BluelabMk2 Conductivity Truncheon

After a few unsuccessful hydroponic vegetable grows I took to the internet for a bit of research. I thought I was doing everything right as far as feeding my plants were concerned. How wrong was I. By using the exact directions on a liquid feed I was actually over feeding my plants. And how did I find out? Well by using this Bluelab Truncheon. The EC reading of my hydroponic reservoir was off scale. A month later I'm back on track with some healthy looking tomato plants.This Truncheon is a must buy in hydroponics to keep that EC in check. I'd be lost without it now.P.S. Dipping this truncheon in water from the tap did not work for me (unless you have dirty tap water). I actually thought the truncheon wasn't working. You do need a bit of feed in the water before any readings show.

Makes checking ec and ppm's a doddle. Expensive but worth the price. Imo let the truncheon dry before putting it back in its storage case to avoid mould etc. I just hang it up so it can drip dry

At last something that works. I use it for my pool, you pay for what you get. very satisfied and easy to read.

Well wrapped & protected, thanks, & love this quality product.
