Buyer FAQs
What is Regulator Bud Fast Part B?
It is a concentrated Nutrifield plant growth regulator for controlled flowering-stage use where permitted by the current product label. It is not a complete base nutrient.
What size is supplied?
This listing supplies one 1 litre handled bottle.
What is the mixing rate?
The listed rate is 1 mL per litre of nutrient solution. Always defer to the current label if its directions differ.
When is it used?
It is presented for flowering-stage use, but the exact timing, crop and application method must follow the current approved label.
Can I use it on any crop?
No assumption should be made that it is suitable or legal for every crop. Confirm the intended crop and use against the current label before application.
Can I use it on food crops?
Only if the current approved label specifically authorises that crop and use. Do not apply it to edible crops based solely on general online advice.
Can it replace my base nutrients?
No. Bud Fast Part B is a plant growth regulator, not a complete fertiliser or base nutrient program.
Can I mix it with Part A or other additives?
Use combinations only when the current label or an authorised Nutrifield program expressly permits them. Do not create an unverified regulator mix.
How should I store it?
Keep it closed in the original labelled container in a cool, dry, well-ventilated area away from direct sunlight, children, food and waterways.
Where can I verify current Australian approval and directions?
Use the APVMA PubCRIS database and the product's current approved label. Registration and approved directions can change, so verify them before purchase or use.
