- What Is The Best Temperature For Growing Cannabis?
We The Growers sits with Dr. Bruce Bugbee where he talks about the optimal temperatures for Cannabis Cultivation. In this clip, Bruce details what he believes is the best temperature for growing Cannabis, and he also goes over some research him and his team have done in regards to Day/Night Differentials.

Athena sucks
Straight to the point fantastic information, no boring intro and no annoying back ground music, Thank you so much. Cheers.
I live in Thailand and grow in a green house 6m × 12m 10 above grow fans. It's been super hot highest temp so far (greenhouse) 128.3 f/45.5c and the plants are absolutely killin it praying up all day. They've streached a bit and I'm constantly topping them. This time of year I can get 10" a week growth rate. Cross is "Gorilla Glue" × Land race "Foxtail."

Send some beans over
@@Thewonderingcheftried sending you my email YT is so F-ed up. How can I get a hold of you?
Me too!
Me 3 😂
What’s about rH ?
Dealing with hot temperatures is possible, some really love it in veg or til mid flower..
you’re not using de-hum, or air conditioner right?
I grow at around 74f and approx 50% humidity. I follow VPD and shoot for 1.35. 6 grows, zero problems and good yields...
Is that room temp or leaf temp?

this guy is truly brilliant. hes a light wizard.
I'm in the foothills of central Calif. and have all my plants, Photo Period outside. The temps are nuts right now! It has been in the high 70s and right now it is 58 and starting to rain! Two of my plants are in flower. I'm very concerned but they seem to be taking it in stride!
i live on the shores of lake huron which stays cold and offers cool nights all summer. average daytime is in the 70s to low 80s. 50/50 coco and soil and just miracle grow. ive noticed they are thirsty with the mulch, and thrive in the cool night time temps . lots of sun too and lollyypop and occasional defole. alot of nights the plants are soaked with dew. something no one mentions.
I know low humidity eliminates all problems like mold and any other problems
Youre on the right track but low humidity doesn't eliminate. It prevents. The best way to avoid issues is with proper circulation. It's not the low humidity. I run in the high 70% RH in mid flower and never had PM. Late veg high 70s, Low 80s with OGs and good (notorious for PM). So for readers, the key is FLOW. I wouldn't be surprised if low humidity with low flow would cause issues too
i dont run higher than 65% and have good air flow. Low risk of bud rot and mold issues. Even with good air flow, your lung room eventually can not handle the high humidity
Last Night i was thinking that in needed to go back to this clip! Thanks again for this ❤❤❤ cheers 4 all of you
I think when they say cooler temps at night is to bring out the colors. And only in later flower. My indoor temps fluctuate quite a bit from multiple factors but I still get quite good outcomes every time as long as everything else is on point. Right now, I'm running about 80 - 85F during the day (mostly later day) and about 60 - 70F at night in late flower. Mostly because of the light warming the tent. And because my grow is in my bedroom and I like to sleep in cooler temps. Definitely helps with bringing color out
to bring out the color of the plant you want temps of 60 F and lower, which is only used very close to harvesting when your plants is not growing or producing trichomes anyway. lower than 70F your cannabis plants will start to hibernate
No it's more complicated than that
I run a fixed temp in my lung room and the inside temp of my tent fluctuates 5 degrees (70-75 f) with the light cycle. My lights ballast is outside the tent. 5x5 tent, mars hydro FC-8000 Evo light. Week 6 flower.
UK over winter but indoors average was 7°c ❄
No bugs to deal with,
Plants are hardy as hell
Tell em again bro 😅
I think its flat comical that some of you question Bugbee's data when he literally is one of the only ones who has been studying this for a long time. There were only like 2 licenses pre-legalization and Bugbees University had one of those. We are talking years of studies and yet some of you think your bro science matters more than the expert. Comical.
Isn't it
That's the Internet in 2024, everybody knows everything, everybody's trying to troll somebody, instead of just enjoying the content taking what you can get from it and saying thanks Good job some of you show how weird society has become.
People who don’t appreciate science are just ignorant hippies and that’s really the age showing and soon we will have a much more appreciative generation of the science
I believe it does matter. The "stress" generated by the t° dropping every night helps the plant to be more resilent, they grow thicker stems and leaves. Always aim to be at least 16° at night, and no more than 23° at day. (celsius) Just an opinion.
Bruce Bugbee literally has individual testing chambers to study this. What you believe is considered "Bro Science" . What Bruce Bugbee believes comes from studies and testing done in controlled environments and controlled conditions. I'd say your bro science has less value than Mr. Bugbee's years of studies but thats just the facts.
