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.

It will trigger reproduction, would that mean that hermies come from a too cold environment at night? Because i might be having this problem.
Last Night i was thinking that in needed to go back to this clip! Thanks again for this β€β€β€ cheers 4 all of you
negative 7 heavy indica genetics in a 3 level tiers rack, 85f day co2 1500 ppm night 92f but…. got to feed at night.
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.
Itβs 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.
Wish everyone used Celcius π
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
It’s fairly obvious that some cannabis genetic respond differently to others regards light, temperature, ‘diff’, humidity etc and that there is not a singular answer to questions like ‘what’s the best temperature?’. Best for what? Pure Kerala? Afghan from the desert? Pakistani from the low Himalaya? Thai from Chiang Mai? Sativa from Lesotho, or Zamal, or Panama? Different genetics different answers. Look at their native environments.
Outdoor will always be #1. Fu*k indoor and everything it stands for!!! Respect the og way of cultivation!
this guy is truly brilliant. hes a light wizard.
83 in veg
Thank you for the info π¦Ύ
I’m sitting mid 70s in day and about 69 at night
Idk if i belive this guy.

mid 80 does that mean 27 degrees celsius leaf temperature or does that mean room temps??

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 live in Thailand and grow in a green house 6m Γ 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" Γ Land race "Foxtail."

I know low humidity eliminates all problems like mold and any other problems
Stupid question here…. Is that kronic? Kinda sounds like him
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 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 π΄σ §σ ’σ ³σ £σ ΄σ Ώπ΄σ §σ ’σ ³σ £σ ΄σ Ώπ΄σ §σ ’σ ³σ £σ ΄σ Ώ
Do you run fans at night
Great video. Low and slow baby!
Straight to the point fantastic information, no boring intro and no annoying back ground music, Thank you so much. Cheers.
U want purple/colors u want a a 10-15 dif in that last week
I drop my temps to 22 – 23β’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
Bless this guy for using Celsius some times
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.
30 degrees c is so far from 60 Fahrenheit
UK over winter but indoors average was 7Β°c β
No bugs to deal with,
Plants are hardy as hell

Love the knowledge
I grow at around 74f and approx 50% humidity. I follow VPD and shoot for 1.35. 6 grows, zero problems and good yields…
The positive diff helps bring out colour though does it not?
I believe it does matter. The "stress" generated by the tΒ° dropping every night helps the plant to be more resilent, they grow thicker stems and leaves. Always aim to be at least 16Β° at night, and no more than 23Β° at day. (celsius) Just an opinion.
Depends on genetics as well massively im growing mimosa and that does not like anything above 26C in veg and around 23-24c week 3 until harvest and at night 18-20c is good brings the purps out for sure under 20c
I just stay in the 70s, hight 60s at night
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.
Put the light back to 75% 50% at the end and u can also put them a little higher too
"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 resultsπ
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. 5×5 tent, mars hydro FC-8000 Evo light. Week 6 flower.
Sweet good to know thank you
A negative temperature differential can slow stretch, letting night temps be equal to day or even slightly higher. Neat trick i learned years back.
Anyway this is a good length and intelligent thanks.
As young dont do gardening they tend to Ask olders .

I would have appreciated trich porn, with a real lab microscope!
Very nice talk. Thanks for sharing this.
