Safer®  Hydro FAQ: What Are Ideal Temps For Growing Plants?

In this sense, plants and people have a lot in common.

The perfect daytime (lights on) temperature is 70 to 75 degrees F, comfortably warm but not hot.

At night (lights off), plants fare better when the temperature drops to 65 degrees F.

When conditions are too warm, plants are vulnerable to heat stress, which can slow growth and even damage plants, and fungi are more likely to prosper. Temperatures at or below 60 degrees F can lead to nutrient deficiencies and slow growth. Consistent ventilation with fresh air whenever possible is the best way to keep temperatures within your plants' comfort zone.
