Seachem Flourish Advance Aquatic Plant Growth Supplement, 2 L, Root and Shoot Support

Seachem Flourish Advance is an aquatic plant growth supplement designed to stimulate root and shoot development, supplied in a 2 L (67.6 fl. oz.) size for regular aquarium use.

• Phytohormones, minerals and nutrients — support growth in aquatic plant roots and shoots.
• A 10–14 day initial period — focuses on stimulating root growth beneath the surface.
• Growth progression — enhanced leaf and stem growth follows the initial root-growth period.
• Regular use — enhances mineral absorption and improves plant disease resistance.
• Daily or as-needed dosing — use 1 capful (10 mL) for every 160 L (40 US gallons).
• Non-toxic formula — safe for all plant varieties, fish and other aquatic organisms.

Supporting healthy-looking aquatic plant growth involves more than what is visible above the substrate. Flourish Advance is made for aquarium keepers who want to support plants from the roots upward as part of a regular plant-care routine. Its formula combines plant growth compounds with minerals and nutrients, with root development as the focus during the first stage of use.

How does Flourish Advance support aquatic plant growth?

Seachem Flourish Advance uses phytohormones alongside minerals and nutrients to stimulate growth in both roots and shoots. Plant hormones have roles across several development processes, including cell division, shoot meristem formation and activity, photosynthesis gene expression, leaf senescence, nutrient mobilization, seed germination, root growth and stress response. With regular use, the supplement also enhances mineral absorption and improves plant disease resistance.

• Supports development below and above the substrate.
• Phytohormones are involved in multiple stages of plant growth and development.

What growth pattern can aquarium keepers expect?

The first 10–14 days after application are an initial induction period focused on root growth beneath the surface. After that period, significantly enhanced growth in plant leaves and stems occurs. This staged sequence makes the supplement suitable for routines focused on establishing root development before visible growth above the substrate.

• Root stimulation comes first.
• Leaf and stem growth follows the initial period.

How much should I use, and is it safe for aquarium life?

Shake the supplement well before use, then add 1 capful (10 mL) for every 160 L (40 US gallons) of aquarium water. Dose daily or as required to maintain plant growth. The formula is non-toxic and safe for all plant varieties, fish and aquatic organisms.

• Shake well before dosing.
• Use daily or as needed for plant growth maintenance.

Flourish Advance is suited to aquarium keepers caring for aquatic plants and looking to support root development, followed by leaf and stem growth, within an ongoing maintenance routine. Its plant-focused formula and stated safety for fish and aquatic organisms make it a fit for planted aquariums with aquatic life.
