Great video, thanks! I learned from Kymron DeCesare, at Steephill Labs, back around 2014 that pruning had no affect on biomass or cannabinoid yields. So I’ve been removing everything at end of week 3 and 7 of flower ever since with no issues. I didn’t know more info was needed to prove it.
Are aptus high concentration good ?
4:32 Its interesting to see cannabis behaving somewhat analagous to say vinis vinifera (wine grapes) in that too rich a soil/nutrient environment reduces the desired production (eg THC+CBD for cannabis & grape quality for vinis vinifera), whereas mild stress or even deficiency increases same. Conclusion: instead of being kind to our plants, we need to be more ... mean. 😂 /cracks whip at nearby sativa 😈
Organic. Or no organic fertilizer .
Thank you for helping me out. I appreciate it
I wish I knew how to calculate my liquid fertilizer dilutiob so as to achieve 60 to 120 mg per liter.
Whats stopping people from buying delta 8 and putting delta 9 in the packaging?
This greatly explained pros and cons. Thanks
Great study! Like your others. But I think it's half the truth. Fertilising cannabis consists of two parts: The first is nitrogen for growth and the second is phosphorus and potassium for flowering. So the final question is whether a higher growth rate of the leaves could result in bigger flowers or THC/CBD. May be it's a theme for a following study?
Hello, great video. Is there any information on the time and/or frequency these plants were given fertilizer? Was Urea the only fertilizer used over the course of the entire study? Sorry if it was explained and I missed it.
were the authors studying applied N throughout both veg and flower phases, or N through flower phase only? Old school advice had always been to stop supplemental N at flower phase... so I understand this study to confirm that advice. BUT - if high levels of N during veg phase are detrimental - the I missed that message here and will need to review the source. Thank you again for sharing these studies - I appreciate the value you have added to our understanding - and business!
Do high N and high amino acids effect plants cannabinoids the same?
amazing video!!
You can buy a beneficial bacteria you spray on the plants in vegativ growht 2 weeks before you force flower use it 2-3 times a week for 2 weeks , cause its not in flower it gets the infektion but in veg ,an wen the air humidity and temp are in favour of the mold it will grow an fuck your plants up , please try this too prevent as far as i now it can be used for vegans and are not dangerous to human health. You can buy it at your local growshop beneficial bacteria for gray mold ,brown mold
Great video. Please improve your mouse cursor visibility though :)
I'd love to be able to listen and watch a stream or podcast with you, Harley smith, Bruce bugbee and other people cannabis experts!
This is interesting. It seems highly dependent on soil type and chemistry too. In southern Oregon where the soils have super high levels of magnesium, hemp farmers that added access available nitrogen saw a dramatic increase in THC levels. Studies conducted by OSU determined it was the access nitrogen farmers were adding.
as a first time hobbyist grower ive read this and other studies. everyone told me that my off the shelve tomato fertilizer is bad in bloom (5-1-2) but looking at papers out there, finding a rough average gives me 5-1-3.5 (see below), which isnt far off, and closer to an off the shelve tomato fertilizer than all those expensive cannabis marketed "bloom" products. im not sure how to convert milliliters into milligrams on say 5ml/L of (5-1-2).. can i just calculate it with mass of N? but that would still be far off diminished returns due to overfeeding N is my guess. seems over-fertilizing N is much harder to do than stunt growth with too little and for a beginner like me its probably better to go a little heavy on N.. (thinking out loud) ------------------- Zheng, 2021 (1) N 194 mg/L P 59 mg/L K up to 150 mg/L Dilena, 2023 (2) N 60-210 mg/L Saloner and Bernstein, 2021 (3) N 160 mg/L Cockson, 2020 (4) P 11.25 - 22.5 mg/L Bugbee, 2022 (5) P 25 mg/L Saloner and Bernstein, 2021 (6) K 60 mg/L Yep, Zheng, 2020 (7) K 150 mg/L (∼2:1 ratio with N) ----------------------------------------------- N-P-K ⌀ [156] -[29.4]- [105] ~ 5-1-3.5
A good starting point..... Veg...15-5-15 +5% .ca + mg Bloom 10-30-20.
I'm trying to find that sweet spot now. Thanks for the science!
Good luck and thanks for watching!
thank you!!
You are welcome!
Huge thanks!!! Pls don’t this for all of the nutes 🙏🏼
You are welcome, another video on Mg is in the works;-)
Very cool 😎
such a beautiful field at the end!
Thanks for watching until the end... it is worth it;-)
good info.
Glad it was helpful!
Q: Do trippy mushrooms in the soil influence the cannabis plant?
Not sure.
You're back!
Thanks for the welcome more videos planned soon;-)
Grow your own. Don't trust anything that's in a Dispensary for sho.
Certificate of Analysis is an important document...
Thanks for the videos❤
No problem 😊 Thanks for the viewing and comment!
