TopWet from Flairform is a wetting agent that increases the effectiveness of foliar sprays. It helps break the surface tension of water, which is what makes it form into droplets. In this state, it is harder for the leaf to absorb, not least because there is less surface contact. Breaking surface tension allows for faster penetration into the leaf, where the additive/ feed works quicker.

TopWet is effective with a whole range of sprayable products including fertilizers, fungicides and pesticides. Another benefit of increasing absorption is that there is less waste. TopWet is fully biodegradable and 100% non-ionic. Dose rate is 1-2ml per litre. Always give nutrients and additives a good shake before using. This will ensure all of the ingredients that may settle are back in the mix when pouring it out. Add each product to the nutrient tank one at a time, giving a good stir in between. Never mix concentrates together in neat form as they can react badly, causing clumping of some elements. This can cause malnutrition or ineffectiveness and is a waste of nutrient! We would always recommend following the manufacturer’s instructions for best results.
