Feminized Viper by john sinclair female cannabis seedbank. These are entirely female seeds of the viper strain, these female cannabis seeds produce plants that are fems only. As a medical cannabis patient John Sinclair has always appreciated potent marijuana. The powerful Viper has an intense physical effect that relaxes you without the ‘knock-out effect’ that for instance a Skunk provides. It gives the sensation of walking through the surf or on the moon while still allowing you to get on with your day in a normal fashion. John Sinclair Indica is a short, compact and fast flowering plant that abundantly produces tightly clustered, resin-covered buds that have a light but distinct herbal, almost musky scent . John Sinclair Indica has few leaves and those leaves are relatively big which makes for quick and easy cutting & curing.
