Welcome to your ultimate coco guide, tailor-made for those who work with soft water and use our BIG R.O. BASE. Here you get a clear, efficient plan – no guesswork. With our Just Mix & Grow technology, we make it easy to get the nutrient balance just right so you can focus on what matters most: harvesting big, tasty flowers. Follow this simple step-by-step guide and watch your coco cultivation go from standard to spectacular.


I. Pre-Soak & Early Growth (Week 0-1)

Products: BIG ROOTS, BIG R.O. BASE, BIG CALCIUM (BIG BOOST for premium) Just Mix & Grow-Tech: No complex schedules – mix the nutrients, water the plants and let them do the rest.

Preparation of coco:

  • Soak your coco in 2 mL/L BIG R.O. BASE, 2 mL/L BIG CALCIUM and 2 mL/L BIG ROOTS. This gives your seeds a perfect starting point with the right nutrient profile from the start.
    When the seeds germinate and the leaves appear, switch to a mild solution of 1 mL/L BIG R.O. BASE, 1 mL/L BIG CALCIUM, and 2 mL/L BIG ROOTS.

Pro Tip: Coco dries faster than soil. Lift the pot – if it’s still heavy, wait to water. Premium Pro Tip: Want extra speed? Add BIG BOOST (1 mL/L) to give your sprouts an early head start.

 


II. Vegetative Phase (Weeks 2-4)

Products: BIG R.O. BASE, BIG CALCIUM, BIG ROOTS (BIG BOOST, BIG SHIELD optional) Now the plants need to build strength and volume.

  • BIG R.O. BASE (2-3 mL/L) and BIG CALCIUM (2-3 mL/L) with every watering ensures a constant supply of vital nutrients. Remember: Coco doesn’t contain anything itself, so you’re in charge.
  • BIG ROOTS keeps the root system in top shape.

Water more often: Coco requires more frequent watering than soil. No complicated method – lift the pot, feel and then water. Remember no run-off with our “Just Mix & Grow” makes it easy, the plant eats it all!

Premium Pro Tip:

  • Add BIG BOOST (1 mL/L) for even stronger growth.
  • Have you experienced problems before? BIG SHIELD (1 mL/L) provides a protective layer to keep stress and pests at bay. Perfect for those who want complete control.

III. Transition to Flowering (Weeks 1-3 in Flowering)

Products: BIG R.O. BASE, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG BOOST, BIG SHIELD optional) Your plants now switch from green growth to flowering:

  • BIG R.O. BASE (3 mL/L) and BIG CALCIUM (3 mL/L) at every watering
  • BIG FLOWERS (1 mL/L ) to kick-start flowering at top speed.
  • BIG ROOTS continues to give to keep the root system in top shape and provide beneficial microorganisms

Pro Tip: Stick with BIG BOOST for the first weeks of flowering for a smooth transition. With coco, nutrient delivery is easy to control and “Just Mix & Grow” ensures you’re never left in the dark.


IV. Flowering phase (Week 4-6)

Products: BIG R.O. BASE, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG DIAMONDS, BIG BOOST, BIG SHIELD optional) Now it’s time for massive, dense flowers:

  • BIG R.O. BASE (approx. 3 mL/L ) gives plants the right nutrient profile.
  • BIG CALCIUM (3 mL/L) keeps health in check, while BIG FLOWERS (2 mL/L) increases flower size and density.

Premium additives:

  • BIG DIAMONDS (1 mL/L ) takes the quality level even higher.
  • BIG SHIELD (1 mL/L ) protects against stress so nothing disrupts the critical flowering phase.

Pro Tip: Let the coco dry out slightly between each watering – a simple but effective way to optimize flowering.


V. Late Flowering Phase (Week 7-8)

Products: BIG R.O. BASE, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG DIAMONDS, BIG BOOST, BIG SHIELD optional) It’s the final spurt: the plants invest all their energy in developing the flowers.

  • Continue with BIG R.O. BASE (2 mL/L) for stable nutrition.
  • BIG FLOWERS (3 mL/L) ensures maximum flower development, while BIG CALCIUM (2 mL/L) keeps them strong.

Premium Pro Tip:

  • BIG DIAMONDS (2-3 mL/L) adds the final luxury touch so you end up with shiny, trichome-rich top shoots.
  • BIG SHIELD (1-2 mL/L ) keeps enemies at bay when it matters most.

VI. Harvest & Flush (Week 9-10)

Products: BIG DIAMONDS (first flush week) and then clean water Now it’s time to polish the end result:

  • Use BIG DIAMONDS (2-3 mL/L) in the first flush week to give the flowers extra sparkle.
  • Then only clean water, so the plants consume the last of the nutrients themselves. Coco rinses easily and your flowers will be clean and tasty.

When is it time? When the leaves turn yellow and the colors change, the plants are nearing the finish line. Be patient – your reward will be aromatic, flavorful and potent.
