Luckily I work at a metal fab shop so I got some 1.2mm pipe from work that fits well in the corner fittings. The braces were bending with noting but two 100w quantum boards hanging from it and it fucked with my OCD.
Didn't cost me any extra, so I basically got the greenfingers tents for the canvas. Surprisingly there is no pinholes though, and the stitching is good. The original cross braces are always handy as side braces to mount lights and tie points to lol.
I made the mistake everyone does at first....."I've seen plenty of dudes grow 4 plants in a 2x2 on YouTube with a 120w LED, I'll be fine"....a few months later, multiple tents and multiple lights later I wish I just picked up a 5x5 and 480w quantum board off the bat.
