I use the autopots and MC2. I find I have had too much "swing" with the PH. So I mix the nutes in my big bucket and let it sit for 24 hours and the adjust the PH. This seems to have stopped the huge swings. Glad your on board with the AP. Yes, they give you freedom Not to be home everyday. And your garden still grows. This is why I went with them. As always read, read and read. Some one is always home or awake. Do you have a grow journal we could follow along?
