Afghan Auto Flower - Auto Pot

So far, this week as been really good for me to learn Autopots. Learn in the sense that you don't need to do as much LOL. This is my first use of the Autopot system, so it was more about me becoming confident that it was in fact working. When i put my finger into the coco coir like I would with soil, its perfectly moist. The other thing I have learn't is, 1 ml of nitric acid PH's down .1 in my res. Given its size, it makes the math very easy to maintain. It had gotten up to 7.2PH! I put in 10ML of PH down, and it settled right back to 6.2. The one issue that I have also seen happen, is the res temperature has raised the same ambient temperature of the tent. I am hoping, that in these case the Soil will act as a buffer against that temperature. Otherwise, I worry like a DWC it might develop some kind of root rot. If you have used Autopot's before and have experience in this topic, please let me know :) Thank you
