Bag seeds and cow manure when I was a teenager and a book called grow yer own stone. In the early nineties is when shit got really interesting when super skunk was bred by sensi seeds and won the cannubis cup. A dear friend flew too Holland to get the seeds and we went ballistic we grew in promix and used 20-20-20 all purpose we grew monster outdoor super skunk plants pound plants each I was into it back then for the money we grew 1000,s of them over a 6 year period the biggest year being two 500 plant plots. I am 54 this year
