Hola, lo mejor para estas mediciones son las marcas BlueLab y Apera Instruments , son un poco costosos, pero es lo mejor, si quieres algo economico puedes optar por un 4en1 como Vivosun (economico , bueno y confiable)

Hi there! I recommend on investing in good pH meter and couple cheap Ec meters in case otherone brokes. Ec (Electric conductivity) is measured by two metal pins and it is really cheap and easy tester to produce and the cheap ones as AS GOOD AS the expensive ones and they have calibration option too. I have this one https://img.staticbg.com/images/upload/2014/08/SKU159586/1.jpg and even tho it does not say it there is calibration screw under that gray tape thing. pH is measured by hydrogen ion activity in the water and accurate testers are more expensive to produce and the good ones has better calibration options etc. Ec meter wont brake that easily and it holds calibration pretty good but pH meter MUST be stored in KCL or other storage solution and you must take good care of it so it will last long. I have already broken two pH meters with bad maintaining...

Set auto system for VPD or RH I have AC Infinity set up. I am wondering whether I should have the humidity triggers set up for VPD or continue with RH triggers. So far I have it triggered when humidity gets a tad low. If I trigger for VPD, I think I will have to constantly check leaf temp. Thoughts?

Hey...Grow Diaries...What is going on?What is up with this web site. Shuts down Friday and starts up on Monday. Is someone having a long weekend every weekend? Has this site been hacked? Should I be concerned because you have some personal info of mine? Can you tell us what's going on so we are not so concerned?

Cord for Vivosun Controller to automate an electric heater I have a Vivosun CFM In-line duct with the Temp/Humidity controller. We’d like to connect an electric heater so that it can automatically come on when the temp is low inside the Tent. Any suggestions to what would be compatible to my Vivosun temp/Hum Controller?

Reducing PPM without changing water in hydro Thanks all for guidance on my previous question. As a follow up, can PPM be lowered by reducing feeding until they hit the right range? Currently 1500ppm but seems this is too high. Currently following the AdvancedNutrients plan.
