Gorilla Grow TentPro 4' x 8' x 6'11 to 7'11 w/Included Extension Kit - Tallest Premium Indoor Grow Tent, Thickest & Most Durable Gorilla Canvas, Strongest w/ 300lb Hang Capacity, Hydroponic Grow Box

This is a great tent. Very heavily built, with excellent design and materials. (Note that the tent pictured is a 4X4 tent, not the 8X4.)My only actual complaint about this tent is that they could have used better sippers. These sippers are very heavy duty, but have a tendancy to to sit flat, which can make them hard to zip. I've developed a technique to help, but it's still occasionally frustrating. Just get YKK and be done with it!There are minor pinhole punctures on the stitching that are not light tight, but this is a VERY minor problem. I have about 100,000 lumens in my tent, and if the grow lights are on, and the room is pitch black, I can make out a few of the stitch lines if I've been in the dark for a while. Which means that this tent would probably be OK outside in full-sunlight, which it isn't. Standing inside the tent with it entirely sealed and dark, and room lights on, I had to sit in there for about 10 minutes before I was able to see any light at all, and even then, it was very faint. I feel perfectly comfortable turning the room lights on when the tent is in it's night cycle.Otherwise, this tent is the best I've used. the air-flow design options are awesome, as are the power and water. I even did pull-ups from the top support beams. (Note, check which beams are the load-bearing beams before you do this. My friend did the same thing and bent the joint slightly, but he's 200 lbs, and did it from one bar, not the support bar. He barely bent it, it he subjected it to WAY more than the rated weight, which is 300lbs for the roof, split among 4 load-bearing beams, for 75lbs per beam. He put 200 on a single non-load bearing beam, and barley bent it. This is a solid tent. It even has enough lateral strength that with 8 10-gallon pots full of moist soil and 8 3x3 foot plants, and all the lights, I am able to slide the entire tent across the floor if I push slowly on the bottom. Can't ask much more than that. I added a plywood floor treated with garage floor sealer to make sliding pots around easier, and that probably also helps with the lateral slide.

I think this Gorilla Grow 4 x 2 tent is an ideal size. Whether you are running just one tent or many, this size allows really great access to the whole plant or plants.The quality of the materials used to create the tent is unsurpassed. The framing structure has the strongest and heaviest load capability of any tent I’ve owned with the load capacity of 300 pounds. I’m an older gentleman with arthritis in my hands, and the large pull- tabs on the zippersare greatly appreciated. The zippers are extremely high-quality, and I have not have any issues with the zippers themselves having any failures. This latest 4 x 2 tent has some upgrades and reinforcements to the main zipper on the front door of the tent. Reinforced tabs were added to the bottom. A great addition! It’s much easier to get the zipper started now.This brand was the fourth one I tried after three previous brands had failed. They are worth the price! I converted everything I have to Gorilla Grow tents after my experience.Different things grow at different heights with different maturation times, and having several tents of this size allows me to grow different things and not worry about where my light is placed within the tent.

Know what I'd appreciate more than a free extension kit? A METAL zipper, a FUNCTIONAL zipper, an APPROPRIATE zipper.This tent's pathetic plastic zipper truly is its weakest link, and it's a real shame because other aspects of this tent are solid. It's made of hefty durable material and it's full metal frame can hold more than you'd ever need it to. Better yet, it ALMOST blocks out all light...EXCEPT where the pathetic crappy plastic zipper broke in multiple places on its FIRST zip. I could physically see that a few teeth were barely secured on and lacked the metal housing the other teeth came with. What a joke for a $400 tent. I am beyond disappointed.These guys have you by the family jewels and they know it. Try finding a heavy duty tent with similar specs (like being able to hold a ridiculous amount of weight and lacking crappy plastic pole connection corners). Speak up people, this is highway robbery. I saw the reviews and took a chance, so shame on me, but shame on them for not fixing such a SIMPLE problem to address. Oh, yeah, and have fun shipping this product back if need be.Simply put, this tent has a SERIOUS design flaw, and any customer considering buying this product NEEDS to understand the tent they receive might be spitting out teeth and leaking light regardless of care taken. Maybe you'll be the lucky one? <----- not how this stuff should work.UPDATE 10/7: I got sent a replacement tent. The first one had too short of walls so that the zipper broke. The second one has the OPPOSITE problem! It is so loose that the walls bow in twice as much; I've spend $50 installing a wire frame to correct this problem. I then had to spend another $25 to buy more velcro strips, since loose walls create creases in the zipper's protective flaps. Likewise, I've had to tape up BOTH velcro windows since they let in light like nothing else. Also I've had to stitch up multiple duct ports, and the tent leaks light everywhere - when the light is on, I can see pinhole leaks everywhere along the stitching up top...like hundreds. Wow. Other than than, I have to say, this tent incredibly, incredibly durable. Still, you shouldn't have to do their job for them. Not buying Gorilla again, until they start living up to their promises.UPDATE 4/22: I ordered $130.00 worth of side wall bars to prevent the walls from bowing in. Guess what? The right side ISN'T actually 4 feet, so I couldn't install the bars. This product has no place on Amazon: Amazon is customer-centered while Gorilla clearly is profit-oriented and cares little about quality control or taking responsibility. Take action, Amazon, and protect your customers by denying companies like this from conducting business on a customer-centered platform.

Incredibly satisfied with the superb quality of this grow tent! It's frame is sturdy and the cover is not only durable, but highly reflective as well - so much so that I actually need sunglasses to tend my plants! Would buy again if I'm in the market for another tent, and would highly recommend over the cheaper tents you could buy (although it's not sold anymore, the hortipots brand tent I have pales in comparison, and the GGT doesn't have the same stupid support bar that runs across the center of the floor)!
