good idea to put the little ones in a white place like yours. i am also new at growing and i have similer problem with english plants look ok for me. good luck.
I putted them in that bucket to be more protected by weather,wind,rains etc -one of my plants had bad experience with wind.It broke the stem.I recovered the stem but lost the plant anyway it was male.
--he will be fine-- i hope she will be better, i read about the general tropical plants, it says they must take at least 5 hours DIRECT sunlight, so you can be more carefully abaut the shadow maybe
