Atami B'Cuzz Bloom Stimulator - Daily Flowering Booster for Soil Grows
Best for: soil growers who want a simple, everyday additive that kicks the flowering phase into gear without recalculating their whole feed schedule.
Our thoughts
This is Atami's mainline bloom stimulator, not to be confused with their premium Bloombastic booster - it's the everyday one you dose from the start of flower right through to the end, rather than a late-flower finisher. Because it carries almost no NPK value of its own, it drops straight into whatever base feed you're already running without upsetting the balance.
B'Cuzz Bloom Stimulator is a liquid additive applied from the point a plant starts forming flowers. It's designed to trigger and intensify the flowering response, aiming for thicker, more compact flowers and fruit that develop more flavour and aroma as they mature. Because the formula carries almost no NPK value of its own, it can be combined with practically any base nutrient without throwing off your feeding ratios - Atami states a dilution rate of roughly 1:1000 in the finished nutrient solution.
It's part of Atami's core B'Cuzz range (as distinct from the premium Bastics line, which includes the more concentrated Bloombastic), and is best used daily throughout the entire bloom phase rather than saved for the final weeks.
How it compares
Bloom stimulators are one of the most crowded categories in the nutrient aisle, and B'Cuzz Bloom Stimulator competes on being simple and low-cost to run daily.
- Used throughout the whole bloom phase, unlike late-stage PK boosters such as Canna PK 13/14 or House & Garden Bud-XL, which are typically added only in the final weeks.
- Sits below Atami's own Bloombastic in concentration and price - Bloombastic is a finishing booster, this is an everyday one.
- Comparable role to Advanced Nutrients Big Bud, though with a lower NPK contribution, making it easier to layer onto an existing base feed without recalculating ratios.
If you're after a big late-flower push on top of your existing feed, pair it with a dedicated PK finisher; if you want one product to run daily through bloom, this covers that job on its own.
Usage guidance
Start dosing as soon as flowers begin forming and keep going through to near the end of bloom.
Dosage
Use 0.5-1ml per litre of water, added to your feed at every watering during the bloom phase.
Combining with other products
Because it's virtually NPK-neutral, it mixes freely with your existing base nutrient - Atami suggests the best results come from pairing it with B'Cuzz Booster.
Timing
Begin as flower sites first appear and continue daily until the last week or two before flush.

Who this is for

- Growers already on a base nutrient who want to add a flowering boost without recalculating feed strength.
- Anyone who wants an entry point into the Atami range before stepping up to Bloombastic.
Best suited to growers who want one consistent bloom additive running through the whole flowering phase.
Our take
It's not flashy, but it does exactly what a daily bloom additive should - drop it in from the start of flower and let it work in the background alongside whatever base feed you're running. The near-zero NPK value is genuinely useful here, since it means no juggling ratios.
If you want a straightforward bloom stimulator without stepping up to a premium finisher, this is the one to reach for. Does exactly what it should, day in, day out.
