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?

Are these photos good enough?
Should I invest in a stronger lense clip for my cell phone or are these photos clear enough to judge harvest time?

RH 90% during Flowering!
I have a problem with RH. I am at the 3rd week of Flowering and I'm struggling to keep my RH down. Today it was 90% when I opened the grow box. I have access only to a window. Is it better to suck air inside or blow the exhausted air out? I can't do both

Inkbird
I bought a inkbird itc 308s to control temperature. In heat plug I put a little heater, but in cold? I was thinking to connect extractor, but until now in my grow the extractor was always on, from 1st day of veg to last day. So, should I connect something to cold plug or not?

Hey growers, I'm new to the indoor world, and I'm having trouble learning about ventilation and air extraction. I have a box that's 90 x 90 x 180 with an extractor Ø 12.5CM - FLOW RATE 280 M3/H. I also have a humidifier. How should I set the timers to save energy as well? Thanks!

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?

False reading or Hi PH?
Is 20% humus lombrico mixed in my substrate giving a false ‘hi’ ph reading? Or is it truly over the max reading? I got one reading of 7 only at the exact second I took the picture, so I made a video. My water is high in calcium, I recently switched to distilled.

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%
