Seedlings + one 3' Cubed grow box = failure?

[4mySoul]

K, so I have bought several strains of huanamari and am about to germ them but am not sure about a couple things, and seeing as this is my first op. I feel in the dark about several situations. First off, after the seeds have sprouted I have a 2x3.5x2.5 ft tall wooden box for which I plan on growing them in. I have already equipped the box with one fluorescent grow light(2ft with aluminum reflectors) hanging from the top but am concerned about ventilation expectations. The temperature of the environment I have deemed suitable, approximately 20* Celsius, but will poor ventilation poop on my plants? Of course I would open the box twice a day, once in the morning once in the evening, thus providing a refresh of air and a check on their water situation. The grow box does have a couple holes in it but no fan to power any movement, i figured the air would merely stay stagnant. Any takes on this dilemma? (I am planning on planting out twice because it is my first time, this means I would start off 15 plants the first time - in the grow box for about a month then plant out - right after the first transplant I will have the other 15 seeds finish germ'ing and into the grow box they go. Hopefully if I screw up the first time with either the transplant or sprouting I will have a second try. Obviously take 2 will produce some small low yielding plants. Well actually I'm running a bit behind on schedule so they will be moderately sized plants if all works out with take 1, no?) So my plan is to germinate the seeds and plant them in clear beer cups (the kind you get at shitty sporting events or the local fair) for their time in the grow box, giving them 17 hours of uninterrupted light. I will fill the cups 3/4 full of potting soil and my plan is to grow them to around 5-8 inches before transplanting to their outside environment. The outdoor spot is excellent in terms of safety but I don't think I will have time to dig the amount of holes I need. I have heard it's wise to dig 2 foot wide and 2 foot deep holes, if not 2 then 3 foot holes, and fill these with rich soil. I'm not certain about the type of soil to use but when I hit up the garden center I'm sure they will tell me a good type of soil for growing flowers in. So like I said digging 30 holes isn't really my thing. I figure 1 foot holes wouldn't be too bad. The lighting for the location is great, right in the open with a handy water source. It is near pine trees but ph doesn't really concern me... shouldn't be too hard to fix right? Temperature and environment shock is a concern of mine. People have talked about conditioning their seedlings for the transplant by taking them outdoors a couple days before. Unfortunately that's not possible for me, but i thought to myself why not take 2l pop bottles and right after the transplant put the bottles over top of each. The bottles would have the labels removed and several holes for the plant to breathing. When I return the following week these bottles would be removed and hopefully the plants will have survived. Of course I will protect the site with a fence or string, I've heard pissing around your site deters creatures, why not buy some deer meat and have a huge meal the night before when you get to your site just take a big shit? lol What do you guys think about the bottle idea, would it relieve the plant of some shock? I would return to the site I'd say once every week for watering. I would add fertilizer/nutrients to the water and avoid adding fertilizer to the ground only because if I screw up with the amount of fertilizer in the ground I fear it will ruin my crop. Anyway , comments/thoughts would be useful . thanks
