I personally think that anything below 60% is too low, unless we are talking Cubans. But that's a matter of preference. As for temp, it really doesn't matter as long as you keep the temp lower than 75. Yes, beetles can hatch at temps as low as 65, but you usually run into problem when temps go over 65.
