5 times a day at 15 minute drip times is what I use to do with good results. Depends on how much water comes out of your drippers. There are ways to figure it out. Sure if you look online you will find the calculation

RH% and temperatureHi 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 :)5y ago

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?Week 12

Set auto system for VPD or RHI 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?3y ago

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?Week 7
