I've taken a lot of classes, read tons of books and everything else and Harley makes everything simple, easy to understand for everyone, and then explains how you can actually make real changes to fix a plant's issues to grow amazing plants. Thank You Harley & NPK for giving people the control over their plants and educating us all in how to be experts.
Over the years I have seen and heard of many persons claiming to be so called ''plant doctors'' but for Harley this title is well deserved in my opinion, he is absolutely in a class of his own. Thank you so much for sharing your knowledge you are a 1st class lecturer.
In my opinion Harley Smith is by far the most knowledgeable speaker about plant growth and biology I've seen so far. Keep up the great work! Never lose that passion.
How nice it is to see such a capable and passionate person explain a subject with such wisdom and commendable disinterest. When this happens is when I think how lucky I was to take English language classes. This brings me closer to the knowledge and to enjoy a real lesson in Agronomy. From my beloved land of Argentina, I stand up to applaud you master.
Harley Smith is my new hero! I really like how excited he gets teaching about plant anatomy and nutrients. You can see he enjoys teaching and it makes me pay attention. Thanks Harley, for all you do.
I've taken some of Harleys classes he is the best and he really knows his stuff. He is taught me so much about the elements that I am getting explosive plant growth in everything I do and now I can almost immediately diagnose what each type of plant wants or likes. NPK makes excellent products too, they're very concentrated and a little package will probably last you years. You can tweak things at specific times of grow or bloom and what they are is the raw materials every major fertilizer company's fertilizers. Except they're in the most valuable dissolvable form and top-notch. I like them so much I become a dealer. And yes this does apply to the marijuana cannabis industry as well. Many people want to know that because they are growing their own medicines and want good production and the highest quality. Harley can definitely teach you everything about quality. I'd rate him as probably one of the best plant biologists in the world, and he's been all over the world. I periodically come back to his videos to refresh my experience so I don't forget things. Sometimes it does take a while to absorb but if you do it over and over again you'll get it and you'll be glad you did. Thanks Harley and thanks NPK for this video. You guys rock. Robert Sandera
Hi Robert, thanks for the compliment! It's a good idea to always be learning and re-learning things we've forgotten. If Harley is still constantly learning new things, so should everyone else! Peace!
I just ordered your whole line of products Harley. Your videos are on speakers in my house on loop daily lol. For so long I've been annoyed with nutrient companies because of the fact that we don't have control of the multiple ingredients/macro micro nutes that they load into there products. Im hoping to have a more tactical and direct way of feeding with your products. They'll be here in 2 days. Keep it up Harley and NPK, we're watching
Dont count out shop lights just yet. Lithonia cp high bay shop lights at lowes now has a full spectrum light in either 4000k or 5000k with high blue high red and shockingly higher greens and yellows and oranges. Half the price of a* grow light* all of the benefits. A 200 watt 400 equivalent [18k lumens] will grow 4 medium plants in a 3x3 tent. I've done extensive research, the lights are solid!
I have watched this video probably 200 times (yeah....I ain't got shit to do but watch plants grow). I always catch something new almost each time I re-watch Harley Smith videos. Today I learned "I NEED TO BACK OF THE POTASSIUM!"(29:48). I frequently have an issue with just a few leaves turn yellow here and there during heavy flowering and I thought it was a Mg deficiency. I now think it's the extra Bloom, PK Boost, and added NPK RAW Potassium I'm feeding my plants during flowering that is giving me a potassium toxicity.
Thanks Harley your videos are full of valuable knowledge. Its great you do this for free an no gain, teaching us information its taken you years to research. Ive watched 4 or 5 seminars from you and have learnt lots of valuable information I'll implement into my hobby. So I thank you for your effort and time.
24:43 id love to know how you feel about VPD recommending people 65-70% RH at 25 degrees C, they stick humidifiers into their grow rooms to follow some VPD chart they have literally no idea what it means or why they follow it, just the internet said so..
Man thanks so much for this and all your videos! This video has increased my understanding of how everything works and has brought all the scattered information I've learned full circle! You have a great way of teaching and making these things understandable, thanks again.
Such a wealth of knowledge being shared thank you for these video's they have been really helpful and the way you explain everything has been real easy and fun to learn from you. I have been using the florescent 6500k and that has really kept the plants from stretching during veg that really helps when growing indoors. Thank you for sharing
I have & use ALL the RAW/NPK products ( single elements & all in 1's) + ( grow/bloom microbes) use for all my indoor grows, very potent & you can use so many ways for Tea's, foliars, soil/coco coir drench. outdoor grows i use Down to Earth dry amendments but still make a tea or foliars = kelp, humic acid, compost or worm castings, for seedlings Vita-b very small kelp+ phos+ rhizo's roots love it. HIGHLY recommend using RAW/NPK products to any grower. Amazing products
You provide high quality education 👌 .. Thank you so much for the science.. simply the best source I have come across in all my reasearch. University quality !! Cant thank you enough for this learning . 🙏
We grow corn in the Texas Panhandle. When we first started growing corn after getting my Soil Science degree in the 1960', we were planting after the last frost in April. The experts from the Midwest were giving us bad information. What you said is factual because now we plant around June and make much more yield with shorter season corn and less water per bushels. We are now producing large field average of 17,000 lbs of grain corn per acre beyond what the Midwest can do because of our light spectrum through the season.
Our long season is 119 day corn while our short is 103. We plant the 108 to 111 for max yield. 101 to 103 is what is planted in Wisconsin. The shorter season can be planted to vegetate with blue light in summer to mature when we have more red light and less blue. Our Spring can be hell because of the tremendous amount of solar energy but good for cotton.
Awesome video! Trying to get into a little gardening armed with years-old animal/human physiology background, but very little plant physio knowledge. Video was very helpful. Thank you.
Thank you for sharing your wisdom, your dedication, and intelligence. Question: What is a proper PPM of Phosphorous for germination? I'm attempting to mix my own germination formula to increase germination time, I also scarify my seeds, so any information would be helpful thanks.
Thanks Harley.... this is awesome video very easy to understand how plant anatomy and nutrient amandment. I'd love to share this chanel to our group of Indonesian farmer.
1st video ive watched on your channel. Really quality info, subbed. Expanding on my comment here towards the end of the video... you sir are the plant messiah, wife learning horticulture and loving the info, myself growing too am a big fan 9f your knowledge. Excellent
Hello. Regarding UV lighting. Any recommendations on placement or distance from the plant and how much time. I would like to supplement with UV light tubs.
I am a grower and new to NPK-University and the RAW product line. I also have a concrete sequential learning style. Learn the basics an build upon them systematically. I like to begin at the beginning and progress systematically. Is there a recommended order in which to view these videos or do I just jump in, kick my arms and legs around and try to learn to swim? Advanced thanks.
Probably complete Plant Nutrition gives the most broad overview on nutrients in general. I'd watch that first, then all the others in no particular order.
Hi Harley Iv got some tropical plants growing in the uk, am watering the plant with potassium sulphate when i water the plant it has developed flowers on the plant, an trying so my flower does not fall of. Any other advice? Plant are in soil
hello Dr Harley Smith, can you tell me about the benefits of putting kitchen waste into my yard? I am talking specifically about liquid waste, like.. the water you boil potatoes, corn, etc in the juice from a pickle jar excess fats? Do these have a benefit to putting on plants?
i recently attempted to take em1 and add your product of molasse to it in a 10l container with 500ml of em how much molasse do i add i calculated 1/4 tablespoon and it never finished is this due to the wrong proportions of em1 to molasses
England says High.Thanks for the lectures.Just watched the one with the info and Amino Acids.I got a bottle of the new Amino Treament from House and Garden,the Dutch Nutrient Company although I mostly use Advanced.Their Roots XL is a product Iv used for a number of years with amazing results.Matey who owns Advanced Nutrients has done a YT post raving about it saying its better than his rooting products.Says an awful lot.
No bongs,no stupid music, just real education great video 🤘🏼 life's a garden dig it 🤠
Playing this content in my backyard so my plants can listen to it too.
Lol
I should do that too. :D
Hehehe. Very good.
Play them classical music or jazz when they are awake. Just like babies it promotes health and better growth 🎶 🎹 🎷
But the plants already know what they need
This never gets old. Thank you a million times Harley!

