How many plants in a 4x4 grow tent?
A 4x4 grow tent comfortably fits 4 to 6 large plants in 5 to 7 gallon pots, or up to 16 smaller plants in 1 gallon containers for a sea-of-green layout. SCROG growers typically run 4 plants in 5 gallon pots for a full 16 sq ft canopy. The 48 by 48 inch interior supports the widest range of training styles.
How big is a 4x4 grow tent?
A 4x4 grow tent has a 48 inch by 48 inch (4 feet by 4 feet) footprint, giving 16 square feet of canopy area. The Gorilla Pro 4x4 stands 6'11" tall at the base and extends up to 8'11" with the optional 2 ft extension kit. In metric, that is 1.22 meters by 1.22 meters or roughly 1.49 square meters.
How many watts for a 4x4 grow tent?
A 4x4 grow tent runs best on 400 to 600 watts of real LED power draw for full flowering, with 200 to 300 watts typical during earlier growth stages. Aim for 30 to 40 watts per square foot of canopy. The Gorilla Xi420 at 420W and 1,055 µmol/s PPF hits the 4x4 sweet spot.
How many CFM for a 4x4 grow tent?
A 4x4 grow tent needs an inline fan rated 250 to 400 CFM to refresh its roughly 111 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. Step up to 500 CFM if you are running a carbon filter, which reduces effective airflow by 20 to 30 percent.
How to set up a 4x4 grow tent?
Set up a 4x4 grow tent in this order: assemble the steel frame on a flat floor, stretch the 1680D canvas over the frame, zip the door closed to check light-tightness, then mount the inline fan and carbon filter through one of the 11-inch ducting ports. Hang the LED from ratchet hangers on the top frame, run power cables through the 3-inch electrical ports, and set up your climate sensor. Total setup time is 30 to 45 minutes for first-timers.

Tallest Grow Tent

Starting at an impressive 6'11", our tents can soar up to 8'11" with our optional 2' extension kit. Why settle for average when you can reach new heights? 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
Ever wondered why many products conveniently break down just after their warranty ends? As the competition plays the short game, we're going all in. Gorilla Grow Tents are more than just tents – they're your long-term investment. Ditch those delicate zippers that falter under pressure. Grow with Gorilla's industrial-grade zippers designed for longevity, ensuring your green sanctuary stays unbreached and your crops remain secure.
