Os this good for drying?

warmer than you want and it'd preferably be closer to 60%, but you do what you can. AC is expensive, but adding some moisture is not. A humidifier might drop temp 1-2C, too. Depends on size of room and how much it runs. That's all an evaporative cooler is -- a humidifier without a hygrometer control. Get the humidifier type with a wick to avoid depositing a dusty residue on buds.

It might dry a little too quickly, try and lower the temp or raise humidity?

Nearly Perfect that mate I'd try and get humidity up to 60%

hey 👋 For the second week, I’d say yes; for the first one, if you can lower the temperature to around 20°C and raise the humidity to 60%, it’ll prevent a slightly superficial drying that might make you think it’s done when there’s still too much moisture inside. That said, with good 62% Boveda packs in the jars afterward, no problem managing it 😉

Yes

75f is too high and will cure buds to dry too fast. You certainly can dry faster if time.is of critical importance but it will be done at the expense of a noticeable drop in quality. Then again if your plant still has tons of nitrogen in nitrate form it doesn't really matter what you do as it never oxidizes during a dry. Regardless of what you do.
