Hydroponics systems can be completely in liquid or use small amounts of soils. Most of the nutrients are fed into the water that the plant roots rest in. Additional foliar applications may or may not be made, depending on the grower.
Aeroponics is a growing technique where the plants are not in a media. The same dilutions used for foliar sprays would apply for aeroponics, using the foliar rates with nutrients on both the leaves and the roots.
3% solution EM•1® Microbial Inoculant several times per week.
Feed with a 2% solution of nutrients several times per week.
Water can also be conditioned using our 35mm Pipe Ceramics. For every 1,000 gallons of water in tanks, use 4 sets of the 35mm EMX Ceramic pipes. They can be put inside a 1 1/4" PVC pipe and plumbed directly into the main supply line. This will help condition the water and pull out dissolved solids in the water. If the unit is set up on a circulation system, you will notice it makes better use of the ceramics.
In the water lines, add EM•1® Microbial Inoculant starting at a rate of 1:1,000 (1 teaspoon per gallon) and as needed to maintain recommended dilution ratios with replacement water. Continue to use nutrient solutions as EM•1® is not a replacement for nutrients.
