Question about planting along windowsill

If my maxima x truncata, campanulata x lowii, clipeata x (clipeata x eymae) gorw quite well along the windowsill,
can I put the lowii x truncata, and EP truncata along the windowsill also?
Temperature around 25-30c day and night in summer (now)
They are now growing under fluorescent lights.


Thanks a lot  =)
