Mars Hydro Grow Tent Review: Is It Worth the Purchase?

Are you looking for a grow tent under $100? Looking at the Mars Hydro as one of your indoor grow tent options? Need to find more alternatives to the Mars Hydro grow tent?

I’ve got these questions (and more) covered in this full guide and Mars Hydro grow tent review. I’ll talk about its build quality, materials included, setup, and the price/value for money.

I’ll also give a few alternatives to the Mars Hydro grow tent and answer the most commonly asked questions about it.

Mars Hydro Grow Tent Overview

While there are many ultra-cheap and wildly expensive grow tents, the Mars Hydro grow tent lands somewhere in between.

They offer different tent size options, from a 2’x2′ small tent to a larger tent measuring 8’x8′ that can fill up a small room. The grow tent model I’ll be reviewing is the 2’x4’x6′ variant.

The Mars Hydro grow tent is WELL-BUILT and comes with the basic tools and materials necessary to set up a grow tent.

There’s also a full tent kit version, which I’ve included in the alternatives below. After the tent kit review, there’s also an alternative with similar features to this one.

Company Background

Mars Hydro was founded in 2008 by Mandy Hu in Shenzhen City, Guangdong Province, China. The company originally made LED grow lights but expanded to other products like Mars Hydro tents.

Mars Hydro eventually expanded its business to warehouses and repair centers in the US, Canada, UK, EU, Russia, and Australia.

Where Was it Manufactured

Mars Hydro has research, design, development, and manufacturing plants in Shenzhen City, Guangdong Province, in China. Therefore, Mars Hydro tents are made in China.


The set-up and assembly instructions for the Mars Hydro grow tent is EASY TO FOLLOW. The bars use spring-loaded snap pins for a simple and toolless assembly.

This means you don’t need any tools to set up the tent, only the instructions and a bit of organization to make the process go faster.

You can easily set this grow tent up within 30 minutes from unboxing to completion.

Build Quality

The build quality of the Mars Hydro grow tent’s structural bars is adequate. But I think it could be built better. While they have an all-metal frame, they are hollow inside, making them a bit flimsy.

One good effect of this is that it’s VERY LIGHT, which makes it easy to break down and transfer.

The Mars Hydro grow tent claims to have 110 pounds of hanging weight, but the cross bar’s hollow construction doesn’t inspire confidence.

While hanging a LED grow light didn’t result in the bar bending or breaking, I wouldn’t suggest putting an overly heavy LED light inside.

On the other hand, the zipper seams and zipper flap, as well as the corner adapters, are built very well and feel like they will last for a long time.

Materials Used

The diamond mylar inner lining is one of the STANDOUT FEATURES of this Mars Hydro grow tent. This mylar lining is reflective and diamond patterned to help reflect light.

This prevents light leakage and light loss by reflecting it back into the grow tent and onto the plants. This can help stimulate plant growth more than if the light leaked out.

This is important in growing cannabis because getting enough light is CRUCIAL in its growth stages. This makes the Mars Hydro a great grow tent for growing cannabis.

It also has a waterproof lining to keep the humidity inside and ensure the plants don’t dry out. The Mylar itself is hard to stain and easy to clean due to it being waterproof too.

Price and Warranty

The price point is where the Mars Hydro grow tent really shines. It’s priced between $89.99-$139.99 depending on where you buy it from, which is a GREAT VALUE.

For any green thumb, you’ll want to check the Mars Hydro grow tent out. It’s a great option for both a new grower and an expert.

Mars Hydro also has a 5-year warranty which is long enough for you to make full use of the tent and will last more than a couple of growing seasons.

They also offer a 30-day money-back guarantee where you can have it refunded if you’re unsatisfied with the unit you receive.

Availability/Where Can You Buy

You can check out the Mars Hydro grow tent at Amazon and from Mars Hydro’s website. Periodically check to see if they come out with discounts or promos.

Features of the Mars Hydro Grow Tent

Next, I’ll discuss the features that stood out to me when reviewing the Mars Hydro grow tent.

Diamond Mylar Lining

Diamond Mylar Lining

This highly reflective lining makes the Mars Hydro grow tent lightproof, meaning even if you’re fully blasting your lights outside, the inside will still be pitch black, and vice versa.

Light from grow lights will bounce around and be reflected back onto the plants, which makes unwanted light bleed outside NON-EXISTENT and gives the plants more light for growing.

Although the material feels cheap, it performs its intended purpose very well. If feeling cheap is a trade-off for being lightweight and effective, I’ll take that any day.

It also has a double-layer lining, which helps keep light in, makes it tear-proof, and keeps air and any skunky smell from leaking.

Velcro Viewing Window

The next standout feature is the velcro viewing window. It allows you to see the status of your plants without completely opening the whole tent.

It can also be used as an additional ventilation outlet to let extra sunlight in.

Ventilation and Power Outlets

The tent features several openings that can be used for PROPER VENTILATION. There are two on the sides and one on the ceiling if you want to put a carbon filter.

The two openings on the sides can be used for installing a circulation fan, intake fan, or exhaust fan.

Hanging Bar

Hanging Bar

The hanging bar itself is made of metal poles. While they are made of an all-metal frame, they are hollow. It won’t be as sturdy as a solid metal bar.

The bar is rated for 110 pounds holding weight, and hanging a LED grow light from it produced no issues.

However, I wouldn’t recommend using other lights, especially if they add much more weight to the bar.

If you want to be safe, you should use the Mars Hydro TS1000 — a LED light you can purchase from Mars Hydro. It should be 100% compatible with the hanging bar.

Hanging Pouch

A hanging pouch is included in the box, which is useful and convenient for storing things inside or outside the tent.

If you choose to have the hanging pouch in the tent interior, you can include things like a spritz bottle, small nutrients, or similar items.

It can also be hung with the pouch facing outside the growing environment for EASIER ACCESS.

Access Ports

The Mars Hydro tent features ports at the sides near the bottom where you can run electrical cords, an ethernet cable, or water lines.

Proper and tidy cable management is IMPORTANT in keeping tent kits clean and safe. You don’t want the wires coming into contact with the grow lights.

Additionally, it has the standard air vent and air filter ports to circulate cool air and let hot air out.

Alternatives to the Mars Hydro Grow Tent

Before you go out and buy the Mars Hydro Indoor grow tent, you should check out some alternatives that might fit your needs better.

Full Kit – Mars Hydro Grow Tent Kit
