other grow tents. The metal won’t bend or snap if kids fool around and knock into the tent.

The frame is going to act as a backbone to your entire grow tent structure, and you shouldn’t compromise with its quality and reliability.

Many people get stressed just thinking of assembly, but the free pole connectors make assembly hassle free.

This image describes perfectly how it’s better than the normal grow tent frame structure.

It makes your overall grow room setup fully stable and also provides the necessary strength to keep things well balanced. Also, it justifies its value as one of the best grow tent on the market.

Vivosun grow tent reflection and seal quality:

As we already stated, VIVOSUN grow tents are built using some high-quality materials. The interior of the tent is lined with reflective Mylar. This fabric reflects around 98% of the light to your plants. This is one of the main benefits of grow tents is that they utilize and reflect all the light released from your grow lights.

If you’re using one of the Best LED Grow Lights on the market, then a combination of these both tools could create wonders regarding outcomes. Also, there is not a doubt in that.

Above that, Stitching and Zippers are high quality to prevent light leakage. The grow tent cover is double stitched and doesn’t leave a chance for light to escape.

Vivosun owners have reported high satisfaction rates with this grow tent, which is why we decided to review it exclusively.

Vivosun Safety Parameters:

You have to be concerned about safety because heat is one of the most dangerous things you’re going to deal with while growing indoors.

This is one factor we don’t usually consider. However, failing to consider this factor can sometimes result in unexpected disasters in your house.

Yeah, Sometimes due to lack of resistance towards heat, the fabric used in grow tent could catch up a fire.

Agree, it doesn’t happen often but in some of the cheap grow tents it’s a possible issue according to experts.

We’re glad to verify it here in this VIVOSUN Review that it’s completely shielded against heat.

The materials in your Vivosun are completely resistant against even high amounts of heat. As we already stated, the materials are made up of high-quality fabric. Yeah, you can count on it as one of the best indoor grow tents.

So, from the safety point of view, Vivosun satisfies all concerns.

Vivosun ventilation and exhaust duct:

Vivosun grow tents have multiple vents that you can control to your plants’ needs. The vents are adjustable with draw strings, so you don’t have to worry about them leaking. Ventilation is a matter of concern while growing big and healthy plants. Your grow space will contain some heat-generating tools like grow lights and fans. In such an environment, it’s common that grow spaces heat up quickly. But this grow tent has enough vents to keep your plants’ environment perfect.

If you’re still using conventional lighting such as HPS or MH, temperatures can get out of control sometimes. That’s why we recommend LED grow lights. Not only do they run cool, but they save a lot of energy. If you choose to get a fan for your grow tent, check out my guide to grow tent fans, carbon filters and installation.

If you’re looking for a fan to match up with your tent, Vivosun offers a line of affordable inline fans that hook right up to the ventilation ducts on their grow tents. If you’re looking for an easy add-on fan for your grow tent, you can find vivosun inline fans here.

What size fan for Vivosun 4×4 Grow Tent?

I wrote an article about grow tent fans where I calculate the fan size for 4×4 tents as well as other size tents. You’ll need a ~200cfm fan for a 4×4 grow tent, and I highly recommend the modern, well priced AC Infinity T4. It doesn’t come with ducting but that’s a cheap easy to order accessory, and you can get it at the same place (Amazon).

Vivosun grow tent sizes:

This is yet another advantage of choosing vivosun as your helping hand for It’s available in several sizes and fulfills almost all of the most recommended size requirements.

The most popular selling variant 48”X48”X80” is their best selling model on Amazon. It’s the most recommended and widely used grow space size for a beginner or a professional.

However, This Vivosun Grow Tent Review is the perfect place to mention that it’s also available in 96”X48”X80”, 48″x24″x60″, and 60”X60”X80”.

In case you’re planning to buy a grow tent for marijuana cultivation then we’d recommend you to go for a 6’ high grow tent as the plant will be taller compared to other veggie plants like tomatoes and so on.

Regardless of which variant you choose, the only difference will be size. All other features will be the same through the different size options.
