Benefits for the grower
The organically bound nitrogen (2.6% of the 3.3% total) enables Alga Bloom to release nutrients gradually, preventing root burn and ensuring consistent feeding. The high potassium content of 5.4% K2O promotes sugar and essential oil biosynthesis, resulting in flavourful and aromatic end products. The complete Plagron Alga line is specifically developed for growers who prefer a natural approach without compromising on results.
Combinations & alternatives
Combine Alga Bloom with Plagron Green Sensation as a bloom booster for denser flowers and increased yield. For the vegetative phase, use Plagron Alga Grow as your base nutrient. Growers seeking a mineral-based bloom feed may consider Plagron Terra Bloom as an alternative.

What is the correct dosage for Plagron Alga Bloom per litre of water?
Apply a maximum of 4 ml Alga Bloom per litre of water, equating to a 1:250 dilution ratio. Use this solution at every irrigation throughout the full flowering period. Always shake the bottle well before use to ensure homogeneous nutrient distribution. You may start at a lower dose and gradually increase to full strength.
Is Plagron Alga Bloom suitable for hydroponic systems?
Alga Bloom is primarily formulated for use on soil and coco coir substrates but can also be applied in hydroponic setups. Be aware that organic nutrients may cause clogging in drip irrigation systems, so flush the system regularly. For dedicated hydroponic cultivation, Plagron Hydro A&B is a more suitable alternative.
What is the difference between Plagron Alga Bloom and Terra Bloom?
Alga Bloom is a 100% organic fertiliser based on seaweed extracts with organically bound nitrogen that releases gradually. Terra Bloom is a mineral-based nutrient that is more rapidly available to plants. Alga Bloom fits within a fully organic cultivation programme, whereas Terra Bloom provides more precise control over immediate nutrient uptake.
Can I combine Alga Bloom with Plagron Green Sensation?
Yes, Alga Bloom and Green Sensation complement each other excellently. Alga Bloom covers the base NPK requirements during flowering, while Green Sensation acts as a booster delivering additional phosphorus and potassium for denser flowers and higher yields. Always follow the Plagron feeding schedule for correct weekly dosages.
