How many plants in a 3x3 grow tent?
A 3x3 grow tent comfortably fits 2 to 4 large plants or 6 to 9 smaller plants depending on training style and container size. Growers using SCROG training typically run 2 to 4 plants in 5 gallon pots for a full 9 sq ft canopy. Compact setups can pack 9 plants in 1 gallon containers in a 3x3 grid.
How many CFM for a 3x3 grow tent?
A 3x3 grow tent needs an inline fan rated 200 to 300 CFM to refresh the roughly 62 cubic feet of air volume every 60 seconds. Multiply tent volume by 60 air changes per hour and divide by 60 to get your minimum CFM. Step up to 400 CFM if you are running a carbon filter, which reduces effective airflow by 20 to 30 percent.
What size light for a 3x3 grow tent?
A 3x3 grow tent needs 270 to 360 true watts of LED output, or roughly 30 to 40 watts per square foot of canopy. The Gorilla Xi330 at 330W and 837 µmol/s PPF is purpose-built for the 3x3 footprint — its 2'x3' to 3'x3' coverage maps directly onto this tent.
How many watts for a 3x3 grow tent?
A 3x3 grow tent runs best on 270 to 360 watts of real power draw at full power, with 130 to 200 watts typical during early growth stages. Aim for 30 to 40 watts per square foot of canopy. Dimmable LEDs let you dial intensity down when plants are young.
What size fan for a 3x3 grow tent?
A 3x3 grow tent needs an inline fan rated 200 to 300 CFM to refresh the roughly 62 cubic feet of air volume every 60 seconds. A 6-inch inline fan is the standard choice and fits the 11-inch double-cinching ducting ports. Pair it with a matching carbon filter for effective odour control.

With Gorilla, you truly get more grow tent from your grow tent. Elevate your cultivation game.
Size Matters
While many tent brands lean on 3D renders to suggest spaciousness in their tents, Gorilla Grow Tent sees through the illusion. The truth is simple: shorter tents mean smaller plants. Our unique height adjustability ensures you can truly maximize your grow space. This means generous room for professional-grade harvests, a protected and organized space for your gear, and an orderly grow environment. Gorilla Grow Tent offers genuine space for genuine growth.
Strongest Grow Tent
While other brands boast about pole diameter as a measure of strength, they're skirting the bigger picture. True tent strength? It's about material, thickness, quality of welding, and smart design. Pole diameter alone won't cut it. And while they're busy counting millimeters, we're focused on weight capacity. Why hasn't anyone replicated our design? Simple – real quality comes at a price. Here's the thing: it's not just about safeguarding your plants. A tent collapse can bring lights crashing down, posing a real fire risk. Unlike the competition, our tents can handle a whopping 300 POUNDS of grow equipment.
Strongest Zippers

Grow with Gorilla's industrial-grade zippers designed for longevity, ensuring your green sanctuary stays unbreached and your crops remain secure.
