disrupt86 Reviewed by disrupt86 on . Sexing Mother Plants I want to sex my mother plants. Can I clone them and then immediatly put them on the 12 hour light regimen? Does it matter how tall or mature they are before they'll show pistols in the bloom stage? I just want to know which mother plants are female so I can pull the males and stop wasting space. Rating: 5
