CANNA BOOST Accelerator is a flowering additive used alongside a suitable base feed. It is different from CANNA PK 13/14, and it is not a replacement for the main nutrient programme. Check which bottle you have before using a dose or schedule found online.
This guide explains the product's role, the manufacturer's key instructions and how to calculate the amount needed for a batch. It covers CANNA BOOST Accelerator; CANNA Bio Boost is a separate product.
What is CANNA BOOST used for?
CANNA describes BOOST Accelerator as a flowering stimulator for use with regular feeding. The manufacturer positions it for flowering and fruit development across growing media. Treat performance claims as manufacturer claims, rather than a guaranteed result for your crop.
Before adding another bottle to a programme, check that the basics are consistent: suitable nutrition, light, irrigation and growing conditions. An additive does not establish that a poorly performing plant needs more fertiliser.
When do you start using CANNA BOOST?
CANNA's published instructions start from the formation of flowers. Its stated dilution is 20ml per 10 litres of water, with 40ml per 10 litres listed for extra flowering strength. That is 2–4ml per litre. Follow the current bottle label and crop-specific schedule; the upper figure is not automatically the right choice.
How much do I add to my water?
Product needed in ml = water volume in litres × the chosen labelled dose in ml/L. These calculations illustrate the manufacturer's 2ml/L and 4ml/L figures; they do not select the dose for your plants.
| Water volume | At 2ml/L | At 4ml/L |
|---|---|---|
| 2 litres | 4ml | 8ml |
| 5 litres | 10ml | 20ml |
| 10 litres | 20ml | 40ml |
| 20 litres | 40ml | 80ml |
Use an appropriate measuring tool and record what you added. A batch note can include the date, water volume, base feed, additives and crop stage. It makes repeated batches easier to compare and helps avoid accidentally adding the same product twice.
CANNA BOOST versus PK 13/14
BOOST Accelerator and PK 13/14 have different roles. PK 13/14 supplies additional phosphorus and potassium; CANNA's current product instructions say to add it three weeks before harvesting and use the mixture for 3–6 days. Match that instruction to the complete feeding schedule and your crop. Do not copy that timing onto BOOST or assume that adding one means the other must be used.
Choose any combination against the full nutrient schedule and the crop's needs. Avoid adding several products with overlapping purposes simply because each is described as a booster.
Important mixing and storage instructions
CANNA says to shake BOOST before use, avoid combining it with hydrogen peroxide products, and use diluted solution within four days. Store the closed bottle away from light and frost, and keep it out of children's reach. Check your current label for the complete instructions.
Although the manufacturer lists several application methods, this article does not provide a foliar spraying programme. Confirm crop and application suitability before moving from root feeding to spraying leaves.
Which bottle size makes sense?
Compare the quantity of finished feed you expect to prepare with the bottle volume. Purely by arithmetic, 1,000ml supplies 500 litres at 2ml/L, or 250 litres at 4ml/L. That is a volume calculation, not a recommendation to store mixed solution.
For example, four separate 10-litre batches at 2ml/L use 80ml in total. Write out your own likely batches before choosing a bottle. Compare the selected size and current price on the CANNA BOOST product page; prices and availability can change.
Common questions
Can BOOST replace the base feed?
No. Use it alongside an appropriate main nutrient programme.
Is CANNA BOOST the same as Bio Boost?
No. Check the full product name and use the instructions for that specific product.
Should I use more if my plants look stressed?
Do not increase a dose to treat an unidentified problem. Review the environment, irrigation and existing feed first, and ask for advice with the full programme to hand.
