12 days after the switch Tropicanna Banana shows her sex and officially begins flowering. On day 28 I started with the Bio Heaven and Acti Vera stimulators, although the soil is prefertilized for only 2 weeks, the girls are in perfect shape and for now they don't need fertilizers. I inserted wooden supports in the grow to reduce the effect of negative pressure, it took away important space for growing. This week i've stopped using the humidifier.
