How To Use

Using Canna Hydro Flores HW A&B

Fill your run-to-waste hydroponic system reservoir with water and add equal amounts of Canna Hydro Flores HW Part A and Canna Hydro Flores HW Part B to the tank to achieve the required strength and mix well. Use 2-4ml/litre (CF of 18-27) of both part A and part B using 2ml/litre for very light-feeding plants and up to 4ml/litre for heavy feeding plants. We recommend using a syringe or beaker for accurate measurement of this product and a CF/EC/PPM meter such as the Bluelab Truncheon to check the nutrient strength. Adjust as necessary. Next, add any additives and boosters you wish to use and again mix well. Adjust the pH of the solution to the required level using pH up or down as necessary. We recommend the use of a pH meter such as the Horticare pH meter to help accurately set the pH to the required level. It is recommended you renew the nutrient solution in your reservoir every 7 days. Canna recommend achieving 10%-20% run-off at each watering with this product.

Manufacturer's recommended dosage rates are only for vigorously growing plants that are in the peak of health. Slower growing plants and those that are not 100% healthy will require a lower dosage rate.
