In party cups, FFOF 30% Perlite, all popped buried about a half inch deep and covered. Should I have plastic bags over the cups? The light close? And my main question how much water, if any, do they need right now? Its PH adjusted.
Throwing a plastic bag over it wouldnt hurt, they like a humid environment.. i would say just make sure the topsoil stays wet... should be enough for the little one to thrive off of, good luck man.
You shouldn't need to add any water for days. Too much humidity/water is a quick way to get stem/root rot. Moist, not wet. Wet
I just use my judgement man its the easiest way just look at ur plant with the plastic on it after a few hrs if its not dying and its standing proud it must like it but yes they do like humidity especially when there that little and if the soils wet leave it be it should be good for a few days especially with plastic over it
