Product name: Multi Kelp Max – Umya
Commonly known as: Seaweed Plant Growth Stimulant
Active Source: Ascophyllum nodosum (Cold-water brown seaweed extract)
Umya Multi Kelp Max is a seaweed-based plant biostimulant designed to support healthy root systems, improve plant resilience and assist with nutrient utilisation in indoor plants. Derived from cold-water Ascophyllum nodosum seaweed, this supplement contains naturally occurring plant compounds that encourage balanced and stable growth.
Unlike traditional fertilisers that supply nutrients directly, seaweed biostimulants work by supporting the plant’s internal growth processes. These natural compounds help stimulate root development, support cell expansion and assist plants in adapting to environmental stress such as repotting, transport shock, seasonal light changes and humidity fluctuations.
Indoor plants grown in containers rely entirely on their substrate for root support and nutrient availability. Over time, container environments can limit natural biological activity that plants would normally benefit from in outdoor soils. Seaweed extracts help bridge this gap by supporting root signalling and encouraging stronger, more responsive root systems.
Kelp is particularly useful during transition periods such as propagation, repotting and acclimatisation to new growing environments. By encouraging root activity and improving plant stability, it supports long-term plant health rather than forcing rapid or unnatural growth.
When used alongside a balanced fertiliser programme such as Novatec Soluble Fertiliser, Grobest Organic Fertiliser or TerraPlus Natura N, seaweed supplements can assist plants in utilising nutrients more efficiently and maintaining consistent growth.

What makes seaweed biostimulants different from fertilisers?
Fertilisers provide essential nutrients such as nitrogen, phosphorus and potassium that plants require for growth. Seaweed biostimulants, however, support how plants use those nutrients.
Seaweed extracts contain naturally occurring plant compounds that encourage root development, assist cellular growth processes and support plant resilience during environmental stress. They are best used as a supportive supplement alongside a regular fertiliser programme.
Why are seaweed supplements especially useful for indoor plants?
Indoor plants grow in controlled environments where airflow, microbial diversity and soil depth are naturally limited. In container-grown plants, root systems must work harder to absorb nutrients and maintain stability.
Seaweed supplements support root signalling and growth responses that help plants adjust to these confined growing conditions. They are particularly valuable during repotting, plant transport, propagation and seasonal environmental changes, where root activity and plant recovery play an important role in long-term plant health.
When should Multi Kelp Max be used?
Multi Kelp Max is most beneficial during periods of plant transition or recovery. This includes repotting, dividing plants, rooting cuttings, plant shipping recovery and adapting plants to new light or humidity conditions.
It can also be used periodically during active growth to support root strength and plant resilience.
How often should Multi Kelp Max be applied?
Apply during active growth or when plants are recovering from stress. It can be used alongside routine fertiliser schedules and applied either as a soil drench or foliar application depending on plant needs.
Reduce or pause applications during winter dormancy when plant growth naturally slows.
Can Multi Kelp Max be used with fertilisers?
Yes. Multi Kelp Max is designed to complement fertilisers rather than replace them. It supports nutrient efficiency and root health when used alongside other fertilisers such as:
• Novatec Soluble Fertiliser
• Grobest Organic Fertiliser
• TerraPlus Natura N
• Controlled Release Fertiliser
Is Kelp suitable for semi-hydro and pon growing?
Yes. Multi Kelp Max is well suited to inert growing substrates such as pon and semi-hydro systems where natural biological activity is reduced. It supports root metabolism and helps plants adjust to low-organic growing environments.
Which plants benefit most from Multi Kelp Max?
This supplement is especially beneficial for aroids, orchids, foliage plants, cuttings and imported plants recovering from transport stress. It is also useful for newly repotted specimens and plants establishing new root systems.
