Humidity Dome

keep the air moving and you should be ok with the dome for another week.
keep RH lower.
S. Mtn. area and I only do auto's outdoors. everything else indoors.
too hot too dry and takes too long has been my experience.
a greenhouse would change that though

Apparently the OP was looking for advice that he had no intentions of following.
Good luck to you.

I ended up removing the dome and just placing them under a nice sun window. Just want to get them in the tent asap. I didn’t start them soon enough to get outdoor success in my area. Too hot.

I live in AZ. It will reach 115 in the next month or so. Will I have enough Veg time with SFV OG?
They’re all in seedling stage still in AC infinity dome kit. Should I just break down and buy an indoor tent because of my location?

They will veg until Aug 1st then trigger and show sex mid month. I'm southern California Latitude 33 and you should have much the same trigger date and flowering times. Harvest Halloween.

This morning Day 7 Seedlings. Do they seem like I can hold them in the dome so I can keep ‘em safe for another week or nah?

With some planning and a place 30 feet away to light up the veg stage plants you should be able to grow year-round if it doesn't freeze where you are. I get 4 harvests per year outside.
Aug 1st = Take clones
Oct 15th = Harvest, take clones, set out veg plants.
Jan 1st = Same
March 15th = Same
June 1st = Harvest, set out veg plants.

My buddy who lives in Joshua Tree can't run in summer so does the 3 off season sets.

Humidity Domes with a decent seal around the tray and proper hydration within the tray is going to be 90-100% humidity, really you only want that environment when your rooting cuttings, once they establish roots you should remove domes and start getting them used to fresh air.

I wouldn't overcomplicate it.
