VIVOSUN 48in x 48in x 80in Hydroponic Mylar Grow Tent with Observation Window and Floor Tray

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.

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.

a robust little tent, ideal for overwintering my chilli plants

I would give this tent 5 out of 5 but I'm unsure why it isn't 60cm deep. It is 50cm deep which is a bit narrow to grow my plants effectively. Having said that the 50cm width is basically OK and it does the job. Most grow tents are 60cm deep though and I feel this tent would greatly benefit from the extra 10cm. So yes this is annoying. In terms o0f the build quality it is better than most tents. I haven owned around 10 grow tents and this is among the best quality (in the top 2 or 3 out of the 10). It doesn't have light leaks around the zips like the majority of tents do and neither does it have heavy sips (often quite anxiety-inducing when opening in a busy home!). The build was way with high-quality poles and mylar fabric which has a strong reflective quality about it. The height of the tent is good and the vents, access holes and so on are well placed. Overall I'd much prefer if the tent was 60-62cm deep as I said but it is generally a very decent tent, looks great and feels like it will last for many grows. So, in conclusion good quality but an annoying size.
