Shipping is FREE from €45 to mainland Spain and continental European Union. Below that amount, and for other destinations (islands, overseas territories or outside the EU), the exact cost is calculated automatically in the cart before you pay, with no surprises.

We ship all orders with DHL Express. Delivery usually takes 1-2 working days in mainland Spain and 2-5 working days in the rest of Europe. Orders placed before 14:00 (Spanish time) normally leave the same day (except holidays or incidents).

When your parcel leaves our warehouse, DHL sends you an email with the tracking number and keeps you updated at every step: delivery, collection point or delivered. If you don't receive it, check your spam folder and make sure the email on your order is correct.

The Kit Growth Basic is the easiest starting point: it includes Growth Accelerator, Sweet Lolita and Jamaican Bloom to cover growth, nutrition and flowering. It comes in 250 ml, 500 ml, 1 L or 5 L bottles. Always start with the minimum dose on the label.

Jamaican Bloom is our base fertiliser for flowering: it provides the phosphorus and potassium your plant needs to form more flowers. For the final bulking stage, combine it with Bazooka Bloom K30. Follow the dose on the label and increase it gradually.

Bazooka Bloom K30 is our high-potassium product for bulking and ripening. Dose: 1-2 ml per litre, always starting with 1 ml/L and increasing only if the plant responds well.

Bone & Muscle is our calcium and magnesium corrector. Dose: 1-3 ml per litre. It is useful with soft or mineral-poor water, or when deficiency symptoms appear. Before correcting, rule out overwatering or pH out of range.

LaCalva is designed as nutritional support during cycle changes and stressful situations (heat, transplanting…). Dose: 1-2 ml per litre, starting with 1 ml/L. First correct the cause of the stress: watering, temperature and light.

The Kit Growth Basic contains Growth Accelerator, Sweet Lolita and Jamaican Bloom. The Kit Premium Plus adds LaCalva, Caribbean Algae, Bazooka Bloom K30, Flower Karma, Thrycho Killer and Amino Canna. Choose Basic to keep it simple and Premium Plus to cover every stage of your grow.

Multiply the dose on the label (ml per litre) by the litres of water you are preparing. Example: 1 ml/L for 5 litres = 5 ml. Measure with a clean syringe or measuring cup, shake the bottle before use and only prepare the water you will use.

Yes, they can be applied together in the same watering. Do it like this: fill the tank with water first and add the products one by one, stirring well after each one and starting with low doses. Never mix the concentrates directly with each other. If you adjust the pH, measure it at the end.

Yes, most can be used indoors and outdoors. The dose also depends on light, temperature, substrate and pot size: start with the minimum on the label and adjust little by little. Outdoors, keep the bottles in the shade.

Yellow leaves can be caused by over- or underwatering, nutrient deficiency or excess, pH out of range, damaged roots or too little light. Don't add fertiliser without knowing the cause: check moisture, drainage and whether it's the new or the old leaves turning yellow. Send photos to Amanda in the chat and she will help you find the reason.

If the substrate stays wet for a long time and the plant has drooping or yellow leaves and grows slowly, you are probably overwatering. Wait until the pot feels lighter before watering again and check that it drains well. Don't try to compensate with more fertiliser.

Soft leaves, dry substrate and a very light pot mean lack of water. Water slowly until the whole substrate is evenly moist, without increasing the fertiliser dose, and avoid alternating extreme dryness with waterlogging.

Potassium Soap is used to clean and care for leaves and stems. Dilute it well according to the label and apply it when the plant is not in direct light, without wetting the flowers. Test it on a small area first and don't use it in intense heat.

Store them closed, upright, in a cool, dry place away from direct light, out of reach of children. Don't transfer them to other bottles and always keep the label.

Well closed and stored, our products last up to 3 years, even after opening. Heat, direct light or putting dirty utensils in the bottle can shorten their life. Close the cap right after measuring the dose.
