Added some Grow Big to the feeding schedule this week. Transplanted a few days ago. Also added an inline duct fan for air intake. I have the tent in my basement so I decided to run an air purifier in my grow room. Also have a filter connected to my intake fan to help prevent contaminants. Might get another Exhale co2 bag for this grow since it seemed to help last time. The Cloudline T4 is functioning great. Going to add a humidifier today since humidity has been hovering around 47 the last few days.
