Dilmma. Suggestions wanted!!!

My Dilemma. Need advice from the experts
I am wondering what would be the most ideal grow area size for a 1000w digital HID to give maximum yield?

Also what would be the perfect number of plants to put under the light again aiming for maximum yield?

I have some Raspberry cough, blackjack and super skunk. Germinated and just put in soil. I will grow in soil and will LST some and top others to try to keep a uniform height with the plants.

I am using a room for the growing area. Using a corner with the back of a wardrobe giving the third wall. I have a huge roll of Mylar cloth to make 4th wall and top (is this really needed?). The A/C is directly above the area which will bring in enough fresh air from outside and will blow directly on the HID.


Please give me any suggestions.

well obviously the smaller the space the closer the plants are to the light.but i would say for that light maybe a space of 1.5x1.5 metres

And plant numbers?
