I had a busy week. I updated my 4" exhaust fan to a Cloudline 6" booster exhaust fan and a bigger carbon filter. I also added another mini-fan that can oscillate and I had to add a heater. Why you ask? Because I got a CO2 tank from a friend and it is recommended to have temps in between 85-95 degrees. Granted I could have used it three weeks ago but better late than never. I have a nice CO2 monitor inside the chamber and I use the internal video camera to watch the readings. I have also added some HydroGuard to help the roots. They are slightly brown and another grower recommended it. Daphni continues to grow well and has maintained her dark green color. She has also started to make pistils and they are starting to form into buds just three days after first pistil sighting. I can smell her now too. latest readings are Air Temp = 79F, Humidity = 42%, PPM = 1810, pH = 5.9. Concerning my roots, I put a black trash bag over the top of the reservoir to keep as much light out as possible. The reservoir is tan and white and I think light was getting thru.
