Awesome tent for the price. I changed my rating.
Update: I’ve been using this tent for over 2 years and it’s holding up great. I’ve also learned to resolve my earlier issue, with the roof. It’s not ideal but training my plants to grow shorter worked out better than expected. My last yield was over 4 lbs. I really can’t complain about the roof anymore. I’m changing my rating to 5 stars since the roof design wasn’t the hindrance I anticipated. The low stress training method resolved that. It also increased my yields more than I thought possible. I wish I’d tried low stress training with my earlier grows. I was always nervous about breaking a branch. This tent forced me to try a new technique and it worked out amazingly. Valuable lesson learn. Great investment, I’m glad I bought it 3 years ago. The price has increased dramatically. It’s still worth the value though. I’ll be buying another as soon as I can afford the new setup. A purchase I thought I’d regret turned out to be one of my best investments. If it didn’t have the sloped roof I’d give it 5 stars. I’ve been using it about a year and the quality is fine. The zipper does stick once in a while but I’ve had that problem on past tents and it’s an easy fix usually. My biggest complaint is the sloped roof. It restricts your light height to only 5 feet if that. That extra foot makes a huge difference sometimes. It would be great if the roof were square. I’m also using a 3x3 the same height with a conventional roof. It allows for use of the entire ceiling of the tent to hang my light. Overall all, if you’re not planning on growing tall plants it’s a good buy. Set up was easy and the zipper only came off once. Seems to hold a decent amount of weight and fits great in by basement which has 7 foot ceilings. I wish they’d redesign the roof to allow for full access of the tent height. I’d love to have another one with a standard roof. This was the only 4x8 that I could find with a 6 foot ceiling.

Dont hesitate buy one you will not regret. 2-in-1 Grow Tent, 108"x48"x80"
This review is for the 2-in-1 Grow Tent, 108"x48"x80". When the tent came in there was no damage at all to the box and the Amazon employee brought the package inside the front porch. Opened and counted all the pieces and everything was there. Maybe they are checking everything a lot better now to make sure everything is there. 5 stars for shipping and handling. Putting the frame together was easy no problems at all. Nice and sturdy even without the tent on, 5 stars for putting the frame together. Putting the tent was not the easiest thing to do even with two people putting the tent on. Make sure you have a enough room to put the tent on. I didn't and that is on me. Better directions and a video for this size of tent would of nice and much appreciated. 4 stars for putting the tent on. I did not need the second chamber as I have already have a seedling chamber. I will place a humidifier and a dehumidifier and a stand up carbon filter on the shelf. I attached 4 fans underneath the shelf to blow over the top and the bottom of the fabric pots for root pruning and to strengthen the stalks and branches. A co2 bucket will be on the bottom and the fans above it will blow the co2 right over the ladies. I like how the lights are attached to the bars and the can be moved left and right. I placed mine on rings so I can move them forward and backward as well to max the amount of light they can receive. I am using two 2000 watt leds, 3 gal fabric pots, happy frog potting soil, and advance nutrients for the veg and bloom. As you can see in the images that what eight days in the tent will do. I am going to enjoy taking care of and watching the ladies come to life in the weeks to come. Advance nutrients has a nutrient calculator that will advise you of the nutrients you will need and the amount. Start with half and work your way up to the full dosage. Better safe then sorry. Having nutrient burn is not a good thing. Any questions they have support you can call and ask questions. The temps are steady at 70 degrees and humidity between 60 and 70%. Do not over water. First knuckle deep in the soil if it is dry watering is needed. Over watering is bad so is under watering but it is easier to come back from then over watering as that can cause mold. You can get at least 28 3 gal pots in the tent. I opted for 20 as I like to be able to move them easily and not struggle with them. The sea of green method is the growing method I have chosen to use as it will produce a faster harvest and higher yield overall. I will update this review with more images as the grow progresses. I hope this review has helped you make the choice of wanting to start a garden and watch the garden grow and thrive. It can be a rewarding journey as you take care of the garden and watch and them grow and resolving anything that might grow wrong. No matter how long you been growing there is something you can learn along the way.