PM has a hard time at temps in the 80s. PM likes low 70s though. You need auto watering in the 80s unless you like guessing dry back.
Put the light back to 75% 50% at the end and u can also put them a little higher too
I grow outside in Scotland wet and cold below 60 is really warm I've learnt temperature means nothing till your down to below zero hard frost will harm the plants rain not so much a problem more problems with hot clammy than cold and wet weather happy growing from Scotland 🏴🏴🏴
I drop my temps to 22 - 23•c the last week and a half of flower.
Always keep humidity at 60% right until the end and never have an issue.
I find with these powerful led lights, my plants like slightly higher RH but temps need to be hotter in veg and early flower
"Start warm and cool it off" just like nature will do, April May June July August hot which in some area of Europe is equivalent to the vegetative period, around mid-August the plants begin to flower arriving in mid-September to be around the fourth week of flowering, at that point normally the temperatures begin to drop right in the last 4 weeks of flower maturation, arriving in mid-October with temperatures ranging from 10 to 20 degrees maximum, perfect for harvesting and the beginning of drying ,very often it is enough to observe and copy mother nature to get the best results😃
The positive diff helps bring out colour though does it not?
30 degrees c is so far from 60 Fahrenheit
Love the knowledge
It will trigger reproduction, would that mean that hermies come from a too cold environment at night? Because i might be having this problem.
negative 7 heavy indica genetics in a 3 level tiers rack, 85f day co2 1500 ppm night 92f but.... got to feed at night.
mid 80 does that mean 27 degrees celsius leaf temperature or does that mean room temps??
I think so🤔
U want purple/colors u want a a 10-15 dif in that last week
Great video. Low and slow baby!
Low and slow AFTER week 4 of flower
Thanks for watching!
mid 80s in flower? sorry, bro...ive heard you start losing the first terpenes after 74. ive kept my grows that low. i honestly believe hes right in that it makes better nugs. i may not get as fat of nugs.... but i truly think theyre yummier and harder at 74 or below. Hes right in veg as well. but 85 in the first weeks of flower? no.
He is going off the data not your opinion.
I know that’s a hard thing to understand
🔥🔥🔥🔥
I just stay in the 70s, hight 60s at night
Beware of condensation on plants which leads to mildew and bud rot
83 in veg
Do you run fans at night
Always
Always
78😊
Outdoor will always be #1. Fu*k indoor and everything it stands for!!! Respect the og way of cultivation!
It’s still illegal to grow in most places
The way nature intended!
It’s a danged Weed. Water Light Air Nutrients. Different Phenos grow different plants. Period. Stop overthinking everything. Cool temps at the end will give color. But terps is terps and Trichomes is Trichomes. 50+ years growing and the worst herb I ever grew was wonderful.
Alot of new studies prove that lower temps in flower lead to more terps and potenz. U dont have to overthink if u work with facts
@@klayn1204 a lot of new studies show a lot of nonsense too. Here’s a Clue. 90% of EARTH cools off when days get shorter. Which triggers flowering in both Indica and Sativa. DUH. No scientific study needed. Because children raised by Wolves know it. And PLEASE don’t start on Autoflowers because I spent THIRTY years trying to convince people Ruderalis even EXISTED and people just like you wouldn’t believe it. Apparently they needed a scientific study too.
PHENOTYPES are Phenotypes and they ALL respond differently to practically everything. I grow Herb to get my wife and I high. And it’s been working FINE for going on 53 years.
Indoors, outdoors, Guerrilla grows and in my Garden. It isn’t a CONTEST. It’s a lifestyle. If my Weed isn’t strong enough for YOU, I couldn’t care less. I wouldn’t buy Herb from a store on a damned bet.
Outdoor definitely produces more terps as well, don't know how hed explain that. @klayn1204
@@adamw8579anything that is made artificial can’t compete with nature. That is a fact.
Terpenes are a measurable VOC. There is no study that says lower temps lead to more terpenes, it’s about avoiding high temperature. Different things. As temp goes up you begin to volatilize off the terpenes at different temperatures. If you can smell your plant, your plant and terpenes are being volatilized. The same VOCs in plants have been exhaustively studied in chambers for decades. Raising temperatures from 23C to 35C, you will see a drastic increase in TVOC. Also, I will never understand why people post “don’t overthink things” in RESEARCH. Hey dummies, research is the EXACT place to overthink things.
I'm sitting mid 70s in day and about 69 at night
As young dont do gardening they tend to Ask olders .
Big chief Say hé know nothing
This plant go to shiva illusion master of the mind
And whenbwe dont know then hé laugh 😂🎉❤
People complicate this far too much. Plants like the same temperatures we like. If it becomes hot enough or humid enough for you to be uncomfortable, your plants will feel the same way.
Wish everyone used Celcius 😂
Sweet good to know thank you
Thank you for the info 🦾
