Quick Turn by Growhard Australia is a two-part plant growth regulator (PGR) designed for application at the flowering-onset transition — the moment light hours are reduced to trigger bloom. The program runs as Part A first, then Part B exactly 3–5 days later, with dosage scaled to plant size from 30ml per plant at 60cm canopy up to 200ml per plant at 200cm. Compatible with both run-to-waste applications (direct medium dosing) and recirculating systems (reservoir dosing). The A+B Set covers a single full-cycle application across a small-to-medium grow. Manufactured by Growhard Australia, an established Aussie hydroponics additive maker since 1991.
PGRs are not recommended for use on consumption crops, as they are known carcinogens. For ornamental and decorative plants only.
Specifications
- Apply when plants haven't been fed recently and are looking for food — absorption happens within ~12 hours and you avoid run-off.
- Shake both bottles thoroughly before measuring each dose. Stratification in the bottle changes the effective concentration.
- Plan ahead for Part B — it follows 3–5 days after Part A. Write the date on the bottle when you open Part A so you don't miss the window.

Frequently Asked Questions
Can I use Quick Turn on consumption crops?
No. PGRs are not recommended for use on consumption crops, as they are known carcinogens. Quick Turn is for ornamental and decorative plants only — not vegetables, herbs, fruit, or any crops intended for human consumption.
What is Quick Turn and how is it different from regular A+B nutrients?
Quick Turn is a plant growth regulator (PGR), not a base nutrient. It's applied as a single-event two-step program — Part A then Part B 3-5 days later — at flowering onset, rather than being mixed into your regular feed schedule. Run your base A+B nutrients as normal; Quick Turn is a separate treatment on top of that.
When exactly should I apply Quick Turn?
Apply Part A when light hours are reduced to trigger flowering (the flip to 12/12 on photoperiod plants). Follow with Part B exactly 3-5 days later. Don't apply during vegetative growth or mid-bloom — the timing window is specifically the flower-onset transition.
How do I work out the dose for my plants?
Measure each plant's height and width. The dosage chart is: 30ml per plant at 60cm, 50ml at 90cm, 100ml at 135cm, 200ml at 200cm. Pour the per-plant dose into 2 litres of water before applying directly to the medium.
Can I use Quick Turn in a recirculating system?
Yes. Calculate the total amount needed across all plants in the system and add it directly to the reservoir or tub. For example: 3 plants at 105cm × 105cm canopy = 70ml each, so add 210ml of Part A total to the reservoir. Repeat with Part B 3-5 days later.
Do I need both Part A and Part B?
Yes — the program requires sequential application of both parts. The A+B Set includes both 200ml bottles. The single-part variants (Part A or Part B at 200ml each) are for replacing one bottle if you run out of one component before the other.
