VIVOSUN S448 4x4 Grow Tent, 48"x48"x80" High Reflective Mylar Grow Tents with Observation Window and Floor Tray for Hydroponics Indoor Plant Tents for VS4000/VSF4300

Very nice tent, it’s been a while since I’ve owned a tent; quality has risen! Those are 5 gallon pots and there’s plenty of room for more. Easy assembly and it’s sturdy. Zero issues and it’s the perfect size for my space and needs. Access zippers on both side, highly reflective, and a viewing window. I was going to save a few dollars and purchase a no name brand tent, sure happy I didn’t. I can easily recommend this tent! The light in the photo is okay, I’ll be getting a VIVOSUN light soon.

I got this today to help keep light out of my room and also house one of my more specialized sundew that need much higher humidity than my desert air can hold (along with 3 more on the way.). Assembly was quick and easy with directions specific for every model. Poles were fastened with plastic holders and packed well. Lighting is incredible inside the tent! The size is perfect for my shelves to easily fit inside along with an evaporative humidifier. It is sturdy, the zippers are EXCELLENT. I wonder if other zipper reviews were from the old model and not this "upgraded sbs zipper" feature? Mine are flawless. I've included a closeup window view of the plants. It's very clear and see-through, not foggy at all. It's holding temperatures and humidity levels very stable and accurately. I haven't fine-tuned it just yet, but am testing various humidity settings. I am VERY impressed with it's performance so far. There is no light leak what do ever. Finally, I can sleep well again, while still being able to lift the flap and enjoy my plants. I would like to test this in an extreme humidity test for 70-90% humidity for pitcher plants.

I LOVE this 60"x32"x80"" grow tent!!! The tent material is thick, heavy duty zipper, the metal bars are very sturdy! I also like it unzips 3 sides of the grow tent. No light leaks either. The corners are reinforced which is not reflected in the picture. I really like there is not a middle horizontal bar around the perimeter, makes it SO much easier to get to a plant in the back of the tent, or pulling one out. Very easy to assemble, I assembled this in 30 minutes by myself including the canvas! The instruction pamphlet was perfect, just look for your specific model. Very happy with this tent. Thank you VivoSun for coming through on a quality grow tent!

Pros: • Sturdy steel frame and thick canvas • Reflective Mylar interior for better light distribution • Multiple vents and cord ports • Observation window & removable floor tray • Great size (true 4x4 footprint with tall height) Cons: • Like most tents, you’ll want to be careful not to snag the zippers • Slight light leaks around the zippers (not major, but noticeable in a dark room) Overall, this is a reliable 4x4 grow tent that balances quality and affordability. If you’re looking to upgrade your indoor grow space or start a solid 4x4 setup, the VIVOSUN S448 is a strong choice.

This surpassed my expectations. It’s very heavy duty with all metal poles and thick lining throughout. It’s not a cheap tent like I’ve seen elsewhere. Had plenty of outlets for stringing cords or other needs through. I’m planning on adding a temperature regulator and heater but, for now I have my citrus plants, grow lights, and humidifier inside with plenty of room. Love the window that I can look through without opening the door and letting the humidity out. Amazing price for the quality.

It may feel a Lil wobbly if you don't have support poles for the mid section. For a tent this size they should come standard. The zippers are always sketchy on tents but not this one. The zippers are the smoothest I've ever seen when used. For those who are upgrading from a 3x3 be aware of the height. Its the best tent I've ever had and this is my 3rd. You can grow 4 dwc plants without any space issues or fear of the flowering stretch

Very easy set up, just follow the directions in the book, look for your tent and follow it. Very tall and wide. Great for plants if you’re trying to have tall n wide out plants. Zipper is low noise level, quality is unmatched vivosun functions really well. And no Velcro as all

This is the first grow tent I have ever bought, so It's not like I'm an old salt or something, but I am quite pleased with what I got for my money. I bought this tent to work as a mother room for cloning my medical marijuana plants. I have a commercial grower's license in my state and I'm trying to build a business out of my home. I've got an extra bedroom that I use for a flower room and a cabinet in the living room that I use to root my cuttings, but I had to come up with yet another place to grow some mother plants and I needed it in a hurry. I got on Amazon and started looking for a grow tent. The most common sizes came in multiples of four, like 2x4, 4x4 et cetera. My home is small and my space limited so a 4x4 was out, but I didn't think that a 2x4 would be enough tent for my situation. So I settled on the Vivosun 3x3 tent and I'm glad I did. The tent is a lot bigger than I thought it would be really. There is ample space for my diy flood and drain system and I feel like four medium plants will be very comfortable inside. I haven't used the "tool holder", but I feel like it may be a nice addition. The tool holder itself does seem cheaply made and I don't know how durable this particular part will be in the long run. As I read on other reviews, the sock tubes for ventilation are very tight. I put a rigid 6" duct coupler through the top hole on the left side and it was quite a squeeze, but I took my time and managed to get it in there without ripping anything. Inside I hung my Vivosun 440cfm fan which I think will provide plenty of fresh air to my moms. Unlike other reviewers, I think that the tube fitting tightly is a good thing. It will help avoid air and light leaks, and provides some small amount of lateral support for the fan itself. When I hooked up my "1200 watt" LED inside I did discover some pinprick light leaks, about a dozen or so on the door of the tent. I can't imagine these tiny holes allowing enough light in for anything and I'm not even subtracting a star for it. You actually have to move your head around and be looking at it from just the right angle to even notice them, and even in today's technological age manufacturing defects are part of life. Perfection is only a concept. Overall the tent seems like a good quality item, and it saved me at least some money and a great deal of time over building a wooden cabinet for my mothers. Only time will tell how well this will hold up but I am very satisfied with my purchase and I can't imagine getting much more of anything, ever for the price I paid. I'm really kind of taken aback with what I ended up getting for my money and I wouldn't hesitate to order another twenty just like it if I needed them.
