Stop bath will stop development immediately.
Stop bath will lengthen the fixer [hypo] life. Water will shorting it
Stop bath with indicator is not only inexpensive, it tells you when the stop bath is going bad.
1. Develop for 12.5 minutes.
2. Water "stop bath"
3. Fix for 8 minutes.
4. Wash thoroughly.
5. Hang to dry.
BUT the film was slightly fogged because I was loading it on the reel in the closet, pitch dark, when my roommate came in and turned on the light outside.
So there was a little bit of light coming in through the cracks, and the film being 400 ISO it probably fogged it
1. Agitation?
2. Time?
3. Why? Agitation?
4. Define "thoroughly"
5. How?
Take one film, split it in two parts, process them both the same way except the stop bath (use acid with one part, the other with water). Tell the difference.
Now, do the same thing but several times storing the fixer in two different bottles. Tell the difference.
Water is more regular.
The comprehensive indicator tells you - with the appropriate experience - that there're more than one way of doing things. Equally valid and applicable.

Do your own "changing bag"! When I was ten I made it with dark clothes (without ruining them) and was one of the first things I bought (not only useful for loading film)
A little bit of light is a little bit of light for any film
Congratulations for your first time!

Kodak et al have published articles about the advantages of using stop bath to stopping the development. It is great that you know more than all the film manufacturers that ever existed.
1. Develop for 12.5 minutes, agitating every minute by inversion
2. Water "stop bath" for not very long... maybe 30 seconds? I basically treated it as a wash step, agitating by rotation the whole time.
3. Fix for 8 minutes, agitating every minute by inversion.
4. Wash... The sink I was using had an INSANE "muzzle velocity", so to speak... basically I used it as a pressure washerI washed for about a minute.
5. Hang to dry on a hook on the wall using a binder clip.
6. Cut negatives after they dry and scan using a jerry-rigged consumer scanner method which works way better than I thought it would!
I do want to hear it! I've never done this before and I want to refine my process.A lot to say about this, although I'm not sure you're going to like it or be interested.
as much as I wish I could have a real stop bath it's just not happening
But keep in mind that I can't go much more complicated than this... and as much as I wish I could have a real stop bath it's just not happening

... using water in lieu of stop bath does change the contrastiness of the resulting negatives!
Excuse me wiltw,
can you share with us the source of that information, please?
Thank you very much in advance!
Sounds the main steps are known.
... everyone has his own chemicals or methods to follow, and sound all are happy with their methods and it is working, i will go/follow my method or say my steps regardless how others doing with theirs, at the end i feel it doesn't fail much or hard to fail when including the main/must steps.

Hmm, have not needed to explain this in a verrrryyyy long time, so I hope I am not misleading folks with rusty (and defective) understanding!
With stop bath, in both areas the developer action is stopped virtually immediately...consider this a 'baseline density' comparison example, when all goes according to Hoyle (Rules of playing cards)
The result of the above, compared to using stop bath
- WithOUT stop bath, water more slowly (than using stop bath) dilutes the developer rather than stopping it immediately
- developer in contact with the high density area of the neg is depleted more rapidly by development of much more silver in the darker areas of the neg,
- ...while developer more slowly depletes in the low density areas of development so it continues to work and build silver there.
IOW, the density curve is somewhat flattened, less contrast is in the neg and this results in you needing to print with a contrastier grade of paper to result in the correct full range of contrast. But equally bad, is the fact that since the entire tonal curve is compressed (flattened), the differential between two closely similar (but different) tonal areas is reduced as well, so the number of tonal steps in the print seem to be reduced, although the contrast range (white to black) is preserved via the higher contrast print paper.
- Rapidly slowed development (because of depletion) in the darker areas of the neg translates to less silver buildup in neg, so less dense (than using stopbath) which results in and in 'less white' areas of the print
- Prolonged development in the lighter areas of the neg translates to more silver buildup in the neg which results in 'less dark' areas of the print)
IN SHORT, especially for the poor bewildered OP, reduce the above mini dissertation to:
"When you do not use stop bath, it subtly drops the contrast of the resulting neg!"
Should I mix a 1 gallon solution like it says, and then dilute it half water/half solution in the actual tank?
You do not 'have to' use stop bath. But keep in mind that using water in lieu of stop bath does change the contrastiness of the resulting negatives! Depending upon the individual shot, you might or might NOT want to alter the contrastiness of the negative...but that is very advanced subtleties in technique reflected within the Zone System methodology (don't even think about it now!)
I have to apologize to everyone that too long of an absence from the B&W darkroom took its toll on my memory! The contrast reducing effects I had described were NOT associated with the use vs. non-use of stop bath. Rather, the contrast reduction of the negative is associated with the use of a WATER BATH in which the film is immersed in water while the developer continues to work in the thin areas but depletes in the dense areas.
