To cut or not to cut

Hey guys
I been told my girl has a few weeks left... at least.
I plan to be drying in my tent in the loft with a ac unit inside. Apparently we got a mini heatwave coming up in a few weeks (UK version of heatwave hahaha) expected near 20c+. My worry is, right now, 15c outside when sunny is 26c ish in the loft so if it gets to 20c it will exceed 30c in the loft. I will have a ac unit but I'm worried it won't cool down to 17c in the tent if the outside is 30c!
Based on this, do I cut her down now whilst the temps are manageable to try and achieve 60/60?

They look proper milky. Id cut

Well done
Be gentle

Thanks guys shes coming down

Shes down!!! The excitement is unreal!
Quick question, i have the extracter fan still on but on half power (350m3/h) and the ac unit in the tent with it on low. The tent walls are being sucked! Is it okay? I opened the vents but still sucking but not as bad. How do I fix this if the fix is needed?
Thanks
