## Questions & Answers

**Q: Does this pen really have to be calibrated?**
A: These are great pens for the hobbyist just remember when you do not see the check mark on your pH pen or on your PPM EC conductivity bluelab pen it is time to calibrate if you do not see this check mark displayed on either pin on the screen calibrate. I also recommend using the 7.0 bluelab calibration solution followed up by the 4.0 bluelab calibration solution to get a more accurate reading of the pH solution. Also use blue lab calibration solution for your conductivity meter as well these meters will last a very long time I had mine for almost 4 years and still in good shape keep your meters clean keep your pH bulb moist in store in the pH storage solution that is made by blue lab. Never let the bulb go dry if you do it will take 24 hours or it is good to give 24 hours to rehydrate your pH bulb. And if I'm not mistaken on the bottles the calibration solution of either your conductivity meter solution for calibration or your pH pen calibration solution it says on the bottle after opening don't use after three months I don't know if this matters a whole lot or not but I've used my solution over three months plenty of time and no noticeable difference in this. I guess the main thing is to keep your pH pen glass bulb hydrated I believe that this is probably the most important thing when owning a blue lab pH testing pin. If there is anyone to add to this conversation or to give me any advice that's positive please do so I am always willing to learn and listen so please if anyone has any experience with these pins other than me and something that I may not have mentioned or know please tell me or leave a review thank you I hope this has been helpful. And please stay positive with positive feedback just remember people there are no stupid questions and no mistakes only lessons thank you.

**Q: What is ec have to do with my indoor medical grown cannabis plant?**
A: The EC is an indirect measure of the fertilizer salts contained in the substrate, so those target levels will also vary at different growth stages. By starting an in-house nutrient monitoring program and measuring the EC, you can make sure that sufficient levels of fertilizer are available to the plants.

**Q: Mine wont read tap water, right out of the box. Is it defective?**
A: Sure

**Q: Description is contradictory - is this pen ec, ppm (500 & 700), ph and temperature? seller confirm please**
A: No ph
