Soil growing guide: From seed to full yield – simple, effective and unbeatable

Introduction: Your direct route to a successful harvest
Welcome to the ultimate soil growing guide – a simple, proven recipe for turning your seeds into a lush, juicy yield you can be proud of. Our new product line, combined with our smart “Just Mix & Grow” technology, makes it easy for you to achieve top-class results from start to finish.
Even if you’re used to our previous products, this guide will help you navigate seamlessly to our new system. And don’t worry: the familiar, impressive results are still there – it’s just easier and more efficient.
Let’s jump straight into how our nutrients and additives help you build strong roots, lush plants and powerful flowers. You’ll get a streamlined and practical plan that ensures maximum yield, every time.


1. Seed germination and Early Growth (Week 0-1)

Products: BIG ROOTS, BIG GROW, BIG CALCIUM (and BIG BOOST for premium) Just Mix & Grow Tip: Mix nutrients in the water, water your plants – and watch them thrive. No complicated technique, just mix & grow. From seed to life: When the seeds sprout and the first leaves appear, it’s time to give your little sprouts a nutrient-rich start.

  • BIG ROOTS (2 mL/L): An early focus on root formation ensures strong, deep roots from the very beginning.
  • BIG GROW (1 mL/L) & BIG CALCIUM (1 mL/L): When the first, “real” leaves appear, boost growth and cell building so plants are strong from the start.
    Pro Tip: Avoid overwatering – the soil retains moisture, so let the surface dry slightly before watering again.
    Premium Pro Tip: Add BIG BOOST (1 mL/L) to give your sprouts extra strength and resilience from day one.

2. Vegetative Phase (Week 2-4)

Products: BIG GROW, BIG CALCIUM, BIG ROOTS (and BIG BOOST, BIG SHIELD for premium)
Now it’s all about solid building: You want strong, robust plants with lots of leaf growth.

  • BIG GROW (2-4 mL/L) for intense green growth.
  • BIG CALCIUM (2 mL/L) for strong cell walls and prevention of nutrient deficiencies. Water with care: Rather a thorough watering infrequently than splashing all the time. The soil must be able to drain and nutrients are added with every watering. Premium Pro Tip: Want extra speed for growth? Add BIG BOOST (1 mL/L). And if you’ve had problems in the past, take no chances: add BIG SHIELD (1 mL/L ) to keep plants healthy and stress-free.

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

Products: BIG BLOOM, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (+ BIG BOOST, BIG SHIELD optional)
Plants now go from vegetative growth to flower development.

  • Turn down BIG GROW and switch to BIG BLOOM (3-4 mL/L) to provide plenty of phosphorus and potassium for flower formation.
  • BIG FLOWERS (1 mL/L ) boosts flowering from the start.
    Pro Tip: Continue with BIG BOOST for the first few weeks of flowering for a smooth transition and a kickstart to flower development.

4. Flowering phase (Week 4-6)

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

  • BIG BLOOM (3 mL/L) provides the nutrition needed for maximum flowering.
  • BIG CALCIUM (1 mL/L) keeps plants healthy and prevents nutrient deficiencies.
    Premium Additives:
  • BIG DIAMONDS (1 mL/L) to increase flower density and resin production.
  • BIG SHIELD (1 mL/L ) to protect against stress and keep plants in top shape. Pro Tip: Beware of overwatering. Let the soil dry out slightly between watering to allow roots to thrive and flowers to develop optimally.

5. Late flowering phase (Week 7-8)

Products: BIG BLOOM, BIG CALCIUM, BIG FLOWERS, BIG ROOTS (+ BIG DIAMONDS, BIG SHIELD, BIG BOOST optional)
It’s the final sprint:

  • Continue with BIG BLOOM (3 mL/L) to support the final growth spurt.
  • Keep plants healthy with BIG CALCIUM (1 mL/L) so they can perform at their peak right to the end.
    Premium Additives:
  • BIG DIAMONDS: Provides extra crystals so your flowers sparkle with optimal aroma and strength.
  • BIG SHIELD: Keeps pests and stress at bay when it really matters. Pro Tip: Balance all factors – water, light and nutrition. You’ll soon reap the rewards of your hard work.

6. Harvest & Flush (Week 9-10)

Products: BIG DIAMONDS (week 9), then clean water (week 10) Final Fine-tuning: Use BIG DIAMONDS in the penultimate week and finally rinse with clean water. This ensures the plant uses its remaining nutrients and delivers a cleaner, more flavorful harvest. When are you ready? When the leaves start to turn yellow and change color, you know the plant is getting ripe. Be patient: Your reward will be all the bigger and more aromatic. Last Tip: Most varieties require around 10 weeks in flower – even if the package says otherwise. Your patience will pay off in quality and yield.
