Help with advice on a 16x18 for Flowering

Idea is to have four sections each with 6 plants vegged in soil for 30 days under combo of 400w and 600w. Est tops height 24-36' tall trimmed under growth between the soil and the bottom of plant approx. 10-12' the idea or hope is to have them have a canopy no more than about 24-30' deep. These are rotated into and out of in 2 week cycles like in the "get a harvest every 2 weeks" thread.

I have decided that due to the budget, I'll use a light mover. I have also decided to use a cool tube and a 600w so I can hopefully get it to be 6-9' or even closer to the canopy, (I looked at the difference in lumens at the 6-9' range vs 1000w at 18 and the 600 was actually more, but it does inverse as the 600w goes farther from canopy) and/or to allow for the hight difference that will be experienced over the cycles, since there will be some growth the first two weeks or so. This will be on the mover to one side to cover two sections. I will also be using Co2 and have the ability to control temps with a/c and space heaters and using cool air to help with the temps from the light.

The plan was to get another 600w for the other side of the mover, to flower the other two sections. But I was thinking about light penetration and the fact that they will be growing for the first few weeks. The one side would have to be a lower temp emitting light due to the hight difference that will happen on that side as the new to flowering plants come in. But the other side would not have to have this taken into account and the light will/should be at a consistent hight above the canopy on this side.

So this got me thinking about using a 1000w on the other side and move the plants that have been under the 600w for 30 days over to this side, as they have stopped growing and are now producing.

Give me some advice on this please, I do plan on increasing the number of lights in the future, once I can afford it. But I figure it will be a few months down the road. I was also wondering if this could also help in the fruits' flavors or aromas through additional resin production to protect the plants from a brighter light or have other benefits like larger flowers?

I hope to avg 3-4 oz per plant... Realistic? If not, how do I get there? ...and if I want to increase this to 9 plants each with 4oz what do I work towards to making it happen, as far as lights? I prefer to keep the 'number' of plants smaller and if that means larger plants then that is ok (I don't want to push the boundaries of 99, too easy to get there with clones and moms)

My advice is that if you want bigger buds you need bigger lights. I recomend the newest bulbs out there. They are produced by Hortilux and they consist of a 600wHPS+400wMH in the same bulb! The light spectrum produced is one of the closest thing to sunlight man has created.

for a room that big, most people would consider nothing less than 1KW lights...

but i understand, you are on a budget... do you already have any of these lights? the light movers are pretty expensive... almost as much as another light, which i think would be more effective (but cost more monthly to operate)

as far as distance from the canopy - 9" is pretty close for any light, it looks good on paper but once you set it up you'll notice that the light wont spill very far and there will be dark sections... if you use cool tubes, or vented hoods with 1KW the plant will respond well because it will be bright on top, but also the 1Ks have so much better penetrating power that even the buds on the bottom of the plant cant hide from it...

i have an approx 42" wide room x 7ft long with a sloped ceiling and i use 2 1000w HPS bulbs... the 600 watt systems are usually exactly the same price as the 1KW systems, but sometimes more expensive...something to think about.
