Do you water to runoff?
explain your setup.
Lighting - make model and wattage?
Extraction system - make model and CFM/M3H?
Temps - high and low?
RH - high and low?
Nutrients - brand and strength being used
Soil/soiless/hydro - organic/coco/DWC/recirculating etc?
There’s one thing that must be right before you proceed.
thats your ability to control your environment.
The biggest things that I say to people
Perfect your environment and learn how to use your choice of nutrients and bountiful harvests will follow.
If you don’t try to perfect your environment and you have no idea about how to use your nutrients then you will fail each and every time.
That’s a kPa of 1.3 and kinda high for veg. Not to mention pretty chillyOne thing is for sure, you do not want cold with high humidity and you do not want hot with stale air, both of these conditions is opening the possibilities for pests, mold and diseases.. You want a comfortable temp which is around the 75 degree mark with an even amount of RH in veg, say shoot for that 55% mark and then in flower if you can bring it down to 50% that would be great, if you cant then I have ran 55% RH all the way through with no problems... You can adjust the RH by a dehumidifier to bring it down or you can even moisten towels to bring up the RH if you needed.. There are ways to manipulate your environment without spending tons of money.
Whelp, kind of yes. Especially if you're running LEDs where most likely your LST is a few degrees below your ambient grow temperature. Lots of us are in the mid 80's in our tents. My 'lights off' temps are 77-82.75 is not chilly at all.. You must be tropical based, up here it gets -40.. 75 degrees for an indoor veg room is not chilly at all.
I’m not pointing at you as a know it all. Just saying don’t be afraid of humidity during veg.I never claimed my way is the best way, each person is different and that is why I said they should research the best for their growing style.. With me, 75 degrees with 50-55% rh works great, and this setting has worked well for others that I know.. As far as organics, this too has been proven to work and it is also a personal choice as to which style someone wants to grow, I do not like hydro, I tried it when I was in my 20s and it was a nightmare, I switched very quickly from that to a soil base type grow, since then I haven't looked back.
im standing at 84 in all 3 right now. Lights off temps no less than 76Whelp, kind of yes. Especially if you're running LEDs where most likely your LST is a few degrees below your ambient grow temperature. Lots of us are in the mid 80's in our tents. My 'lights off' temps are 77-82.
My veg VPD is 1.3ish average, very occasionally dropping down to .9 but mostly in the 1.1-1.5 in veg. Once I get into flower and things start bulking up, I'll drop my humidity where it sits now 59%-63% to something in the 50-55% I've done this previously and found it worked well without any issues with PM, etc.But have you tried working with the vpd? To even have a comparison? Makes a big difference. Just because it works for you. Doesn’t mean that’s the best way. Trust me. I learned that with coco and irrigation. Cannabis plants have a chart that’s widely available online that makes it a breeze. As long as you know your surface temps. It’s help with accuracy.

Same, I never really put any thought into it, my RH has been in the same area for the whole time., it fluctuates slightly when winter gets here but its not enough in that room to even be concerned with..75 degrees (24 C) 50/55% is green zone on Pulse's charts for veg.
I didn't worry about any of this junk for years. I had a stick thermometer I never looked at and didn't worry about humidity at all if it was fine for me it was for them. Plants grew just fine. This ac infinity stuff gives me loads of info and it definitely helps.
I am 84.2 with lights on.
1.3 kPa is noted for mid to late flower. And considered high. So yes. It’s the sweet spot for harvest time. But like you said it yourself.75 degrees (24 C) 50/55% is green zone on Pulse's charts for veg.
