VIVOSUNGrow Tent High CFM Kit, Green Pole Range of 24"-48", Suitable for 2'x2', 3'x3', 4'x2' and 4'x4'Grow Tent, 4-Pack

These fit and work well on a 3'x3' tent. Definitely keeps the sides from collapsing in due to ventilation fan. Snapped on my poles without issue. Did not change noise level. Gives you back the full space of the tent. Does stretch the material a bit and lets a little light out around the zipper stitches.

I really like this product. Creates so much more room in my tent. Keeps the plants happy! Worth the price! Easy to assemble. Great invention!

Works perfect with spider farmer 3x3Keeps sides from sucking in

These fit My AC Infinity 3X3 the clips are a little hard to fit on the slightly larger poles of the AC Infinity grow tent. I suggest fitting the clips without the poles attached first just to help loosen up the clips. All in all I'm happy with this Hi CFM kit from Vevosun not bad for the price

These are awesome and so easy to put together. They function perfectly for what I need and they are the perfect size since I can adjust from 3x3 to 4x4. But there is NO WAY it would fit anything under 3x3 tent.

Good quality. Ease of assembly. Make sure it's for your tent. I was bummed it didn't fit mine.

Build quality is surprisingly sturdy; much more so than those I've bought on Etsy. The ends click on securely and are just barely slidable on my tent poles. That lets me slide it up and down depending on where the plants are widest at their current growth stage.What's really nice is how they angle outward vs. just straight across. This takes up even more of the tent slack. That may make it a little more challenging on a brand new short measured tent, but should get easier as the tent is used. My tent isn't new, but it has always been a tight fit around the poles. I only struggled to get one of the ends on a tent pole. If you can get your finger between the pole and the tent, you shouldn't have issues getting this on.Hint: Attach all of the plastic end pieces before adding the bars. Had I done that, I wouldn't have struggled at all.The only real drawback I've come across is the size of the pushbutton holes for the bars is a bit smaller than my fingers. Since it's usually set-and-forget, it's not an issue for any but the front bar (so you can get in the tent). Because I have big fingers, I cannot easily push the metal pin in far enough. What I will do is remove the pins for the front one to avoid the issue. The tension bar adjustment will keep it together.Really, really pleased with this one.

Don’t use with a 6in inline fan on full power. The black plastic pieces will be the first to give out. Im very disappointed it lasted 1 month before all black plastic pieces completely bent inwardson all 4 corners. If you use an inline fan on high be weary. My tent with high cfm kit and a 4” inline fan on high is fine but the tent with the 6” inline fan the pole buckled. So frustrating. Makes me wish i bought all ac infinity for quality product.
