Ultimately, what is more important; humidity or airflow??

I know its a matter of distance vs watt.

I know he could be using a 1000 watt and place it further away, I would have thought a 250 would be overkill for a terrarium already so I am surprised.

I would personally not go for a 400 further away over a 250 but then maybe a 250 would be too hot too close

My setup does not include a light yet - 1 week test run completed - humidity does drop to under 60% when temps are highest.

I will be using a 10 watt IKEA grow light for 10 plants... and I have already tested it can burn my plants so is plenty strong enough at the right distance

I know I would not be spending 4 times what I spend keeping my bearded dragon alive on keeping my orchids happy.
