27C is HOT! we rarely get that even in July ffs although i well remember being stripped to the waste in the loft covered in sweat and the temp in the flowering chamber being 32C. Hauling 15L of water a day up those ladders and it's all gone and plants bone dry and wilting the very next morning. Hated it bro, glad i'm not at that lark now. Hps is the past and more and more people are realizing the fact now. I know a few old growers and they are mostly stuck in their ways. Most of them have only seen a chinese blurple panel and were not impressed so they wrote it off. Time they had their eyes opened eh
Back to the light build for me now, making progress though.
