<![CDATA[Humidity in Flower..Myth or Fact?]]>Have we been misled by our elders about the role of humidity in the growth of flowers?

I'm barely managing to navigate this indoor summer growth. My 4x8 space is filled with flowering plants and I'm struggling to maintain the right humidity levels.

I've been in the thick of the flowering stage for several weeks now, with humidity levels peaking at 78%. Despite sufficient airflow around the plants, I'm finding it hard to reduce the humidity.

This environment is not usually considered ideal for flowering, but the plants seem to be developing normally.

Apart from the potential threat of powdery mildew or bud rot, are there any advantages to elevated humidity during the flowering stage? I've come across a few discussions where a humidity level of 70% and a temperature of 70° is considered ideal. This deviates from the norm, but I'm receptive to differing viewpoints.

Previously, I've had experience growing in a greenhouse with extremely high temperatures and humidity levels. All I could do was ensure regular air circulation and hope for the best. Most of the plants thrived, with only a small portion succumbing to rot. However, I've never encountered high humidity indoors during the flowering stage.

Throughout the entire flowering phase, my humidity levels have consistently remained above 60% both day and night. So far, I haven't noticed any issues and I make it a point to check regularly.

In fact, the largest plant has finished its flowering stage and is ready for harvest today. It seems to have handled the humidity levels quite well with no signs of powdery mildew or bud rot.

I'd appreciate any insights on this. I'm aware that most literature suggests lower humidity levels, but is this merely a preventative measure or can the cannabis plant actually benefit from higher humidity during the flowering stage?

Efforts are made to keep the relative humidity around 50%, but it occasionally reaches up to 70%. Dense buds are particularly prone to this issue. There's a common concern about the risks of high humidity when flowering, but one wonders if there could be any advantages to navigating this precarious situation.

I recall one such study that examined cannabis growing near the coast and in hilly regions. It's an old study, though. Additionally, it's worth noting that higher humidity levels can lead to mold, which is something I'd prefer to avoid.

Creating a cover for it and ensuring it vents outside your room can make it function effectively. Otherwise, it could increase the temperature in your cultivation space. I directed my unit's exhaust up through a chimney.

I don't even monitor my relative humidity anymore. As long as you maintain proper ventilation, everything should be alright.

The humidity level is generally kept around 50%, but can occasionally rise to 70%. It's noted that the densest buds tend to be the most vulnerable. The text also talks about the common concern of increased humidity during the flowering stage and questions any potential advantages of navigating this risky situation.

One such study observed cannabis plants near the coast and up in the hills. Furthermore, it's important to note that higher levels of humidity can lead to mould, which is something to avoid.

Even with adequate air circulation and relative humidity of 40 percent, I've encountered early stages of bud rot. This occurs when the buds are very large and tightly packed, preventing air from penetrating them. Therefore, the type of plant you're cultivating and the size of its buds are crucial factors to consider. This is just my perspective.

I'm planning to harvest one of my larger plants tonight, which might alleviate some issues. The recent season has been a lesson in adaptability. In the next season, I'm considering reducing the number of plants for better management.

There are five more plants transitioning into mid-bloom right now. I'm optimistic that September will bring drier conditions.

Is there any advantage in treading that risky path? It appears there are no visible benefits.

They mention a past encounter with bud rot that occurred outside, expressing a little concern over high humidity levels when dealing with a mature plant. They are interested in understanding if there is any advantage to having high relative humidity during the flowering stage, or if the recommended 40-50% level is just a precaution to avoid potential issues.

I encountered the onset of bud rot despite having adequate ventilation and a relative humidity of 40 percent. This was because the buds were as large as a soda can and incredibly compact, preventing air from penetrating them. Therefore, the variety of strain you're cultivating and the size of the buds are crucial factors. This is just my viewpoint.

I experienced the onset of flower rot despite adequate ventilation and 40 percent relative humidity. This was because the flower clusters were as big as a soda can and extremely compact, preventing air from penetrating. Thus, the type of plant you're cultivating and the size of its flower clusters play a crucial role, in my view.

I'm planning to harvest a large plant tonight. Removing at least one plant might slightly improve the situation. This summer has been a period of learning. Next summer, I intend to try cultivating fewer plants to see if that works better.

There are 5 other plants transitioning into the blooming phase. I'm hopeful that September will bring drier conditions.

They aim for a relative humidity of around 50%, but it can sometimes go as high as 70%. They observe that very dense buds are particularly prone to this issue. They also express a common concern among those who grow flowers about the risks associated with high humidity. However, they ponder on the potential advantages of treading this uncertain path.

I recall a specific study comparing cannabis grown near the coast and in hilly regions. It's a vintage piece of research. Furthermore, high humidity levels can lead to mold growth, a risk I'm not willing to take.

An old study by a researcher who observed the cannabis near the coastline and hilltops is referenced. The text also addresses the issue of humidity causing mould, expressing a desire to avoid that issue. The person speaking hopes for the arrival of autumn and mentions some challenges they are facing with a full tent.

I cultivate plants indoors and sometimes experience bud rot despite maintaining a steady air circulation. I aim to keep the humidity around 50%, but it often increases to 70%. It seems that the densest buds are the most vulnerable.

There appear to be several studies suggesting that the dryer the environment, the higher the cannabinoid content in cannabis. An ancient study even examined cannabis growing near the coast and in hilly areas. Moreover, excessive humidity can lead to mould which poses a threat. The hope is for the cooler autumn season to set in soon to mitigate these challenges, especially when dealing with a fully grown crop.
