The Marketing Claim & The Catch

A typical 75 g tub pack of Doff Natural Hormone Rooting Powder is about £4.99 in lawn & garden. That is a snapshot, not a live Amazon price — listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.

On the pack: Encourages rapid root strike in soft, semi-hard and hardwood cuttings; and Helps prevent basal fungal rot in fresh cuttings.

The catch: A 75 g tub is 74.9 g of talc carrying 75 mg of IBA. That is about £67/kg for cosmetic powder. 0.5 g of pure IBA in 500 g of unscented talc is the same 0.1% dip.

Proprietary Blend & Dosage Breakdown

The labelled active is Indole-3-butyric acid (IBA) at 0.1%. Everything else in the pack is talcum powder (99.9%).

At 0.1% active, most of what you pay for is carrier and packaging. The brand is selling convenience, fragrance and a label — not a uniquely potent molecule.

Branded working strength is whatever comes out of the bottle. The bulk alternative is 99% Indole-3-butyric acid (IBA), mixed to 0.1% w/w in talc (0.5 g IBA per 500 g talc).

The Active Chemical Alternative (Dupe Stack)

The dupe stack is Indole-3-butyric acid (IBA) at 99% bulk. Indexed as CAS 133-32-4, formula C12H13NO2. Buy it as 1 g IBA (makes 1 kg of 0.1% powder) for about £8.50 from Amazon UK.

Working strength: 0.1% w/w in talc (0.5 g IBA per 500 g talc). Indicative cost £0.01 per diluted litre — 87% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.

Follow the mixing method and the supplier SDS. Wear the listed PPE. Do not mix incompatible oxidisers, acids or ammonia.

  1. IBA is a plant-growth regulator. Wear gloves and an FFP2 mask; weigh in a still room. Keep away from children.
  2. Dissolve 0.5 g of IBA in about 20 ml of isopropyl alcohol.
  3. Fold into 500 g of unscented pharmaceutical talc until evenly damp. Spread thin and dry. That is 0.1% IBA — the same strength as the 75 g tub.
  4. Dip the cut base, tap off surplus, and strike as usual. 1 g of IBA makes about 1 kg of finished powder (roughly thirteen 75 g tubs).

Active ingredient and cheaper alternative — FAQ

What is the active ingredient in Doff?

Doff Natural Hormone Rooting Powder is labelled as Indole-3-butyric acid (IBA) at 0.1%. The carrier is Talcum powder (99.9%). Pack size: 75 g tub. The bulk equivalent we index is Indole-3-butyric acid (IBA) (CAS 133-32-4).

Is Indole-3-butyric acid (IBA) safe on lawns?

Used at the listed working strength (0.1% w/w in talc (0.5 g IBA per 500 g talc)), the dupe is the same chemistry as the branded pack for lawns, beds and pots. That is not a blanket all-clear: read the supplier SDS, wear the listed PPE, keep acids away from hypochlorite, and follow UK HSE/COSHH rules. Wellness teardowns are supplements, not medicines.

Is there a cheaper alternative to Doff Natural Hormone Rooting Powder?

Yes. The bulk equivalent is Indole-3-butyric acid (IBA) (CAS 133-32-4). Indicative saving 87% per working litre versus a typical £4.99 pack. Working strength: 0.1% w/w in talc (0.5 g IBA per 500 g talc). Live shop prices move.

How do you mix the Natural Hormone Rooting Powder dupe stack?

IBA is a plant-growth regulator. Wear gloves and an FFP2 mask; weigh in a still room. Keep away from children. Dissolve 0.5 g of IBA in about 20 ml of isopropyl alcohol. Fold into 500 g of unscented pharmaceutical talc until evenly damp. Spread thin and dry. That is 0.1% IBA — the same strength as the 75 g tub. Dip the cut base, tap off surplus, and strike as usual. 1 g of IBA makes about 1 kg of finished powder (roughly thirteen 75 g tubs).
