CANNA Boost Accelerator is a flowering stimulator designed to increase the number and size of flower sites, improve fruit production, and enhance the flavour and aroma profile of your harvest. It works alongside your base nutrient programme from the start of flowering through to flush — not as a replacement, but as an additive that pushes the generative phase further than base nutrients alone can achieve. Compatible with all substrates and nutrient systems, it is one of CANNA's most widely used additives across both soil and hydro grows.
Specifications
- Start Boost from the first day of flowering rather than waiting until mid-flower — the flower site stimulation effect works best when applied from the very beginning of the generative phase.
- Boost can be used alongside CANNA PK 13/14 during the peak flowering weeks — they target different aspects of bud development and stack well together.
- Do not stop Boost during the flush period — continue until your final plain water flush to maximise flavour and aroma development right through to harvest.
How to Use

Frequently Asked Questions
Can I use Boost with non-CANNA base nutrients?
Yes. Boost is compatible with any base nutrient programme regardless of brand or substrate. It is not exclusive to the CANNA system and performs consistently across soil, coco, and hydro grows.
When should I start using Boost?
From the first day of the flowering phase. Starting Boost at the flip rather than mid-flower gives the flower site stimulation effect the maximum window to work — waiting until week 3 or 4 leaves results on the table.
Does Boost replace PK 13/14?
No. They serve different purposes and stack well together. PK 13/14 is a phosphorus and potassium supplement applied during peak flower development. Boost is a flowering stimulator focused on increasing flower sites, aroma, and fruit quality — it runs throughout the entire flowering phase rather than just peak weeks.
Will Boost raise my EC?
Yes. Boost contributes to total EC — account for its dosage when calculating your overall feed EC to avoid overfeeding, particularly if you are already running additional additives alongside your base nutrient.
Which size should I buy?
The 250ml suits a single plant or a trial run to assess results. The 1L is the most practical size for 2–6 plant grows running a full flowering cycle. The 5L is for larger operations where buying in bulk reduces cost per feed significantly.
