Quick Answer

Low-concentration finishing additive for the last few weeks of bloom. Registered analysis 0.6-3-2.
Phosphorus and potassium weighted, with a small amount of nitrogen. It is not a magnesium product.
CYCO's claim is improved resin, fruit size and quality. We can't independently verify that, so treat it as a finisher rather than a fix.
Used at 1ml per litre in the final four weeks only.
Ships fast from within Australia.

CYCO Supa Stiky

CYCO Supa Stiky is a Platinum Series finishing additive run in the last stretch of bloom. It's a dilute phosphorus and potassium feed with a small amount of nitrogen, made to food grade standards because it's applied to crops close to harvest.

What It Is, Honestly

Supa Stiky is marketed around resin and essential oil production. That's CYCO's claim and we're not going to repeat it as though it were established fact, because the registered analysis doesn't contain anything exotic. It's 0.6% nitrogen, 3% phosphate and 2% potash. There's no magnesium in it, despite what you may read elsewhere, including on our own page until we checked.

What that composition actually supports is straightforward. Phosphorus and potassium are both used heavily through fruit and flower development, and potassium in particular drives the movement of sugars from the leaves into the flower. A plant that's short of either in the final weeks will finish lighter and less dense than one that isn't.

What it won't do is create terpenes out of nothing. Aroma and essential oil content are set mostly by genetics, light quality and how well you manage temperature and humidity through the finish. If those are wrong, no bottle corrects them.

If you're only buying one late-flower additive, Swell at 1-5-3 gives you considerably more phosphorus and potassium for a similar price. Supa Stiky is a supplementary finisher, not a replacement for it.

Key Benefits

Late Stage PK: 3% phosphate and 2% potash to support fruit and flower development in the final weeks.
Sugar Movement: Potassium drives phloem transport, moving sugars out of the leaves and into the flower.
Food Grade Inputs: Made from food grade ingredients, which matters on consumable crops close to harvest.
Gentle Concentration: Dilute enough to layer onto an existing feed without a large EC jump.

How and When to Use

Use in the last four weeks of bloom only, at 1ml per litre, alongside your base nutrient. It runs happily with Swell and Suga Rush, neither of which conflict with it, but three additives on one feed adds up. Check EC after mixing rather than assuming.

Frequently Asked Questions

Does Supa Stiky contain magnesium?

No. The registered analysis is 0.6-3-2, nitrogen, phosphate and potash. Several retailers describe it as a magnesium product and that isn't supported by the label. If you need magnesium, use a Cal-Mag product or Epsom salts.

Will Supa Stiky increase terpenes or aroma?

That's the manufacturer's claim and we can't verify it independently. What the analysis supports is extra phosphorus and potassium through the finish, which helps flowers fill properly. Aroma is driven far more by genetics, light and how you manage temperature and humidity in the final weeks.

Supa Stiky or Swell, if I'm only buying one?

Swell. At 1-5-3 it carries considerably more phosphorus and potassium than Supa Stiky's 0.6-3-2 for a similar price, so it does more of the work in late flower. Supa Stiky is a supplementary finisher on top.

When do I start using CYCO Supa Stiky?

The last four weeks of bloom only. It isn't used in vegetative growth or early flower.

Can I use CYCO Supa Stiky alongside Swell or Suga Rush?

Yes, none of the three carry a conflict warning. Follow the dose for each and watch total EC, since stacking additives raises it faster than growers expect.

Can I use CYCO Supa Stiky in soil as well as hydroponics?

Yes. Soil buffers nutrients, so start at a reduced rate and adjust based on plant response.

What is the shelf life of CYCO Supa Stiky?

Unopened, 2 years when stored cool and out of direct sunlight. Once opened, use within 12 months.

Does CYCO Supa Stiky ship fast within Australia?

Yes, CYCO Supa Stiky 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.
