2nd grow ammy

think this will be the last time I try and tuck any more stems under the net, tried a few yesterday but they have now become quite tough ro work with, so I want to avoid any accidents. Current temps in over here have been between 28 and 38 degrees. Tent has been hitting some high temps even with 4 fans on the water chiller has struggled to maintain 19 degrees and been hovering between 21 and 24 which is not ideal. To help with the situation ive been adding hydroguard in hope it will get me through the next couple of days. Before a fresh res change. I normally change my water every 2 weeks sometimes I have just topped up the res an again added hydroguard.
