Pictures: How many mature ladies could I fit in this area?

My tubs finally dried up and are ready to be cut, i was going to put 3.75 inch net pots with root protectors. tho since i do have limited amount of space.. (the depth of my room is only 18"), i was going to grow 4 plants to full in this area, not sure if i want to have the plants staggerd or in 1 row straight down the middle with only 3 plants, what do you guys think i need some advice.
in the pictures, the circles with the crosses in the middle of em is where i was going to cut the holes for the pots,(theyre measured to 5 inches in diameter in the pictures), i put a light bulb in for reference size aswell as a standard 25' tapemeasure.

i hope you dont plan on using that incandescent bulb i see

i would go with 4 cause if u give em the right light they will stay short and be very bushy and put em in rows of 2 it wil be ezier 2 manage the light unless you plan on getting a pretty good light set up how many lights you plan on using and what kind

you also want air flow inbetween them so dont bunch em together 2 bad

hmm well first i would paint everything white then wait a couple days to let it dry and the fums from the paint to go away then start setting your grow area up ...... but on how many is depending on witch method you are going to use to grow....i would say go with Sea of Green and i dont know both messurments wide and deep looks tall enough ...... i have a 2x2x5 i believe i can fit 6 plants in there and its still going to be tight.... less plants you have the more nuts and air get to the ones that are there so i could fit more in there but the colas on each plant would be smaller but it might be wrong.........GROW FAQ at the top of the page is helping me. and there is DIY on the thread page theres tons of good threads in there..... well good luck

yeah i plan on painting it flat white, probably throw some mylar aswell, im gonna use a 400watt HPS, then about 4 or 6 2ft fluoros on the sides to get them nice and bushy, so you'd stick with 4 plants? BTY im using a drip system... thanks guys

you gonna be able to vent that 400hps?

ciggarettes should be baned !!!! keep growing .... i just put one of mine in a waterfarm pics tonight check out the link! yea no prob with the vent just get a temp humidty digtal gage to check i have a 2x2x5 depending on the weather out side its perfect.... make sure you have a fan on the light...4 plants sound just right.... look into lollipop coals trust me in the harvest it will be worth it !!!!!!

yeah i got venting planned out, its gonna work cherry, 180cfm with fan speed variator, and im lookin to buy a cool tube, so its pretty much covered .. any ways i was wondering if i could get by with 3" netpots, i was going to do 4" but i the guy says he wont have any in till spring...
BTW... Your set up looks hella clean, what pump you using, jus curious?

any one help me out on this one?i need to order soon thanks guys
