BIG’s Guide to coco and hard water

Coco Growing Guide (Hard Water): From Seed to Full Yield with “Just Mix & Grow”
Introduction: Your shortcut to successful coco growing in hard water
Welcome to a no-nonsense coco guide, tailor-made for you with hard water. Here we replace the R.O. base with BIG GROW, BIG BLOOM and BIG CALCIUM as the solid foundation. Our “Just Mix & Grow” technology makes it easy to hit the perfect nutrient profile, so you can focus on growing healthy, vigorous plants and a harvest you can be proud of. Let’s get started.


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

Products: BIG ROOTS, BIG GROW, BIG CALCIUM Just Mix & Grow-Tech: Mix the nutrients, water and watch the magic unfold. Prepare the coco:
Before planting the seeds, soak your coco in a solution of 2 mL/L BIG GROW, 2 mL/L BIG CALCIUM & 2 mL/L BIG ROOTS. This ensures your seeds meet optimal conditions from day one – no empty calories, just pure nutrition. Seed germination and first growth:
When the seeds have germinated and the first leaves appear, switch to 1 mL/L BIG GROW, 1 mL/L BIG CALCIUM and 2 mL/L BIG ROOTS. This combination ensures strong roots and healthy, energetic plants from the start. Pro Tip: Coco dries faster than soil, so water a little more often, but without drowning the plants. Lift the pot – if it feels heavy, wait. Simple balance, no hocus pocus.


II. Vegetative Phase (Weeks 2-4)

Products: BIG GROW, BIG CALCIUM, BIG ROOTS (BIG BOOST, BIG SHIELD optional) It’s all about powerful growth:

  • BIG GROW (2-3 mL/L) and BIG CALCIUM (2-3 mL/L) with every watering ensures your plants get everything they need. Coco contains no nutrients on its own, so you’re in control.
  • BIG ROOTS continues to strengthen root formation so plants can absorb maximum nutrients and water.

More frequent watering: Unlike soil, coco requires more frequent watering. But no need to stress – with “Just Mix & Grow” it’s easy to dose correctly. Premium Pro Tip: Want a turbo growth? Add BIG BOOST (1 mL/L) to speed things up. Worried about stress and intruders? BIG SHIELD (1 mL/L) keeps plants ready for defense.


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

Products: BIG BLOOM, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG BOOST, BIG SHIELD optional) Now your plants switch from pure leaf growth to flower production:

  • Reduce BIG GROW and introduce BIG BLOOM (3-4 mL/L) to provide the phosphorus- and potassium-rich nutrients that boost bud formation.
  • BIG FLOWERS (1 mL/L) ensures a stable start to flowering, while BIG CALCIUM (3-4 mL/L) continues to keep plants strong.

Pro Tip: Keep the coco moist but well-drained. Stability is key and “Just Mix & Grow” makes nutrient balance easy to maintain.


IV. Flowering phase (Week 4-6)

Products: BIG BLOOM, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG DIAMONDS, BIG BOOST, BIG SHIELD optional) Now it’s all about heavy, dense flowers:

  • BIG BLOOM (3 mL/L) provides a robust nutritional foundation.
  • BIG CALCIUM (3 mL/L ) keeps plants healthy as they push to flower.
  • Turn up the BIG FLOWERS (2 mL/L) to ensure a massive flower yield.

Premium additives:

  • BIG DIAMONDS maximizes resin production and quality.
  • Keep stress down with BIG SHIELD and power up with BIG BOOST.

Pro Tip: Allow the coco to dry out slightly between watering to optimize absorption and flower development.


V. Late Flowering Phase (Week 7-8)

Products: BIG BLOOM, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (BIG DIAMONDS, BIG BOOST, BIG SHIELD optional) Final push towards a top-class harvest:

  • Turn down the BIG BLOOM (2 mL/L) slightly, but turn up the BIG FLOWERS (3 mL/L) to get the last nutrient packet into the flowers.
  • BIG CALCIUM (2 mL/L ) keeps plants strong while they prepare for finals.

Premium Pro Tip:

  • BIG DIAMONDS (3 mL/L) provides crystal sparkling top shots of the best quality.
  • BIG SHIELD prevents stress in the crucial weeks.

VI. Harvest & Flush (Week 9-10)

Products: BIG DIAMONDS and water Now it’s time to fine-tune the final:

  • Use BIG DIAMONDS (3 mL/L) for the first flush week and then only clean water. This will make your flowers sparkle and give a clean, aromatic finish.
  • Coco rinses easily, so take advantage of it. Wait patiently until the plants show signs of maturity: yellowing leaves and beautiful color changes.

Final Tip: Patience pays off. Your reward is a premium harvest with top taste, aroma and potency.
