Clones in high temp, high humidity

I just took some clones and am hoping for some advice. The temps here today are stinking hot 38c 100f, and sticky humidity.
I have the clones in an area with a nice breeze and the temps there are about 33c. and I have the dome lifted fractionally.

Should I lift the dome and allow good air flow, or should I hammer the humidity to combat the heat? Or should I try and lower the temp and bring into some ac?
And should I mist the leaves straight away?

Cheers for any advice :)
 
It all depends on your clone setup and how you are doing them , im in the same temps as you and i use a bubbler with a dome, bubbler is set to spray 24/7 for the first 4 hrs and i have the dome shut and i give them a misting a couple of hours apart until they settle in after 4hrs the spray interval is set to 6 sec on every 3min to encourage root growth .
The next few days i partially open the vents on the dome .
Have you got any pics of your setup it will make it easier for people to give advice with as much info as possible .

I will grab some pics in a minute. It's basically a cheap dome/propagation tray with rock cubes.
I wasn't planning on doing any clones, but it looks like all the regs are ladies so I won't get any pollen to chuck. One plant is loving the conditions so much I thought I have to try and preserve the genetics in case it turns out to be a cracking smoke. So I just went to bunnings and grabbed what I could.
 
Yes, that's the one. I think I made the clones a node too long.
I will set up my tent and move them in I think, can always grab a couple more tonight.

Just don't want to lose this girl and she's a late starter and may not see the best finish.
And no seeds from 5 regs but could have been all boys which would have really sucked I guess.

Yea thats the tray ,they look happy no signs of stress so far
This is the top of the mother, she was a late starter with a couple of others, but has got crazy huge suddenly with the stretch. and is four times the size of the others.
She has a real Xmas tree style structure. And is eating up the sun like nothing else I've grown.

Bit hard to tell from picture on phone but it looks female ,some plants are vigorous especially males . Hopefully it yields well for you .
Here are my outdoor ones

That looks really cool, I will enjoy looking through the thread.

The one I got in early is looking nice, hard to get decent pics, but it's one plant tied down. She should finish before any worry about frost. The one I'm cloning is showing girl bits all over it so pretty sure I'm looking good there, but may face a problem with cold temps before she is done. It's just everything is over size on her, so I'm dreaming of a chunky cola

By no means a full blown tree like I see some of you guys grow, but she's just a baby that has thrived for some reason.
The top gives good perspective to the side pic.

The nodes dont look to be staggering yet so shes still in veg and has a bit to go
Yeah, I think that's why I'm so excited about her. It is a really young plant still, but has some big genes that I would love to see in a full outdoor season. But the temps are going to drop in a month or so.
I can use a trolly and keep her protected for a while longer, but my best bet will be to clone her indoors until next season.

I have a super skunk thats 4ft tall and still in veg it will be interesting it should only be an issue if our plants get big dense buds otherwise a bit of cold wont be too bad they will just start turning purple so long as theres air flow it should be good

I'm not sure what strains mine are, but they came from a good source who is lucky enough to get the good stuff for his breeding.

With more heat you want some more humidity.
Bit upper range probably with the 33c, but enough humidity and not too much light
and the roots might appear pretty fast.

That's a handy chart.
Late afternoon yesterday one clone suddenly drooped, so I brought them inside and after about ten minutes it had stood up again. All looking great with them this morning. Fingers crossed.

What timer are you using to control your pump?
