Gen200 Control, The first, the best, the original OSA
Gen200 was launched in 2012 with the introduction of Control, the Original OSA (SiOH4) Formula.
Conceived for the indoor cultivation of flowers and fruit, the benefits of our proprietary ortho silicic acid recipe were quickly embraced by home growers as well.


A bio-mix of natural micro-elements supplemented with 100% bio-available ortho silicic acid.
GEN200 Control is a proprietary biomix of natural micro-elements supplemented with ortho silicic acid. GEN200 Control ensures the regulation of the growth of the plants and their natural defence system. This ensures that the plants are more resistant against diseases and distresses such as extreme heat and cold. Your plants will root faster, develop stronger stems and leaves, which will result in firmer plants and bigger yields. GEN200 Control can be used on all kinds of soil and with all kinds of nutrition.

Farmers can save money by using GEN200 Control, because of the decreased importance of the use of insecticides, fungicides and pesticides. Higher yield and better quality of products with increased shelf life due to better water
retention in fruits and vegetables is another advantage.


Application Instructions
-Always add GEN200 Control to the feeding water, before adding other nutrients.
-Add 15 ml per 100 liter of feeding water with every watering session.
-If used as a foliar spray, apply 1 ml per liter of water.
-Keep out of reach of children.
-Keep below room temperature.




Boost your plants defence with a Control foliar spray
Gen200 Control can be easily mixed and applied as a foliar spray, ensuring that plants receive consistent and uniform coverage without the complications of soil amendments.

Use as foliar spray: 1 ml per L (1-2 per week)



Control the height of your plants
Effective in controlling the vertical growth of plants. Feeding the plants increased doses of GEN200 Control, they will get elevated levels of silicon in their system. The physical effects this silicon has on the cell walls and outer layers of the plant prevent the plant tissue from stretching. The result is shorter plants, with decreased internode length and a multitude of side branches.

To slow vertical growth (stretch). Add higher dilution of: 3 ml per 10 L in nutrient reservoir.
