I like 24-26c for temps and 40-45% RH just like
@Papa_T
ideally cooler at night if possible.
Higher temps close to 30c can cause the plant to express itself in undesired ways. From foxtails to nanners and weird leaf growth, at least from my experience. also can help pests explode.
Higher humidity 50%+ can cause mold, lower humidity 30%- will dry things out to fast.
