Damn cold ass weather sucks.

[growmie]

Well brought in my Ayahuasca Purple after work. My Mimosa looks pretty happy still. Crazy shit. Tough ass plant. I'm going to cover it tonight and probably bring it in tomorrow. Can't decide if I should bring it or my Tropicana Banana first.

Yea get um to at least 60F ASAP. Some people think the THC doesn't get affected but it does. The trichomes suffer the same fate upon prolonged exposure of frost, etc. Like others mentioned, you're better off planting earlier or getting FF/auto's. or getting a greenhouse with a heater during these cold days.

Not good. Blankets...

Frost damage in cannabis plants can be identified by several symptoms:

1. Discoloration: Leaves may turn black or dark brown, indicating cellular damage.
2. Wilting: Frost-damaged plants often exhibit wilting or drooping leaves and stems.
3. Necrosis: Dead tissue may appear on leaves and buds, leading to decay and mold issues.

Frost can cause the water within plant cells to freeze. As water expands when it turns into ice, it can rupture cell walls, leading to cellular damage or death. Cold temperatures slow down the metabolic processes in plants, including photosynthesis. This can hinder growth and reduce the plant’s ability to produce energy. Frost can also affect the soil, making it harder for roots to absorb water and nutrients. This can lead to deficiencies and overall poor plant health.

The trichomes are oil based, thus lower freezing temperature. They exist to protect the leaf and plant cells from damage. If danger(aka freezing) is incoming, a "smart" plant would increase trichomes(force field). More THC. Just my thought process. I still have half a plant outside ready for the next frost as an experiment.

I saw some guys on YouTube growing outdoors in Minnesota That thought just that. they wanted a frost! I think Imazudae Posted it. He grew in Minnesota and I wonder what happened to him! He was pretty helpful!

Are you talking about watering with ice-cold water. Presumably, the idea is to shock the plant's root system and cause enough stress to promote trichome production without ruining your harvest. You'll want to give your cannabis plants an ice bath as close to harvest as possible.

Trichomes can protect the plant from a large range of detriments, such as UV light, insects, transpiration, and freeze intolerance.

Freezing the cannabis plant before preparing hash or any other extracts will help make the trichomes, which are glands that secrete resin that contains THC, CBD, and other cannabinoids, more brittle and hence easier to separate.

Freezing causes the trichomes to become more brittle, which makes it easier for them to break off when the buds are handled. When the flower is smoked or vaporized in this manner, the psychoactive effects of the plant may be diminished.

Freezing marijuana is usually not recommended unless you practice great care in its storage. Extremely cold temperatures won't slow down the natural degradation of cannabinoids and terpenes like you’d think. Freezing marijuana can actually speed up the degradation process.

When exposed to freezing temperatures for a long time, the plant's trichomes will freeze and become more brittle, and more vulnerable to damage, falling off with the slightest disturbance. The only instance freezing cannabis is recommended is when making ice water hash or live resin frozen cannabis plants.

BUT.... AS for frost, trichomes rot and die at temps below 50F.

Frost can significantly impact the cannabinoid and terpene profiles of cannabis plants. Low temperatures can alter the synthesis and accumulation of cannabinoids, potentially affecting the potency and therapeutic properties of the harvested buds. Similarly, the exposure to frost can modify the terpene composition, influencing the aroma and flavor characteristics of the final product.

The alterations in terpene profiles caused by frost can lead to changes in the aroma and flavor of cannabis. The delicate balance of terpenes responsible for the distinctive scent and taste of different strains can be disrupted, resulting in less pronounced or altered sensory experiences for consumers. Furthermore, the impact of frost on cannabinoid levels can affect the overall potency and effects of cannabis products.

Cannabis plants are generally sensitive to freezing temperatures, with most strains experiencing significant damage below 28°F (-2°C). However, some cold-resistant strains can tolerate slightly lower temperatures.

Left: normal temperature trichomes
Right: frosted trichomes after defrost.

See the difference. Frost isn't good for live plants.

If you harvest a normal plant and then want to freeze buds during storage is another story. Not the same.

I've never understood why some think it's good to grow to frost if not a freeze. Everytime I've got caught out by a frost or freeze it's ruined the plants.

Some cold temps aren't bad and actually can be good for the plants. But anytime temps hit 28F or under its not good.

 

[Phreakshow]

Well it's warmed up a whole lot to 35 last night. Daytime temps high 40s low 50s. Covered my Mimosa last night so she should be doing well this morning. Going to take my Tropicana Banana 1st as I can't cover it. My Mimosa should be fine.
Also I know nothing obviously doesn't it need to be consecutive times of cold and frost to cause damage you are describing?

This thread is interesting to me. Some people swear by letting their plants get some frost. Others don't believe in it. The photo of the trichomes after being frozen is pretty telling to me.

This forum proves that there are many ways to grow this plant, if nothing else.

Thanks for everyone's input.

@Phreakshow
How's your plant doing that looked droopy after the frost?

My Ayahuasca Purple and Tropicana Banana handled it pretty well. My Mimosa looks kind of sad though. Its definitely time to come down.

I just would not leave plants in freezing temps. more than 2 days cause as it thaws and water stays inside those big as cola buds or buds it does not dry out it holds the moisture traps it and as air heats up maybe to 50f it creates a perfect mould home to grow. Do the experiment but don't push your luck you have lovely plants count your blessings and get them hung in a good warm dry area.

 

[Phreakshow]

My drying room is 70 degrees with 47% humidity

 

[Oldchucky]

Close enough for government work! Be nice if it was a little cooler, but we take what we can get!

I could open a window some.

 

[Oldchucky]

Up to you! You’re the grower! I know about the best I can do on humidity is about 45! But I can get 60° but I think they’re still dry a little too fast! I’m happy if I can get six or seven days out of them! Just have to watch and learn! So far, you’ve been making the calls, right!

Your a good man Oldchucky. You always make me feel good about what I'm doing.

 

[growmie]

Ur good. 50% humidity and around 70°F for at least 3 days, then lower temp as needed. RH should be 60-65% during cure. Looking good.

Are you thinking about trimming the buds? Keep in mind that the more stems there are, the longer it will take to dry. If your plant is “stringy”, this means that there is still a lot of moisture inside. Even if the buds feel too dry, provided the stems are still bendy this means that there is still too much moisture inside which can end up outside the buds when you cure them. This is the ideal time to pull the buds down and place them in a jar.

When you remove the buds from the stems, it’s important to jar the buds immediately when the outsides are dry to touch; right before the buds have dried completely since there will no longer be stems to accumulate water. When the outside of the buds are dry to the touch, this will reduce the chances of any mold growing, since it tends to grow outside when buds are damp.

Well it's begun. Night temps have dropped considerably. Day before yesterday we had a high winds that broke a couple branches and the temp dropped to 29 degrees. 1 of my plants had some leaves die from the cold. Other 2 were hating it but looked ok. Last night it was 34. Haven't been out to look at them yet. Not sure what to do. Nights won't get much warmer. My plants never finish. I have never had a plant harvested because it has ambered enough in my 4 years growing. None of them have any amber at this point still. Will probably just pull them. I dont anticipate much if any change at all going forward. My grow season is to short and my garden not sunny enough. Disappointed.

That's the realities of outdoor
