How Can Climate Affect Your Weed Plants

The climate in your growing environment – from the temperature to the humidity – can often change, influencing your plants. While it is common for there to be high humidity because marijuana plants release moisture, you don’t want things to get out of hand.

When your plants display evidence of stress, especially on the parts of the leaves closest to the light/heat, this indicates a temperature problem. You may even notice that the leaves are yellow with brown discoloration or even burn marks.

Additionally, the amount of water your plants evaporate is based on the space’s humidity. When the humidity is too low, your plants will be quicker to take in nutrients and water. They will also evaporate at a greater rate. Now, if it is absorbing too much, the plant will close its stomata so that it retains some water and doesn’t get dehydrated. Incorrect humidity will slow down plant growth.

Dehumidifiers are excellent for controlling the humidity in closed environments. Dehumidifiers have cold tubing that condense air moisture and reduces the humidity. As far as heat goes, it may actually be harmful because the machine gives off a bit of heat. This can cause your grow space to get too hot. You can keep this from happening by adding air vent tubing to the dehumidifier’s exhaust area. By doing this, the heat is transferred to a different area and won’t cause the room temperature to rise.

Ventilation can reduce the heat in your grow space, but you can also use an air conditioner. Some people even try installing an air cooler prior to when the plants reach the flowering stage. This will cause the water to evaporate, which reduces the room temperature. Air coolers will not cause the humidity to be imbalanced. They will instead help your plants thrive during the early stages of growth. Once your plant is in the flowering phase, it is time to stop using air coolers because they increase the moisture levels too much.

Another way to tone down the heat is to get rid of any unnecessary equipment in the room that creates heat, such as light ballasts and large pumps.

For plants grown in hydroponic systems, you will only need to adjust the temperature of the plant instead of trying to fix the room temperature. You do this by reducing the temperature of the growing water. Aquarium water coolers are a great way to automatically ensure the water stays cool. When the water happens to be around 80 degrees, adjust the water temperature to be closer to 60 degrees Fahrenheit.

The best way to keep the temperature under control is to take the necessary precautions. One way is with lighting. There are actually lights you can buy that are water or air-cooled. These use tubing to divert all of the heat created by the lamps so that an equal measure of heat is formed and doesn’t have a negative influence on your space.

  • Plant growth slows down
  • Edges of leaves are curled up
  • Brown or burn spots on leaves
  • Leaves closest to the light or heat is affected
  • Leaves turn yellow

If, for any reason, you have major fluctuations in the temperature between day and night, try using the opposite light order. Let the lights stay on throughout the night, which causes the cooler night to be warmer for your plants. During the daytime, turn the lights off, which makes the temperature cooler on hot afternoons. This way, you have the optimum temperature at all times in your grow room.
