Smiley's Lingo, that may be of some help...

• Auto-flowering
  
  • Auto cannabis strains automatically switch from vegetive growth to flower stage based on age with most strains finishing within 70 days from seed.
• Photoperiod
  
  • Cannabis strains that respond to light cycles with marked changes in their growth. The flowering stage occurs naturally when plants receive less than 12 hours of light a day.
• FAST
  • Fast flowering strains are a cross of a photo fem and an auto fem. FASTS respond to light cycles and have a week or two shorter flowering time compared to the original strain.
• Regular Seeds
  • Reg seeds are as nature intended with a 50% chance of emerging either as male or female plant.
• Feminised Seeds
  • Fem seeds produce female fruit bearing plants only.
• Sinsemilla 
  • Seedless cannabis from a female cannabis plant that was not pollinated. Enjoy greater potency, effect, taste and aromas.
• Hermie
  • A girly boy! When a female cannabis plant develops both boy and girl private parts. It will self-pollinate and pollinate cannabis plants around it. Cause: bad genes or environmental stress, mainly heat and light.
• Sativa, Indica, Hybrid
  • Are terms used to describe a cannabis plant stature, short or tall, thin or wide leaf’s. Somewhere along the way effect, taste and aroma got thrown into the mix. How that exactly works I don’t know.
