- A few drops of Dr Hydro Clear Mist into your humidifier prevents the build-up of algae and toxic microbes. Even if you don't suffer from algae growth, they're still a perfect environment for the growth of Legionnella bacteria. By using Dr Hydro Clear Mist, it's residual action means your humidifier is kept clean and sterile and remains active even after the water has evaporated!

Dosage for Clear Mist: For 5L add 15ml to the tank and shake. Larger humidifiers add 3ml/l. 

Dr Hydro Clear Mist can also be added to humidifiers that already have build-up algae or microbial growth. Clear Mist will remove the algae in 3 to 5 days. After this time shake the tank, and rinse with clean water. Refill with fresh water and a second dose of Clear Mist to provide long-lasting protection. 

DO NOT ADD MORE CLEAR MIST NEXT TIME YOU REFILL THE TANK WITH WATER. Simply just refill with fresh water. Only add more product after you have cleaned out the tank. 

This is NOT for us in nutrient tanks or hydroponic fertigation systems. Never mix with anything other than water. Keep out of reach of children. 

The specialized formula not only prevents the formation of algae but also inhibits the growth of toxic microbes, ensuring a clean and sterile environment within your humidifier.

Unlike ordinary treatments, Dr. Hydro Clear Mist's residual action continues to safeguard your humidifier long after the water has evaporated. Keep your indoor air quality pristine and your environment healthy with Dr. Hydro Clear Mist.

- Dr Hydro Venus Protection Spray is formulated for use on dioecious plant species. A dioecious plant will either be female (producing only female flowers), or male (producing only male flowers). However, under sub-optimal conditions a dioecious plant can turn hermaphrodite; producing both male and female flowers. In crops where female flowers are the harvestable crop, male flowers are a major hindrance as they produce pollen to fertilise the ovules in the female flowers. The resulting seed production reduces crop quality and yield. Therefore, keeping dioecious plant in optimal conditions with the biostimulants in Dr Hydro Venus protects your crop from major loss.


Dilute 50mL of the concentrate in one litre of clean water. Apply as a foliar spray to only the large older leaves at the bottom of the plant. Do not apply in temperatures greater than 26°C.

To minimise the risk of scorch, apply just before the lights are turned off for the night. Apply just before the photoperiod is reduced to initiate flowering. Apply a repeat application 7-14 days later.
