Is she looking healthy? Day 4 after being planted....

plants take in moisture through roots and release water through their leaves and not vice versa unless we’re talking about cuts waiting to root. the reason you keep a higher rh in veg state is not so that plant takes up moisture from the air mostly but at low rh stomatas close or severely shrink in order to conserve and regulate water content inside the leaves which in turn slows down growth because the way plant takes up nutrient and water is through pressure basically. as it releases water through stomatas it pulls water into the leaves and that water is pulled by the roots from the medium. so more water it releases through its leaves more nutrients and water are taken in by the roots. but as stomata closes in extremely low rh this process slows down. anything over 40% is managable though and 55-60% is good in seedling and veg. and again i wouldnt wrap a seedling with wet towel just water your plants and gice it support because that little gal will fall over in a slight wind.
