Welcome to Hydroponics Daily with Dr. Russell Sharp, where we explore the intriguing concept of day-night temperature differentials or DIF. Unearth the 1980s discovery by Dr. Royal Hines that revolutionized modern commercial growing. Understand how manipulating heat application at different times of the day can dramatically influence plant growth without the need for growth regulators.

Discover how a positive DIF leads to taller plants, ideal for crops like lettuce and cut flowers, while a negative DIF keeps plants from becoming leggy, making it suitable for ornamentals. Join us to further delve into the technological advances allowing growers to control DIF and achieve optimal growth, flower quality, and aesthetic appeal.
