you welcome and yea is looking like the leave is obsorbing the water more faster now.
give the mist dome about twice a day for 10 minute at a time is about perfect.
However if you planing to make your seedling grow at a fast rate give it intense light for 24 how and let the leave draw out some more. in this case if it does dry out faster, more often than apply 1 more dome time daily would be better.
remember the more dray out time that your little seedling get. the more often you can dome it your seedling will uptake faster and become stronger to the enviroment and will want to take up more light more easily and also it'll grow faster and begin to produce big top shot for further plant develpment.
your seedling is look really heathy now and well on there way of big growth soon.
pretty soon it can take up all the light you want to give it and grow the way you want.
also keep in mind later on seedling stage is that, the terminal stem is determine on the size of your fan leave the bigger your fan leave is it will connect from the fan leave bottem stick pencil looking part to your teminal stem, which interm will create a bigger size plant that grow bigger faster. (considering the littlle small bottom growth shoot is possible could help over all determine the bigger growth size of your plant in the long run. but really see the virgerious of those shoot, to really see if is worth growing and to see if it will grow out into a bigger part for you plant, if is not worth keeping in th end than even if it makes your plant stem and shoot a little bigger some how. is still better off not grow those few little shoot.
