Piensa En Verde presents Fertometer, a device that will facilitate your work in the cultivation of cannabis.
Measures the amount of fertilizer in the soil and pot plants. Inserting the metal tip and pressing the button gives you a reading by 3 leds.
The yellow LED indicates lack fertiliser, green indicates that the plant is well fertilized and red indicates over-fertilization; so the Fertometer allows to fertilize plants optimally. Craking!
The Fertometer can be used on indoor plants, outdoor, balcony, terrace and greenhouse plants.
