VIVOSUNS448 4x4 Grow Tent, 48"x48"x80" High Reflective Mylar with Observation Window and Floor Tray for Hydroponics Indoor Plant for VS4000/VSF4300

I use this to house my 3d printer and it works great. Contains the heat and the fumes, which are filtered by a typical four inch charcoal filter used for adult indoor gardening tents.It was easy to put together, sturdy, and the zippers are good. Plenty of penetrations to run cables and vent hoses.Looks kinda crazy because it is so big but it is nice to have a room inside a room. It is a bit like a tardis, impressive interior with a desk, printer, some shelving, boxes of filament, web cam to keep an eye on spaghetti monsters, and pimped out with some led lights.The only thing missing is a dust cover for the top that could be taken off to clean. That would be much easier than a ladder and vacuum.

Nice and tight tent.. it has no saggy, good quality. Zipper feels like it is quality for the people who just love to go in and out a million times. Easy setup. Fast shipping. I would buy it again.

I recently purchased the VIVOSUN Grow Tent, and I couldn’t be happier with the quality and performance. Right out of the box, it was clear that this tent was built to last. The 600D Oxford fabric is thick and durable, with excellent light-blocking properties. Inside, the highly reflective Mylar lining does a fantastic job maximizing light efficiency, which has noticeably improved my plants’ growth.Assembly was straightforward and took about 15–20 minutes with no tools required. The metal frame and corner connectors provide solid support—no flimsy plastic here. Once set up, the tent is very stable, and the zippers are heavy-duty and smooth, which makes accessing my plants easy and hassle-free.The tent also includes handy features like viewing windows, a removable waterproof floor tray, and multiple vent ports for cables, fans, and ducts. These thoughtful details really make a difference for ventilation and monitoring without disrupting the environment.So far, my plants are thriving in this controlled environment. Temperature and humidity levels are much easier to manage, and the sealed design helps prevent pests and odors from escaping.If you’re serious about indoor growing—whether it’s vegetables, herbs, or something more advanced—I highly recommend the VIVOSUN grow tent. It’s a professional-grade setup at a very reasonable price point. I’d absolutely buy from VIVOSUN again.

This has been updated to reflect the company's response to my review: I have to say, Vivosun's customer service is excellent! They reached out to me within a day after I posted my reviews. After asking for some additional pictures, they offered me a a partial (over half) refund on the tent itself, and they offered to send me additional ducting to make the ventilation kit I had ordered more functional.The tent was very easy to set up by myself out of the box with the provided instructions. And while during assembly I had some doubts about its sturdiness, once assembled it has been very sturdy. I do have a couple design complaints, and while not as extreme as some other customers, I have some product quality issues that it would be nice if Vivosun customer service addressed and corrected in future production.In terms of design, Vivosun, please, ditch the windows with the velcro covers. The windows themselves aren't very useful (especially the one near the floor??), and the velcro on covers are not big enough to provide good light seals, they leak light around the edges. I'm going to end up having to cover those spots with mylar inside. Just make solid walls.In terms of quality...well... I had some similar complaints as others. Right out of the box and set up, there were pinhole leaks scattered around the tent walls. Probably a couple dozen. Quality control to ensure all outgoing materials don't have these shouldn't be a big deal. I'm going to have to do a lot of work with small bits of mylar tape to patch all these. Now onto the zipper...Out of the box, the zipper seemed shot. There were a bunch of places where though zipped the teeth on the two sides had separated, others where the teeth seemed bound up/zipped together improperly (skipping teeth, etc.). Thankfully, with some bow string wax and a lot of patience I was able to rehab it. But its not something I should've had to do with a brand new item. I figured that was the end of the zipper problems, until I had my vent system set up and a negative pressure environment going. With the outer walls sucked in slightly from the pressure, there were clearly light leaks about 2-3 in. long along the edges of the zipper in about 4 places. I thought it was from the stitching being pulled on by the pressure, but on closer inspection it wasn't the sort of pinhole leaks you'd get from that. Rather, it almost looked like the fabric surrounding and reinforcing the zipper strip itself was too thin or not properly overlapped and light was leaking through only partially opaque areas. Again, I had to spend a lot of time with mylar tape reparing this.Vivosun, please, fix these consistent design and quality control issues for future customers at the very least, even if you won't contact me to correct them.

This is a wonderful product. I bought a five foot long, three foot wide version to start garden vegetables and flowers seedlings. The frame poles easily "snap" together and although appearing flimsy during set up, are very sturdy and strong when finished assembling. The cover is very heavy and much thicker and stronger than I expected. The zipper is very heavy duty as well. There are a lot of viewing windows and ventilation ports. The cover was a little bit of a struggle to figure out and get on the frame by myself but was doable. Total assembly time was about 35 minutes by myself.I can 100% highly recommend this product as it has exceeded all of my expectations.
