      Growing How-To: Sexing Plants: Hermaphrodites: Male & Female Flowers on the Same Plant

      At day 21 of flower, we recommend defoliating the plants a second time, and while removing all the leaves from a mystery plant we started from seed, we discover it is a hermaphrodite- it has some male flowers developing along with the much-more-obvious and plentiful female flowers! Not wanting to let it gets seeds in the rest of the crop, we have to toss the plant 3 weeks into flower- one of the hazards of starting plants from seed.
