Bests & Worsts Reviews from Amazon

I got it put together in less than a half hour, in a TIGHT SPACE! I have read some complaints about the zippers on these, and I had to laugh. One thing you need to be aware of just like with a sleeping bag is that there is an inner seal on the zippers that you don't want to get caught in the zipper, so it is good to pull outward slightly while zipping and unzipping. When they are new, it sometimes helps to stick a finger in front of the zipper to keep the inner seal away from the zipping track If I could have one wish at all it would be that the zippers had an inside pull tab (again, like a sleeping bag) so that they could be easily opened or closed from INSIDE... I now have a 4 foot by 8 foot to grow Buds in, and a 4 by 4 footer to grow plants that are younger and going through veggie stage on a totally different light cycle. The rectangular vents at the bottom of the tent have window screen material built into them, which keeps pet fur and bugs from getting in while drawing in cool air from floor level. This is a thing I like a ton! Not only the location and convenience, but that they are protected vents built in from the start Large 8 inch diameter ventilation duct holes with inner and outer sleeves and drawstrings are adaptable to any ventilation ducting you want to use, and are very secure. You can blow air out from any height, on the sides or even right out the top. There is a smaller 3 inch vent duct hole and collars that can be used for electrical cords or for a smaller vent fan such as is used to ventilate a bathroom/lavatory. And the metal frame is solid as a rock
