Abscisic acid (ABA)
Marijuana Horticulture
by Jorge Cervantes
Abscisic acid is a naturally occurring hormone that assists plants in adapting to environmental stresses like drought or cold temperatures. During winter, ABA converts leaves into stiff bud scales which cover the meristem, protecting it from cold damage or dehydration. In case of an early spring, ABA will also prolong dormancy, preventing premature sprouts which could be damaged by frost.
Used in the garden, ABA may help plants resist drought and unreasonable conditions and improve productivity, strength, and performance.
