Finally, a grow video that doesn't start with
" heyyy tuuube!"

[MagnificentlyHighAlien]

As a first time grower, these types of videos have been more informing than any grow guide because of the detail of certain aspects.

When somebody has a doctorate and looks like my stepfather starts talking about cannabis I open my ears and shut up and pay attention!

[Student-grsq]

I never thought I'd pay this much attention in school. Well played.

[hypelogo]

Finally, someone that knows wtf they're talking about. Thank you.

[bedward]

When the student is ready the Master appears.

[kreature]

The weed that this guy grows makes you permanently high.

[ReallyTYReal]

Sir it was a honor to get this lesson from you, thanks for your contribution of actually GOOD information on youtube.

[kxspy]

Wow, Dr. Bugbee motivated me to study something in my life after being lack of motivation for years. Thank you so much. I loved the video.

[mart]

Sure would appreciate seeing all the other 8 of the 9 cardinal element modules, specifically for this plant. Thanks for all your work Bruce.

[devjyarn]

I'll be the first to say yes please to talks on the other 8 parameters in regards to cannabis! Thanks for putting out such useful information.

[shawnewaltonify]

Dr. Bugbee going above and beyond selling instruments in this service to community. Thank-you for explaining this, it is critical that we know it, and you care that we do.

[BrendonLeaman]

I've been growing for 10 years and the minute this video started playing I was watching the screen like a kid sitting in the front row.

[DanielBowens]

After watching all of his videos I feel like I should be getting some kind of certificate or degree in the mail 😂

[lucasberard]

Thanks for this. I really like to see things broken down into their separate, quantified components. It lends clarity. I'm no stoner, I've battled PTSD for years, with limited results. I finally decided to try Cannabis, after getting a medicinal license. I have not slept so good in over a decade. It seems to eliminate my dreams, which I have had ONE good one in 15 years. I now intend to grow it along side our Hibiscus and Sugar Cane. I love the science behind it. Great job. Thanks again.

*Pauses* _ "Cannabis looks something like this" _ *Draws curve with affection and clearly shits on the lettuce curve* _ Tells us to "Look at this curve, look at that curve." twice _ Proceeds to a wholesome "Woow" _ Ends it all with "This is cannabis" _ *Writes it down with intent to kill* Hahaha these are awesome lectures! Thank you for sharing some knowledge in such an accessible way!

[Jclarine]

Great information, I would love to see a series on the individual environmental factors affecting growth for Cannabis. Thanks Dr. Bugbee, I miss being in the Crop Physiology Lab with our class. I've gladly paid thousands of dollars to Utah State for information this valuable, it's amazing to see it made free to the public.

Thank you for sharing your knowledge, we can learn in a week what took a lifetime to study

[Voidwalker]

This guy is such an effective teacher! Been trying to learn about this but I haven't found anything as in depth as this video. Worth watching till the end even if you already have the knowledge.
