Nah man absolutely not. You would think the same thing with grapefruit being a canuk strain, but it is bud rot hell. Even if shit is in check at 45 humidity. Everyone may remember a very famous old school strain Sweet Tooth. Fuckin awesome, but same bud rot problem from the grapefruit like everything it is in. It is 100% hereditary, but don't let that turn you away from tryin it sort of like hermies and GSC/Cherry Pie/SD. Just keep humidity way down and don't run it outdoors period. Cali-o for the record will do the same thing, but not quite as bad. Positives from grapefruit are amazing terps, medium hvy yields, quick harvests (48-53 days), and great grow profile (don't top it even in crosses). I am buying a zkittlez cross right now /shrug just wont run it outside.
