Atami - B'cuzz Bloom Stimulator

The B'cuzz Bloom Stimulator is meant for one specific moment, and that moment falls earlier than most people expect. Atami put it in as soon as the plant starts forming flowers, so just before it enters the flowering phase.

The timing is the product

Atami's own description is precise: you apply the Bloom Stimulator when the plant starts forming flowers, just before it enters the bloom phase. What it then does is kick-start that phase and make it more intense and longer-lasting.

That is a different kind of product from the PK bottles further along this shelf. Those go in weeks later and work on what the plant has already set. This one works on the setting itself. Reach for it once your tops are already standing and you have missed the window it was built for.

After that you give it daily with the watering, from flower formation onward. So it is not a weekly intervention but a fixed part of your schedule.

Why it fits beside any base feed

Atami give the reason themselves: the Bloom Stimulator has almost no NPK value, which is what makes it combinable with practically all base nutrients.

There is a second consequence they do not spell out but you notice at once. A bottle with no meaningful NPK adds little to your EC, so you do not have to pull your base feed back for it. That is exactly the opposite of what a PK ripener asks of you.

What Atami do not publish is an analysis. No NPK, no percentages, no ingredient list for this product. So we add no figures either; "almost no NPK value" is their phrasing and we leave it as it stands.

What Atami claim happens

A more intense and longer flowering phase, resulting in an abundant production of thick, compact flowers and eventually fruits that taste and smell good. Atami add that the best effect comes in combination with B'cuzz Booster, their stimulator for the wider plant processes.

They also name the product firmly outside the tent: vegetables, fruits and herbs such as tomato, sage and basil, and indoor and potted plants. The dose can be matched to the needs of an individual plant or crop.

In use

Mix 0.5 to 1.0 ml per litre of feed water, daily, from the first flower formation. Add it once your base feed is already in the water.

For coco, Atami run a separate version, the Coco Bloom Stimulator. They publish no compositional difference between the two; what they do pair up is which booster goes with which, B'cuzz Booster with this one and B'cuzz Coco Booster with the other.

Frequently asked questions

When should I start?
As soon as the plant sets its first flowers, so just before it enters the bloom phase. Start later and you miss the window it is meant for.

Do I have to adjust my base feed?
No. Atami state the product has almost no NPK value, which is what makes it combinable with practically any base feed.

What is the difference with the coco version?
Atami publish no compositional difference. What they do pair up is the matching booster: B'cuzz Booster with this one, B'cuzz Coco Booster with the coco version.

How often do I give it?
Daily with the watering, from flower formation onward.

Is this the same as a PK?
No. A PK brings phosphorus and potassium and goes in weeks later; this one works on the setting of the flowers themselves.
