S448 4x4 Grow Tent 48"x48"x80" Mylar Tent for Indoor Plants | Smooth Heavy-Duty Zippers,100% Reflective Mylar Interior, Robust Steel Frame,Removable Floor Tray,Easy View Window

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.

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 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.

Pain to assemble and poor instructions but otherwise good. Instructions include multiple models with no 5x5 diagrams. The Zipper can get stuck on the lightguard lining it real easily and be a struggle to get out. But not near the door part. Lots of space a good expansion from smaller tents.

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!

I bought this tent in July 2021 I am writing this review today July 2026 . The tent has been in use continuously since the day it arrived. In greenhouse exposed to the sun. I can't enough about how good it has been I have to buy a replacement today due exteror to sun damage. It has been well worth the money a great value. Thank you Vivosun.

These are amazing tents, I had 2 for 3+ years. They are quite sturdy, plenty of openings for vents, wires, durable. Couple of issues I had 1. With enough spills and standing water under the saucers, the floor tray kinda falls apart. Top layer peels off and it soaks through to the floor. I wish they were selling replacement floor trays, but can’t find them other than as part of the whole kit. 2. On one of my tents the zipper catches on to the material covering up the zipper all the time. Annoying having to remove it, but otherwise the zipper still is functioning fine after 3 years. Apart from the tent itself, I was not able to use it without the ductwork/filter/fan, plants were getting moldy/wilting, so had to get all that; I don’t have clip fans, but probably a good idea to add - for better ventilation and to promote auto-pollination for self-pollinating plants, I was a bit worried that too much load is sitting on one outlet - fan, 2 led lights, sometimes I add bug zipper for ground gnats. This is a great year-around indoor entertainment for someone enjoying gardening; I know some get it for other purposes, but I’m not much interested in that. The ability to grow your own organic vegetables in winter is quite fun.

Although this is my first grow tent, I find it to be overall an excellent piece of equipment. It is easy to see where other manufacturers could really skimp on the materials and design, but this one seems extraordinarily durable. Having a friend help set it up is easier, but I can see this as a one-person project to be entirely do-able. The Interior is completely reflective, including the flooring. I really like that the reflective surface is textured, because it seems to "scatter" the light rays more effectively. I have been growing lettuce, tomatoes, cucumbers, Kale, and swiss chard thus far, and it seems that plant growth is very even. Something definitely worth mentioning, since it was not stated in the description I saw, is that they include a second removable bottom with a water-tight 5 or 6" lip around the border. Picture it as a large, custom-fit, flexible tray which will provide extra peace of mind by way of containing an unintentional hydroponic flood. The frame is really simple but strong. One thing is that the instructions for assembly could've been more thorough. For example, there was nothing in the box which told me how to arrange the cross-poles in the top, from which the lights hang. Doesn't take a rocket scientist to sort out the best configuration though. I have already used the zippers a ton, and they still look new. Excellent choice for the material on these zippers, because they slide easily and have a nice, tight closure. I guess this is where people feel compelled to talk about light-leaks, but I don't even need to go there. Any tiny, errant pinholes of light are so negligible, I don't even give it a second thought. And I fully understand the consequences of light exposure during the dark hours. I really really like having the ability to actually step into this tent and walk upright around the periphery of my plants. It's also a neat place to escape to to do some relaxing pruning or whatever... sort of like a return to the womb thing. Weird, yes, but peaceful. The metal frame inside is green in color, but it's actually attractive and has done absolutely nothing to impair plant-growth. I honestly cannot think of anything negative to say about this tent. It is far better than a grow-room, as it is easy to clean and is air-tight so no bugs get in. Also you don't have to worry about painting the inside white or hanging reflective mylar. It's also very easy to keep clean- I can actually do some light mopping on the inside. And best of all, I can dismantle it easily and take it with me if I move. If anything non-optimal occurs regarding this grow tent, I will do a follow up post to let you know. However, I have a feeling it's going to be around for a long time. Thanks for reading this.

Muy completo, fácil de montar y de mantener. El forro de aluminio está perfectamente cosido al forro exterior y lo hace bastante robusto. Que se puedan sacar las vigas centrales es un puntazo porque si tienes que mover el foco o cambiar cualquier cable, no es necesario desmontarlo todo. Tiene varias ventanas y salidas con cierres ajustables. En general es un buen armario.

The 150X150 easily accommodates 4ea 12gal pots. I put it together by myself. Completely blocks all light from entering or escaping. Love the quality of the zippers. Plenty of access portals. Love the extra height you get. Just bought the 150X80X120 as a drying tent. I think the material is a bit lighter in weight. Both are solid purchases.

Set this up for a breeding project and it's been solid since day one. Assembly was easy, no bent poles or missing parts. Mylar lining and zips are holding up well with no complaints, and the observation window works smoothly. Genuinely impressed by the floor tray. My basement recently flooded and the tray kept everything inside dry even though the underside was soaked. It's not a guarantee against a proper flood, but it gave real extra protection when it mattered. Tent seems well enclosed too, no light leaks and no smell escaping. One small feature that's made a real difference day to day is the internal tool pocket, handy for quick access without digging around. Good for growers at any level, the build quality and small practical touches make it easy to recommend.

Hab mir das Zelt gekauft, Trotzdessen, dass ich paarmal gelesen habe, dass der Reißverschluss Licht durchlässig ist Und irgendwie auch der Reißverschluss anscheinend klemmt oder hakt. Hab es dann trotzdem gekauft, da es am Prime Day von 209 auf 159,99 € Reduziert war. Ich kann nur sagen ist ein top Zelt mit sehr hoher Qualität sehr wertig. Zusammenbau war in 35 Minuten erledigt und ich war alleine. Alles eingeräumt aufgebaut und steht jetzt seit vier Tagen. Glaub auf den Bildern kann man erkennen, dass nirgendswo Licht durchkommt und ich muss sagen die Folie innen ist sehr hochwertig und reflektiert sehr gut. Ein Highlight ist für mich das Fenster, in das man hinein schauen kann, ohne das ganze Zelt zu öffnen. Bin Soweit sehr zufrieden. Lieferung war auch perfekt. Sollte sich etwas ändern Folgen Updates✌🏼
