Canna Boost Accelerator — Flowering Stimulator for Higher-Quality Harvests
Best for: Growers wanting to boost plant metabolism and improve flower quality without overspending on premium bloom boosters
Our thoughts
Canna Boost is the classic flowering accelerator for good reason. It works across every system, plays nicely with whatever nutrients you're running, and genuinely improves flavour and finish. That said, there are stronger alternatives at better prices these days — but if you rate the reliability and want a trusted name, this delivers.
Canna Boost Accelerator is a liquid flowering stimulator designed to increase plant metabolism during the bloom phase, improving photosynthesis and pushing plants to develop stronger, more uniform flowers. Made from fermented plant extracts (primarily sugar beets) with naturally occurring amino acids and carbohydrate chains, it works in every growing medium — soil, coco, hydro — and every feeding system without exception. Start it once flowering begins and you'll see faster flower formation, improved taste, and cleaner finishes.
How it compares
This sits in the premium-priced bloom booster bracket.
- Works universally across all systems and compatible with any base nutrient
- No plant growth regulators — purely metabolic support through carbohydrates and amino acids
- Stronger competitors like SHOGUN Sumo Boost offer double the concentration at significantly lower cost
- If budget's tight, explore alternatives — but Canna Boost trades on proven track record and universal compatibility
Bottom line: premium pricing, proven results, but not the only option out there.
Usage guidance
Canna Boost is straightforward to use once flowers start forming:
Tank mixing (standard method)
Add 2ml per litre of water from the moment flowering begins. For increased flowering support, use 40ml per 10 litres. Compatible with every base feed and works alongside PK 13/14 boosters if you're running them.
Foliar feeding
Can be diluted and sprayed directly onto foliage for faster absorption. Apply in low light to avoid leaf burn.
Timing and duration
Use throughout the flowering cycle. Diluted solution stays active for four days — don't make up more than you'll use in that window.
Key compatibility note
Do not mix with products containing hydrogen peroxide. Works in hard or soft water without issue.

Who this is for
- Growers already familiar with and trusting Canna products
- Anyone running a universal nutrient setup who wants a booster that plays nice with everything
- Experienced growers prioritising proven performance over cost optimisation
- Hydro, coco, and soil growers wanting the same reliable additive across different setups
Less ideal if you're budget-conscious and comparing every penny — stronger, cheaper bloom boosters exist, but Canna Boost remains a solid choice if reliability and compatibility matter more than value-for-money.
Our take
This is a legitimate flowering stimulator that does what it claims. It boosts plant metabolism, supports faster flower development, and noticeably improves taste — growers have been running it for years for good reason. The compatibility across all systems is genuinely useful if you switch between setups or grow multiple crops.
That said, be honest about the price. Premium bloom boosters are premium-priced. If you've got the budget and want a trusted name that won't complicate your feeding schedule, worth picking up. If every quid counts, research alternatives first — there are stronger options at lower cost.
