BAM! This class was great! I was confused by all of the different information I found on the internet about indoor growing. I would wholeheartedly recommend taking this class of you want to learn how to grow at home. I’ve been growing for a few years, and after taking my my class, I realized (finally) that I didn’t know what I was doing these past years! I harvest this month and everything looks bigger and better than before. Thank you Grow School. Martin G. -Gloversville N.Y. 2023

I have been trying to learn cannabis horticulture to better my chances of getting a job in the industry here in Colorado. This class helped me get a better than entry level position at a large grow. I have been there about six months so far, and they just offered me a supervisory job. Thank you for The Grow school. Justin T. -Glendale CO 2021

My class was exactly what I needed. There is a lot of conflicting information out there about growing successfully, indoors and the instructor guided me through the techniques that work the best. I am excited to start legally growing! Craig N. -Portland OR 2020
Thank you. Josh L. -Fowler CO 2019

Just checking in! It has been almost 3 years since class, time flies! I learned so much in class. I have been working all year at Strainwise (which has 9 dispensaries) in the 60,000 sq ft cultivation warehouse, doing every job, but mailly in the clone department. Thanks for the class, so important to get me started and obtaining a job. Perhaps, next year, my own greenhouse facility! Mona G. -Denver, CO 2017
I attended your class in August 2015. I just want to say that I got a job at Terrapin Care Station in Boulder! The medical warehouse. I’m so excited about this! It all started for me with The grove school, I appreciate your attention. Leo C. -Boulder, CO 2016
Instructor David had the ability to present complicated scientific growing information, in a simple and easy to understand way. That helped me easily understand what he was talking about. I now have a much better sense of the big picture common in a great sense of covenants for growing. Ray G. -Denver, CO 2016

I’m extremely pleased with the information contained in your online self paced 12 hour class. I’ve only completed 10 hours so far but I will be finishing today.

Thank you guys so much for the wealth of information and easy access to it. Jeremy D. – Hamilton, Ohio 2015
The Grow School in Denver is very professional and knowledgeable. I highly recommend them for growers of all skill levels. They have an excellent garden support team. Overall AAA+++ experience! Captain C. -Sartwell, MN 2015
(David) You’re an awesome teacher! I’m looking to start a cannabis and CBD edibles company here in DC. Holly D. – Washington, DC 2015
I attended David Degraff’s course Grow 101 in March in Washington DC. I believe it was a very valuable course. Mr. Degraff obviously has decades of experience. What I thought was extremely important was how Mr. Degraff was able to communicate technical concepts into a language that I was able to understand. He made this scientific discipline incredibly accessible. I look forward to taking more courses and learning how to implement his technical expertise. If you have an interest in this field of study and The Grow School is touring through your region, I highly recommend you consider attending a class. Anonymous – Washington DC 2015
I attended and completed the march Washington DC grow 101 class. The presentation style was really helpful to translate technical concepts into layman’s (me) understanding. The e-book is a terrific resource. Gary C – Washington DC 2015
First let me tell you how much I enjoyed The Grow School. You have definitely done your homework and it showed. Thanks for a most informative and educational six hours on Saturday. You have a tough job. You have to get people up to speed not only on botanical theory, but plant pathology, genetics, propagation, photoperiodism, and growing climate – each of which are 4 semester hour great undergraduate courses. I have put it with my college texts as a reference volume. Basic theory I knew, but the nuances of all the disciplines as they specifically relate to cannabis are a quick to the point reference. The handbook alone is worth the cost of the whole course. Again, thanks for a most interesting Saturday. Robert E. (Master’s Degree Horticulture) – Alhambra Illinois 2014
I loved the class, it was very informational. I am going to keep educating myself. Thank you for the great experience. Jesus G. – Pennock, MN 2014
Hi! Hope everything is good. Now it’s getting a little bit colder here in Brazil. The summer is going away! I am in week 2 of flowering. It’s looking great! Take care! Bruno B – Rio de Janeiro, Brazil S. A. 2014
I learned more in the elevator on the way up to my class at The Grow School, then I did in that entire other “Grow University” class I took in Denver…. Andrew K – Fort Myers Fl 2014
