Is it true a male or female plants don't produce bud? If so, which one? What's the difference between male and female weed plants?~
I'm assuming you've smoked before haha.. Female will look like that. Male will look like a bunch of little balls that eventually open up and drop tons of pollen. You will know if you see them. Google a picture of male cannabis and female cannabis if you want pics.
They wont show sex though until flower so if you are using bagseed or non-femmed seeds you gotta wait it out although males from what I understand are usually lankier and grow differently, but it seems hard to spot unless youve got a bunch of experience and a keen eye.
