HELP WITH AIR CONDITIONER!

Half my mini split air conditioners went down yesterday and I'm 51 days into flower when my lights come on my room will be about 90°F. The repairman said the part may be here tomorrow or they may be here Monday. I thought up a few ideas/options of what I could do

Should I leave the lights off tonight and take the chance the parts come in tomorrow?

Should I turn the lights on and let the plants be in that amount of heat (lights will ramp themselves down to 300watts)?

Should I cut into my home central air and use that as cooling power (not sure if this will even work at all but is my only other on hand cooling solution)

If anyone has another idea I would really appreciate it

I'd run a duct off a ceiling vent directly to the space. Crank the central AC down until the dude shows up.

Only run half your lights

Cut lights down 50 percent and go on with your regular schedule. Plants can survive a little heat for a couple of days.

Mmmm. The argument for back-up equipment takes a big shot in the arm...

Portable's

Keeping the mini's clean - really fucking clean. Is something that my HAVAC guy says is mandatory! He grows and has one. He takes the covers off and cleans it monthly.

He says that's the only way to make them last.
He also says that Mitsubishi is the only one he would run for our purpose...
I can't back that statement......I run central and furnace in my building.....He put it in and wants to change to what I did.
