The best online cannabis schools for growing weed

Table of contents

Anyone who has grown, harvested, trimmed and cured their own cannabis knows how great it feels. But what about the rest of us? For cannabis fans without a green thumb, growing weed can feel like an advanced science best left to the professionals, and so confusing as to be a non-starter. 

Luckily, you no longer need access to a grow room, an in-person course, or any innate gardening skills to become a weed grower. With an online cannabis course, novices can become great cannabis growers, and seasoned cultivators can become master pot farmers.

Ray Murphy 

The quality of instruction is what impressed me most about these courses. That, and the quality of networking and social interaction with the other students.

Kim R

For people who want to learn how to grow cannabis indoors with a professional level of quality and output, look no further. 

Oaksterdam University’s horticulture certification program “provides the most comprehensive indoor horticultural education available for entering the Cannabis Industry and expanding your personal growth,” according to the company, and comes packed with resources, presentations, grow labs, and mastery exercises. 

All of the curriculum was developed by the university’s very impressive faculty of cannabis experts, and starts off by teaching students all of the basics of federal and state law and how to navigate encounters with law enforcement.

The course then runs through seeds and clones and how to get set up before diving into feeding and watering. From there, students are given a deep look at the hardware used in growing cannabis indoors, followed by the growth cycles of the plant and how to optimize growth all the way through the drying and curing. The course also leaves a lot of space for covering what exactly you should do when things go wrong (because they probably will at one point or another.)  

Oaksterdam University is one of the most well-known names in cannabis education, and since 2007, more than 40,000 students have attended its programs. In addition to the curriculum, those students have been able to benefit from a job-world, real life exercises, and an education that can potentially help them find their way in the cannabis industry.

I have to admit, I was nervous just starting out, but all of my guy friends who grew up were very impressed with my first crop. Who knew this girl had a green thumb! They said it took them years to do what I am doing, and I have everyone at THC University to thank.

Aaron G. 

A great introductory course for those with little to no knowledge of cannabis. I appreciate the explanations of each major strain.


Not every grower is looking to make it a job, a side gig, or anything other than a hobby. 

The Grow Basics Certification from THC University is a solid option for anyone looking to learn the ins and outs of cannabis cultivation, so that their indoor grow at home will turn out some buds they can be proud of. 

The course doesn’t seek to load down the students with any sort of technical knowledge they don’t need or deep dives on cannabis law and the like. 

This is a stripped down course that can truly give beginners the confidence and knowledge they need.

Alexander Malik 

Green Flower’s Cultivation Certificate Program is exactly what you need to get into the commercial cannabis industry. The knowledge, skills, and credibility you get by going through this program is exactly what cannabis companies look for when deciding who gets the job and who doesn’t.

The cannabis studies program covers a wide range of subjects beyond cultivations, including the cannabis industry. Cannabis law, medical and adult use cannabis, introduction to business and topics in cannabis. 

In the cultivation curriculum, students cover  seven different topics – seeds and seedlings, vegetative growth, clones and cloning, cannabis flowering, before harvest, harvest and drying, and grow rooms. 

The course is designed for all types of students Stockton university says, but more specifically “Anyone who is in or aspires to become a part of the cannabis industry, or anyone interested in enhancing their knowledge of the industry.”

Why take an online cannabis cultivation course 

  • To finally learn to grow weed 
    An inline cannabis course can provide the knowledge students need for when they want to finally grow their own weed – even if just once or twice. 
  • To boost your weed growing skills
    Cannabis cultivation programs also target students who already know how to grow weed and have had a successful harvest or two. For these students, the courses can really go deep into the details of how those successful harvests worked, and what they can do even better the next time around. 
  • To help your job prospects 
    If you’re looking to work in cultivation – or you’re a cannabis professional who would like to present a more well-rounded body of work experience, a cannabis cultivation course cna help get you there. 
  • To gain a deeper understanding of weed 
    The experience of growing your own weed is fulfilling in its own right, but it also helps foster a deep appreciation and understanding of the plant in a way that someone who has never grown cannabis would not fully understand. 

How online cannabis courses work 

Online cannabis courses are a great example of remote learning at work. 

These courses and colleges are typically staffed by a combination of educators and cannabis industry experts (including cultivators) who also take part in the creation of the curriculum. The lectures are typically given by video. 

Students who take part in online courses are typically able to complete the coursework at their own pace – remotely, from any location in the world, without ever stepping foot in a classroom. 

Most but not all cannabis courses also involve quizzes and graduation requirements that must be met in order to complete the program. 

Online Cannabis classes typically provide a certificate upon completion, which makes them perfectly suited for would-be cannabis professionals who want to improve their cannabis knowledge and stick out from the crowd a bit more.
