as you can see from the photo one was popped sooner then the other i went and check on them the next day and noticed the other one and was like WTF i didn't know this could happen
did a bit of reading and most people say let it grow and kill off the small but i was like wtf ill transplant this mofo seeds are not cheap and didn't think it would hurt much and it didn't

if your plant is a bit far along it wouldn't try it as the root system might be all tied up i got in fast and they were both only at tap root stage! so didn't stunt them really and both were the best out of the 9 plants