So Happy!
I'm getting ready for veggie planting season, but some plants are year-rounders. I typically keep them in random spots around the house, but when one of my big mothers (not pic'd) started to flower unexpectedly and unplanned, I had to figure out the lights and living situation fast. I have propped lights, but they've gotten unruly. I needed to hang them, but I'm not putting holes in my ceilings. I've been eying grow tents for a while and you can't beat the price and quality of these Vivosun tents. I bit the bullet and ordered Tuesday, and it with other stuff I got for it came Thursday, super quick. My husband brought the tent upstairs himself in a single, long, flat box, which surprised me - it was smaller than I expected. The two of us assembled it today in about an hour. One person can almost certainly put together themselves, but I imagine it would probably take about twice as long. It's just way easier with two people. All the pieces were labeled clearly, and they were all included as expected, which is half the battle. The quality is the other half, and I was NOT disappointed at all. The fabric is heavy-duty, but it's not heavy, in a good way. Some reviews had issues with zippers, and while there's almost always going to be a ramdom defect somewhere, our zippers had ZERO issues. There were one or two tough spots where you had to go over them a couple times to iron them out, but we didn't have any splits or bad teeth. They're actually pretty stellar. The rods are a thicker mL hollowed metal, not the cheap flimsy tin. All the pins popped into place with ease, even when we realized we'd positioned a couple corners wrong and had to redo them. No problems. The dimensions are exact with no awkward slacking. The instructions are a single piece of paper with a diagram, which leaves something to be desired, but honestly it makes sense and it works. Keep in mind, though, that you will have to figure out the most practical way to "wrap" the framing with the fabric. We put the tent in my small office, so we had to make do with a half and half approach, putting the left half into the unzipped fabric and then attaching the right half. There's more than one way to skin a cat, though, so look at how they suggest you put it together, but know that there are probably 4 other ways to assemble based on your space. So the first hour was the tent assembly and the rest was the fan, lights, wiring, plant placement and customizing, which took about 2 hours. Now I have properly hung lights and ventilation, and my girls and I truly could not be happier. My only complaint is now I don't get to see my girls whenever I walk past and smile, but I know they're happy, healthy, and it's for their own good. In a week when I do my veggie seeds, I know they're going to do awesome in this new space too!

Light Leaks O Plenty, Missing Part, Great Customer Service
Overall a nice tent, tight but easy to assemble, the directions aren't the clearest but common sense will take over once you begin to put it together...BUT its lacking in the light tight and zipper dept. It also says in the selling description that it comes with a tool bag, It does not with the 2x3 version. I sent viviosun a message to see if there was a solution and never received a reply. The tent is sturdy and the fabric is of high density material but like I stated already, there are light leaks all over it , to the point that I'm worried about growing photo period plants in it . the majority of the leaks are in the front above the top of the door and the whole zipper area in the main room, interestingly enough the clone/ mother room seems light tight.. Another issue pertaining to light leaks is the divider between the main/mother room, It is to big to fit securely . Normally this isnt an issue but the velcro location makes the divider have gaping holes around the top of the tent near the support bars.. They include a small roll of foil tape, I dont know if its them being thoughtful to the possibility of holes developing through use or if they know about the divider problem and are using this as a cheap solution. I really want to like this tent and use it because it's a solution to small space perpetual growing but I cannot recommend due to its issues.. The verdict.. I'd send it back for a refund but i'd never be able to get it back in the box UPDATE : The company has great customer service and we were able to come to a solution that was beneficial for us both, I'm under the impression that my tent was a minority and the majority of the ones produced are top tier. Thanks

