i only planted one plant from bag seed... its my lil experiment to get better quality... this plant is about 6.5 inches tall at the 3 week mark... is this good or bad?? it is very tall i think and does not have many leaves... i am just putting it under a 825 lumens light is this enough? i been reading but dont see many pics of three week old and the ones i do see look nothing like mine? please help
