Mephisto Quadruple Berry in living soil

D15-21 - A CO2 bag was added to the tent for the third week and DLI was increased to 25. The plant has grown quickly this week, coming out of its seedling stage and grown to about 9 cm in height, increasing its DLI as it gets closer to the light. It was watered on D18 with about 750ml of water mixed with Ecothrive Biosys mixed at a rate of 1ml per litre. This was way too much water, due to inexperience with living soils, and the reading on the soil moisture probe dropped to around 50mbar. The plant didn’t seem to be adversely affected (perhaps stunted slightly) and by D21 has increased to 70, suggesting there is now a more complex root system that is taking up the water. Next week should hopefully see more impressive growth as well as receiving its second water since germination.
