Is anybody experimenting with temps and trichs?

[I Care]

Here I go again asking questions with titles. I’m wondering because of my own personal experience after some abuse during the curing process.

Had some buds that I expected to turn color, but I started to witness the potency going down and the bulking up had stopped for about two weeks. Decided it was time even though they really hadn’t really matured to the level I was waiting for.

After a long scooter ride I left my jar in the trunk and it was hot in there. Finally I had some amber and a light green frosty jar finally appeared fully mature. I’m kinda thinking that is what was missing while waiting for color. That I was missing the target on temps and humidity at the end of flower. Feel a little like I missed the actual days of maturity waiting on them to turn and maybe I was just not giving enough warmth.


So back to the question, anybody know if temp and humidity is the right way to encourage the maturity of trichs at the end of flowering?

I want to say it’s 82F and 70% humidity, although thats the threshold of totally screwed. Risky in case of any fluctuations.

What do you think/know?

 

[Douglas.Curtis]

Personally... I veg longer for a larger plant, then flower around 70F(MAX!)/20-30%RH. Cool and dry consistently creates the most trichome dense, terpene/cannabinoid rich flowers for me.

Color only shows on strains known for color(Edit: Read your question wrong. My apologies. I've never noticed amber differences through temp/rh manipulation, only extreme quality differences). The other main difference is the yield is lower, hence the longer veg time.

 

[Douglas.Curtis]

Read the last 20+ years of forum postings and articles on cannabis. You'll see, time and time again, growers noting how they failed during the winter grow to keep temps and RH up... but they produced the best quality so far.

Cool and dry for the win, with an added bonus of massively low mold issues. (3x/minute air exchange)

I just thought about getting another duct fan. Warmer and more humid than comfortable inside and translates into the night rig the way tents compound things. Well I woke up this afternoon and was brutal in my place. No drastic changes in the trichs.

my space is about 25cubic so I’ll just get whatever cheap-o catches my eye when i catch the coin. def high heat ain’t working indoor for anything but fusarium.


going to try the scooter trunk trick again not to do it with all the puffage this time so I can do a side by side

Temps in the 60's with low teen humidity is what I like personally.
Hotter and moister makes a bit more production wise but doesn't seem quite as good as the winter grows.
Time effects the maturity degradation is what everything else does?

I hope I'm wrong but it looks like the beginning of powdery mildew in the first pic.

if so try some live milk water... after you go bone dry for a spell
sulfur is especially useful yeah anything over 80F isnt good
and 40% humidity is hard to achieve in coastal areas even running appliances

Like dogzer said winter is best for sensitive strains, thats why this skunk waits on winter

Cold air holds less moisture than hot air, drought stress promotes terpene production and sugar feeds

Indoor mold - Wikipedia

Prevention​

Mold growth can be inhibited by keeping surfaces at conditions that are further from condensation, with relative humidity levels below 75%. This usually translates to a relative humidity of indoor air below 60%, in agreement with the guidelines for thermal comfort that recommend a relative humidity between 40 - 60 %. Moisture buildup in buildings may arise from water penetrating areas of the building envelope or fabric, from plumbing leaks, rainwater or groundwater penetration, or from condensation due to improper ventilation, insufficient heating or poor thermal quality of the building envelope.[12] Even something as simple as drying clothes indoors on radiators can increase the risk of mold growth, if the humidity produced is not able to escape the building via ventilation.[13]

only thing know to do is to remove what I can see and adjust fans so whole plant gets the shimmy going on. Recently tried zapping PM with 1100w of incandescent, 120 degrees and a dehumidifier on blast for 48hrs with success. Never tried live milk. NO more water to this mess this week and wont flood again.

That’s a nice looking skunk mom, don't know If I’ve ever had skunk weed. I bet that’s a treat for puffing on while preparing the garden in spring. not yet sure what I’m going to throw in the rig for winter

Thats what I set my A/C to when I was in the southeast. It was set on 60 and that meant running 24/7. 5x5 had an exhaust and the temp/hum probe for my monitor hung directly below the fixture would run a constant 82, until one day I left the run off in there because I was in a hurry and closed the door. humidity compounded into temperature rise. Had to pull out and carefully inspect every bud, every day, until the finish.

You got your temps in the tent up to 120 to try and kill pm? Wow that's a new one.

70% RH near the end of flower is a disaster waiting to happen. Growing cannabis the only time RH is that high for me is the beginning of veg.

There are quite a few threads covering the basics on this fine site. Check them out. A great grower masters the basics then repeats.

Wettable Sulphur for the pm

I succeeded, a box dried layered between paper towels was interestingly small loss at deepest center of the box. so I guess it worked well.

I read that fusarium dies above 110 or somewhere around there and I was deep into flower. come to think of it I had 5 weeks gmo flower that had yellow dry sift (7minute) falling off of it.

 

[I Care]

Hey guys, so here’s an update.

Ya, so an unconrotlled slide of heat into the house on those hot days really made a disaster happen inside.

it’s pretty cool in the evening so no more uncontrolled scooter trunk heat testing 2.0 has been done yet.

I’m going to go with the experienced growers on this one and agree that cooler temps, humidity control and time is the winningest formula. Theres nothing that beats comfort for these plants, for them to do the thing. Light watering, cool temps, low humidity and wait patiently with the magnifier.

 

[PlastikeRubba]

My best quality is over 90°

I guess this falls under the woke liberal "weed is subjective" narrative of the past decade. What's next, drag queens reading children stories? Weed was not subjective until legalization began.. Everyone agreed on quality until quality went to shit. And the Doterra narrative showed up. And the forbidden keywords related to medicinal properties of Cannabis.. Odd...

Read the last 20+ years of forum postings and articles on cannabis. You'll see, time and time again, growers noting how they failed during the winter grow to keep temps and RH up... but they produced the best quality so far.

Looks like the "strains" everyone wants might not even be the same species as the "strains" everyone grows?



"with an added bonus of massively low mood issues"

Mold only grows on dead things. Ask a biologist.

The clones of diesel I grew took a long time but it was the top of the plants that finished out amber. the other sour diesel that was being grown wasn’t quite as full profile as the one I waited on. It was under HPS where that temp remained 82 constant with the exception of one day. I was a little dissatisfied cause I knew that it was root bounded after the unexpected 90 days of darkness until it turned, but everyone else was impressed that I grew out a sour diesel that was better than the rest. I just knew it could have been even better with smaller plants and larger pots.

 

[Douglas.Curtis]

The only time I find 24hrs or more to be 'beneficial' before harvest is when my environment is wrong.

When you see a big change in your plants with only 24hrs of dark, I would bet almost every time the plants are simply looking relieved at the lack of stress for a moment.

 

[I Care]

I did a molasses flush with dry back into 48h dark on that same biocanna sour run. Possibly equalized moisture and dense up the buds for some extra potency before chopped.


Id be interested to try this, minus the flush and dry back. With that same full time air conditioned environment and a stable and healthy few plants again.

Wettable Sulphur for the pm

finally picked up some
do you have any special instructions or just follow the mf recommendation?

experiment of heating curing buds in motor vehicle storage compartment is coming soon

 

[Lester Beans]

Follow the directions. I haven't used that brand but it looks good. Use a proper mist sprayer. Spray before lights off. Spray everything, tent, pots, media, fans filters everything.
