Sweetie, you just found out a secret- seeds don't really hurt your bud. (I've heard kids bewail their "ruined" buds, wondering if the pot would even get them high! LOL) Sinsemilla is nice stuff, but I was raised on seeded pot. There MAY be a slight loss of potency, but you'll never miss it. There is a higher than average chance of hermies from bag seed, but I wouldn't let that stop me from growing it! I can either cut the balls off or smoke him/her early as a preview of what's to come! Either way is OK. The only advantage of letting seeds develop is that you don't have to buy seeds ever again and, over the generations, you will have a strain that is uniquely yours. Sounds like you have a good start in your bag seed.
