The tent without the height extension weighs around 40lbs and can be easily transported from one place to another without much hassle. The tent has a solid steel interlocking frame which can support up to 500lbs. The poles have a diameter of 19mm. The tent boasts of the thickest canvas with a thread density of 1680D which is the best in business (approximately 9x times denser than the standard ones) with diamond reflecting interiors that enhance the efficiency of the tent to a great extent. The diamond reflective surface redistributes up to 30% more lumens creating less waste. Above all the infra-red blocking roof keeps the surface temperatures cool.  It has large EZ view windows so that you can keep a watch on the plants without compromising on the environment within, a large door for easy accessibility, 6 large 11” double cinching ducting ports and two 3” electrical ports.

Lastly it has bug resistant filters so that you can eliminate any risk of bugs attacking your plants. Easy to assemble, the Gorilla grow tent is not very cheap but it is worth every penny of it with the features that it has in store for you.

Apollo Horticulture, which is more famous for manufacturing some of the best grow lights available, has a 3×3 grow tent that is equally popular and has been appreciated by all. Much cheaper than the Gorilla Grow tent mentioned before, this grow tent has a base of 36” by 36” and has a height of 72”. The grow tent has a solid metal interlocking frame that brings sturdiness and strength to the structure. It has thick 600D canvas which may not be as good as the one in the Gorilla Grow tent but is of a decent thickness if you compare it to industry standards.

The canvas is double stitched for added protection and along with the presence of heavy duty zippers prevent light and odour from leaking out while ensuring the durability of the tent. The interior walls bear a 100% reflective and tear proof mylar lining. It is not only light proof but also enhances the intensity of the lights by returning 92-97% of the light from the grow light back to the plants and retains the temperature of the grow tent for optimum plant growth.  The Apollo Horticulture tent has a large removable floor tray to take care of the spills.

The metal frame comes with three additional heavy duty support bars and four metal rings to hang lights and other equipments.  The outer oxford canvas material has a thickness of 600Dx300D and has an inner reflecting mylar lining which has a 80-85% reflectivity. This may be matter of concern to some who are accustomed to a 100% reflective inner lining. It has a large D-shaped door with an attached hook that holds the door open while you work.

The double zipper flaps, the double ducting closures and the double enforced seams all add up to the different protective sealing that are maintained to ensure complete leak proof environment.

Best 3x3 Grow Tents Buying Guide 2019

SIZE:

Though we would be dealing with 3×3 grow tents in this article, but there are a wide variety of sizes with different combinations of base dimensions and height to suit your growing needs. While deciding on the size of the tent, you should take into consideration the number of plants you are planning to grow, the type of plants so that you know exactly the size that they would grow into or in other words you would like them to grow into. The height of the tent chosen should be slightly more that the height of the plants you wish to achieve. The distance of the light from the canopy as well as from the growing plants should determine the height that should be settled for. Though most of the 3×3 grow tents have a standard height of 72”, some manufacturers provide an option of increasing the height of the tent by stacking.  Ideally a 3×3 grow tent suits the growing needs of 2-3 plants comfortably.

STRENGTH OF THE FRAME AND WEIGHT LIMIT:

The basic structure of the grow tent is achieved by the frame. The frame is generally made of steel tubes that are snapped to each other or with the help of corners and connectors. The material of the frame as well as the connectors or corners used determines the strength of the frame. It also determines the weight that a particular frame can withstand. The weight limit which is the maximum weight that the frame can hold should be more than the combined weight of the equipments that you desire to use. The weight limit can also be increased by using additional support or by distributing the weight.

REFLECTIVE CANVAS THICKNESS:

The durability of the tent largely depends on the thickness of the canvas. The canvas thickness is determined by the thread count. The more the thread count, the thicker the canvas and more is its durability. The thickness of the canvas is measured in terms of denier, which is a measure of the linear density of the fiber. The canvas thickness may vary from 210D in the least thick canvas to 1680D in the thickest one. Though all tent canvases are lightproof, the thickness also decides the amount of insulation that the canvas provides. Tents that are placed indoors may not require very thick canvas compared to the ones that are placed outside.

REFLECTIVE MATERIAL:

The quality of the reflective material that provides the inner lining to the canvas is extremely important. It not only reflects the light to make it uniform throughout but increases the energy efficiency as well as the effectiveness of the grow tent. Tents with mylar reflective interiors with 100% reflectivity is what you should look for. Some tents also have diamond shaped patterns in the reflective material that increase the effectiveness many folds.

ZIPPERS:

The zippers may be a very small part of the tent but nonetheless one of the most important ones. This is because they are the ones that are most operated and undergo the most wear and tear. Zippers should thus be very durable so that they do not give way easily and make way for leakage of light.

NO LIGHT LEAKAGE:

The tents should be completely insulated from external light entering the tent or light from the tent leaking outside. So all the openings like corners or zip draws should have overlapping Velcro flap seals so the light leakage is restricted and the efficiency of the tent is maximized.

CORD PORTS, DUCTING PORTS AND WINDOWS:

Most grow tents are equipped with three types of ports, ventilation, exhaust and cord ports. Ventilation ports are flaps sealed by Velcro that are lifted to vent out hot air. Exhaust ports on the other hand are meant to vent out excess light and they typically have one intake and one out-take port. The third variant as the name suggests is the port through which the cords enter the tent. All these ports have to be sealed so that there is no leakage of light through anywhere. The best tents are supported with double-cinching ports that completely block light leakage. The position of these ports is also very important and should be in accordance with the place where you are going to keep the tent.

ADDITIONAL FEATURES:

Additional features that you may look into while buying a tent are flood trays (that take care of water or nutrient solution spills), viewing windows (used to check the growth of plants), tool pockets (to keep the essential tools in one place) and net trellis (if your plants need a lot of support).

Now that we have given you a fair idea about that factors that you should consider while buying a grow tent and the ones that should influence your decision and how, let us have a look at some of the best 3×3 grow tents available in the market.

CONCLUSION:

So by now you might be having a fairly good idea about the 3×3 grow tents and what you should look for when you are set for getting one for yourself. Most of the grow tents that have been mentioned in our list of 3×3 grow tents are of similar quality, but if you are looking for something to last you pretty long and you are not looking to upgrade it in the near future, and if spending a few bucks more wouldn’t hurt you much, then the Gorilla Grow tent is the best and you can not find an alternative to it.
