These girls are almost finished and I learned a lot from this grow. I changed my lighting to 24/0 to better simulate northern hemisphere climate where ruderalis lives. I raised my lights to 30" above the canopy. I raised the daytime temperature to 86 for appropriate leaf surface temperature (L.S.T.). I finally bought a humidifier to maintain a 50% RH. After all that I have seen amazing growth on the left side of my tent and very nice flowers on the plants you see here!
