Is 85 degrees dangerous in flowering?

I have switched things around a bit in attempt to deal with heat better.
I took of my 8" exaust that was running 24/7 and am using that hole to outdoors as a passive intake.
I hooked up the filter and 8" vortex fan to now exaust into the house...
Any tips on active vs passive intake? I have a 12" fan outside I could use aswell...

85 isn't that bad honestly. depends on how often ur airflow is.. because ive had rooms at 80-85 with lots of air cirucloation coming in from outside.. and turned out great.. but had it with less airflow fresh air and it sucked.. n they stretched and was fluffy nug instead dense.

I could try constant intake and run at night if that's the case,I've done that before with decent results . This last run in there was fluff city,only difference was I ran during the day and swapped the intake to an exaust,but the air was warm by the time it got into the room..I will give it a go again but at night this time

ya man. switch to night for sure.. that's how we run the majority of our grows.. even if we flip flop.. we usually run at night as much as we can.. and then run as little AC as needed.. maybe a bigger extraction fan .

also switching to night .. u can just leave the lights off for an extra 12 hours. to switch the cycle.. if your plants are healthy not stressed.. it shouldn't cause any issues..

I agree 85 is not deadly, but its also not optimal either. I found 76-78 to be the best temps. just keep good airflow and make sure ti does not get any hotter. Also like someone else said night time light cycles will help reduce temps.

On my last co2 run I had temps of 85-87 and used promix,(had like zero roots) that run was horrible but I have wrote it off as learning .
This run was coco/perlite 5050 and I left the ac on 24/7 and no dehu untill last week or two and i used co2 however room was at 70-78 and did amazing .... I am truly impressed with coco. No sweetners carbs etc just canna coco and pk 13/14 I have never seen such crystal ly nuggetry .
Hopefully this next night schedule rocks ,
Bless and thanks for all your advice

It's not a death blow but really good quality weed (even with co2 is not grown above 80).

It causes a lot of stretch as well when you night time diff really starts climbing

More CO2 available lets plants survive better at higher temps. Also make sure you have enough air movement, and low enough humidity.... other than that, its high... but its at the edge of "still ok" for a peak temp....

Anyone else running into 80’s or higher trying to flower...

I’m thinking about flipping to get things rolling.. they are 7 weeks old and around 14-16 inches.. I’m worry about the heat... I’m running mostly sativa dominant strains and plan to run my 12/12 cycle at night.. 8-8 or 9-9..

This 315 in my 3x3 is a lil warmer than my blurples but at the same time plants are growing like crazy. I’m hoping the Sativas will like it...
