Canna Boost Accelerator

Canna Boost Accelerator — Canna's Flowering Stimulator

Canna Boost Accelerator is Canna's flagship flowering stimulator, developed for short-cycle plants. Unlike most "boosters", it isn't extra nutrition — it's an additive that raises your plant's metabolism and rate of photosynthesis, so the feed you're already giving gets converted into flower faster. The result is fuller flowering sites, more even ripening and a noticeably sweeter, more aromatic finish as sugar production climbs.

It works in any medium and any system — soil, coco or full hydro — alongside any Canna base feed.

How to use Canna Boost

• When: start from the moment flowers begin to form, and use through the flowering phase.
• Dosage: 20ml per 10 litres of water (1:500). For extra flowering strength, Canna recommends up to 40ml per 10 litres (1:250).
• How: add to your normal feed water, or apply as a foliar spray for direct uptake through the leaves.
• Never use alongside products containing hydrogen peroxide (H₂O₂) — it destroys Boost's organic compounds.

Exact tank strengths for every stage are in our feed chart guide, which covers the full Canna schedule for both Terra and Coco.

Boost and PK 13/14 — Canna's own pairing

Canna's official guidance is that the highest yields come from running Boost together with PK 13/14: PK supplies the extra phosphorus and potassium flowering demands, while Boost drives the metabolism that turns those minerals into weight. Many growers also run Cannazym throughout to keep the root zone clean while the plant is working at this higher rate. In the final week, switch additives off and finish with Canna Flush for a clean-tasting harvest.

Why growers rate it

• Stimulates new flower development for heavier, denser fruits
• More uniform ripening — a more consistent harvest in one pass
• Higher sugar production for better taste and stronger aroma
• Supports the plant's natural resistance during its most vulnerable phase
• No PGRs — a fermented plant-extract formulation, safe on edible crops

Frequently asked questions

What's the correct Canna Boost dosage?
20ml per 10 litres (2ml/L) from first flowers, rising to 40ml per 10 litres (4ml/L) for maximum flowering strength. Full stage-by-stage rates are in our Canna feed chart guide.

Is Canna Boost the same as PK 13/14?
No — they do different jobs. PK 13/14 is a mineral additive (extra P and K); Boost is a metabolism stimulator. Canna designed them to be used together during flowering for the best results.

Can I use Canna Boost in soil, coco and hydro?
Yes — Boost is formulated for every medium and system, and works alongside any Canna base nutrient.

When should I stop using it?
Run Boost through flowering, then stop your additives when you begin your end-of-cycle flush with Canna Flush.

Can I mix it with hydrogen peroxide?
No. H₂O₂ kills the organic compounds Boost relies on. Keep any peroxide-based products out of the same reservoir.
