Terpene Gold is Professor's Nutrients' certified organic flowering enhancer — built to push trichome density, sharpen aroma, and lift essential oil quality through the back half of bloom. Made in Australia from seaweed, fish, complex sugars, amino acids, plus humic and fulvic acid. OFC-certified organic, compatible with any base nutrient program (mineral or organic), and runs in soil, coco, or recirculating hydro. Available in 1L, 5L, 10L, and 20L.
Specifications
- Organic additives tend to pull pH down. Use an organic pH adjuster (not synthetic pH Up/Down) to keep your reservoir balanced.
- Mix Terpene Gold thoroughly into your nutrient solution before checking EC and pH — organics need agitation to dissolve evenly.
- Don't overdose. Start at 2 mL/L for early flower and only step up to 4 mL/L from week 3 onwards. More is not better.
- For DWC and recirculating systems, monitor reservoir cleanliness — organic inputs can build biofilm faster than mineral feeds.

Frequently Asked Questions
What does Terpene Gold actually do?
It's a flowering-stage additive that stimulates extra trichome (resin gland) sites on fruiting and flowering plants, while improving the quality of the essential oils those glands produce. The result is a stickier, more aromatic, more flavourful finish.
Is it compatible with my existing nutrient line?
Yes. Terpene Gold runs alongside any base nutrient program — mineral or organic — without conflict. It adds to your existing schedule rather than replacing anything.
Can I use it in coco or hydroponics?
Yes — works in soil, coco, and recirculating hydro. For DWC and ebb-flow systems, keep an eye on reservoir cleanliness, since organics can build biofilm faster than mineral-only feeds.
Is it safe for certified organic gardens?
Yes. Terpene Gold carries OFC certification (Organic Food Chain Pty Ltd), an approved organic certifying body recognised by the Australian Department of Agriculture. It contains no synthetic chemicals.
When in flower should I start using it?
From week 1 of flower at 2 mL per 1L of nutrient solution. Step up to 4 mL per 1L from week 3 onwards through to the final swell. Run it right through bloom for the full benefit.
Will it shift my pH?
Yes — organics typically nudge pH down. Always test and adjust after adding Terpene Gold to your reservoir, ideally with an organic pH adjuster to keep the whole system clean.
Can I use it as a foliar spray?
No. Terpene Gold is designed as a root-zone additive only. The fish and seaweed inputs aren't formulated for foliar application — apply it through your feed water.
How long does a 1L bottle last?
Roughly 250–500 L of finished nutrient solution depending on stage. At the higher 4 mL/L mid-bloom rate, 1L treats around 250L of feed water. For ongoing or larger grows, the 5L and 10L sizes deliver significantly better value per litre.
