Will these work for a pH meter?

  1. I'm starting my grow very soon, I'm growing in coco coir and using Hesi coco nutrients, I don't really want to buy a digital pH meter as they are too expensive and a bit of a hassle. But I've found these on ebay 100 Strips, Alkaline pH Test Strips Kit 4.5-9.0 Saliva & Urine | eBay

    Will they do the job? they can measure 5.75 which is pretty close to 5.8 which I've been told is the best pH for coco. Any advice would be appreciated!
  2. i wouldn't see why not... should be cheap, give it a try
