That the reason i waited to pop my gsc cross i just got my led a little 100x3w from mars hydro but its seem to do much better than a 250hps in my growtent (2x2)
Be careful, my tent collapsed out of nowhere and killed 6 almost fully grown plants. I hope you got the tent with the metal corners. This just happened to me so I will be spreading this message to anyone with a tent. I had two lights hung for like 2 years and I guess I should have thought to replace it but you don't expect the tent to just break down on ya.
Cheers for looking out. My entire tent frame is metal. With button lock corners
