  • Fantastic Quality grow tent
Size: 48"x48"x80"
The VIVOSUN S448 4x4 is a well‑built grow tent with a strong metal frame and good‑quality materials that offer excellent durability; I bought mine in 2019 and it’s still going strong. Assembly is easy, and the tent delivers great value for the money. The zipper works as intended, though it needs to be handled gently to ensure long‑term use. Overall, it’s a reliable, sturdy, and practical tent for any indoor grow setup. I use it every year to overwinter my tropical plants and also to have my veggies ready for growing season after the last frost. ... show more

  • First impressions... (we know what they say)
Size: 48"x48"x80"
I cannot believe how much value, the detail and build quality. Once you know one VS product it all makes sense, learning nuances in layouts and designs... and fundamental likenesses, lending to sturdy construction, consistencey and uniformity of all products. I like NO LIGHT LEAKAGE, bidirectional safety. Would love to see camping equipment, what Vivosun could do with a tent ; Super impressed. Like a wardrobe easy to want one of each. ... show more

  • I’m really impressed by VIVOSUN
Size: 48"x48"x80"
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.

  • Worth the money
Size: 48"x24"x60"
Not as large as I would have liked, and the view window could have been bigger. However, the quality is good and the fabric feels durable. It comes with an overflow mat to contain spills. As long as you are not trying to do too much it is perfect. Overall it is a good buy, and I would recommend it for beginner growers. ... show more

  • Fantastic!
Size: 48"x24"x60"
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. ... show more

  • Best Solution for Inside/Garage Gardening
Size: 96"x48"x80"
Ok, so this tent is an amazing alternative for anyone who needs to bring their gardening inside due to inclement weather. It took my wife and I about 20-30 minutes to install. If you are well-coordinated you could do it solo. I don’t recommend trying if your easily frustrated. So let’s go through everything. Price: not the best price or best tent but for the price this is a STEAL! I would choose vivosun over gorilla or other similar brands. Shipping: NO DAMAGE, all parts were present and it got here the day it said it would get here. Setup: 1-2 person job over 20-30 min if you have never set one up. Operation: So, this tent has only been in use for about 2 weeks at my house. So far it is a huge upgrade from my smaller tent. It is durable, efficient, and easily adjusted. More then enough vents to accommodate any situation. One thing I don’t like is the support bars to hang lights/fans from will slide all over the place. That’s fine if you need to adjust your setup but a pain in the kiester if you already have the right set up. Zip ties seem to be doing the trick of keeping the tent poles stable. I don’t think it’s 98% reflective but it’s much more reflective than other products such as panda paper or Mylar boards. Overall, works as advertised and I’m completely satisfied. There are concerns for the zippers. That is on all tents, clothes, or anything that zips. Take your time and make sure you follow the track and you’ll be fine. There was a defect in my tent when I got it, one of the pieces of material designed to prevent light infiltration had been sewn onto the tent. I was able to carefully cut the material away which solved the zipper and function. It took me 5 sec to fix and was 100% common sense. Rules for inside growing are simple... control your temp, humidity, moisture, air, and keep the grow light in and outside light out. This tent accomplishes all of that. If you can’t commit to a room for your growing, this is a perfect solution. ... show more

  • Cat resistant, great quality plant house tent.
Size: 36"x36"x72"
I Love my grow tent. My beautiful houseplants are safe from my cats! Tent is made of thick material with zippers that are easy to open and close. Plenty of openings for airflow. I do use a plant light so my plants get 8 hours of light everyday.

  • Best tent I've had
Size: 48"x48"x80"
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.
