The plant showed sign of sex this week. She continued to stretch but still managable. Tiny visible buds started to form. I defoliated lightly to open up light to the lower canopy area. I also started implementing CO2 in the tent this week with solenoid valve and a CO2 controller. I have set the PPM target to 1800 ppm. The light at canopy was around 1200-800 depending on the locations.
