Blue Dream Autos (2), 4x2 Tent, 2 TS600

We're off to a good start! The seeds took about 3 days to sprout from the soil. These ladies are growing and changing every day, it is a delight to watch. I noticed the humidity was getting low so I added a small humidifier, but only to keep the humidity from 70-80% at 75deg F for early veg/post germination. I probably won't need this as the plants get older, as humidity generally hovers around 45-55%. I also added 2 clip fans for circulation and to build the stems up, plus I'm leaving my duct fan vent open just to get some circulation. I have not installed my ventilation fan as of yet, not really sure when to start using it or if I even need to at this point.
