Atami - B'cuzz Coco Bloom Stimulator

This is the coco version of the B'cuzz Bloom Stimulator. The honest version of this page starts with what Atami publish about the difference between those two bottles, because it is less than you would expect.

Atami publish no difference in composition

Put Atami's two product pages side by side and they are the same text, with "when cultivating on coco substrates" dropped in and one product swapped: this one is paired with B'cuzz Coco Booster, the other with B'cuzz Booster.

Neither has a published NPK, analysis or ingredient list, and nowhere is it stated that the formulas differ. They may differ. Atami do not say so, and so neither do we.

Our own page used to. It credited the bottle with a mechanism supposedly tuned to the fibre structure of coco. That came from nowhere, and it is hard to sustain beside Atami's own statement that this type of stimulator has almost no NPK value. A bottle that brings virtually no minerals with it cannot be tuned to how a substrate holds minerals.

So what is there to choose

This: which bottle belongs with the rest of your B'cuzz schedule. Atami pair each Bloom Stimulator with the booster from the same line, and on coco that is B'cuzz Coco Booster. If you grow on coco with the B'cuzz products, this is the matching bottle and there is nothing further to work out.

That is a duller answer than a story about fibre structure, but it is one you can build on. And it costs you nothing: the two versions come in the same sizes and the same price bracket, so there is no reason to take the "wrong" one hoping to save something.

When it goes in

As with the universal version, the moment is earlier than many people expect. Atami put it in as soon as the plant sets its first flowers, so just before it enters the bloom phase. After that you give it daily with the watering.

What it does, according to Atami, is kick-start the flowering phase and make it more intense and longer, with thick, compact flowers as the result.

Coco, and why a daily dose suits it

One thing genuinely is different about growing on coco, and it sits in the substrate rather than in the bottle. Coco holds little and is watered often, sometimes several times a day. So everything you supply, you supply in small portions at high frequency.

A stimulator you add to the feed water daily fits that well. On soil, where you water less often, the same instruction is a blunter measure.

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 in. Because there is almost no NPK in it, you do not have to pull your feed back for it.

Frequently asked questions

What is the difference with the regular Bloom Stimulator?
Atami publish no difference in composition. What they do pair up is the matching booster: here, B'cuzz Coco Booster.

Can I use the regular version on coco too?
Atami run this one as the coco version and pair it with the Coco Booster. If you grow on coco with the B'cuzz line, this is the matching bottle.

When do I start?
As soon as the plant sets its first flowers, so just before the bloom phase, and daily after that.

What is the NPK?
Atami publish no analysis. They state that this type of stimulator has almost no NPK value.

Do I need to adjust my EC?
No. With no meaningful NPK, the bottle adds little to your EC.
