Description
Concentrated stinging nettle - the oldest tonic in the book, standardised
Terra Aquatica Urtimax is a concentrated extract of stinging nettle, Urtica dioica. Nettle tea has been used by growers for generations; the point of a standardised extract is that the silica, iron and plant acids arrive at a known strength instead of whatever a bucket in the garden happened to produce.
Key Benefits
- Silica for stem strength - stiffer stems hold a heavy canopy without staking
- Naturally iron-rich - supports chlorophyll and green colour through hard growth
- Standardised strength - consistent, unlike home-brewed nettle tea
- Root or foliar - effective either way, and a foliar pass works quickly
- Organic input - fits an organic programme and a mineral one equally
Floppy stems that cannot hold the flowers they set
Growth pushed hard under strong light gets tall before it gets strong, and by mid-flower the branches are bending under weight they should be able to carry. Silica is laid down in the cell wall as the tissue forms, so it has to arrive during excessive stretch and early flower - adding it late does very little.
How to Use
- Vegetative growth: 30 ml per litre from the first true leaves onwards
- Preflowering: 30 ml per litre while stems are still extending - Terra Aquatica do not list Urtimax once flowering proper begins
- Foliar: 20 ml per litre as a fine mist, lights off
- Late flower: taper off - stem structure is already set
- Mixing: add to water before the base feed, and never alongside a strong acid pH corrector