Thank you for watching our classes :)
best horticulture lectures on youtube period!
Thanks so much to Harley Smith for producing and sharing these easy to follow, educational videos!
He references some very technical and fascinating topics in passing reference. His knowledge is legitimate and captivating.

Harley is definitely one of the best teachers I love his voice and enthusiasm about what he is talking about
The ppl that disliked this video must be upset he's sharing the knowledge. Thanks for explaining it simply.
You are what they call "Gold" in the grower community!. .Thank you!
All hail Dr. Smith lol
Always keep coming back to learn, and refresh on all things N-P-K! Micro and Macro nutrients always important to remember!

If there was teacher like you Harley-Smith at the school and even at the church we would we will be the best of the best growing human.
Period.
Totally
The best I’m listening to so far……Outstanding
Excellent video explaining the NPK and what the relationship is between the various elements and the plants.
These lessons are an absolute gold mine, no longer wasting my time on all the other RUclips hacks.....Thanks!
thank you so much. There certainly is a lot of "information" out there...
Your energy is mobilizing even more than plant nutrient an mineral transport! Subscribed!!

I just watched a movie about a rich farmer in the Panhandle. It had Richard Gere in it.
Awesome video! Trying to get into a little gardening armed with years-old animal/human physiology background, but very little plant physio knowledge. Video was very helpful. Thank you.
I'm naming my first cross after you Harley OG. Much respect, my man!
Is she ready yet?

Absolutely brilliant. Thank you so, so much for making this information available.
Hi, at around 8:50 you talk about over watering, how would this apply using coco canna plus as a medium? Thank you
You use the base nutrients during flowering?
you are a great instructor, i'de bet your garden is magnificent
Best instruction and guidance ever given
I'd love to see the lecture covering light spectrum specifically.
You (or anyone interested) can use the coupon ' seethelight ' for 25% off Harley's video lesson on 'Light Recipes'. Happy Gardening!
I know this is old video but the video you're referring too is now available on RUclips for free. I just watched it for the second time this year.
Dr. Bruce Bugbee also has a pretty nice light spectrum video as well, both of these 2 have an amazing passion for plant life

so what is a good fertilizer that has the right ratio to give them when they go into flower??
You have an answer for everything so much knowledge but yet not smart enough to have all your videos transcribe and put it up for sale❤

Incredible knowledge presentation.
Fantastic video. Slowly becoming a better soil/hydro grower. No more planting then fertilizing willy nilly.

Very informative. Thank you for posting
Thanks for watching!

If you add just regular table sugar to your cannabis plant in soil
Will it bring it harm? Or good?
This is an amazing video. So much good information. Did he stop making videos 😕??

If you over water the soil, no oxygen can get to the roots. Does it work in hydroponics?
