Humidity Dome??

Hey guys, just a quick question, if i put a clear dome over my pots do i need air holes in the clear plastic dome??
Cheers

It really depends, are they newly rooted clones or do they have roots and partying!!!?

they will be newly sprouted seeds

yes u need holes for seedlings not much tho

i dont use any just lift the dome for a few minutes a few times a day
