4x8 tent - 3x 600W HPS - Opinions on running 3? Multi strain

[HigherTheHigh]

hello all!

only running a 4x8 tent for now and im vegging for one more week then ill be flipping into flower.

running 6 royal cheese in wilma systems, 3 lemon shining silver haze & 4 northern light clones.

northern light clones 10 weeks veg.
royal cheese 4 weeks veg.
lemon shining silver haze 5 weeks veg (topped 3-4 times).

im running 2x 600w hps at the moment and thinking of adding another 600w hps in week 3 flower, planning on running 3 in cool tubes so heat in the tent will be a minimum and kept to a steady 24-30c.

question is: will i get a bigger yield difference or not?

if i was to get a bigger difference what would it be (roughly) i get around 20oz per 4x4 with 1 600w hps.

i will upload some pictures soon of them.
thanks!
