Is 55% RH to low for seedlings? I have a new seedling in the tent with my other ladies and I'm wondering will she be ok.. she is Lambs bread which is pure sativa ( if that matters )
Its fine, I like to seedlings aorund 65-70 but that's a bit high. anything between 40-60 is perfect.
You can reference a VPD chat for temp/RH charts that say what the best options are.