🙂❤👍Thank You it has been a long time in between videos Great seeing you and your Great information you provide. 🙂❤👍
Yes, a little while since the last upload, but there are more planned to come out this month so keep an eye out;-)
@@DeBaccoUniversity Looking forward to them 🙂👍
My my
??
@ Professor D, is using Bud Candy on your plant affects both cannabinoids and flavonoids of the final product?
According to the manufacturer it does, but no studies have done a scientific comparison of this product.
Once again fantastic information for which I can only say thank you so much 😘👍🏼
You are welcome and thanks for the subscription!
You are the best KZreadr ever! Pure information no games or click bait.✌️🖖🙏
Thanks for this wonderful comment! "Pure information no games or click bait." That is the intention of this channel, be sure to share it with others!
Couldn’t agree more
I would like to see how miracle grow affects terpenes. I have done experiments as far as one garden natural and one with miracle grow in the same season. Miracle grow continually performs well. So does a cultured soil, but Miracle grow seems to make slightly bigger greener plants.
it does especially week 5 through 8.
Ugh
@@TimJameson-jg8sl stunning response
Working on a video comparing mineral based and organic based fertilizers on cannabis yield so be on the look out.
Urea
is that high nitrogen during veg, flower or both stages???
Nitrogen rates were kept the same for the full grow cycle.
@@DeBaccoUniversity i see. is there a study where high rates of N at veg then low rates of N at flowering. as i think that is what more people would be doing. thanks great video as always
@@uncle_creepy2743that's the old school standard and the one that I believe produces the highest yields of thc/cbd. The most successful hydro growers I know completely stop supplemental N as soon as they shift to flower light phase. But it is good to see real science confirming truths and rejecting myths. Cheers
I would like to say I have been a subscriber since the pandemic. Had my notifications turned on and thus video. This video right here popped up today. Excellent work just sad I've been missing it
It takes a lot of time to generate the content, but the goal is quality over quantity here.
Wonderful.any work on adding silica?the dos and don’ts?
Thanks for the subscription and check out this DeBacco University video on Silica... kzread.info/dash/bejne/m4mGmbFteNmbY6w.html
ty for the Video, great information as allways !
You are welcome!
Hello, thanks for your videos. As I interpret the results the use of nitrogen is a sigificant factor in increasing the yield. And even if the cannabinoid ratio is lower, the total content should still be much higher with high nitrogen until a thresholf, I would consider as overfertilisation. I'm worried people will mistakenly interpret the video as, Nitrogen is bad for cannabinoid yield. Furthermore, I would like to ask for a video regarding the optimal NPK Ratio, and if it needs to change for flowering period or not. I checked all your fertilizer videos, and never seen that topic specifically mentioned. Overal it seems, that grower use way to much P and way to less N, since there is this myth that P is the main driver of bud growth. Bruce Bugbee e.g. recommends a 212 ratio through all stages as optimal.
Excessive nitrogen can negatively impact yield, but visually improve plant growth.
Alright, well, let's put this "Professor" jazz to rest, shall we? You are The Dean of Green, sir! Plus, it's been a while since I've said thank you. So, thank you for another superior and helpful explanation of things that I can actually understand. 😃👍
Wow, thanks! Interesting title... "Dean of Green";-) More videos set to come out this month so keep an eye out.
Great seeing you
Happy to be seen... even if it is just a small box in the corner of the screen;-)
great vid. is there a way to diagnose if you have too much N in ur soil? would it be visible like N toxicity? p.s. ur the best source for growers on youtube and ill die on that grave
i think if leaves are really deep green is an indicator, but ill let the expert speak
Too much nitrogen in your soil IS nitrogen toxicity.The leaves will look beefy and go a ridiculously deep shade of green.
Deep green is typically a key indicator along with brittle stems. Thanks for the comment and more cannabis related videos coming out this month;-)
i'm number one
That was fast, happy to provide you with fresh new content.
Yeah great! You have won the ashtray of Jesus Christ. The original one.
Which will likely cause disease and stunted growth. Was the water tap water which has chlorine and chloramine with flouride?? Why wasn't this included in the study?
Full link to study provided in description.
Chlorine and chloramine will kill the beneficial microbiology in the soil.
Knowing the levels is important and it is unlikely it will be able to sterilize the soil.
Hi, I'm a bit confused because in the dosage table you mention Na2S2O3 x 5H2O, but the picture on the right shows Na2S2O3. Is there a difference in which one is used? Cheers
See time stamp 6:25 for full instructions.
Thank you
You are welcome!

Glad you liked it!
Thanks for the info
No problem 👍
Perfect
Thanks!
A funny thing about male plants if you put a leaf in the microwave the male will give off sparks but not the female
Not sure the "Y" chromosome has this reaction....
@@DeBaccoUniversity That is how I checked in the 80s before things got high tec.
