ATAMI Fertilizers: The Dutch Nutritional Standard for Your Indoor Grows

ATAMI is Dutch expertise serving your plants for over 25 years. This Dutch brand has established itself as a global benchmark with its B'Cuzz, Bloombastic, and ATA Organics ranges. Whether you're growing in coco, hydroponics, or soil, ATAMI offers nutritional solutions adapted to each substrate and every development phase.

Why choose ATAMI fertilizers for your indoor grow

ATAMI's strength lies in its constant research and balanced formulations. Their fertilizers are specifically developed to meet the precise nutritional needs of each phase: explosive growth with nitrogen-rich NPKs, generous flowering thanks to ultra-concentrated phosphorus and potassium boosters. The B'Cuzz range, for example, offers complete nutrition with perfectly calibrated NPK ratios to maximize yields without risking over-fertilization.

What truly sets ATAMI apart is the versatility of its products. Their formulations work equally well in organic cultivation and intensive hydroponics. The famous Bloombastic alone combines the functions of several classic additives, with a PK 20-21 ratio that boosts resin production and bud density. Honestly, when you see the difference in the last few weeks of flowering, you understand why so many growers swear by this brand.

How to choose your ATAMI fertilizers based on your setup

To start with ATAMI, you first need to identify your substrate. For coco, the B'Cuzz Coco range offers an NPK base adapted to the inertness of this substrate, with chelated trace elements for optimal absorption. In hydroponics, B'Cuzz Hydro offers a more concentrated formulation that takes into account constant nutrient circulation. For soil, ATA Organics relies on plant extracts and humic acids that stimulate microbial life in the soil.

Dosage varies by phase: 1-2ml/L during growth, up to 4ml/L during flowering for nutrient bases. Boosters like Bloombastic are used at 0.5-1.5ml/L only at the end of flowering, during the last 4-6 weeks. The trick with ATAMI is to follow their grow schedule, which precisely indicates target ECs: 1.2-1.6 during growth, 1.8-2.2 during flowering depending on the varieties.

Frequently asked questions about ATAMI fertilizers

Which ATAMI fertilizer to choose for indoor coco cultivation?

For coco, the B'Cuzz Coco range is specially formulated for this substrate. Use B'Cuzz Coco A+B as a nutrient base (2-4ml/L depending on the phase), supplemented by B'Cuzz Root Stimulator at the beginning of the cycle (1ml/L) to develop the root system. During flowering, add B'Cuzz Bloom Stimulator (1-2ml/L) and finish with Bloombastic (0.5-1.5ml/L) in the last few weeks. This combination perfectly exploits the properties of coco while avoiding the typical calcium-magnesium deficiencies of this substrate.

How to dose ATAMI fertilizers without risking burning the leaves?

The secret with ATAMI is to start with reduced dosages and gradually increase them according to the plants' reaction. Start at 50% of the recommended doses, then gradually increase while monitoring the EC of your nutrient solution. Never exceed EC 1.6 during growth and EC 2.2 during flowering, even with hungry varieties. If you see leaf tips yellowing or browning, it's a sign of over-fertilization: rinse immediately with clear water and resume with lower doses. Since ATAMI is concentrated, it's better to under-dose than over-dose.

Which ATAMI products to combine for the entire growth and flowering cycle?

A complete ATAMI cycle starts with B'Cuzz Root Stimulator (weeks 1-3) to establish a strong root system, followed by the A+B base adapted to your substrate (throughout the cycle). During growth, add B'Cuzz Growth Stimulator to boost vegetative development. As soon as you switch to 12/12, switch to B'Cuzz Bloom Stimulator, which promotes the formation of flowering sites. For the last 4-6 weeks, incorporate Bloombastic, which advantageously replaces several classic PK additives. Finish with a flush with clear water or with B'Cuzz Silic Boost, which strengthens plant tissues.

Are ATAMI fertilizers like B'Cuzz compatible with hydroponics?

Absolutely, ATAMI even offers a specific B'Cuzz Hydro range designed for hydroponic systems. These formulations take into account the recirculation of nutrient solutions and the absence of a buffer substrate. Solubility is optimized to prevent precipitation in reservoirs, even with hard water. In hydro, strictly follow the dosages because plants absorb directly without substrate filtering. Change your solution every 1-2 weeks and regularly clean your systems to prevent the accumulation of mineral salts.

How to follow the ATAMI grow schedule to adjust pH and EC?

The ATAMI chart indicates precise target EC values: 0.8-1.2 at the beginning of growth, 1.2-1.6 during established growth, then 1.6-2.2 during flowering depending on your varieties' appetite. For pH, aim for 5.8-6.2 in hydro/coco and 6.0-6.5 in soil. Always measure after mixing all your additives, as some ATAMI products naturally lower the pH. If your EC exceeds the recommendations, dilute with water rather than reducing fertilizer doses. Adjust the pH last with pH- or pH+ as needed, checking 30 minutes after each correction.
