4.) Watch Your Humidity - High Humidity Helps Young Plants, While Low Humidity Is Crucial To Prevent Mold During Flowering/Budding
Humidity is a term used to describe the amount of water vapor present in the air at any given place.
It is common for new growers to not pay attention to humidity at all, and this causes many otherwise unexpected and unexplainable problems.
Young cannabis plants enjoy having the humidity in the 40-70% range.
In fact, it's common for young cannabis plants to show false signs of nutrient deficiencies when the humidity of the grow area drops below the optimal range, especially when things get really dry.
In the flowering stage, humidity should be kept below 45% to prevent mold.
When humidity gets too high in a grow room, the plant pulls excess water in through the leaves which increases your chances for mold.
Younger plants are more resilient, but high humidity is especially dangerous in the flowering stage when the insides of the buds can grow mold and look fine from the outside.
What to do:Get a humidity monitor, and start paying attention to the humidity of your grow room.
You can then use a humidifier and/or a dehumidifier to keep the humidity in the optimal range.
A humidifier adds moisture to the air while a dehumidifier takes moisture out.
Controlling your grow room humidity is one of the tricks that separates the expert growers from the beginners.
You can get some pretty fancy humidity gauges for under $10 to place in your grow room, and (de)humidifiers to change the humidity are commonly found at department stores, hardware stores, or most stores that sell home appliances.
Is there any reason your running your humidiy so low in the veg stage.

- Ideally, your grow room will have a humidity of 60% during the vegetative stage, and should be lowered to around 45% at the beginning of the flowering stage.
- As your buds fatten up, it is beneficial to continue to drop the humidity of the grow area, if you can.
- During the last 2-3 weeks before harvest, I use a dehumidifier to dramatically drop the humidity of my grow area as low as I can, which prevents bud rot during the last few weeks.
- As an added bonus, dropping the humidity this way during the last few weeks of your plant's life increases trichome production, so you harvest sparkly, crystal-covered extra-POTENT buds.
Is there any reason your running your humidiy so low in the veg stage.
