Auto grow Variety Pack for Newbie

I finally have three seeds cooking. The ILGM Auto Girl Scout Cookie started to germinate but quit in the soil. I have two early seedlings of Gorilla Glue and Bruce Banner. I put a germinated Gorilla Glue in today. In my 2x4 tent, I have three plants in late flower with the light 16 inches over the canopy. The three seedlings are getting only tangential light so as not to overpower them for my perpetual grow. Overall, very disappointed with this ILGM 15 auto flower seed purchase. Four duds out of seven seed germinating attempts. ILGM told me to try to germinate all 15 seeds over time and they’ll make it good. We’ll see.
