What temp would you suggest for a LED setup say like a Mars hydro or a Spiderfarmer? And why?

I seen and read the same. Tho in there I also seen that above 85F Co2 should be used. Then you can tread into the 90's.All info I have read, come across, and been informed here has been mid 80s with 86 degrees / 30 Celsius is the target.
LED lack the IR light to warm the canopy to proper levels. Without the higher temps the plants can't transpire. This is during veg.
During flower I was informed 82 is the target.
27 to 28c is the target day temp. 20c is fine at night. Lower temps for last 2 weeks to 21 to 23cWhat temp would you suggest for a LED setup say like a Mars hydro or a Spiderfarmer? And why?

Another thing I don't like to do is swing my temp everyday by more than 10F between day & night. I run 70F at night, so I try to stay just under 80F.All info I have read, come across, and been informed here has been mid 80s with 86 degrees / 30 Celsius is the target.

Same with VPD. 86 degrees and 75% rh. It never gets higher than 86 and never lower than 82.I seen and read the same. Tho in there I also seen that above 85F Co2 should be used. Then you can tread into the 90's.
I try to stay in good vpd.
My experience with indoor setups is limited as we all know.I can't settle this, as I don't know what the temp in my space is. I can say that I don't heat it, so the temp with the light off is 22C, same as the house. The light would warm it up some as it is enclosed. It's also the same humidity as the house which is about 35%. We have a dehumidifier in the basement that is set to 40% and hasn't turned on in two months.
The spiderfarmer lights are supposed to have IR diodes, so I don't know if you would have to raise the temp.
I guess I'll find out.
As I've said before, people sometimes yell at me saying what I'm doing will never work, and my plants will die. I just smile and say "okay". I pay attention to what they say, and if they seem to be right I put it into practice, but what is necessary for me or you might be optional for someone else.
I did homework for a couple weeks when deciding to switch to LED. I spoke to other growers I know, a few people seemed to think the Mars Hydro was a good product for the money. There’s a three year warranty... honestly, I knew it was stepping out of my element, but not in a sink-or-swim way. So far, the Mars is growing my plants faster with tighter node spacing / structure than cfl, MH and certainly HPS. Internodal growth is incredible for how young the plants are. I’m going to post my grow when it’s a little further along. If flowering goes as well as vegging has gone so far, this is going to be a good light.What temp would you suggest for a LED setup say like a Mars hydro or a Spiderfarmer? And why?

This is my first LED grow, so I'm expecting to make mistakes. But I've seen a lot of "solid facts" fall by the wayside. I'm not saying you're wrong, just that what works for some other growers utterly failed for me and vice versa, and while some was probably grower error the first time, after a couple of tries you sometimes just have to accept that it won't work for you. I don't know what will turn out to be right in this case, and personal experiences will differ for a variety of reasons.My experience with indoor setups is limited as we all know.
But what I can tell you is that at the beginning I didn't believe it needed to be that warm and that humid.
Until I tried it and saw explosive growth and new growth issues dissappear.
I thought it was light intensity. But upon further review of info out there and what happens if its not dialed I found the lack of heat and humidity was causing new growth to come in shriveled.
Maybe it was a combo of light intensity and VPD needs. But the temp and humidity shift made a ton of difference.
I'm with ya on the what is apparently etched in stone is absolutely no where close to etched in anything lol.This is my first LED grow, so I'm expecting to make mistakes.

I will say that this isn't the first time I've grown outside of what others consider optimal temps and humidity. But I have also grown within them. Any differences affected my personal grow style to some extent. I think there is a range of conditions this plant can grow within, and that to some extent it adapts to its environment. I also think that range becomes narrower the further we get from landraces, but that's a subject for a different thread.
