Drying in a tent with 45%-47% humidity and a temp for 20°c

Is this humidity too low for drying? I left them on the stems and am hang drying them in my small tent. It has a humidity of 45%-47% with Temps at 20°c. I don't have a fan going cause I'm worried the humidity will drop lower. Is it fine to have it at those temps and humidity without a fan going? Its about a week into drying but the humidity has only been that low for about 2 days. The stems are still bending and not snapping.

I would try and get it sitting in between 50/60 45 maybe a little to low

It should work.
I'd keep the tent sealed with a fan for air movement.
The moisture from the drying plants should help keep the rh in a manageable range.
