Kusarudzwa

Mamiriro ekushanda

1. Kupisa kwemamiriro ekunze: kumusoro muganho + 40 ℃, kuderera muganho -15 ℃;
2. Altitude: ≤2000M;
3. Humidity: Zuva nezuva avhareji kukosha hakusi kukuru kupfuura 95%, pamwedzi avhareji haina kukura kupfuura 90%; 4. Kudengenyeka kwenyika: isingasviki masere madhigirii;
5. Hapana moto, kuputika, kusvibiswa, kuronga kwemakemikari uye nzvimbo yakanyanya kuwanda.
