i actually just finished a batch of blueberry(from clones)iv been offerd 6 blueberry seeds for £10 from a friend of a friend and i asked how he new they were female and his answer was " i dont no just all the ones i have done are female". Do u think i should buy them anyway as £10 is nothing and there could be a chance theres a female or 2 in there what do yous think?
