Yes. Berkana is a full-cycle formula covering growth and bloom. You do not need a separate base nutrient, root stimulator, bloom booster, PK enhancer, or CalMag. One product. Every stage.

No. Berkana is a mineral-based dry nutrient formula. It contains chelated trace elements, which are synthetic chelation agents used to keep minerals available across a wide pH range. It also contains organic components: humic acid, fulvic acid, and seaweed extract, but it is not a certified organic product.

If you need a 100% organic option, Jera is fully organic and biodegradable.

NPK 10–30–20 with 2% magnesium oxide. Chelated iron, manganese, zinc, copper, boron, and molybdate. Humic acid, fulvic acid, and seaweed extract (Macrocystis P). Formulated in the Netherlands. Tested by Nutricontrol (heavy metals, pathogens) and Eurofins Agro (minerals, carbon).

Up to 90% more concentrated. A 1000g bag of Berkana goes significantly further than an equivalent volume of liquid nutrient.

At the recommended dose for a standard setup, a 1000g bag covers approximately 13 full grows at average consumption. Cost per serving at 1000g is €0.079.

Add the measured amount of Berkana directly to your water. Stir for five minutes until fully dissolved. Berkana is 100% water-soluble, no sediment, no residue.

For hydroponics, aeroponics, or mistponics: stir twice with a 45-minute pause between additions.

It depends on your growing medium and growth stage. See the Schedule page for the full dosing table by stage and medium.

The general range is 2–5g per litre of water, moving from the lower end in early growth to the higher end through bloom.

Usually not. Berkana is pH-buffered and works within a range of 5.5 – 7.5 without manual adjustment.

Soil: ideally 6.0 – 7.0. Coco and hydro: ideally 5.5 – 6.5.

If your pH is drifting consistently outside these ranges, check your source water. High bicarbonate content in hard water is the most common cause.

Yes, Berkana works in soil, coco, rock wool, hydroponics, aeroponics, and mistponics. The dose and EC target differ by medium. See the Schedule page.

You can, but you do not need to. Berkana was formulated to replace other nutrients, not to be stacked with them. Adding other products alongside Berkana risks overdosing on specific elements and complicates your setup.

If you have a specific deficiency that Berkana alone is not covering, contact us before adding anything.

Yes. Start at the lower end of the dose range during the seedling and early vegetative phase. Increase as the plant develops.

Most growers using Berkana in soil or coco will not need Jera. Jera is relevant in two situations: you are running an organic grow without Berkana, or you want to use a dedicated flush product in the final week before harvest. Outside of these situations, Berkana covers everything Jera offers.

Most growers will not need Uruz. Uruz is specifically for high-intensity water-based systems, hydroponics, aeroponics, mistponics, where calcium demand outpaces what Berkana alone can supply. If you are growing in soil or coco at normal intensity, Berkana covers your calcium requirements.

Yes. They are compatible. Jera and Uruz are both 100% water-soluble and will not interact negatively with Berkana or with each other.
