7 WhiteWidow Soil Growbox CFLs

So, this is my second grow, and i've decided to build a growbox.
At the moment, I have 7 white widow sprouts, 10 days after germination. They were started in blue dixie cups and were transferred just today into larger 8" pots.
GERMINATION:
To germinate, all 7 seeds were placed in a moist paper towel and placed inside a plastic bag in one of the top cupboards in my kitchen where there is no light. All seeds had sprouted 1/2" w/in 2 days and were promptly placed in soil (plain miracle grow organic choice) in dixie cups.
SOIL:
My soil is Miracle Grow's Organic Choice soil
I mixed 3 parts soil w/ 1 part organic worm castings
Mixed into the soil is perlite / vermiculite (ran out of perlite and couldn't find any more)
At the bottom of the pots, I have about an inch of sphagnum moss + vermiculite.
The soil has a pH somewhere between 6 and 7 (can't tell on color chart exactly where)
WATER:
My tap water runs out at about pH 8, so I use rice vinegar to adjust my water to pH 6.
Today, each plant was given 1 quart of water.
LIGHTS:
They are currently growing under 7 26watt daylight cfls (6500K) and 4 23watt full spectrum cfls (3000k).
I have a good number of 26watt (2700K) cfls and I plant on acquiring a few more 40watt (2700k) cfls for flowering.
GROWBOX:
My box is a rubbermaid 50 gallon (40" X 20.5" X 20.7")
I have lined the inside and bottom of the lid w/ mylar to increase reflectivity.
The growbox sits out of the way in my closet, but might be moved to a different location (CLOSET HEATS UP @ night)
VENTILATION:
For ventilation, I have 1 cpu fan (don't know CFM) that is hooked up to exhaust from the top of the box.
There are 2 intakes at the bottom end of both sides (lengthwise).
I also managed to fit in a small fan that helps circulate air inside the box.
I live in a fairly hot location (been > 100 F outside during the day), but my apartment is kept cool (approx 70).
Temperatures in the growbox reach about 85 F when the apartment is cool.
GROWPLAN:
As of now, I plan on vegging for about 20 days, and then flowering till they are ready.
I must be finished by the end of the semester (mid december) because I am leaving.

Comments / Criticisms / High Remarks Welcome!
Hoping to get a solid crop this time (my last grow w/ 2 females got me 0.34 oz.)
I'll keep this sucker updated as best I can.

Today is day 12 of veg
Plants look great

Temps are getting high. On the thermometer it reads 93 F. I am looking into different methods of cooling my box down.
I am going to get another exhaust fan (found out my current fan is like 80 CFM) to help w/ airflow. And I've put some big jugs of water in the freezer to keep my temps down at night when i have to close the closet. But these are only temp fixes.
I'm going to head over to wal-mart and see what I can do with what they've got.
Any suggestions appreciated!

Also, as you can see on the last plant, some of the leaves have yellowed a bit. This only has happened to the oldest growth and i believe is due to improper pH (had been watering with ph 8 tap water). But new growth looks great.

Today is day 17 of veg.

TEMPS HAVE BEEN GETTING HOT -> 90+ F
I believe this has stunted their growth a bit, but I moved my box out of my closet and have been keeping a close eye on temps. Last night, my box was outside and temps cooled down. You can tell new growth on the plants because it is bright green. It's good to see this morning, because they haven't grown much (TOO HOT) recently.

The soil is drying out. Going to water soon.

yep.
i've got 8 42 watt 3000k cfls and a bunch of 23 watt 2700k cfls.
I also got 2 13 watt UVB bulbs that i'm gonna test on 1 or 2 plants to see if the uvb increases trichomes.

DAY 7 of FLOWER
Been 1 week of flowering.

Watered today
pH ~ 5.5
1/2 dose liquid nutes 10-15-10
1 quart each
then 1/2 quart each 1 hour later.

Added/re-configured light setup in the box. Check it out.
Plants are looking strong. A few leaves got a bit burnt from fallen lights while I was away. Nothing too serious though.

I put ice underneath the oscillating fan -> keeps temps around 84F.
It can get pretty hot in the box when the soil starts to dry out, and my ice machine doesn't make ice fast enough for me to use more than 1 bowl / day. So I've been freezing some big jugs of water overnight and putting them near the intakes during the day.

yes thats a good question why ph at 5.5?i just orderd all my ph stuff.after finding out i had ph problems i was so mad(but it my first time so whatever).
i belive cfl's can produce some amazing looking buds to.how tall can your ladies get?

hey i just started my first grow just with some mid, didnt wanna pay without a little exp points under my belt, popped two seeds planted them two days ago, hadnt seen much since, a dab of water here and there, started with MG organic... got two 1000w cfl's (is that too much?!) directly over 5in potting plants(easily adjustable)... cooling fan...im going to follow and try to post some pics, if all goes well the first month, something special well be ordered!!
Ill definitely be following along and try to increase my horticultural aptitude in the process!!! Good Luck, cuz im trailing...

Well, ideal pH is like 6-6.5. And since my soil has a higher pH (7-8 ), I have to balance that by making the water a much lower pH (5.5). As the water sits in the soil, the soil will neutralize some of the acidity and cause the pH of the water to rise over time. So by giving them lower pH water, they are exposed to a suitable range of pH over time (say 5.5 - 6.5). which allows for maximum nutrient availability.

Sorry about your pH probs -> my first grow suffered horribly from pH problems as well -> I had PURPLE PLANTS haha -> these plants are from the same batch of seeds and they're nice n green :D. But never give up! It can only get better. Hopefully these CFLS will produce some amazing buds :D. I am going to get some more 40 watt CFLs (3000K) tomorrow.

Good luck on your grow! Hope you can learn a bunch from this thread -> I'll try and keep my posts as informative as possible.

I am giving them nutes now (at low strength) because when flowering, plants need potassium (K) and phosphate (P). My soil has nitrogen (from worm castings) so I was not worried about feeding them during veg (plus i didn't veg for very long and nutes can burn small plants). But now that I'm flowering and the plants are getting bigger, they will need phosphate (P) and potassium (K), and my soil does not have either of these. For my first grow, my plants stalled a bit into flowering (because they did not have these nutrients) until I gave em some miracle grow bloom nutes. So now I'm makin sure to cover the necessities.

Thank you all for your comments! I felt like I was writing to myself =p

No, I've got a soil pH tester kit where you add a certain amount of soil to your sample and it gives the pH of water + soil.

I have 5/7 males.... =[. what a bust. And they were the better looking plants too :(
2 potential females.

Ah. Well, at least I don't have to buy more lights =p.
