VIVOSUN Grow 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 poles are perfect for giving extra support to grow tents, but more importantly they stop negative pressure from pulling the sides of your tent in (important if using a carbon filter). I managed to set them up within 10 minutes; they clip on to existing tent poles easily and are pretty much perfect. I imagine they can also be used to attach a scrog net too; bonus!

Great bit of kit!!

these work very well and adds so much structure and sturdiness for using elastic trellis nets its a great option.the only reason im not giving 5 stars is that the price is way too high.

One small issue, they dont expand the tent as much as you may need. The old tent expander (expando) were alot deeper but kept braking due to the plastic connectors. So flawed.Please develop another deeper version like expando

Quality is brilliant. Unfortunately if you have a spider farmer 2x2 tent it is too short IT DOES NOT FIT I was lucky I had spare poles to cut down a little and used the pole hook attachments. Best part of the product is the hook connections they physically hold the walls out. 16mm pvc pipe will fit in the hook connections. I am keeping the kit for when I upgrade to a larger tent.
