light spacing
I have a question for light spacing layout, I understand that if you setup rows of plants and rows of light that you place the centers 40" apart, I like the "egg of life" pattern because light intensity would be spread out more evenly rather than have huge plants in the middle and small ones on the outside which is not very efficient according to doubleds experience, theory makes complete sense.
Although, what distance then do i place the plants??
I am planning on doing a 10-15 site MPB, I have it all figured just the spacing, oh and ill be doing g13, hashplant, purple kush, bubba gum, black domina, % Himilaya gold
What size room will I need for a 10 site MPB? (15'X20')
and for the 15 light room what size, and not rows of plants but spacing them offset, or egg of life style
thanks for the help
