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?

PH Testing
I have a vivosum ph meter, a ph tester for the up/down ph liquids and ph test strips. All of them don't seem to agree with each other with in a range of 1 ph across the ph scale. My question is what is the most reliable or is there a different method I should use?

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?

I was struggling with low humidity, now I can’t keep it below 70%.
Hi! Since upgrading my 4 girls into new 3 gallon pots & giving them a good water the humidity levels in the tent have soared to over 70% Will this reduce as they drink all the water in the pots? Shld I invest in a dehumidifier yet? Running out of space 😬

RH% and temperature
Hi guys, got the transplant done today as suggested by Burmese. I have an issue after transplant: - My RH doesn't seem to go below 62% - Is this level bad for the plant? - What is the optimum RH and Temp for this strain? - Or average optimum temp and RH in general? Thank you :)

When measuring RH within a grow tent where is best location hydrometer to record an accurate reading? I have 3 all calibrated together and placed at canopy, between light and canopy, and above light. There is a 20% difference between all three readings. I’m now in flower.

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?
