TLDR: Flushing in a Nutshell
Flush for Flavour, Not Starvation
- Flushing = plain water before harvest to remove nutrient build-up.
- Going nutrient-free for 1–2 weeks can starve plants — not ideal.
- Best method: 10 days Dragon Force®, then 4-day light flush.
- Dragon Force feeds & ripens while clearing salts.
- Sulphur content = richer aromas & smoother taste.
Result: Clean, flavour-packed produce that finishes strong.
Flushing — it’s one of those topics that gets growers talking. Some swear by it, others call it a waste of time. So, what’s the real deal?
What Flushing Actually Is
Flushing means switching to plain water for the last 1–2 weeks before harvest, aiming to wash out any nutrient build-up. The goal? Cleaner-tasting flowers without harsh residues.
In coco, which tends to hold onto salts, flushing can be especially helpful. But do it wrong, and you risk starving your plants when they still have work to do.
The Great Debate
- Anti-flushers say it strips plants of nutrients they still need, stressing them unnecessarily. Some even point to blind taste tests where unflushed produce scored higher.
-
Flushers argue it’s essential for smoother, cleaner produce, claiming it helps remove excess salts and can even trigger more aromatic compounds.
Our Take at Shogun Fertilisers
Flushing works — if you do it strategically. Instead of going cold turkey on nutrients, give your plants a final, targeted push before the flush.
That’s where Dragon Force® comes in. It’s a high-quality late flowering feed that replaces your bloom + PK products for the last 10 days, delivering phosphorus, potassium, magnesium, and sulphur to drive ripening, resin production, and flavour development.
After 10 days of Dragon Force, finish with a light 4-day flush of plain water. This way, you get the benefits of flushing without starving your plants in the home stretch.
Why Sulphur is a Star Player
Dragon Force’s sulphur content helps build the essential oils that make your crop taste and smell incredible. It’s the secret weapon for top-shelf finish quality.
The Bottom Line
Don’t think of flushing as “all or nothing.” Think of it as a two-step finish:
- Dragon Force® for 10 days – ripen, bulk, and polish your crop.
- 4-day mild flush – clean out excess salts and lock in flavour.
Your plants — and your taste buds — will thank you.
