A Soil-Specific Boost for Heavier, Denser Blooms
Hydrotops Solo Soil Boost is a 100% organic flowering booster developed specifically for plants grown in soil and compost. Designed to run alongside Hydrotops Solo Bloom, it supplies additional phosphorus, potassium and naturally derived bio-stimulants through the most demanding weeks of the bloom stage. The pH-balanced formula improves nutrient uptake, supports flower development and helps produce denser, heavier blooms with better aroma and flavour. It's suitable for bio-organic growing in a grow tent, grow room or greenhouse.
Key Benefits
- 100% organic flowering booster built for soil-grown plants
- Suitable for bio-organic growing and greenhouse cultivation
- More flowering sites and improved bud density during bloom
- Efficient nutrient uptake for higher final yield and quality
- Enhanced flavour and aroma from natural bio-stimulants
- pH-balanced formula that complements Solo Bloom for consistent feeding
Fixing Airy Buds and Slow Flower Development in Soil
As flowering advances, plants need more phosphorus and potassium to fuel heavy flower production. Without extra support you get airy buds, poor bud density, reduced yield and slower development. Solo Soil Boost delivers targeted organic nutrition during this critical window, helping soil-grown plants channel more energy into larger, denser flowers while staying healthy.
How to Use
- Programme: Use alongside your regular Hydrotops Solo Bloom feed.
- Start: Begin from week 3 of flowering.
- Dose: 0.5-2ml per litre of water, starting low and increasing as bloom progresses.
- Duration: Continue to around week 6, or longer for extended-flowering varieties.
- Frequency: Use with every watering during the application period.
- Tips: Shake well before use and monitor EC and pH to hold optimum conditions.
