CYCO Platinum Series Uptake | Humic Acid Additive Australia

CYCO Uptake

CYCO Uptake is a Platinum Series additive built around humic acid extracted from leonardite, a soft brown coal formed from partially decomposed plant matter. Humic acids are large carbon molecules with open bonding sites, and those sites latch onto metal ions such as iron, zinc and manganese. Bound that way, the mineral stays in solution and available instead of precipitating out or binding to the medium.

What It Does and What It Doesn't

Uptake is a biostimulant. It supplies almost no nutrition of its own, and the label reflects that honestly: 1% humic acids, 99% inert ingredients. There's no NPK figure because there's effectively no NPK in it.

That isn't a criticism. The job is to improve what your base nutrient already delivers, and humic acids are among the better researched biostimulants for exactly that. If your feed is correctly mixed and your pH is in range but plants still look like they're not getting everything, a chelating agent is a sensible next step before adding more fertiliser.

Two things worth knowing. CYCO's marketing describes Uptake as containing phosphorus. That doesn't appear in the guaranteed analysis, so don't buy it as a phosphorus source. And humic acid is not the same as fulvic acid, despite the two being sold side by side and often confused. Humic acid is the larger, less soluble fraction and does most of its work conditioning the medium and improving cation exchange. Fulvic is the smaller, more soluble fraction that moves more readily into the plant. Uptake is the humic one. If you specifically want fulvic, this isn't it.

Key Benefits

• Natural Chelation: Humic acids bind micronutrients and trace metals, keeping them in a form roots can absorb.
• Cation Exchange: Improves the medium's ability to hold and release nutrients, which matters most in coco and soil.
• Low EC Contribution: Adds almost nothing to your EC reading, so it layers onto an existing program without pushing the feed up.
• Works Across the Cycle: Used through both veg and flower rather than being stage specific.

How and When to Use

Mix 1ml per litre into your nutrient reservoir, through both vegetative and flowering stages. It suits recirculating and run-to-waste systems equally. Because it barely moves EC, you can add it to an existing program without recalculating your feed.

Frequently Asked Questions

Does CYCO Uptake contain fulvic acid?

No. The guaranteed analysis lists 1% humic acids derived from leonardite and 99% inert ingredients. Humic and fulvic acids are related but different fractions, and this product is the humic one. If you specifically want fulvic acid, you'll need a separate product.

Does Uptake contain phosphorus?

Not according to the label. CYCO's marketing mentions phosphorus, but the guaranteed analysis declares only humic acids and inert ingredients. Treat it as a biostimulant, not a nutrient source.

How does CYCO Uptake actually work?

Humic acids are large carbon molecules with open bonding sites that latch onto metal ions such as iron, zinc and manganese. Bound that way, the mineral stays dissolved and available to roots instead of precipitating out or locking to the medium. That process is called chelation.

Will Uptake fix a nutrient deficiency?

Only if the cause is availability rather than absence. If a nutrient isn't in your reservoir, a chelating agent has nothing to work with. Check pH and EC first, since lockout is far more common than genuine shortage.

Can I use CYCO Uptake in soil as well as hydroponics?

Yes, and soil and coco are where it earns its keep most, since humic acid also improves the medium's cation exchange capacity over time. That effect doesn't apply in a bare reservoir.

Can I use CYCO Uptake with other CYCO additives?

Yes. It runs alongside Silica, Zyme, B1 Boost and the rest of the range, and it contributes almost nothing to EC, so it doesn't crowd your feed.

What is the shelf life of CYCO Uptake?

Unopened, 2 years when stored cool and out of direct sunlight. Once opened, use within 12 months. Shake well before each use as humates settle.

Does CYCO Uptake ship fast within Australia?

Yes, CYCO Uptake ships from within Australia with fast tracked delivery Australia-wide. Most east coast orders arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
