Where can I buy my pH equipment. I need a meter and some adjusters. I have seen some soil adjusters at home depot unfortunately I haven't been able to locate a meter. Any help would be great thanks

The hydro store.

the dro store or online is ya best best.

any garden shop should have ph testers.

Plant Grow Lights, Indoor Hydroponic Systems, Supplies/Equipment - Best Prices, Products & Delivery AHL Garden Supply i have a control wizard pen, it's great instant read, but they make probes you can drop straight into your reservoir.
