I bought the 2ft by 4ft tent. It's able to hold quite a lot. I have grow lights strung across the top bar of the tent and on the sides along with a desk fan I bought for oscillation and to stress my plants. The tent sits on my porch where there's no heating but it is a few degrees warmer inside the tent than outside. May buy a heater later but my plants are looking greener and healthier than when I just had them sitting in the sun on the porch

Worth every cent! The only thing wrong is that one of the bars snapped but found something else to use that was more sturdy for the lights ect. Works very well in a small space!

Good tent for it's purpose. The zippers are always the give-away on these grow tents, and these seem to be designed to snag. There is a "lip" that is sewn into the design on the inside of the tent that unaccountably folds into the zipper no matter how slowly it's closed and causes a bind that is unbelievably hard to "unzip" and undo. Eventually it will bind permanently, leaving the tent useless. To avoid this end, I removed the zipper pull tab, forcing me to grip the zipper between thumb and forefinger and guide it closed and avoid the bind. But why should I? Don't they test their designs, or is this more built-in obsolescence brought to us by corporate short term profit strategy and greed? Remember the Chevy Vega?

She's a nice tent, was put up easily and moved into place within an hour. It can also withstand my 10lb cat standing and jumping off of it. Slay purchase 10/10

I'm generally of the opinion "Buy cheap, buy twice". However, this is my first grow tent and I didn't want to waste a lot of money learning which features are important to me. I've since bought other Vivosun products and they seem to try hard to be responsive to customer needs (smart!) and provide quality products at an attractive price points.

So...why buy a grow tent at all? For me, I bought an "Exhale 365" bag for CO2 augmentation, but had no way to keep the CO2 near the plants to do any good.

The most important thing I learned about grow tents is that the tent itself is just the beginning. I also needed a ventilation system, carbon filter, clip fans, ratchet hangers, ducting material, screw clamps, lights, power strips w/timer feature, fan speed regulator, zip ties, and a CO2/RH/Temp meter w/logging feature.

Another thing I learned is that most grow tents, are engineered to a particular configuration, but they don't tell you what that configuration is! It may be intuitively obvious to an experienced grower, but not to a NooB like me.

My "guess" is that the Vivosun grow tent is made for an inline HID lamp and filter, but that's not what I have. I have two (2) Viparspectra 450w LEDs lamps that I thought would provide ample coverage..hung lengthwise. However, I now believe that at 24x48x60 grow tent needs at least 1200w total to provide the most desirable coverage and canopy penetration. Otherwise, your plants may stretch into the lights. I bought a third Viparspectra 450w...with the idea of hanging them widthwise, but I will need to remount the carbon filter and vent hose to the center support to hang the lights the way I want.

This brings me to the fan. I bought a carbon filter, ducting, and a 4" fan from the hydro store. I used the Vivosun supplied straps to secure the carbon filter to the upper back left frame pole. I used a screw clamp to secure the ducting to the filter, zip tied the ducting to the upper back frame pole and ran it to the fan. The fan didn't line up with the 6" hole to the right, so I had to use a ratchet hanger to secure the fan to the frame and lower it so it aligned with the hole. I screw clamped another piece of ducting to the output of the fan which I ran out of the hole. The 4" fan is too strong for the 24x48x60 tent at full speed so I had to add a dimmer switch to throttle it back.

That's another thing...it would be nice if Vivosun offered a 24x48x72 tent so lights can be raised higher.

Additionally, this tent is not designed for clip fans...as the fat, plastic clips have nothing to clip to. I resolved this dilemma by removing the clips and suspending the fans with ratchet hangers (actually, an effective solution). I thought it would be nice to have squeeze clamps that fit just around the poles so the fans could be secured and moved simply by squeezing the clamp and sliding the fans up or down.

The tent if fairly easy to set up. However, the instructions are quite terse. You really need more room to assemble the tent than a 24x48x60 inch space. Once the frame is assembled, you have to open the tent up, attach the top of then canvas to the top of the frame, then roll the tent to its side then upside-down to "roll" the tent over the frame. Zip it up and turn it right-side up...and you're done! The instructions don't describe this process well. You're pretty much on your own.

This tent has many "options" designed around a HID lamp solution. However, if you're using LEDs and using the tent to capture CO2, it doesn't make much sense to have floor vents...as CO2 is heavier than oxygen and nitrogen and would leak out.

The floor vents don't seem to make much sense for photosensitive species that need periods of complete darkness to flower. My tent doesn't have any stitching issues described in other reviews. I really like the high quality zippers and the overlapping flaps to keep light out. However, the stitching around the velcro of the vent flaps and the window feature can let some light in. I duct taped them all shut and have a very dark tent.

That's the next thing...the window. What a hokey feature! The plastic is hard to look through and at a level for a child or someone in a wheelchair...not someone 6'2". My zippers meet at the upper left-hand corner. If I want to observe my plants, I unzip along the top and peer in when the lights are on. If you need to look at your plants during sleep time, and have a green light in your room, fine...but why not just unzip the top and get an unobstructed view. All the window does is let in light around the seams, so I duct taped it shut.

I'm not saying the window isn't a nice feature for some, but I shouldn't be forced to buy the "handicapped" model if it doesn't meet my needs. Btw, if you can't go 12 hours without looking at your plants, perhaps you should forego the grow tent and spend your money on a psychiatrist, instead.

The zippers are nice, but they don't flow all that smoothly with the light flaps on the inside of the tent. I find that if I run my fingers inside (to push the light flaps away) as I zip, the zippers flow much more smoothly. Of course, this requires two hands to zip it up.

I really like the velcro strap to hold the door out of the way when unzipped. However, it would be nice if there were a second velcro strap on the inside of the tent to hold it in place as I try to zip it back up. As I mentioned, it helps to run your hand ahead of the zipper to keep the light flap out of the way, but you can't do that when you're like the little Dutch boy with his finger in the dyke...holding the door up top with one hand as you zip with the other from the bottom...and the zipper getting constantly stuck on the light flap.

With all that said, here's my review...

Pros:
1. Easy to assemble (once you know how to assemble it).
2. Sturdy and well constructed.
3. Vents close up tight. The tent sucks in about 2" all the way around from negative air pressure.
4. No light pollution once vents and window are duct-tapped shut.
5. The drip pan is a nice feature!

Cons
1. Terse instructions
2. No discussion of necessary additional equipment or how the tent is designed for that additional equipment.
3. Short (a 72" model would be nice!)
4. No windowless option
5. No strap to hold the door in place while zipping up.
