Feminized vs Auto vs CBD Seeds

Feminized Seeds

Oxide-free buds with no male worries. Best for indoor grows or outdoor flowering-focused efforts.

Autoflowering Seeds

Fast, compact plants—ideal for seasonal climates or stealth grows. Lights-on 24/7 until harvest!

CBD Seeds

Perfect for users wanting therapeutic effects but less of a THC high. Often easy to grow and discreet.

Private cultivation is permitted under.

Warning: Public use, sales, and distribution remain illegal. Make sure you're growing in a private, secure space away from from minors.
