Purple Encircled

They're growin'. Roots hit the res on lefty. No roots visible yet for righty. Still on 1:1:1 CalMag, Armor Si and Rapid Growth in RO water. Took the clear solo cups off the seedlings in order to increase light load to 50%. I stuck in a humidifier with the humidostat set to 80%, and the lids around the seedlings get sprayed with water every two hours or so.
