Review: 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.
Review: 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 desertcart 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.

### ⭐⭐⭐⭐⭐ This size is perfect for the low ceilings in my basement!
*by K***B on February 3, 2026*

The tent material is thick and pretty good quality, it functions well in my basement which has low ceilings and can only fit a taller 4x4 in one spot of my basement. The flaps on the bottom of the tent help increase ventilation. This tent actually has less light leaks than my more expensive AC Infinity tent, for the size and price it was a super good deal. I just wish they would make it this size and height without the sloping "roof".
