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...

serious question about VPD value in the tent I'm not sure which values I should consider more important, or both. I have one sensor about 10cm above the Canopy and one sensor directly below it. I am trying to keep the VPD optimal in this grow, but which one is the "right" one?

Hi everyone, I would like to ask you how you test Temperature and RH. Do you put your thermometer under the direct light at the base of the plants or inderectly, because I have pretty different values . If I put it under the light my temperature is near 35°C and RH is under 20%

What should be plugged into the digital timer?Currently, I have the timer plugged into the wall outlet, then to the powerstrip, but this doesn't seem feasible. I have lights, exhaust, fan, and humidifier connected to the powerstrip, so everything shuts off when the timer is off. Is this the norm?

pH Pen Calibration Frequency?How often should I re-calibrate my PH pen? I have a cheap Milwaukee pH600 and after 3 months of use it had drifted enough to cause real damage (was reading 5.8 when chemical drops read ~4.0). Alternatively, is there a reasonably priced option that would avoid this?

Can I use Smart Water to mix up ph powder calibration solutions?Cant find deionized water where I live to mix up my ph powder solutions and be confident they are correct. I used generic distilled water before but later realized it was not neutral at 7.0 ph. So long story short google says Smart Water is 6.98 ph, Think I can use it instead?
