Zero Dollar PC Grow Box Project

Simple...
I love weed, Im flat broke
I have very little experience growing but ive done it before so im no newbie

SO FAR....
Emptied out old PC as best I could and scrubbed it clean
Germinated 4 seeds 2 Chronic 2 Bagseed
Planted them in some mystery soil from a plant outback
and waited for them to sprout, today was that day

Their current containers are ridiculously tiny, but i do plan to try and keep them as small as possible although i might have to upgrade to containers maybe 3x the size they are now. My ideal size for the plants is one foot, or smaller.

I plan to use no more than 2 cfls for the whole process.

Im uncertain on nutes, i have two types, *Type 1* 12-10-5 in the form of little pebbles. *Type 2* 18-18-21 in the form of powder you mix in water, both for tomatoes

It can get hot inside a grow box, i have 3 fans and all the stuff to set them up but it would take alot of work, im wondering if frozen water bottles can help

Now, i understand that these conditions are less than great but i trust what i have will be adequate. This is ALL i have and will have to work with.
Thanks for reading, any questions, tips, or help is greatly appreciated.

DAY 2
Wow these guys grow fast, actually i hope they aren't guys lol, one seedling still has its shell over its head and i dont know why
any ideas on which tomato nutrients to use and when?
only going to veg. for a week then straight to flower

heres some visuals

give them 1 more week, 2 at the most and then switch them to a 12 hour light cycle.

if not they will get too big for your box...

DAY 4
Three seedlings left one didnt make it out of its shell.
Ive added a fan, heres some pics

Neat setup man! Do you plan on topping, scrog or lst?
I will be doing a bit of all 3 in my case.

Keep up the good work!

DAY 11
Unfortunately im down to one plant, i had 2 bagseeds and 1 chronic, the chronic just plain stopped growing maybe i did something wrong when i relocated it to another container, didnt want to throw it away so i stuck my finger in the soil in my backyard and put the little guy in there, if it shows signs of improvement I will take it back.
One bagseed shriveled up and died, the only one left looks promising but i will take extra care of it. Just in case its male i will start to germinate my remaining 3 bagseeds.

Nothing new in my setup, still as low budget as it gets, but i have been taking my plant outdoors for sunlight for about 5 hours a day, the remaining 13 hours under my 2 cfls.

+Rep for advice and help.
