hey there, your plants look nice and i hope you get females and a few pounds. and yes the person who posted about indicas not be good for pain is misinformed......the other poster who set the record straight about indicas and sativas is on point. i prefer indicas but there are so many hybrids to choose from.....for your disc pain and sleep issues try something nice like white widow, og kush, or something that is 70 indica and 30 sativa or 50 50,........try concentrates if you really need to be medicated......good luck....peace and pot
