Hello @Erich.
Welcome to AFN!
I have a little bit of experience growing in a cabinet. There is a link to my first grow in my signature line. I grew in an IKEA office cabinet - similar but not the same. My cabinet was 2.5 feet wide, 1.5 feet deep and 4 feet tall. Here’s what it looked like:
The filter and fan blew the air out the top of the cabinet. It kept my apartment from smelling like...I think I called the smell “weed and old gym shoes.” Once you plants start to flower they will have a strong smell to them. Depending on the strain, the smell may be very slight or it may be very strong. The filter and fan take care of the...mostly.
To answer a couple of your questions based on my experience:
1. You may be able to go a couple of weeks without giving your plants nutrients. But you will want to have something on hand when you do want to start.
2. I used 1/4 strength nutients for my whole grow, but my experience is that I might have been able to give more. It’s best to start off with small amounts and add more if your plants tolerate it.
3. I would follow the recommendation of your light manufacturer for the height. If they don’t say, then find someone with the same light and see what they do.
4. During my first grow, I used a 20 on/4 off light schedule, but I’ve cut that back to 18/6. The reason I did that was because I have a powerful light that will cause burning and nutrient deficiencies if I don’t. It has nothing to do with the plant biology of it. In fact, autoflowering plants don’t need to have any darkness in order to use the sugars that they during from photosynthesis. I just like giving my plants an opportunity to rest from all the photons I’m raining down on them.
5. Finally...I would just stick with your one light for this grow. See how it does. It may be more than enough light for your grow space. If, after this grow, you think you need more light, you can go out and get some more lights.
You should always feel welcome to come back and ask more questions if you have them. @archie gemmill reads everything. I mean every. thing. He’ll set you in the right direction.
By the way, here’s how my first grow finished:
