PC Box Grow Blue Mystic Autoflower Fem (Need advice please!)

I decided to create a new pc box for a new strain I ordered Blue Mystic Autoflower Feminized from Nirvana Seeds. I am needing some help along the way I don't know if I will continually update this thread, but I would like to if possible.
----------------------------------------------------------------------------------------------
The first question I want to start with is how far away from my light should I position the seedling? After starting on my first grow which is still in progress I am more aware of stretching. The idea I have in my head now is 1-3 inches away from light (limited space in box though) pretty much as close as you can get it without burning the seedling.

The box is anywhere from 80-100 degrees daily and maintains on average a temp of about 95-100 (I know its high)

What are the solutions to this I have an intake fan which is the lower fan outake is upper fan.

I have been swapping out a cup of ice starting today to try and lower the temp and opening the box whenver I can to lower the temp, but the higher I have the seedling the hotter the temp is.

I just removed 1 Great Value 60w replacement (14w actual) 6500k daylight fluroescent bulb to try and lower the temps

Lights:3 GE 100w replacement (26w actual) 6500k 1600 lumens daylight fluorescent bulbs for VEG
3 GE 100w replacement (26w actual) 2700k 1650 lumens soft white fluroescent bulbs for FLOWER
Water: Deer Park Spring Water (ph of around 6-7 can't remember right now)
Nutes: Miracle Gro All Purpose Plant Food
Medium - Hyponex Potting Soil by Scotts
6 days old (from seed) 4 days old (from sprout)
(Light Cycle of 18 on 6 off)

I'm aware this is a cheap ass grow, please don't insist on me doing a different grow because this is what I'm limited to at the moment. All the resources I have are all that I am capable of getting access to at this time. Please only recommend things that I could get from a walmart or small farm store. I'm from a small town and very limited on new resources I'm already aware on how they could help. Thanks lots guys

what is your ambient temp? you will never get it lower than that if you can even reach ambient

TL;DR
What I really need to know for the now is should I raise the plant higher to avoid stretching at the cost of a higher heat between 95-100 or is the height fine now?

Dimensions of box 18 inches tall, 18 inches long, 8 inches wide.

Ambient temp? Like a room temp? Plant is on its night right now and I checked temp its at about 78 degrees F in there. Is that what you are asking for?

Right now I have the central air in my house off and the window open and will probably for the next few days, my room is typically at around 80-85 degrees ambient temp =/ I think the heat from my PC and 2 PC box grows raises it dramatically even with Central air on..

well you figured out your heat problem now just work on lowering your ambient temp

If I can't get my ambient temp lower then what should I do. Keep my plant closer to light to prevent stretching even though its a hotter temp or lower it and replant after if it stretches too much. I'm replanting regardless so I feel like this is almost a stupid question lol. Sorry just inexperienced trying to learn as I go.

Not sure if bumping is allowed but bump
