Plagron Alga Bloom – Organic Algae-Based Flowering Feed

Type: Organic
Organic feeds come from natural sources. They work with the life in your soil, are gentle on plants and are hard to overdo.

Organic Flowering, With Flavour to Match

Ask organic growers why they bother and most will say the same thing: taste. Plants fed through living soil tend to produce fruit and flowers with a depth of flavour and aroma that's hard to get any other way.

Plagron Alga Bloom is the organic flowering partner to Alga Grow: an algae-based base feed for the flowering stage, certified for organic use. Its seaweed extract carries natural plant hormones such as cytokinins that support flower development, while extra potassium fuels abundant blooms and heavier, tastier harvests.

Why It Works

• Built for flowering: extra potassium for flowers, fruit and fragrance.
• Natural plant hormones: seaweed extract supports flower volume, aroma and taste.
• Organic and certified: suitable for organic cultivation.
• Feeds the soil: works with soil life for steady, natural nutrition.

For Houseplant & Garden Growers

Perfect for tomatoes, chillies, strawberries, flowering balcony pots and fruiting houseplants grown organically. Switch from Alga Grow to Alga Bloom as soon as the first flowers appear.
