Type and Use

Bio Rhizothonic by Canna is an entirely organic root stimulant of plant origin. It can be used on all growing mediums.

Plant Benefits

  • It stimulates the root development, increases the amount of root hair and the root tips.
  • By stimulating the roots, it produces larger and more vigorous plants, with a greater capacity to absorb nutrients and, ultimately, more and better production of buds.
  • It also increases the plant's resistance to diseases and stress conditions.

Use and Dosage

  • Mix 2 to 4 ml of Bio Rhizotonic for every 1-liter of water, apply during watering until substantial root mass is achieved.
  • Canna Bio Rhizotonic can be used throughout the plant’s life cycle at a dose of 0.5ml per 1 liter of water until the final weeks when you'll only be using water.
  • When transplanting, it's advised to pre-water the substrate with Canna Bio Rhizotonic.

La Huerta's Opinion

Once mixed with water, do not store for more than 24 hours.

Bio Rhizotonic from Canna is a root formation stimulant, for optimal development of the cannabis plant, it should be used alongside a complete growth fertilizer. If you wish to continue with Canna’s natural and organic line, we recommend Bio Vega.
