Lighting and area

[peacock]

Hi All,
I have not posted for awhile, so I'd like to ask a couple of questions

I have two rooms. Both are 7' X 8'. One room has a 6' ceiling and the other is 8'.
At present I'm using a 400 MH in the Veg state.
I'm in the process of buying lighting.
The plants will be ready for flowering soon.
So, I was thinking of buying Three - 600 switchable(MH and HPS), for the flowering area or maybe 2 - 1000 will be better since Lumatek has just made a 120 V - 1000 switchable.
In the other area what should I use (Veg.). I have 400 watt MH(old style) .
Use the 400 MH with a 1000 watt or buy another 400 switchable.
How long is a rule of thumb, you use for Veg.?
If it only a week or two maybe the 400 Watt MH would be enough.
I have also heard that some use HPS for both veg and bloom.
Just starting, so have lots of start up question.
If you have a link on this forum to read that would be great.

Thanks everyone.

400watt MH should be enough for the veg room if you want just add a couple bigger Cfls.
As far as the Flower room I would either go 1 1000 watt HPS or 2 600 watt HPS. either way should be plenty of light for them just lower them about 12-18 inches away from your plants. Good luck And happy smoking.

Well, I find it hard to comment:
You told us that your rooms are 7 ft x 8 ft which is 56 ft2 and at a minimum 3K lumens/sq ft, you'd need around 160 K lumens. This is a lot more than your 400 MH will put out; therefore I can only guess that you're not using a lot of the space.
If that's true, first I ask you: how much spill are you getting from the lamp? If much is being wasted I'd plonk some lightweight reflector boards around the plants.
I use HPS for veg and bloom, but supplemented with some CFL. (300HPS+100CFL) It works fine.

1k hortilux = 145,000 L.. or "almost" enough to supply 1 room with "minimal" recommendation..
