4-Part Mixing Instructions

Adjust the 4-part feeding chart to match the details of your garden.
Decide if you’re using silica (it’s not mandatory). If you’re using silica, always thoroughly mix it into the reservoir before adding any other products. You do not need to pH correct the water after adding the silica.
You can mix the 4-part in any order. The most important thing is to make sure each product is fully dissolved and mixed into the water before adding the next one.
Locate the “total grams” column for each product on the feeding chart.
Make sure the reservoir size is correct and weigh out the total grams of Grow from the chart. Add Grow directly to the reservoir and stir it into the water for several minutes. Once fully dissolved, continue with the other 3 products in the same way.
Once all the products are mixed, the pH will be between 5.5-6.3, depending on your water source. Check the EC/PPM and adjust the nutrient solution to your desired pH before watering.
