Description
CANNA AQUA FLORES A&B 10 LITRE is the dedicated flowering-phase nutrient for recirculating hydroponic systems, and one of the most trusted base feeds in serious UK grow rooms. We have been recommending CANNA Aqua to hydroponics growers since 2017 because its formulation is built from the ground up for NFT, DWC, and RDWC systems — where nutrient concentrations must be precisely managed and reservoir chemistry consistency is everything.
What Makes CANNA Aqua Flores Different
CANNA Aqua Flores A&B is formulated with chelated trace elements and poly-silicic acid that remain stable in recirculating systems for much longer than standard nutrient salts, reducing the frequency of reservoir changes and the risk of precipitation blocking drippers or sprayers. The ratio of phosphorus to potassium in Flores is optimised for the explosive cell division and sugar loading of the flowering phase, while the calcium and magnesium levels are balanced to prevent the secondary deficiencies that commonly trip up growers who push EC too high in mid-late flower. The 10-litre twin pack provides excellent value for growers running larger reservoir volumes or multiple systems.
Feeding Schedule and Use in Recirculating Systems
Begin CANNA Aqua Flores from the first day of the 12/12 photoperiod switch. Start at 3ml per litre of each part (EC approximately 1.6–1.8 with clean RO water) and build to 4ml per litre per part (EC 2.0–2.4) by weeks three to four of flowering. Always add Part A to the reservoir first, circulate, then add Part B to prevent calcium-sulphate precipitation. Check EC and pH daily in recirculating systems — CANNA Aqua Flores performs best between pH 5.5 and 6.2. Drain and replace the reservoir every 7–10 days to prevent salt build-up and maintain nutrient balance.
Build the complete CANNA Aqua system by combining CANNA Aqua Flores A&B 10 Litre with CANNA Boost Accelerator and PK 13/14 for maximum flowering performance through the final weeks of your cycle.
