The seeds were germinated for 36h in a glass of water, in the dark, then transplanted to a jiffy pellet.
I kept it inside a humidity dome at 30°C and 100% RH, until the seedlings appeared, under indirect light.
Then, I planted the jiffy pellets in a fabric pot with organic super soil, under 150 PPFD of light.
The GC seedling was still stuck inside the seed when started to show the first serrated leaves, so I removed the seed and opened the cotyledons by hand.
They were kept at 27°C and 60% RH inside an adapted 80x40x160cm (WxDxH) wardrobe.
