A Two-Part Base Built on Chelated Minerals
Emerald Harvest Cali Pro is a two-part base feed available as Grow for veg and Bloom for flower, both built on high-grade chelated mineral nutrients that stay available across the pH range roots actually work in. Emerald Harvest come straight from California, home to some of the world's biggest and best growers, and the range has built a serious following for one simple reason: it delivers. Splitting the feed into an A and a B keeps calcium apart from sulphates and phosphates in concentrate, which stops the precipitation single-part feeds suffer when pushed hard.
Key Benefits
- Two-part A and B format keeps antagonistic elements apart until they hit the tank
- Grow and Bloom versions, so the ratio matches the stage rather than one bottle doing both jobs
- High-grade chelated minerals for reliable, clean uptake
- A complete base, so boosters sit on top rather than filling gaps
- Five sizes from a 0.95 litre tent bottle to a 22.71 litre commercial drum
Nutrient Lock-Out When You Push Hard
Demand peaks in late veg and through bloom, and that is exactly where feeds start falling over. Push a single-part hard and calcium reacts with phosphate and sulphate in the tank, so what reaches the roots is not what you measured out. The plant shows it as slow growth and poor uptake, finishing as airy flower and low yield. Keeping A and B apart until dilution keeps every element available.
How to Use
- All media: add part A to your water and stir, then add part B and stir again — never mix the concentrates together
- Equal parts: dose A and B in equal measure, following the Cali Pro feed chart for your week
- Grow through veg, switching to Bloom as flowering sets in
- Check pH after mixing — around 5.5-6.5 in hydro and coco, a touch higher in soil
- Mix fresh and keep the tank moving
