    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." 🌴🙏🌴

    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!

    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

    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.

    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

  • @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

    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

    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 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.

    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.

    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.

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.
