yeah, its not even worth while trying to gather a bunch of pins.
Im thinking it would take somwhere around a 100 small aborts to trip.
maybe less for some people. Your cake doesn't look to bad for the first flush. A couple of those look like aborts though.
As for the strains on sporelab, They have the best strains around right now, I have ordered from them numerous times and im always happy and satisfied with the potency. Really, The potency doesn't vary much from each strain. It may have somthing to do with how they are grown, but every cubenses has about the same potency. Equador, Pesa, Dixieland, and costa ricans, are supposed to be really potent if you are having a hard time picking out some strains. B+ is potent as well.
The guy who owns the place is also a really nice guy. He always answers my questions promptly.
goodluck buddy !
