Atami - B'cuzz 1-Component Soil Nutrition

A complete mineral soil nutrient in a single bottle, for growth and bloom. Dose 5 ml per litre of water, that is 1 to 200, at half strength at the start of the grow and with one water-only feed each week.

One in two hundred, and once a week nothing

Two of Atami's instructions make this bottle usable, and both were missing from our page entirely.

The first is the ratio: 5 ml per litre, 1 to 200. At the start of the cycle you halve that. A young plant in fresh soil does not need the full dose and the soil is still contributing in the early weeks, so dosing full from day one only puts salt in the pot.

The second is the instruction almost nobody carries: once a week, give a feed of plain water with no nutrient in it.

That is not thrift, it is maintenance of your medium. At every feed something stays behind in the soil that the plant does not take up. Over weeks that builds, and soil with a raised salt level makes it harder for roots to take up water, which is exactly the picture that looks like a deficiency while there is in fact too much in there. A weekly run of clean water flushes part of it out of the pot before it accumulates.

Skip that weekly water and you will notice nothing for the first few weeks. Which is precisely why the instruction goes missing so easily.

What you give up and what you get back

This bottle is the counterpart to the two-part A+B in the same range. All the macro and micro elements are here in one pack, at a fixed ratio.

What you give up is the ability to steer. With the A+B you can give slightly more A in growth and slightly more B in bloom, and that dial is not here. The ratio is fixed for the whole cycle.

What you get back is that nothing can go wrong in the measuring. One bottle, one number, no two caps side by side and no chance of swapping A and B or pouring them together undiluted. For anyone mixing a tank after a long day that is a real advantage, and it is the reason this bottle exists.

So the choice between the two is not a difference in quality but a preference: do you want to steer, or do you want it to stay simple.

What it is meant for

This nutrient is calculated for potting compost and peat substrates, both pre-fertilised and low in nutrients. It is suitable for use with hard and with soft tap water.

For coco and for inert media this is not the right bottle: Atami have separate versions for those, because those media ask for a different ratio from soil.

The packaging is polyethylene and fully recyclable, free of PVC and cadmium.

Frequently asked questions

How much do I give per litre?
5 ml per litre, that is 1 to 200. Half that at the start of the cycle.

Why plain water once a week?
To stop salt building up in your soil. What the plant does not take up stays behind, and a weekly clean run flushes part of it away.

What is the difference from the A+B in this range?
That one lets you shift the ratio between growth and bloom yourself. This has a fixed ratio and is simpler to measure out as a result.

Do I need a flowering nutrient alongside it?
No, this covers growth and bloom. Separate stimulators are a choice, not a requirement to complete the base.

Can I use it on coco?
No, this is a soil nutrient. Coco and inert media ask for a different ratio and have their own version.
