My gorilla negative pressure kit was the best thing I’ve bought. Worked great to keep the tent walls from closing in on my plants.
I actually Emailed AC Infinity and asked why they didn’t offer a negative pressure kit available for their tents and got a very subpar response… felt like I wasn’t taken very seriously.
I’ve now resorted to two options. Either using other tent poles and using rubber garden wite to tie them in or opted to use my filter and fan outside the tent to blow fresh air into the tent and turn it into a tent Balloon(reverse that negative pressure.)
