So there's a bunch of companies that make cheap grow tents for under $170 on Amazon. Vivosun, Ipower, Growtent garden, LAgarden, Apollo Horticulture, Lighthouse.. Anyone have personal experiances with these brands? Most reviews for all of them seem ok. Most most complaints are weak zippers, cheap threads, and light lose through zipper.. Want to buy 2 5x5s.. Any recommendations?
