Popped 18 Jack 47 XL Auto into a SOG Setup all 18 will be In a 4 x 4 area. Everything outside of the first 3 x 3 space I assume is going to get a slightly smaller yield due to Growers Choice recommending the light for a 3 x 3 space for maximum yields. I have 18 Dark Devil Auto by Sweet Seeds right next to these girls. The room is a 16 x 16. Avoiding the tent this time to have an easier time cooling the room. I will be picking up Botanicare LT 4 x 4 trays to put under the girls so when watering time comes I do not flood the room.
