Canna Fertilizers: Premium Nutrition for Your Indoor Crops
Canna is THE Dutch benchmark for indoor growing fertilizers. For over 30 years, this brand has been developing formulas specifically adapted to the needs of indoor plants, whether grown in soil, coco, or hydroponics. Their Terra, Aqua, and Coco ranges offer complete and balanced nutrition for each growth phase.
Why choose Canna fertilizers for your cultivation
Canna fertilizers stand out for their ultra-pure formulation and perfectly adjusted pH. Unlike general-purpose fertilizers, each Canna product is designed for a specific substrate. Terra Vega and Terra Flores form the basic duo for soil cultivation, with optimized NPK ratios: 3-1-3 for growth and 2-2-4 for flowering. This precision in dosages prevents deficiencies and excesses that can hinder development.
Canna additives like Rhizotonic (root stimulator) and Cannazym (enzymatic complex) perfectly complement the basic range. Rhizotonic contains vitamins B1, B2, and trace elements that boost rooting from the very first days. Cannazym, on the other hand, breaks down dead roots and improves nutrient absorption by 15 to 20% according to the brand's internal tests.
How to choose your Canna fertilizers
The choice primarily depends on your substrate. For soil, opt for the Terra range with Vega (growth) and Flores (flowering). For coco, prefer Coco A+B, which takes into account the specific cation exchange capacity of coco fiber. In hydroponics, Aqua Vega and Aqua Flores are formulated for pure water with ultra-stable EDDHA iron chelates.
Regarding dosage, Canna recommends 2.5ml/L for Terra Vega during growth and 2.5ml/L for Terra Flores during flowering. These concentrations can be adjusted according to the EC of your base water: if it exceeds 0.4 EC, slightly reduce the doses. The Canna advantage is its tolerance to variations: their pH buffers prevent sudden drops even with hard water.
Frequently Asked Questions
Which Canna Terra fertilizer should I choose for the vegetative phase in soil, Terra Vega or another?
Terra Vega is indeed the reference fertilizer for the vegetative phase in soil. Its 3-1-3 formula provides the nitrogen necessary for foliar development while maintaining a good phosphorus-potassium balance. You can use it from the 3rd week after germination at 1.25ml/L, then gradually increase to 2.5ml/L. Terra Vega also contains humic acids that improve soil structure and water retention, a significant plus in indoor cultivation where watering must be precise.
Should I add Rhizotonic and Cannazym with Canna Terra fertilizers to boost roots?
Rhizotonic is particularly useful during the first 2-3 weeks of growth and during repotting to stimulate rooting. Dosed at 4ml/L, it accelerates recovery and reduces stress in young plants. Cannazym, on the other hand, is essential in long-term cultivation (more than 10 weeks) as it breaks down dead roots that naturally accumulate. These enzymes release directly absorbable sugars and minerals, which boosts beneficial microbial activity around the roots. In soil, use Cannazym at 2.5ml/L once a week.
How to precisely dose Terra Vega and Terra Flores in ml/L to avoid over-dosing?
The standard dosage is 2.5ml/L for each fertilizer, but adjust according to your target EC and water quality. During growth with Terra Vega, aim for 1.2 to 1.6 total EC. During flowering with Terra Flores, gradually increase up to a maximum of 1.8-2.0 EC. If your base water is already 0.3-0.4 EC, start with 2ml/L and adjust. The classic pitfall: wanting to push too hard at the beginning of flowering. It's better to slightly under-dose than to block absorption with an excess of salts.
Terra Vega or Terra Flores, which is better for transitioning from growth to flowering?
The transition is done gradually over 7-10 days by mixing the two fertilizers. Week 1 of flowering: 75% Terra Vega + 25% Terra Flores. Week 2: 50/50. From week 3, switch to 100% Terra Flores. This method avoids nutritional shock because plants still need nitrogen at the beginning of the stretch. Terra Flores contains less nitrogen (2% vs 3% for Vega) but more phosphorus and potassium to support flower formation. Never abruptly switch from one fertilizer to another.
How to maintain the soil substrate with Cannazym for better absorption of Canna fertilizers?
Cannazym is ideally used once a week at 2.5ml/L mixed with your usual nutrient solution. These enzymes (cellulase, pectinase, xylanase) break down dead organic matter and transform root residues into available nutrients. In soil, this improves substrate porosity and prevents salt accumulation. Alternate: one week with Cannazym, one week without, to allow new roots to develop. At the end of cultivation, use Cannazym with each watering during the last 2 weeks to clean the substrate.
