Mephisto Quadruple Berry in living soil

Seed was soaked for 24 hours in water with a drop of Liquid Oxygen till it sank, a small root had broken from the capsule by this point. To avoid the soil being too hot for the developing seedling, a coco plug was first hydrated and then soaked in 1g/l of Ecothrive Biosys before the seed was planted in it, 1-2mm below the surface. The plug was then planted level in the soil. Pot is a 5gal Grassroots Living Soil fabric pot, with Pre-mixed Living Soil: AUTO by Living Soils Fertiliser with added lava rock and Black Pearl charcoal soil builder
