This is a very heavy yielding plant, so when growing weed indoors, make sure to space them adequately or you'll soon be moving them out into the open air! In fact, Ken suggests you only grow outdoors and you'll soon see why. Bay Thunderboldt from GrandDaddy Genetics is a genetic masterpiece. Best grown outdoors, it produces big heavy buds packed with power. It takes the 12/12 photoperiod to begin flowering outdoors but when it does, watch out! In ten to eleven weeks you'll have massive nugs, covered in frost and the smoke is beyond powerful. You'll find a subtle hint of melon but with a major kick, so don't be fooled by sweetness. Suitable for increased appetite, pain relief, sleep / insomnia, stress relief.
