Cytoplex® HMS


Product Overview

Cytoplex® HMS, a plant growth regulator, consists of EPA-registered sea plant extracts in addition to gibberellic acid and indole-3-butyric acid. This product enhances root development, lateral branching, flowering, and fruit development of key crops. Use Cytoplex HMS to accelerate the plant’s vegetative start under cool soil conditions. Even under stress, Cytoplex HMS promotes rapid emergence and helps maintain early season growth.

  • Water soluble


  • Helps maintain early season growth and Improves overall crop production
  • Reduces plant stress
  • Stimulates a cytokinin plant effect
  • Leads to rapid seed germination
  • Promotes early season vigor

How does it work?

Plant Growth Regulators (PGRs), like Cytoplex HMS, stimulate the plant’s vegetative and reproductive stages to enhance crop yield and quality. Cytoplex HMS is a balanced, multi-functional PGR powered by natural Zeatin purines unlike other multi-hormonal PGR products. Zeatin, Auxins, and Gibberellin work together to stimulate “new” cell growth and cell expansion. Auxins direct movement of food to these new cells and with a partner (Cytokinin), promotes cell growth. Gibberellin regulates movement of nutrients into the cell for cell expansion. Cytoplex HMS is ideal for use when trying to get plants off to a faster vegetative start under cool soil conditions. The balanced Cytokinin/Auxin ratio in Cytoplex HMS enhances root development.
