Soaking the seed until pops in Canna Rhizotonic.
Then plant in Canna Coco Pro Plus with Perlite 70/30 mix pre-soaked with a weak Canna Coco a&b feed and Rhizotonic @4ml/L.
Then left under the lights keeping an eye on humidity and temperature. Adding domes if humidity needs raising.
Fertigating once I've seen the first true leaves with Canna Coco a&b @ 2ml/l and Rhizotonic @ 4ml/l.
