Is mylar on floor needed?

[EP3]

Hi folks thanks for looking. Is mylar on floor important? Just i think a little more air flow through floor boards would be good. Temps starting to rise.
Thanks,

Not necessary at all no, you will be fine. What kind of setup are you working with?

Not needed at all but anything reflective can help a little. Even white paint for the ground or walls works well. Or mylar is a good choice too. Or a grow tent works awesome. They're very reflective
