Grow tents by Mars Hydro are popular with home growers because these sturdy tents are moderately priced while delivering the array of standard grow tent features, made with some higher-quality materials than comparably priced tents. In particular, the all-metal frame and thick canvas shell add to the durability of this brand’s grow tents, putting Mars Hydro among the best choices out there for your indoor gardening setup.
Mars Hydro grow tent kit features
Mars Hydro grow tents are designed with the growing experience in mind, and they’ve taken steps to compensate for drawbacks that can happen with any grow tent. Zippers on these tents have an extra layer of coverage, the heavy-duty tent fabric and all-metal frame contribute to a stable tent that outcompetes brands with thinner fabric and plastic frames that won’t last quite as long. Observation windows, double-cinching ducting ports, and diamond-patterned mylar reflective inner lining are other features that make this one of the best grow tent market contenders. Let’s look at the design in more detail!
heavy-duty density fabric
One of our favorite features of this tent is the heavy-duty fabric of the outer shell. How thick the fabric is makes a difference in how efficient it will be in keeping your internal conditions inside of the tent. A dense fabric is a tight weave, which doesn’t allow as much air, light, or humidity out. A dense weave is also more tear-proof than a thinner fabric, and it’s more difficult to puncture. Mars Hydro tents are made with 1680 D (D for denier [pronounced din-eer], the width of fabric thread), while more average tents are made with 200-300 D, a thinner fabric that is more prone to pinhole light loss and ripping along the zipper.
diamond mylar inner lining
Mars Hydro tents are lined with a diamond-patterned mylar that reflects and redistributes light more evenly and efficiently than smooth reflective fabrics. A solid tent lining would absorb light, but mylar, which looks like aluminum foil, sends extra light back in the direction of the plants. The canvas has a waterproof lining that helps keep humidity and spills inside the tent. Mylar itself is waterproof as well, making it difficult to stain and easy to clean.
all-metal construction frame
The all-metal frame really makes a big difference in the durability of this tent in comparison to tents that use plastic poles and/or plastic connectors. A metal structure won’t crack or bend nearly as easily, and they can hold more weight than plastic frames. Most models are made with steel, while the largest ones are made with iron and are able to support over 200 lbs. It’s better to have that extra weight capacity than too little to be sure your valuable grow lights and ventilation systems will be secure when installed.
double-sewn zipper stitching
Mars Hydro pays attention to its zippers, which we appreciate because zippers are the part of any tent that gets the most wear and tear. Double-sewn edges help decrease pull on the surrounding fabric, adding to a smoother and more durable zipper. The tents also come with an external flap of fabric that covers the zipper line, keeping the light inside and reducing the potential for light to escape through the closure.
observational window
The observational window integrated into most Mars Hydro’s tents is a common, but important, feature among grow tents, allowing you to peer into the tent without opening the door. Sometimes it isn’t necessary to actually get into the tent, especially if you’re just checking to make sure things are looking good and nothing needs to be adjusted. The less frequently you have to disturb the temperature and humidity level in the tent interior, the better!
waterproof floor tray and tool bag
Tents come with a mylar-lined removable floor tray that makes keeping the tent clean a little easier. It catches spills and is water-resistant, so it’s easy to empty out and clean as necessary. Tents also include an interior tool bag to help you stay organized and keep your essentials in one place.

common questions
how to set up Mars Hydro grow tent?
Most tents you can buy on the market can be assembled by one diligent person, with the exception of the biggest models which may require a second hand. Mars Hydro tents are easily assembled, with poles sliding and snapping into place by connectors. The frame can then be put in the canvas shell, which will wrap around and snugly fit. The directions will be your friend if you get stuck!
how long do Mars Hydro filters last?
Mars Hydro carbon filters last about as long as other filters do on average, which is 18-24 months of continuous use. Changing your filter regularly is important to keep any odors from accumulating in the tent or from being exhausted into the room where the grow tent is located.

Marquis *wants* to know how to keep happy and healthy plants, but had a hard time finding information that wasn't written by just another copywriter. After nearly losing one too many plants, it was time to take matters into her own hands. A team of plant scientists and nursery hands was brought together and The Indoor Nursery was born.
