Bay Thunderbolt is a massive superstar of an outdoor marijuana strain that is the result of crossing a Humboldt Honeydew with a Bay 11. Its heavy, dank, sweet ‘n' sour aroma and flavour will have you craving more of its dense and sticky buds. It takes between 10 and 11 weeks to finish flowering but the wait is more than worthwhile for enormous yields of incredibly potent weed. Anyone looking for huge outdoor plants need to look no further.
