I would switch that arround so the bloom area is on the bottom. The heat from the HPS lamp will heat the floor of the veg room this will aid in seed germination in the veg section.
You have 7.5 sqft in each area. the four t-12 40w bulbs in the bloom section is 1200 lumens each The 70w hps is 7000 for a total of 11,800 lumen which is 1573 lumen per sqft. I like to have 2500 to 3000 lumens per sqft for flowering, go below 2000 and the grow gets longer and the plants streatch to reach the lights, buds could also get loose and and fluffy without enough light. I would replace those 40w tubes in that section with 6 42 watt cfls at 6500k they are 2,800 lumens each this would give you 3173 lumens per sqft in the bloom room.. Much better than the 1573 you have planned.
The veg section you dont have to be as conserned about the lumens I normally shoot for 2000 lumen per sqft for the veg room.

kiss-ass
Actually the t-12s I bought are 2180 lumens each (Reading off the Box) and are in the 6500 K spectrum

7.5 sqft X 3000 lumens = 22500 lumens this is what you should be shooting for.
The HID lamp is 7000 lumens, then add in the 4 t-12's(at 2180 each) you have and its a total of 15720 lumens. Adding 3 more of those t-12 bulbs will put you where you should be. So draw 3 more yellow boxes!! ROFL

BTW the 50w MH you have in veg area is somewhere between 2700 and 3400 lumens. You may be better off replacing that with 1 or 2 more of those CFL's you have listed there

lols if it were only THAT easy. Talk about sweat equity. I am not being an ass intentionally but since the pots that the plants will be in are 15" tall should you not remove 6 cubic feet at least since that area of the flowering room is being taken up- by soil> ????????? LOL
And whay are you talking square feet should it not be in 3 dimentional cubic feet

Cause 8 42 Watt CFLs and a 50 Watt MH are in my vege room already. I had great success with the CFLS alone but I got a low wat MH cause I heard it is good for penetration.
exactly though... if just the cfl's worked great for vegging, why get overkill? put the MH in the flowering room and your plants will LOVE to eat up both spectrums during flowering. just my .02
edit: and also, since the MH is better for penetration, it would be more beneficial when your plant is in flowering stage anyways, this is when it triples in size and gets way bushier

your not being an ass at all your just misinformed. The length and with of the area are multiplyed together to give you the SQft. Your not going to multiply that by the hight of the room giving the cubic foot because its the hight the lights are hung at an optimal hight from plant and are continued to be moved as the plant grows. Anything you read anywhere about the the correct amount of light to have will be giving you a factor in SQ ft not Cubic feet. You cant trip over a shadow there not 3 dimentional.

But wont the HPS at a higher wattage give me even better penetration

A 50-75 watt HID isn't going to give you any sort of substantial penetration. The penetration comes from the high intensity(like 50,000 lumens @ 400 watts).
A 55 watt CFL produces 3600 lumens. A 50 watt MH produces about 3400.
So, in that sense, you'd be much better off with a 55 watt Daylight CFL.

"Penetration" isnt really the way to look at it. Reguardless what type of lighting make sure that you have enough lumens per sq ft and you will be fine.
I totally agree with this. If they were 400W or better HID it would be a differant storry. But those tiny HID lamps only put out 3400 lumen or so and produce alot more heat for that small area. Hang whatever wattage cfl's in there to make up for that 3400 lumen and your better off in that small box.
Yeah a HPS will give you better yield but he has more flourscent than anything else I would highly doubt that 50w of hps is going to make any noticable differance at all.

I agree too. ButI have managed to grow in what others wouuld swear was impossible to sustain plant life.
I am not that conscerned with my vege room any more, that has more than enough Lumens per square foot. 8x 42 wat CFLs + 1 50 watt MH in a 1.5 foot high by 3 feet wide by 2.5 deep. Just enough to vege 12 sprouts .
lol
Flowering room is 3 feet high by 3 foot wide by 3 feet deep after walls and lighting and pots and misc
for that I have 4x 4 foot T-12s 6500K spectrum and a 75 watt HPS and have just aquired 2x 300 watt cfls 2700K for the flowering room.
Focus on the flowering room.
4x 40 watt 4' T-12s 6500K Spectrum each 2180 Lumens Each
2x 65 watt 2700K spectrum 3900 Lumens
1x 75 Watt HPS 7000 lumens?
4 foot H X 3 foot W X 2.5 foot deep Room

thats 23520 total lumen for 7.5 sq ft giving you 3136 lumen per sq ft which is just fine.

ok now any one have a mini keg or an old fosters huge can 2 please for the reflectors on the 65 watt cfls casue they are 10 inchs long by 5 wide lol
