After reading three of your grows with the autopots, I have definitely downsized how big a system I want to get. I was going for the four pot XL system. Now I think I will only get the 2 pot XL system with the airdomes. My tent is a 90x120x178cm and after watching your grows I don't think I would ever have room for four XLs. In addition, it doesn't look like there is a big price jump to add additional pots to the system later on.
Thanks again for the very detailed grows. Very few people list out everything, including feeding schedules, in their journals.
