Dosing pumps for fertilizer
So I am wondering if any of you have any experience with dosing pumps for the PPS-Pro fertilizers? I am out of town a lot and I am considering purchasing one to ensue to my plants get their ferts an hour before my lights come on. I would like to keep the cost under $100 as I have seen some of the saltwater setups run pretty high.
