The original OSA (Si(OH)₄) formula
Gen200 was launched in 2012 with the introduction of Control, the Original OSA (Si(OH)₄) Formula. Conceived for the indoor cultivation of flowers and fruit, the benefits of our proprietary orthosilicic acid recipe were quickly embraced by home growers as well. Gen200 Control supplies silicon as stabilised orthosilicic acid (Si(OH)₄), which plants take up directly. Silicon strengthens the cell walls, for firmer stems and leaves and better tolerance of heat, cold and drought.- Silicon: approx. 2.56% Si(OH)₄ (1.6% SiO₂ w/w)
- Dosage: 15 ml per 100 L of feeding water
- Yield per bottle: 1 L treats approx. 6,700 L of water
- Sizes: 100 ml · 250 ml · 500 ml · 1 L · 5 L
Enzymes for a clean, active root zone
Gen200 Enzyme breaks down dead material in the substrate, such as old root residues, so the root zone stays clean. The broken-down material is water soluble and easy to flush out.
- Dosage: 50 ml per 100 L of water (1:2000)
- Use: through the substrate, during growth and flowering
- Suitable for: soil, coco and hydroponics – all nutrient lines
- Sizes: 1 L · 5 L
Biological root stimulator for a strong start
Gen200 Grow Roots is a 100% organic fertiliser with naturally derived amino acids, developed to give plants a good start. Use it in the first weeks of the cycle to stimulate root and hair-root development – and longer if you like, because plants keep making new roots.
- Type: 100% organic, based on naturally derived amino acids
- Dosage: 100 ml per 100 L of water (1:1000)
- Use: through the substrate, with every watering
- Suitable for: all substrates and watering systems – all nutrient lines
- Sizes: 250 ml · 500 ml · 1 L · 5 L
pH down for your feeding water
Gen200 pH- lowers the pH of the feeding water to the ideal range for nutrient uptake. It is based on food-grade phosphoric acid and can be used with every nutrient line.
- Active ingredient: 59% phosphoric acid (H₃PO₄), food grade
- Use: add drop by drop as the last step, until the target pH is reached
- Suitable for: soil, coco and hydroponics
- Sizes: 1 L · 5 L
