    First off the course is very well laid out and very informative. The topics are clear and easy to follow. The pictures are a huge help. I have some feminized white widow auto in my grow box right now under a DWC style. I will let you know how they turn out. You my friend are the real deal.

Who is mr Bergman?

My name is Robert Bergman, founder of the I Love Growing Marijuana platform and author of the Marijuana Grow Bible.

For the past 20 years I have been growing marijuana in and around Amsterdam. Starting out in small home-based setups with just 5 plants, moving on to industrial sized indoor plantations.

Those days of large scale growing are behind me. Now I am on a mission to share my knowledge about growing weed. In two decades of growing I have tackled about every problem there is. From plant care, to security, from obtaining quality seeds, to harvesting and selling. Now the time has come to share.

Will you benefit from my mission to “teach the world to grow marijuana”?

With signing up for Bergman’s Lab, you will have insider access to the very best I have to give.

Don’t learn from your mistakes, learn from mine!

    Hey Robert, so far so good! I will say that your course has taught me more in one night than the thousands of dollars in publications. I have it all from Ed Rosenthal to George Cervantes. When I was finished reading all these books I said to my friend there is something missing, it seems that you had to look between the lines with others. I am in the middle of a grow right now and am hoping I can salvage some of it with this new info. I am glad to have your course now and I hope to finally do this right!
