Day 0 - placed the seed in between damp cotton pads, in a sealed zip bag
Day 1 - tip of the taproot came out, waited another day for it to grow up to 1 cm
Day 2 - mixed Top Crop's "Complete Mix" with perlite+vermiculite. Added about 2/3 of GHS BioGrow recommended amout, since the soil is already filled with nutriens. Considering that Royal Cheese Auto is quite short in veg, that should be quite enough. And, about 3 litres of 6.5ph tap water to moisturize the whole bag pot.
Finally, dripped about 2 ml of Advanced Nutrients Piranha around the hole where the seed went in.
