The definition of a weed is an unwanted plant in a garden. Cannabis is now a production crop when you are growing it for a living to pay your bills. When you have invested substantial amounts of money and are trying to make a decent living in a competitive industry then testing different climates isn't exactly over thinking it. I agree different lineages require different climates, drybacks and ect. I also find testing out what works and making subtle changes is the most interesting part of the job. Compared to other production crops cannabis is just getting started in terms of potential and their will hopefully be alot more research to come. Bruce in my opinion is a national treasure and a huge benefit to anyone in this industry with skin in the game trying to grow and compete

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." 🌴🙏🌴

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?

[@justme-ud2vk]

this guy is truly brilliant. hes a light wizard.

[@BrianM-44041]

A negative temperature differential can slow stretch, letting night temps be equal to day or even slightly higher. Neat trick i learned years back.

[@Shepp6769]

Yep. It’s possible to slow the stretch down with lights out temps close to lights on temps (~ 2 degrees). Agree as well to start to slowly drop lights on temps on day 1, and be in the mid 70s by about week 3-4 till finish. I’ll go as far as shutting off the heat when there’s a coupla weeks to harvest, and only let lights on temps to 70-71 till harvest (lights off temps 66-67) Merry happy

[@BrianM-44041]

@Shepp6769 when possible to stop stretch your can even make dark temps even with light temps or higher.

[@JamesS.254]

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.

[@luchocontratodo]

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.

[@kmonty6188]

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.

[@anthonyromano8565]

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.

[@hughgodau]

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.

[@KannaKullektiv]

Very nice talk. Thanks for sharing this.

[@23lnp]

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

[@Memflix]

"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😃

[@TalksWithRyan]

I know low humidity eliminates all problems like mold and any other problems

[@juanbuddha4202]

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

[@zack9912000]

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

[@catsploitation]

Mould will still grow in low humidity because the bud density is humid inside, high temperatures and too much light will cause bud to rot, so can contamination from dust, or insects. For sure low humidity helps and airflow is crucial but that's not the whole story. Genetics make a big difference here too. Pure sativa and sativa dominant plants are must less likely to rot. Because sativa genetics originate from conditions often humid and hot. Indicas are effectively hash plants and most of those genetics originate in low humidity desert like places, Afghan, Lebanon etc. They typically grow dense to preserve moisture and rot easily when grown in wetter conditions.

7? what?

[@symphantic4552]

Bless this guy for using Celsius some times

[@Dopefoot]

The positive diff helps bring out colour though does it not?

[@JayDawg03]

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

[@ewreck944]

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

[@clyp0001]

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

[@patrickwilson9783]

No it's more complicated than that

[@natel9019]

High temps at night makes purple colors too. I rocked 500 lighter at 86 degrees at night. Purple colors everywhere.

[@lucaschraner]

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

[@JamesSmith-e9w]

I think so🤔

[@jorgehenriquepessoa2265]

It will trigger reproduction, would that mean that hermies come from a too cold environment at night? Because i might be having this problem.

[@justme-ud2vk]

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.

[@Reutzel507]

He is going off the data not your opinion. I know that’s a hard thing to understand

[@user-ve7hn2dh8h]

Its not air temperature that makes terpines evaporate tho, it's the temperature of the plant material.. What I'm saying is, if you grow with LEDs you need the higher temperatures to get the plants transpiration going.. With HPS, you're right, 75f or so is the right temp, since HPS has a shit ton of infrared light which doesn't heat up the ambient air but the leaves and buds

[@NTBS]

sorry bro i've seen grows in temps of 101 degrees out doors with great flowers and what bro? u back yard mechanic.

[@kmonty6188]

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.

[@Bockwursty]

It was legalised in Germany in April this year and suddenly we have a ton of experts trying to school you in the basics that they read and never experienced themselves. I had a long discussion with someone because I have more than 45% humidity in flowers. He was 100% sure it would get mouldy. I have been working with not only the same strain but the same flower for almost 3 years. I have never had a mouldy bud. But why should I know? I only had it in flower about 20 times.

[@Saturn-Matrix]

@kmonty6188 You're wrong about the statement saying "he's one of the only ones studying it for a long time." The Pgymys of Australia used Cannabis according to them since the dawn of time. That translates to over 12,000 years ago before the flood when there was no concept of time. Aka the purple dawn/ Saturn locked in the Dawn position / dawn of time. Even Aliester Crowley was doing rituals with cannabis in the 1930s on April 20th. The word "canna" is pre indo-eurpoean. Celopatria was said to smoke it for her migraines. Indians gave it to the Brittish colonizers. So just because you are not hip to the history and cultivation of cannabis doesn't mean everyone else is. You sound very naive putting your authority in academia when it is strewn the indoctrination of lies.

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.

[@MarcusRefusius]

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.

[@klayn1204]

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

[@MarcusRefusius]

@@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.

[@tinachung-gg2rq]

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.
