I’m not currently using auto pilot but I have a lot of knowledge on the product. It’s not my preferred method of growing. For me it’s a lot of work. It’s a lot of water to mix and change. It’s a lot of work to keep your ph in line. Having a water chiller added to the mix is nice to have so you don’t get root rot but this adds more work keeping the chiller clean. Etc
But it works well and there isn’t anything wrong with the system. Just I feel there is easier and better ways. This is just my opinion I’m sure ours would disagree.
Just a FYI @FireGuy using this system now and loves it.
I’m not really sure I answered your question but if you have a direct question on the product I’m sure I can help.
Nothing looks wrong with your Grobo I think your on track.
You can look into adding some carbs (example bud candy) if you want but everything looks nice to me
