Mills C4 1 l
Mills C4 1 litre is the professional-volume format of the highly concentrated bloom stimulator from Mills Nutrients, engineered for growers managing large plant counts or running multiple flowering cycles per year. The proprietary blend of sugars, vitamins, amino acids and humic acids drives carbohydrate transport to flowering sites and stimulates essential oil biosynthesis. At 0.5 to 1.5 ml per litre dosage, one litre of C4 produces hundreds to over 2000 litres of feed solution. Maximum bloom efficiency at minimum per-dose cost.
Mills C4 1 Litre – Professional Volume for Maximum Bloom ROI
At scale, bloom stimulator cost per harvest becomes a significant line item. Mills C4 1 litre is the largest single-unit format of the bloom stimulator in the Mills Nutrients programme, delivering the lowest cost per dosage across the entire C4 range. For operations running concurrent flowering rooms or sequential cycles, this format eliminates mid-season procurement interruptions.
Biochemical Mode of Action
C4 targets two critical metabolic processes during the reproductive phase. First, it accelerates photoassimilate translocation — the movement of sugars produced by photosynthesis from leaves to developing flowers. Second, it upregulates secondary metabolite biosynthesis, driving the production of terpenes, flavonoids and essential oils that determine harvest quality beyond simple weight metrics. This dual-axis approach produces compounding results that single-target products cannot replicate.
1 Litre Format Economics
- Lowest cost per dose: the most economical format in the C4 range for regular users.
- Exceptional yield: at 0.5 ml/L starting dosage, one litre produces up to 2000 litres of feed solution.
- Multi-cycle coverage: a single purchase sustains multiple complete flowering cycles without reordering.
Complete Mills Flowering Programme
C4 takes over from Mills Start-R as plants enter the flowering phase. Apply 0.5 ml/L from week 2, increasing to 1.5 ml/L during peak bloom. Mills Basis A&B continues as the base nutrient throughout. In the final weeks, add Mills Ultimate PK for targeted P&K delivery to maximise fruit density and final harvest weight.

How many litres of feed solution does 1 litre of Mills C4 produce?
At the starting dosage of 0.5 ml per litre, one litre of C4 yields up to 2000 litres of nutrient solution. At maximum dosage of 1.5 ml per litre, output exceeds 660 litres. The extreme concentration makes C4 one of the most efficient bloom stimulators available.
When do I transition from Mills Start-R to C4?
Start-R is used through week 2 of flowering. C4 is introduced from week 2, creating a brief overlap period. From week 3 onwards, the feeding programme runs on Basis A&B plus C4, with Ultimate PK added in the final weeks.
Is the 1 litre format more cost-effective than smaller sizes?
The 1 litre format offers the lowest per-millilitre cost in the C4 range. For growers using C4 consistently across multiple cycles, the savings versus 250 ml and 500 ml formats are substantial over a growing season.
Does Mills C4 work in hydroponic systems?
C4 is fully compatible with all hydroponic configurations including drip, NFT, DWC and ebb and flow systems. The formula is completely soluble and does not cause blockages in pumps, emitters or recirculating systems.
