Bonide Bontone II Rooting Powder

- Specializes in root development, helping cuttings establish faster in moist soil.
- Simple dip-and-plant use makes it suitable for beginners and quick projects.
- Best used for ornamentals, vegetables, fruit trees, and berries.
Caution: Avoid excessive dust inhalation and keep out of reach of children. It’s a rooting hormone product, so avoid mixing with incompatible products unless guided by instructions.

Best for: new gardeners or growers evaluating a full nutrient system. This trial-sized kit includes four formulas—Grow, Bloom, Boost, and Cal/Mag—enabling a complete grow cycle before committing to full-size containers.
- 4-part system covers root growth, flowering, transition support, and nutrient balance.
- Compatible with hydroponics, coco coir, rockwool, perlite, and soil.
- Simple, all-in-one evaluation for indoor and outdoor setups.
Limitation: As a trial set, it’s best viewed as a learning tool; results may vary with plant type and environmental conditions.
GS Plant Foods Cal-Mag 420 Dry

Buying Guide: Powder Nutrients Deep Dive
What to choose based on growth stage
Rooting powders, like Bonide Bontone II, are ideal for cuttings and transplants to encourage rapid root establishment. For ongoing nutrition, multi-formulas such as Lotus Intro Pack and Grow Pro Series provide complete feeding, while Cal-Mag products address calcium and magnesium needs that commonly limit growth in coco or filtered water systems.
Medium compatibility
Choose products labeled compatible with your medium. Hydroponics, coco coir, soil, and rockwool each respond differently to nutrient blends. The Lotus Grow Pro Series claims broad medium compatibility, while Cal-Mag 420 emphasizes soluble formulation for irrigation and foliar use.
Ease of use and scale
Consider your setup scale and experience. Ready-to-use rooting powders simplify propagation, while intro packs and multi-formulas reduce the number of bottles needed and simplify schedules for beginners and mid-size operations.
Safety and handling
Powder nutrients can irritate skin and eyes. Use protective gear when handling powders, follow label directions, and store in a cool, dry place. Keep out of reach of children and pets.
How to compare products quickly
- Identify whether you need rooting support, complete nutrition, or micronutrient supplementation.
- Check medium compatibility (soil, coco, hydro, etc.).
- Assess whether a single formula or a four-part system best fits your operation.
- Note application guidelines (dilution, frequency, and whether foliar use is supported).
FAQ
- Are powder nutrients safer than liquids? Powder forms often have longer shelf life and easier storage, but require accurate measurement and mixing with water for use.
- Can I use multiple powder products together? Yes, but ensure compatibility and avoid over-fertilization. Follow separate feeding schedules or use an integrated kit when available.
- What medium should I use Cal-Mag for? Cal-Mag 420 works well in coco coir and filtered water systems, and it can be used in irrigation or foliar spray.
- Is rooting powder essential for cuttings? It speeds root formation and improves uptake, but some cuttings may root without it depending on species and conditions.
- How often should I feed houseplants with powder nutrients? Start with a light schedule, monitor growth, and increase gradually as plants show steady growth and no signs of nutrient burn.
- Should I mix nutrients with every watering? Not always. Some products are designed for weekly feeding, while others are compatible with every watering regime. Follow product-specific instructions.
