Humidity in Flower..Myth or Fact?
-
Is the information we've received about humidity and its effect on flowering plants incorrect?
I am currently grappling with the challenge of managing an indoor summer crop. Despite my best efforts to regulate the humidity in my 4x8 space filled with blooming plants, I'm struggling to keep it under control.
Despite being in the flowering stage for several weeks, humidity levels have spiked to 78%, even with considerable airflow around the plants. I can't seem to lower the humidity, which isn't considered ideal for flowering.
Apart from the threat of mildew or bud rot, are there potential advantages to high humidity during the flowering stage? I've come across discussions suggesting that a balance of 70% humidity and 70° temperature might be beneficial, even though it deviates from conventional wisdom. I'm open to learning more about this.
In the past, I've cultivated plants in a greenhouse with extreme temperatures and humidity levels. All I could do was maintain air circulation and hope for the best. While I did lose a small amount to rot, the majority of the crop thrived. However, I've never experienced high humidity indoors during the flowering stage before.
Throughout the flowering stage, the humidity has consistently stayed above 60%, day and night. So far, I haven't encountered any issues, and I inspect the plants daily.
In fact, one particular plant has finished flowering and is ready for harvest. The plant seems to have tolerated the humidity well, showing no signs of mildew or bud rot.
I'd appreciate your thoughts on this. Although conventional wisdom advocates for lower humidity levels, is this merely a preventive measure, or could cannabis potentially benefit from higher humidity during its flowering stage?

The main point to consider here is whether you are working in an enclosed tent. If so, purchasing a dehumidifier could be a sensible decision for the summer period. This applies even if the tent is situated in an air-conditioned room.

This year, I made a purchase that I'm extremely satisfied with. I believe the issue was excess moisture. Strangely, I went for a model with an 80-pint capacity, but it seems to be currently out of stock.

This year, I made a purchase that I'm extremely satisfied with. The dampness in that area was probably just too much. Strangely enough, I obtained a unit with an 80-pint capacity, which is currently not on the market.

I've never experienced bud rot or mould. I don't even monitor my relative humidity now. Just maintain good ventilation, and you shouldn't encounter any problems.

The main question that might not be immediately apparent is whether a dehumidifier would be a wise purchase for use during the summer season if you are functioning within a closed tent. This is merely a tent located in an air-conditioned room.

The person stated that they've never experienced bud rot or mould, not even bothering to monitor their rh anymore, as long as there's good air circulation. They had an encounter with bud rot once in an outdoor setting. Normally, it's not a major concern for them, but they find rising rates near 80% daunting, especially with a 10-week old plant. They expressed curiosity about other people's experiences. They wondered whether maintaining 40-50% rh is merely a preventive measure or if high rh during the blooming period can offer some advantages as well.

The primary protection strategy is ensuring good air circulation; place several fans under the shelter and think about regular leaf removal to reduce possible harm. Understood, making sure every aspect is taken care of. I'm waiting for autumn.

A dehumidifier releases warm air through its outlet. If you create a shield for this and direct the exhaust outside your room, it's effective. Without this, it could increase the temperature in your cultivation space. I channeled mine upwards via a chimney.

The speaker is asking for more information on a particular subject. They cultivate plants inside and have occasionally experienced bud rot despite maintaining continuous air circulation. They aim to maintain the relative humidity at about 50%, but it can sometimes increase to 70%. They also note that the thickest buds are the most prone to this issue.

Have we been misled by our elders about the impact of humidity on flowering plants?
I'm barely managing this indoor summer growth. I have a 4x8 area filled with budding flora that's proving difficult to regulate in terms of humidity.
The plants have been flowering intensely for weeks, and I've seen humidity levels rise to 78%. Despite ample airflow around the plants, I'm struggling to reduce the humidity.
It's not the best conditions for flowering according to conventional wisdom, yet the plants seem to be growing normally.
Apart from the potential for powdery mildew or bud rot, could there be any advantages to having higher humidity during flowering? I've come across a few discussions where people have found an optimal balance at 70% humidity and 70°. It's not the usual practice, but I'm open to learning more.
Previously, I've managed plants in a greenhouse with extremely high temperatures and humidity. All I could do was ensure good ventilation and hope for the best. They thrived, and I only lost a small amount to rot, but the majority was perfectly fine. However, I've never had to deal with high humidity indoors during flowering.
Throughout the entire flowering period, my humidity has consistently been over 60%, both day and night. I haven't noticed any issues, and trust me, I check daily.
In fact, the large C99 plant has fully flowered and is set to be harvested today. It has managed to withstand the humidity without any signs of powdery mildew or bud rot.
I'm interested in hearing your thoughts on this. Yes, I know the common belief is to maintain lower levels, but is this purely a preventative measure? Could cannabis potentially benefit from higher humidity during flowering?

Could a compact version function effectively inside the tent? The space isn't damp in the slightest. Everything is confined within that tent.

The original post implies that the writer doesn't usually worry about bud rot or mould due to good airflow. They've had bud rot once when growing outdoors, and find high humidity levels (around 80%) alarming, especially for plants that are already 10 weeks in. They're interested in understanding other people's experiences and are asking if the recommended 40-50% relative humidity is merely a preventative measure, or if there could be some benefits to high humidity levels during the flowering stage.

The paraphrased text could be:
There appears to be some research suggesting that cannabis contains more cannabinoids when grown in dry air. This conclusion was supported by an old study that examined cannabis grown near the coast and in hilly areas. Additionally, high humidity often leads to mold, which is a risk many aren't willing to take. Hopefully, the cooler, drier autumn weather will arrive soon to alleviate some of these issues. Up until now, luck has been on my side, even though managing a full growing tent has been challenging.

I've never experienced any issues with bud rot or mould. I've stopped monitoring my relative humidity. Maintaining proper ventilation is key and everything should be alright.

The point raised highlights that it's worth considering the purchase of a dehumidifier for use during summer if you're working within a closed-off tent. It's simply a tent situated in an air-conditioned room.

MickFoster's statement:
This isn't a fallacy. I'm eager to learn more about this subject.

The assertion is not a fabrication.
-
Could a compact one function properly if situated within the tent? The space isn't damp in the slightest. Everything is confined to the tent.

Our most effective protection is air circulation; consider placing several fans under the canopy and routinely removing leaves to reduce potential harm.
