GOOD QUESTIONS. CLEAR ANSWERS.
New grow. No guesswork.
Which pack is right for me?
Both packs share the same root, veg and flower foundation. Choose PK 9/18 for the PK programme, or Resin for the flavour and resin-focused programme. Your stockist can help you choose.
Can I combine PK 9/18 and Resin?
No. These are alternative programmes. Stick to one and follow its matching feed chart.
Can I use it in coco, soil or hydro?
The Monkey range is designed for coco, soil and hydro. Coco, soft water and RO water may also need Mag Cal, which is not included in the starter pack. Ask your stockist for its confirmed dose.
Do I need any other equipment?
This is a nutrient starter pack, not a complete growing setup. Choose your medium, containers, lighting and measuring equipment with your stockist to suit your grow.
How much should I use?
Follow the feed chart and bottle labels. The calculator scales amounts to your reservoir volume. Root Shoot uses 2 ml per 10 L in veg weeks 1–2, then 3 ml per 10 L through bloom week 5.
Where can I buy a starter pack?
Available from your stockist. Use the stockist finder or contact Team Monkey for current availability.
