Description
Dutch Nutrient Gro A 和 B 是一种两部分基础营养素，用于在植物生长期实现最大生长，专为幼苗、插条和早期植物的强劲发育而设计。这种两部分植物营养素以清洁、高效的形式提供完整的植物营养。

Gro A-B 被描述为最高品质矿物质和营养素的理想混合物，旨在帮助植物在构建结构的同时达到最佳生长。它也被定位为一种方便的两部分配方，可最大限度地提高营养吸收，这在植物扎根、长茎和叶的生长期最为重要。如果您希望在整个生长期保持一致的基础，Gro A 和 B 可以作为可靠的生长阶段基础。

Dutch Nutrient Gro A 和 B 旨在减少结合和固化，从而更好地提高配方中矿物元素的可用性。它还被描述为减少矿物元素的浪费，使两部分形式的营养成分更具可用性。对于喜欢更简单程序感觉的种植者来说，“无添加剂或染料”的细节有助于将重点放在植物营养上，而不是额外的填充剂或着色剂。

事实层面很明确：Gro A 是 2-0-2，Gro B 是 0-1-3，这强化了它作为真正的两部分基础营养素而非单一用途补充剂的作用。除了 NPK 值之外，配方中还明确包含 Gro A 中的钙和 Gro B 中的镁，支持均衡的生长阶段营养，而不会使产品变得复杂。

Dutch Nutrient Gro A 和 B 非常适合那些需要高度浓缩的两部分基础营养素的种植者，这种营养素专为幼苗和插条设计，在最大生长和强大营养吸收的基础上支持植物生长期。

How To Use

How to Use 荷兰营养液 Gro A - 4 升

Step-by-step mixing and feeding instructions for 荷兰营养液 Gro A - 4 升.

Mixing & preparation

Fill your reservoir or watering container with clean, room-temperature water first. Shake the bottle of 荷兰营养液 Gro A - 4 升 well before every use. Using the feeding schedule below, measure the recommended dose and add it directly to the water while stirring. Allow the solution to mix fully before adding any other fertilizers, additives, or supplements.

Always add nutrients to water — not the other way around. Mix thoroughly between products to ensure an even, stable nutrient solution.

Week-by-week feeding schedule

Vegetative stage — Gro A

  • Week 1: mix 1.25 ml per litre of water or nutrient solution.
  • Week 2: mix 2.5 ml per litre of water or nutrient solution.
  • Week 3: mix 5.0 ml per litre of water or nutrient solution.

Flowering stage — Gro A

  • Week 1: mix 5.0 ml per litre of water or nutrient solution.
  • Week 2: mix 5.0 ml per litre of water or nutrient solution.
  • Week 3: do not use this product during this week of flowering.
  • Week 4: do not use this product during this week of flowering.
  • Week 5: do not use this product during this week of flowering.
  • Week 6: do not use this product during this week of flowering.
  • Week 7: do not use this product during this week of flowering.
  • Week 8: do not use this product during this week of flowering.

Tips for best results

  • Maintain pH and EC/ppm within the range recommended for your growing medium and crop.
  • Use fresh nutrient solution whenever possible and avoid leaving mixed solution stagnant for long periods.
  • Store nutrients in a cool, dark place away from direct sunlight and extreme temperatures.
  • Keep bottles tightly sealed when not in use to reduce air exposure and preserve product quality.
  • Use clean measuring tools and regularly rinse or clean your reservoir, lines, and irrigation equipment.

Common mistakes to avoid

  • Do not mix different nutrients or additives together in concentrated form before adding them to water.
  • Do not exceed the recommended dosage unless you are following a tested, crop-specific feeding plan.
  • Do not skip pH or EC/ppm checks when growing in hydroponic or soilless systems.
  • Do not allow the nutrient solution to freeze or overheat, as this can damage the formulation.
  • Do not ignore the directions on the product label for your specific crop, growth stage, and system type.

Warnings & Safety

Warning – Important Safety Information

Frequently Asked Questions
What does nitrate nitrogen (N) do for plants?

Nitrate Nitrogen provides a stable, easy-to-absorb form of nitrogen that supports steady growth, strong foliage, and reliable plant development without sudden nutrient swings.

Read the full guide

Why is soluble potash (K2O) important for plants?

Soluble potash (K2O) is important because it helps plants control water use, move sugars to new growth and fruit, and build stronger, higher-quality structure under stress. It’s unique from many other nutrients because it acts more like a regulator and transport helper than a direct “building material,” so the biggest benefits show up as steadier growth, stronger stems, and better finishing instead of just bigger leaves.

Read the full guide

Why is calcium important for plant growth?

Calcium is important because it builds and stabilizes plant cells as they form, acting as the structural support that keeps new growth strong and functional. Unlike other nutrients that drive color or speed of growth, calcium’s role is unique because it controls cell wall strength and membrane stability, making it essential for healthy roots, shoots, and long-term plant resilience rather than quick visual results.

Read the full guide

What is ammoniacal nitrate, and why does it affect plant growth differently than other nitrogen forms?

Ammoniacal nitrate describes nitrogen that behaves partly like ammonium and partly like nitrate, so it can drive fast greening while also shaping root-zone pH and nutrient flow. It’s important because the form, not just the amount, changes how plants build tissue and how easily imbalances like clawing, pH drift, and calcium-uptake issues can appear.

Read the full guide

Why do growers use calcium nitrate instead of other calcium sources?

Calcium nitrate is important because it supplies calcium in a fast, highly available form that supports strong new growth and healthy root tips, while also providing nitrate nitrogen for steady, usable growth energy. It’s unique because it delivers calcium together with nitrate nitrogen, making it especially effective during rapid growth phases when plants need both structure-building calcium and immediately available nitrogen at the same time.

Read the full guide

Is potassium nitrate better for quick deficiency correction than other potassium sources?

Potassium nitrate is often better for quick correction when the plant needs both potassium and fast nitrate nitrogen, because it dissolves cleanly and is taken up quickly, unlike potassium sources that don’t supply nitrogen. It’s unique because it can restore leaf color and growth momentum while also improving water regulation, but it can backfire if nitrogen is already high or if salt levels are already stressing the roots.

Read the full guide

Is nitric acid only for pH, or does it feed the plant too?

Nitric acid lowers pH, but it also adds nitrate nitrogen once diluted, so it can influence both nutrient availability and the plant’s growth balance. That makes it important for stable uptake, and unique compared to acids that adjust pH without contributing nitrate.
