Description
A two-part base feed built for the way coco actually behaves
DualPart Coco Grow is the vegetative half of Terra Aquatica's two-part base feed for coco coir. Coco holds calcium and magnesium on its exchange sites and releases potassium in return, so a feed designed for rockwool runs into trouble in it. DualPart Coco is built with that exchange in mind, with the calcium and magnesium already balanced for the medium.
Key Benefits
- Formulated for coco's cation exchange - no separate CalMag needed in most tap water
- Two parts instead of three - a simpler mix than TriPart with the same control over the grow-to-bloom ratio
- Stable pH in the tank - holds its pH better through a recirculating run than a general-purpose feed
- Works run-to-waste or recirculating - dose the same either way, only the frequency changes
- Pairs with DualPart Coco Bloom - the ratio between the two shifts as the plant moves into flower
Coco that locks up calcium and drifts on pH
Fed the wrong nutrient, coco strips calcium and magnesium out of solution and hands back potassium, and the first sign is poor nutrient uptake with rusty spotting on the fan leaves. pH then wanders because the buffer is gone. A coco-specific base feed prevents the exchange from unbalancing the reservoir in the first place.
How to Use
- Early vegetative: 2 ml per litre of Grow with 1 ml per litre of Bloom
- Late vegetative: 3 ml per litre Grow, 1 to 2 ml per litre Bloom
- Transition: bring Grow down and Bloom up over the first fortnight of flower
- Mixing: Grow first into plain water, stir, then Bloom - never combine the concentrates
- Target pH: 5.8 to 6.2, EC to suit the plant's stage and your lighting
