how many lights

i wanna know if its possible to use 2 600w hps for 24 plants. 8 each in about 2'x 4' trays

depends on how you set it up but yes done right thats a nice set up

ya but id say there gonna have to be small sog plants.

ok so if add another light will it affect yield or should i stay with that setup do to budget and if you ask its top feed with recirculating res

stupidclown or cyyberesecks no more info?

i would stick with that but i'd go with three by three trays one light over each
