Good Morning A.F.N 4:08 am I should be in bed .
A little show and tell this am for those that are interested . The first picture is my DIY Par meter . Instruction via Youtube . The 2nd picture is my setup with 2 Panda cobs 400 watts set at the prescribed 24 " I am generating 500 par over 90% of a 4' x 4' area the outer areas are at 400 more or less . As I understand it 400 to 700 Par is what is usable for cannabis . I guess we'll see .
