Mills C4 250 ml
Mills C4 250 ml is the highly concentrated bloom stimulator from Mills Nutrients engineered to trigger early flower sets and maximise flower development. The formula contains a complex blend of sugars, vitamins, amino acids and humic acids that facilitate carbohydrate delivery to flowering sites and promote the production of complex essential oils. At dosages of just 0.5 to 1.5 ml per litre, this compact format yields hundreds of litres of feed solution. The efficient entry point for growers evaluating a professional-grade bloom stimulator.
Mills C4 250 ml – High-Concentration Bloom Stimulator for Explosive Flower Development
Flower quality and weight are determined by what happens during the bloom phase. Mills C4 is the bloom stimulator in the Mills Nutrients programme, designed to unlock the full flowering potential of your plants through enhanced carbohydrate delivery and essential oil biosynthesis. Its extreme concentration means minimal input for maximum output.
Multi-Target Formulation
Unlike single-compound bloom boosters, C4 operates across multiple metabolic pathways simultaneously. This broad-spectrum approach delivers compounding benefits that narrow-focus products cannot match:
- Sugars and carbohydrates: direct energy substrates for flowering metabolism and rhizosphere microbiome nutrition.
- Amino acids: protein precursors essential for cell division and enzyme production during flower formation.
- Humic acids: improve cation exchange capacity and optimise nutrient uptake efficiency in the root zone.
- Vitamins: metabolic cofactors supporting terpene and essential oil biosynthesis pathways.
Application Protocol
Add 0.5 ml per litre from week 2 of flowering, increasing progressively to 1.5 ml per litre in later bloom weeks. C4 pairs with Mills Basis A&B as the continuous base nutrient. Finish the programme with Mills Ultimate PK for targeted phosphorus and potassium supplementation in the final weeks.
250 ml Format Efficiency
At 0.5 ml/L starting dosage, 250 ml of C4 produces up to 500 litres of feed solution. Even at maximum dosage, output exceeds 166 litres. This format is ideal for smaller setups or for growers trialling C4 before committing to larger volumes. During the vegetative phase, pair with Mills Start-R for seamless programme continuity into bloom.

What is the recommended dosage for Mills C4?
Apply 0.5 ml per litre from week 2 of flowering, gradually increasing to 1.5 ml per litre during later bloom stages. Consult the Mills growth chart for precise weekly dosage adjustments.
When should I start using C4 in the flowering cycle?
Introduce C4 from week 2 of the flowering period. During week 1 of bloom, continue with Basis A&B and Start-R only. From week 2 onwards, C4 actively stimulates flower formation and carbohydrate transport.
What is the difference between Mills C4 and Mills Ultimate PK?
C4 is a bloom stimulator that promotes early flower formation and carbohydrate transport. Ultimate PK is a PK booster that delivers additional phosphorus and potassium during the final weeks for weight and density. They are complementary products used at different stages of the flowering cycle.
How does C4 affect essential oil and terpene production?
C4 contains vitamins and amino acids that serve as metabolic cofactors and precursors in the biosynthesis of terpenes and essential oils. Growers consistently report more intense and complex aromatic profiles when integrating C4 into their bloom programme.
