1. Measure your current EC (Electrical conductivity), making sure your EC meter has been recently calibrated.
2. Choose the desired crop type (your crop type) and set your nutrient mix tank (re-circulation) size in Liters (L).
3. Then drag the circle selectors to set the (your) current source and desired target EC (Electrical conductivity).
- Note: Apple iOS browser sometimes has issues displaying the round sliders so please use the middlemost numeric text value to set the source and target EC values.
The calculation will provide you with a guideline on how many grams of each product to add to your nutrient tank. Be sure to first dissolve the suggested nutrient amounts into a smaller amount of water (concentrate), then only add to your nutrient mix/re-circulation tank. Check readings again after a minimum of 2 hours/daily and re-perform the calculation.
Note: This concentrated mix can be harmful to your eyes and skin as it's fairly acidic.
Being acidic it will also lower the pH of your nutrient tank slightly (approximately 3%) based on the volumes added. A natural pH down.
