answered grow question 4y ago
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

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?

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?
