Can I use thick cardboard boxes lined with tin foil for a grow box?
I can only find CFL's in 2700K will these work for the Veg stage and the Flowering stage?
Can 3 Plants be ok in a 2ft X 1ft 7in X 3ft 6in,
Then 4 plants in a 2ft 7in X 2ft X 2ft 4in?
With a 6in fan in the bottom corner and vent holes across the top so the heat rises out of the box?
