Substrat din roca vulcanica de la Ikea

Salutare,

Da...da...stiu ca e un pic ciudat dar sunt curios daca e OK.
Deci, in weekend m-a dus nevasta-mea la Ikea si, din intamplare, am dat peste substratul de mai jos.

Un PDF cu descrierea produsului: http://www.ikea.com/ro/ro/manuals/vaxer-substrat__AA-1840756-1_pub.pdf

Unde scrie:

Growing media
Pumice stones: naturally expanded
volcanic material
Net weight: 1800 – 2160 g (3ltr)
Volume: 3 L

Recommended use
This growing media can be used to grow
plants and seeds. Its porous composition
retains water for longer than alternative
growing media. It is most commonly used
in hydroponic growing systems. Be sure to
fertilize with plant nutrition as it does not
contain nutrients needed for growing.
Cleaning
Pumice stones can be reused 3-6 times.
Clean the pumice stones after each usage
by placing in a bucket and adding boiling
water. This process removes organic material,
such as roots, from the pumice. The
organic material will float to the top and can
be removed once the water cools.
Safety
Do not swallow. Keep away from food, drink
and feed.
Storage
Store in a dry place. Close packaging after
use and keep out of reach of children and
pets.
Particle size: 0,5-3 mm
pH: 6,4
Electrical Conductivity: 10-20 mS/m
Salt content (KCl): total content KCl
(approx) >0,19 g KCl/litre
Humidity: 40-55%

E fain ca are o culoare care nu prea se gaseste.

Ce parere aveti?

Este spartura de lava la nevertebrate cu 8 lei/kg .

Eu nu m-as risca sa bag in acvariu chestia asta deoarece nu stiu exact ce contine .

Pai vrei sa plui plante emerse nu ? Dar cred ca nu ori ce planta suporta asta ...eventual poti sa il combini sa pui jumate pamant de flori si jumatate din asta cdaca spune ca retine apa mai mult cred ca ajuta..dar inca o data nu cred ca ori ce planta suporta lipsa relativa de nutrienti
Le: Acu mi-am dat seama ca o vrei in acvariu.

E piatra ponce maruntita (piatra vulcanica).
Daca nu e calcaroasa...si nu cred ca e, ar trebui sa fie buna.
