Homegrowers have flocked to grow tents for decades to minimize an indoor garden’s impact on a house while sequestering aromas, promoting plant health, and maximizing yields.

Why use a grow tent?

But benefits aren’t limited to yield. Grow tents are outfitted with fan ports to swap hot, CO2-depleted air for a neutral, fresh breeze, improving a grower’s chances of raising healthy plants. Additionally, by limiting the size of a grow space, filtered exhaust fans scrub the air using far less electricity than they would in an open room—thereby minimizing a garden’s overall power consumption.

Space for your grow tent

Apart from readymade convenience, growers use tents to improve a garden’s efficiency, increase yields, and save money.

Why these particular grow tents?

These are great choices, but instead of growing plants in the open air, I think most people growing for personal use would be happiest with a mid-size tent. This size tent accommodates many popular grow lights and can grow up to about a pound of cannabis per harvest (a mid-size grow tent has dimensions of 2’x4′ or 3’x3′ with a height of 5′-6′).

I think the best way to make an efficient exhaust system is to hang your exhaust fan inside the tent. This significantly muffles the sound of the fan running, and lets you create a relatively straight path from your light to the fan for maximum circulation and airflow.

Light & Smell Check

For both air and water pumps, it makes a difference to place them on something besides directly on the ground. For example placing them on a piece of wood will muffle the vibration.

If you’re trying to create a growing environment from scratch, you may have to do some DIY which can feel overwhelming if you’re just getting a grasp on growing. Utilizing a grow tent takes care of a bunch of environmental factors in one fell swoop.

If you have a smell emergency, you can use an exhaust fan directly attached to a carbon filter sitting on the floor. This isn’t as effective as a “real” exhaust system, but it will clear an entire room of smells in just minutes. Some growers who can’t fit a carbon filter in their grow space have even used this technique to control smells for a whole grow!

Short plants can only yield so much even if they’re completely covered in bud

To get better airflow without light leaks, you can make a little “window” or light trap facing down (using the built-in intake vents) to let air through, but not light
