I have 2 seedling currently growing under a 26w 6500k CFL light 24 hrs. They're both a week and 3 days old. They have airflow from fans and i know that heat isnt an issue. They are currently in regular potting soil but will be repotted today with much better soil. This is not a grow for the biggest plant or best bud, i just want a couple 6-12 inch plants. I have a couple large plant i grew from putting in the sun everyday and then flowered 12/12 hrs with 2700k cfls and it worked, but this is my first complete grow with lights so pleaaaase help! Ill post pictures!
