Plant productivity can slows- An example of  productivity being effected by temperature would be slowed plant growth in colder temperatures. In temperatures that are too warm, fruits may not set.

The amount of pests can gro- Pests prefer a warmer climate. Keeping your grow room too warm could be making it a suitable environment for pests to infest.

Plant size can be effected- Temperature also has an effect on the size of your plant. In nature plants experience a temperature change from day time to night time. This actually assists with the plant’s growth. It’s recommend to drop the temperature 10-15 degrees during the lights off period.

You can use this to your advantage to manipulate how big your plants get overall. Providing a temperature variation of less the 5 degree will cause plants to produce less space between nodules, meaning plants will grow smaller and more compact.

Crops are usually placed in 2 categories when it comes to temperature, cool weather and warm weather. As with other aspects of the garden you should match what the plant would experience in its natural habitat, nature.

I usually keep my warm weather crops somewhere between 75-85 degrees.
