growing space

hi chaps could someone tell me how much space does each plant need to grow to a decant size, how far apart should they be. my room is 3ft by 4.6ft what is the maximum amount of plants i should put in there, also what size light, i have 1 x 600 watt hps.
thanks

It just depends on how big you want them to be. Usually 1 per every square ft will give u good size plants. I cant see the room, or how tall it is, but from that id grow about 4-6 monsters in there.

i have 22 in a 4x4

I have 2 in a 2x3
