Jax, Old PC fans make for good and quiet air movers inside the grow space. Assuming they are 12 volt you can use an old 12 volt phone charger to power them.
35% RH is not too bad for bloom but I am guessing that is with lights on; do you know what is with lights off?
A dome can work to raise the humidity for the seedlings just make sure that there is still some air flow around the seedlings otherwise they will have a weak stems
Hi oldster, I can raise the light by about 10 inches, do you think that will give the ww enough penetration in flower? That way perhaps it won't upset the baby boom. I will check humidity level before lights on in the morning.
Nice tip about the pc fans thanks.
Jax
Update the humidity was 38% at lights off.
