Hello –
SM-90 is prepared from natural plant oils, like coriander (1.0%) and canola (94%). This multipurpose wetting agent also includes triethanolamine (5.0%), which can be found in up to 40% of beauty and personal care items currently on the market. According to the manufacturer, Nutrilife Plant Products, SM-90 is biodegradable and non-toxic to humans, animals and plants. It can be applied as a foliar spray or directly in reservoirs with nutrient solutions.
The only precautions listed on the product label are:
Avoid contact with eyes, skin, open cuts or sores. Keep out of reach of children. Wash hands after use. For general cleanup, use strong detergent or pine-oil cleaner.
There is NO information about protective clothing or masks on the container. I have included the directions for use below:
HYDROPONIC SYSTEMS
Apply 2-3 ml of SM-90 to each gallon of nutrient solution on a weekly basis or whenever solutions are replaced.
FOLIAR SPRAYS
Dilute 1 part SM-90 with 5 parts water to prepare a Foliar Spray. May be repeated every 3 days for up to 3 spray applications.
Happy gardening!
