Foliar Spraying with CANNA Rhizotonic

CANNA Rhizotonic is a powerful root stimulator containing a blend of natural algae extracts and vitamins. While primarily used as a root drench, foliar application can deliver rapid results — especially during transplant stress, early vegetative growth, and recovery from environmental shock.

What is CANNA Rhizotonic?

Rhizotonic is a 100% natural product based on algae extracts that stimulates root development, increases resistance to disease, and accelerates recovery after transplanting. It contains over 60 microbiological elements that promote vigorous root growth.

Benefits of Foliar Spraying

When applied as a foliar spray, Rhizotonic is absorbed directly through the leaf surface (stomata), bypassing the root system entirely. This is particularly useful when:

Roots are damaged or underdeveloped (cuttings, transplants)
The plant is under stress (heat, overwatering, nutrient lockout)
You want to accelerate early vegetative growth
Plants need a quick boost of vitality

How to Foliar Spray with Rhizotonic

Dilution rate: 40 ml per 10 liters of water (4 ml/L)

Procedure:

Mix Rhizotonic with clean, pH-adjusted water (pH 5.8–6.2)
Use a fine mist sprayer for even coverage
Spray the undersides of leaves (where stomata are most concentrated)
Apply during lights-off or early morning/late evening to prevent light burn
Do not spray during flowering — focus on vegetative phase and cloning

Frequency: 1–3 times per week during the first 1–2 weeks after transplant or when stress symptoms appear.

Key Tips

Always spray when lights are off to avoid leaf burn
Combine foliar application with root drenching for maximum effect
Rhizotonic is compatible with all CANNA nutrient lines (Terra, Coco, Aqua, Hydro)
Store in a cool, dark place; use diluted solution within 24 hours

When NOT to Foliar Spray

During the flowering/bloom phase (risk of mold on buds)
Under intense HPS/LED lighting
If the grow room humidity is already above 70%

Note: CANNA Rhizotonic is available at authorized retailers including AZ Growshop Thailand.
