Description
Algae-based root stimulation for faster-striking cuttings
Canna Rhizotonic is an algae-based vegetative root stimulator packed with over 60 microbiological substances, trace elements and hormones that drive new root growth in cuttings and potted plants. Used mainly as a foliar spray, it helps cuttings root quickly and with less stress, and doubles as a reservoir tonic for established plants. It's alkaline-based, so it raises the pH of your solution — check and re-adjust after adding.
Key Benefits
- 60+ microbiological substances, trace elements and hormones to stimulate new roots
- Faster, healthier rooting with less transplant stress
- Doubles as a general health tonic for established plants
- Works with most substrates and hydroponic systems without adverse effect
Slow-striking cuttings and transplant shock
Cuttings that are slow to root, or plants sulking after being potted on, lack the root-zone activity needed to establish. Rhizotonic's hormones and microbiological blend push new root development while easing stress, so cuttings take and plants recover faster.
How to Use
- Foliar spray (cuttings / early growth): 4ml per litre, applied 1-6 times daily during early development
- Reservoir tonic (established plants): CANNA taper the root feed — 4ml per litre for the first dose and after every re-pot, 2ml per litre through vegetative growth, then 0.5ml per litre once flowering starts
- pH: alkaline-based — check and re-adjust reservoir pH after adding
