Plagron Alga Top Grow Box – complete organic nutrient kit for 1 m²
Building a balanced organic feeding programme from scratch requires selecting compatible products across multiple growth phases. The Plagron Alga Top Grow Box eliminates that complexity by bundling five purpose-matched products from the Plagron 100% Natural range into a single kit. Every phase from root establishment through late flowering is covered, with all components certified for organic cultivation by Control Union.
Kit contents and NPK specifications
The Top Grow Box includes the following products, calibrated for one square metre of growing area:
- Alga Grow 100 ml (NPK 4-2-4): organic vegetative nutrient derived from seaweed extracts and beet vinasse. Promotes balanced stem development and root architecture through proteins and amino acids.
- Alga Bloom 1 litre (NPK 3-2-5): flowering nutrient rich in phosphorus and potassium. The organic algae compounds improve stress resistance while enhancing end-product flavour and aroma profiles.
- Power Roots 100 ml (NPK 0-0-2): root stimulator that accelerates root mass development during the early vegetative stage for improved nutrient uptake throughout the cycle.
- Vita Race 100 ml (NPK 0-5-8): iron-based foliar feed that boosts chlorophyll production, accelerating both growth rate and the onset of flowering.
- Green Sensation 100 ml (NPK 0-8-9): 4-in-1 booster featuring a modified carbon molecule that enhances photosynthesis. Improves flower density, stress resistance, soil biology and overall yield.
Optimised feeding protocol
The included grow schedule maps each product to specific weeks in the cultivation cycle. During the vegetative phase, Power Roots runs concurrently with Alga Grow to maximise root establishment. Vita Race is applied as a foliar spray for enhanced photosynthetic efficiency. Once flowering begins, Alga Bloom takes over as the primary nutrient, supplemented by Green Sensation during the final four to six weeks. This sequential approach ensures targeted nutrient delivery without the complexity of multi-component mixing calculations.
Substrate compatibility and pH management
The Alga nutrient line performs optimally on Plagron's organic substrates: Batmix, Allmix, Royalmix and Promix. The microbial populations in these substrates convert organic nutrients into plant-available forms and naturally regulate pH levels. This biological buffering eliminates the need for pH and EC monitoring – a significant advantage for growers who want reliable results without constant parameter adjustment.
Top Grow Box versus Easy Pack
The Easy Pack Natural offers a streamlined alternative with three core products for up to four plants. The Top Grow Box provides the most comprehensive coverage with five components including root stimulation and foliar feeding, designed for maximum output from a 1 m² growing area. For growers seeking complete organic cycle management from a single purchase, the Top Grow Box delivers the fullest product range.

What is included in the Plagron Alga Top Grow Box?
The kit contains five organic products: Alga Grow (100 ml, NPK 4-2-4), Alga Bloom (1 litre, NPK 3-2-5), Power Roots (100 ml, NPK 0-0-2), Vita Race (100 ml, NPK 0-5-8) and Green Sensation (100 ml, NPK 0-8-9). A graduated measuring cup and weekly dosage schedule are also included. The quantities are sufficient for one square metre of growing area.
Do I need to monitor pH and EC with the Alga Top Grow Box?
When used with Plagron 100% Natural substrates (Batmix, Allmix, Royalmix or Promix), pH and EC adjustment is not required. The soil microbiome in these substrates naturally regulates acidity levels and converts organic matter into plant-available nutrients. Since organic compounds do not conduct electricity, EC measurement is not applicable for the Alga nutrient line.
What is the difference between the Alga Top Grow Box and the Terra Top Grow Box?
The Alga Top Grow Box contains 100% organic nutrients derived from seaweed extracts, certified for organic cultivation by Control Union. The Terra Top Grow Box uses mineral-based nutrients with direct plant availability. The Terra variant includes Pure Zym (enzymes) instead of Vita Race, as mineral substrates lack the natural microbial activity that produces enzymes in organic growing media.
Which Plagron substrates work best with the Alga Top Grow Box?
Plagron recommends Batmix, Allmix, Royalmix and Promix as the optimal substrates for the 100% Natural nutrient line. These CU-certified organic substrates contain active microbial populations that process the organic nutrients and regulate pH automatically. The Alga nutrients also perform well in open soil for outdoor cultivation.
