Gen200 Control, the first, the best, the original OSA

Gen200 launched in 2012 with the introduction of Control, the Original OSA (SiOH4) formula.

Designed for indoor cultivation of flowers and fruit, the benefits of our patented orthosilicic acid recipe were quickly embraced by home growers.

GEN200 Control is a patented bio‐mix of natural microelements supplemented with 100% bioavailable orthosilicic acid (SiOH4).

GEN200 Control regulates plant growth and their natural defense system.
This ensures plants are better equipped against diseases and stresses such as extreme heat and cold.
Your plants will root faster and develop stronger stems and leaves, resulting in sturdier plants and higher yields. GEN200 Control can be used on all substrates and with all feeding systems.

Farmers can save money by using GEN200 Control, as the need for insecticides, fungicides, and pesticides is reduced.
Higher yields and better product quality with longer shelf life due to improved water retention in fruits and vegetables are other benefits.

Application Instructions

• Always add GEN200 Control to the nutrient solution before adding other nutrients.
• Add 15 ml per 100 liters of nutrient solution at each watering session.
• For foliar spray: apply 1 ml per liter of water.

Boost your plants’ defenses with a Control foliar spray

• Always add GEN200 Control to the nutrient solution before adding other nutrients.
• Add 15 ml per 100 liters of nutrient solution at each spray.
• For foliar spray: apply 1 ml per liter of water.
• Keep out of reach of children.
• Store below room temperature.

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

Control the height of your plants

Effective in managing vertical plant growth.
By giving plants higher doses of GEN200 Control, they receive increased levels of silicon in their system.
The physical effects of this silicon on the plant’s cell walls and outer layers prevent plant tissue from stretching.
The result is shorter plants with shorter internodal lengths and many side branches.

To slow vertical growth (stretching):
Increase application to 3 ml per 10 L in the nutrient reservoir.
