Okk ok, i heard differntly but i guess it makes sense..
Wait you forgot to finish the following paragraph...
Male Marijuana plants do in fact grow THC. The Male flowers contain THC, but a much smaller amount than the Female flowers. Male plants also produce THC on their leaves, but again, it is a much lower content than from Female leaves.
Male plants are rarely harvested as the flowers have a low THC content. Female plants can have as much as 20% THC content on the flowers, while Male may only grow as much as 3% THC content on the flowers. From personal experience, I have harvested a 3 month male marijuana plant, and made cannabutter from all the leaves and flowers. The end result was very disappointing; it wasn't even strong enough to give a high.
