My name is Robert Bergman and for the past 20 years I've been growing marijuana in and around Amsterdam.

I started out in small home-based setups with just 5 plants and slowly improved my techniques until I was growing industrial sized indoor plantations.

Some words on the Manual

  • …I DEFINITELY RECOMMEND TO NEW GROWERS!!! They make it fun and easy for new growers to be able to order the seeds and start growing immediately after receiving your seeds!!

    Robert’s grow bible explains everything you need to know on how to grow the best and explains things in a manner very easy to understand. These guys are the real deal, was skeptical at first but they are now the only bank I use.

  • Followed what I read in the Marijuana Grow Bible and my plants are now amazing. I won’t have to visit marijuana dispensaries for the good stuff ever again... and it also saved me money. Thank you!
