Help? Max yield from small aero system?

Hey guys, today I need some help, I have a question! ... I'll give you a brief run down of what I'd like to run next grow, and can some experienced people please tell me what you think the max yield I could get would be and how to go about getting it, cheers! (I haven't run an aero like this before so really don't no what to expect).

Here's the set up.

- Aero system is a 75 Litre container with 4 plants in it, it's basically like this: http://www.simplyhydro.com/images/aeroponics.gif
That's all you really need to know about that unless you have other questions.

- Nutrients are:
Veg NPK = 35-15-55 (Growzilla)
Flower NPK = 30-30-70 (Budzilla)
Plus an organic bud enhancer, not sure what's in it, but guess it helps and seen as I already have it available, I'll use it.

- Room is 1.2m (3.9ft) x 1.2m (3.9ft) x 2m (6.5ft) [tall], all lined with white plastic etc.

- 2 15cm circulation fans.
- 200mm air intake
- 250mm air exhaust (centrifugal) can't remember how much air it pumps but the air exchange is huge.

- Dehumidifier (if required)

- Veg light is 400W MH and flowering is 600W HPS (I also have a 600 MH available).
- Veg photoperiod is 18/6. Light's have reflector etc.

- Length of veg period is open to suggestion.

- Flowering period will be 8 week strain of some sort of Skunk or AK, either way it's guna run 8 weeks about.

- Thinking of putting a screen over them to keep em even (ScrOG) but open to suggestions as to whether that is a good or bad idea.

Hope some of you can help me out with some idea's!
Fell free to ask questions, I'll update at later time with more info if people want it, maybe get some pics in there.

Cheers!

I'm bumping this since i'm tryin the same thing basically

me too! 400 watt aero

use the church strain you might be able to get a couple pounds in that space-best conditions possible obviously. Flower up to it reaches about 2.5 feet make sure you bought Bushmaster by Humboldt County's Own. Keep the light at 10-12 inches away during flowering balancing it directly in the middle. Are you planning on growing a 2nd batch while flowering ie vegging more plants while flowering? If not utilize that metal halide in the setup as it will increase your yield. What bulbs are you using? Consider looking at the spread of the spectrum in your light bulb if it is available.





I included this picture for some food for thought. I will not get into a discussion of Photosynthetic Photon Flux Density now, but I would advise you to do some research on it then look at bulbs which have higher PPFD ratings... one that I know of is an Osram Plantastar 600w hps bulb. Have fun researching.

Got the best bulbs available to me without getting a 1000W combined spectrum bulb, although it's so tempting to get one, can't be paying the power bill on that best at the moment.

I've been in and out of the spectrum argument for a long time, still haven't got conclusive results on it haha.
