If you are looking for flowers and fruits hard as a rock, look no further, Rokzbastic does the job! This new Bastic member is designed to take your final harvest to the top. Read more about our new blooming product.

The Atami Rokzbastic product family formulated to boost flowering, enhance root strength, and improve plant performance.

Finding the right blooming product for your plant species or variety can be tough, especially with so many options on the market. We are aware of this.

So, what makes Rokzbastic – our latest flowering product – different from other flowering products? What was the vision behind Rokzbastic?

The idea was to bring a fertilizer for the flowering phase that would help growers produce even bigger, denser and brighter crops. With this goal in mind, Rokzbastic was created.

Atami Rokzbastic bottles in 100ml and 5.5L sizes, powerful nutrient formula for dense, high-quality flowering plants.

What sets Rokzbastic apart is its unique PK value of 10-20, which corresponds to a P:K ratio of 1:2. This high concentration of potassium makes it ideal for plants with long blooms or those that require a higher amount of potassium than phosphorus. It is also perfect to use it at the end of the flowering phase and during maturation to achieve a heavier and firmer final harvest.

But Rokzbastic has much more to offer than a high potassium concentration. It has been enriched with 1% iron and other essential minerals that plants need to carry out vital processes. And due to our unique blending techniques, we are able to provide a complete finishing cocktail for your crops.

For the best results, use Rokzbastic during the last weeks of flowering in combination with your basic nutrients.

If you really want to boost the stimulating effect during this phase, you can also use it in combination with Bloombastic. However, be careful when mixing these high PK products as you run the risk of over-fertilising your plants. To avoid this, it is recommended to use Rokzbastic right after Bloombastic during the last weeks of flowering to maximize the effects of both products.

Don’t just take our word for it, Rokzbastic, like other Atami fertilizers, has won an international award for its quality and effectiveness. It already received a lot of positive reviews and good feedback from users who have tried it. With Rokzbastic, you can achieve rokz-solid and frosty results, enjoying a bountiful harvest plenty of natural flavours and aromas. Give it a try and see the difference for yourself!

Frequently Asked Questions About Optimising Flowering with Rokzbastic

Rokzbastic is a premium finishing bloom additive designed to give “rock-solid and frosty” results. Meaning firmer, heavier and more compact flowers and fruits.

The product stands out with a unique PK value of 10-20 (phosphorus:potassium ratio of 1:2), a high potassium concentration that supports plants with longer flowering phases or higher potassium needs.

Rokzbastic is intended for use during the final 4 to 6 weeks of the flowering phase, the fruiting and ripening stage, alongside your base nutrients.

It is suitable for various media. Soil, coco, hydroponics. And works in manual or automatic irrigation systems, making it versatile across different setups.

The recommended dose is 0.5–1 ml per litre of water. Because of its high PK value, you must monitor your nutrient solution’s EC to avoid over-fertilisation when using Rokzbastic (especially if combined with other high-PK products).

Yes, using Rokzbastic right after Bloombastic can enhance the stimulating effect of the flowering phase, increasing yield, flavour and aroma. However, combining such products requires caution regarding EC levels.

It’s especially suited for plants with long flowering periods or high potassium needs. For example: bell peppers, chillies, citrus fruits, red tomatoes, and large-flower ornamentals like hibiscus or roses.

Apart from the high P:K ratio, Rokzbastic is enriched with around 1 % iron and other essential trace elements, while being low in ballast substances (like sodium and chlorine) for cleaner nutrition.

It addresses the challenge of achieving denser, heavier and compact flowers. Particularly for growers struggling with weak flower structure or inadequate finishing. It also helps in simplifying the final-stage nutrient strategy when used correctly.

For maximum impact, use Rokzbastic during the last 4–6 weeks of flowering, use the correct dosage (0.5–1 ml /L), monitor EC levels, and if desired combine with Bloombastic. Along with a base nutrient plan, this approach can lead to significantly firmer, heavier, and frosty blooms.
