Lightly watered with ph 6.8 Smooth growing so far. Now that the first true leaves are showing I supplement with co2. I'm using an exhale 365 co2 generator. My ventilation creates negative pressure towards the ceiling of the tent so I just leave the co2 bag on the ground covered in an old tshirt to block some uv light.
@DonaldTrump, the sundae banana cookies is 4 inches. I had to cover the base in more soil to support it. For some reason that one stretched. Plants are weird. Congrats on the 2 foot monster!
