So you have a 12 sq ft, 11200/12=933 lumens per sq ft. Thats not enough. Add more lighting. 3000 lumens per sq. ft. is about as low as you want for veggin. Of course thats in my opinion and I dont do everything as it is posted on here. But, I grow massive plants, so I must be doin' summin' write Best of luck.