Amazing product!
When it comes to things like this I’m a little bit skeptical about buying from amazon..after most things on here are from 3rd party sellers or manufacturers. When my tent arrived, which arrived two days early, it was fairly easy to set up. Anyone who is legitimately thinking about getting into the growing community is definitely smart enough to follow the instructions but I definitely think that they were a little bit difficult to follow. You almost really have to be a visual person to be able to follow the directions. The hardest part about getting it all together is putting the actual tent on the frame. The frame was easy for a single person but for the Mylar definitely get a second set of hands. The tent is just to big to do on your own as I’d imagine with any tent. I’m very excited for the size. Even with 2 chambers, I didn’t think it was gonna be as big as it is. You could easily 4 really good sized plants(we all know what this is really for..tomatoes). The tent comes with a Velcro wall that makes up the second section. The smaller side is really good for your veg cycles and the main side is good for your flower cycles. It’s amazing that you can run both cycles off of one tent. For me this is a major plus because I live with roommates and I need all the space I can get for my plants. It also comes with 2 sets of ropes for hanging your lights. Those came in handy because it gives you the ability to use 2 supports instead of the one that most grow lights come with. Not only was it easy to set up(for the most part), but I also now have a more secure, stable hanging mechanism for my lights and an extra set for the light that I’m supposed to get tomorrow in the mail. Overall great product. Also, I saw some reviews that said it wasn’t lightproof..that’s a load. Other than the ventilation/electricity ducts(which will be filled in when you get it set up) there’s absolutely no light penetration. 5 stars from me. Definitely gonna be buying some more vivosun products in the future.

This is one big ass tent, it's a room inside a room.
I've been using a 36"Wx48"Lx62"H for the past 4 years. I grew up to 4 plants in my old tent and just haven't been getting the yields I'm wanting, so I upgraded to this tent. It's a lil tricky putting it together so be careful, you don't want to rip it. You have to put the tent over the skeleton, once put together. Then lift the entire thing and pull the whole tent floor under the bottom of the skeleton and tuck it 6" up from the bottom around the bottom square. *HINT(Keep the tent doors zipped up, and have another person help so one person can be on the outside while your on the inside) However once I got it erected, I moved my 2-1200 and 1- 2000watt led grow lights, plus accessories, and 4 plants into the new tent. WOWW, I've have enough room to grow them up over 50" now and let em get really bushy. Honestly, I've now got 6 full grown marijuana plants that are producing an average yield of 7-10oz's/plant! I can grow 10 legally in my household so I bought a 3000wt led light for the smaller tent and now I can geminate/sprout/clone and start Veg stage in the smaller tent. Then move em to the big tent to finish Veg stage and finish to Flower and harvest. Now I have the room to rotate 10 plants consistently. This tent changed my game from good to great. It's so much easier to keep the hygrometer in the happy zone bcuz the design is perfectly made for ventilation. No more heat issues or over humid conditions, and I only use 2- 6" fans for ventilation 1 on each side of the top gable in the 6" ports for intake n outtake, plus the 3- 6" oscillating fans on the inside for air circulation. I highly recommend this tent for experienced growers, I'm constantly pumping out LB's/cycle all year round. I'm finally at the point in life, where I wish I've been the entire time and I'm only 40. What am I going to do with all this cured green 😁 I feel like I'm in Bong Appetite, lol. When I open my closet with all the flower I'm producing I can literally make anything that's made from marijuana. 👍👍 Good Buy!! I dig the Vivosun logos all over the tent material, they're like water marks on money or checks, you've got to look closely 🤩

Excellent Quality Tent!
First and foremost, this tent far exceeded my expectations. After reading the prior reviews, I was a little concerned about various aspects of the quality and assembly process, but it looked perfect for my spot so I got the 5 x 5. Once I got it, it went together very easily. The instructions were pretty crummy, but you'll realize pretty quickly you don't need them. I should note that my tent was only about 71" tall or so, not 72". This was actually perfect for me since I had a heat return vent to dodge. The cover went on much easier than expected, especially given the close quarters I had to work. It just slipped right on over the top and then I shimmied on the sides and bottom. Once assembled, it was pretty sturdy...definitely sturdy enough for my two LED lights. Unlike some reviewers, I haven't seen any quality issues with the zippers. They seem heavy duty and of decent quality. Also, my tent does't have any light leak at the seams (yet, at least). The seams on mine look pretty solid so I don't expect that to be an issue. Perhaps those with zipper and light leak issues got a lower quality run of these....mine has been great so far (2 weeks in). Very happy with it!

Perfect
What a tent should be. Added center height allows for taller plants. All kinds of vent holes...all close tightly. Floor pan is a nice touch. Easy assembly too. Overall great buy.
