how many plants could i veg under a 600w hps?

what the maxiumum i could ved under a 600w hps?

i want to veg around 20 under it then bang them under 4 600's in flower

I'd probably go with at least a 1000w for that many plants, but heck, try it. why not?

if there in one gallons you can do 36. I raise my light so i get a good spread and i run 36 under a 600 untill i transplant
