What’s vpd?
Vapor pressure deficit... not to worry you don't wanna go by that with co2 anyhow. Temls 80-84f and 50-55% RH should serve you well.What’s vpd?
Yes cooler and higher RH. It's the leaf tenls we worry about. 77-80 work well for me.With co2 though right? Without I should run the temps cooler?
Without co2 75-77f leaf temps.... this usually translates depending on lighting type used and how much IR it contains to about 80-82f.77-80 with co2 supplementation right? but if I’m not using co2 lower temps at like 70-75 are better? Also what ppms do you use when in veg?
The UV won't do much...its UVA but the IR can affect leaf temps... like I say way to many variables that affect leaf temls so of you wanna get an absolute then an IR temp gun is needed.I have 2 650 watt hortibloom leds with the uv & ir bars. So how far should it be from canopy? And I thought it was only good in flowering?
I venter to guess ph imbalance in root zoneyea they need to be transplanted maybe giving some light nutes
50-60% should be fine at that.I’m only using co2 at about 7 800 during veg... so should I still run humidity at 50%?
Make sure you select the closest spectrum.Yeah I’m on a iPhone but how do you even read flux, I can understand ppfd readings? Can you convert flux to ppfd?
Nope.Yo I have one more really dumb question if someone could pls help, I’ve tried looking this up but can’t find anything. So if I’m hand watering rock wool do I need to still add air stones to add o2 to the water?
