Mango is supposed to grow massive and give off huge buds (up to 18" long and circumference of a woman's calf). However, I don't think it is a very potent strain, but not bad. The Big Book of Buds says it can yield 4-5 kilos per plant. If it's all for you then who cares if its not the most potent because you'll have enough to roll some huge doobies. That end result is probably pushing it though, unless you are experienced.
