Root & Growth Booster

Startbooster is a specially formulated organic root and growth stimulant. Startbooster is 100% organic with active organic ingredients that promote root system development and vegetative growth. A specific microbiomass supports root development. It stimulates the formation of root hairs, improves soil structure, and provides the plant with bioavailable nutrients during the growth phase.

Why use start boosters?

  • Powerful root and growth stimulator (more roots and faster plant growth)

  • Improved development of stems, root system and plant tissue (better vegetative growth)

  • Promotes population and strength of microorganisms

  • Improves the cell structure of the stem (up to 2× thicker)

Application of Startbooster

Use Startbooster as an additive to NPK fertilizers. On pre-fertilized soil, Startbooster can be used without additional growth fertilizer. Applying Startbooster can shorten the pre-growth phase.

Use Startbooster during the pre-growth phase and the first week of flowering. Use 2.5 ml per 10 L of water. Add Startbooster only after adding the NPK nutrients and measuring the EC.

Startbooster is a 100% organic product. Be careful when using it in drip irrigation systems—organic products increase the risk of clogging. Therefore, System-Clean should always be used together with Startbooster in such systems.

Start Booster Contains

  • Organic nitrogen chelated with L-amino acids

  • Microlife form biomass from controlled fermentation of selected strains (specific beneficial microorganisms)

  • Humic acids from the Leonardite layer

  • High-quality fulvic acids

How Startbooster Works

  • Organic nitrogen from L-amino acids promotes vegetative growth without risk of burns or overdose

  • L-amino acids promote growth, biostimulate and strengthen the bacterial population

  • Humic acids improve water retention capacity, condition the root environment and improve ion exchange

  • The microbial biomass decomposes nutrients and acts antagonistically against pathogens

Tips from successful gardeners

  • Use a dilution of 1:1000 to supply new clones (1 ml per 1 L of water)

  • When repotting, immerse the roots in a 1:100 solution (10 ml per 1 L of water)

  • Do not leave Startbooster in the storage container for longer than 2–3 days to avoid biofilm formation and blockage of the drip lines
