I am relatively new to growing and to this site and I constantly see various references to different strains of 7 Pot such as Brain Strain, Douglah, Yellow, Jonah, etc. Are these all crosses that different growers have stabilized? What is the difference between a regular 7 Pot? I have some of the regular ones planted and all these others are sounding very (much more) intriguing! Sure would like to acquire some seeds
