VitaLink Coir Classic Bloom 5L Hard Water

Bloom nutrition built for hard-water coco growing

VitaLink Coir Classic Bloom Hard Water is a one-part flowering nutrient formulated specifically for plants grown in coco and coir where the tap water is naturally mineral-rich. It delivers balanced macro and micronutrients through the bloom stage to build larger flowers, stronger bud density and a more reliable harvest. Growers on hard water routinely fight nutrient imbalances that standard feeds don't account for; this formula is built around that mineral content rather than against it, helping avoid the nutrient lockout that leads to weak, airy buds.

Key Benefits

• One-part bloom feed designed specifically for coco and coir substrates
• Hard-water formulation that works with naturally mineral-rich supplies
• Humic and fulvic acids improve nutrient uptake and root-zone availability
• Vitamin B1 supports root health and stress recovery in the grow room
• Simple feeding programme with no complex multi-part schedule
• Stronger flowering with improved bud density, flavour and aroma

Getting airy buds or poor flowering from hard tap water?

Feeding coco with hard tap water often causes nutrient imbalances and poor uptake, leaving plants with weak flowering and loose, airy buds. Coir Classic Bloom keeps the nutrient solution balanced against that background mineral load, so plants put their energy into flower formation instead of fighting lockout, giving healthier plants and more consistent yields from coco-based systems.

How to Use

• Shake well before use.
• Add to water and mix thoroughly before feeding.
• Use throughout the flowering stage when growing in coco or coir.
• Adjust feeding strength to plant size and stage of bloom.
• Maintain a nutrient solution pH between 5.8 and 6.5 for optimal uptake.
• Suitable for hand-watering, drip irrigation and automated hydroponic systems.
