Shit gemu, I hadn't got my first 600w until last month, I think it's all good
Gorilla tents are nice, but pricy. What I've been noticing recently when buying cheaper tents is the dimensions are smaller than usual. For example, I just got a 8x4 tent "quictent" brand. I wanted to put 4x4 tables in it but a 4x4od tray would not fi. So babasically it is like a 3.5'x7.5' tent and I'm disappointed because of that. That aside, it it built well and does not have many light leaks and plenty of vents. So if you want a 4x4 tent for a 1000w, get a 5x5 if going with a non name brand tent, because it will be closer to 4x4. Gorilla tents are oversized, so a 5x5 is more like 5.5'x5x5'.
Good luck, and nice sog grow by the way, looks great
