  • Always use System-Clean when using Topbooster in drip irrigation systems

Topbooster's active ingredients are selected on basis of quality and plant availability. Therefore Topbooster has a direct powerful and visible effect on the flowering process.

Application and dosage
Topbooster contains a synergetic cocktail of active ingredients that stimulate the complete flowering process. We therefore advise to use Topbooster almost during the complete flowering phase. Use Topbooster as an additive next to a base NPK fertilizer. Use 20ml per 100 litres (1:5000) from the second week of flowering until the last week.

Topbooster is an 100% organic product. Be careful with the use of organic product in drip irrigation systems. In such systems, organic product increase the risk of blockages. Therefore, always use System-Clean when using Topbooster in drip irrigation systems.
