I take it back. I thought that I was replying to a different thread. Good questions. My apologies... Also, given that your space is narrow It doesn't appear that a vertical lights would work well.

Pretty convenient setup. You are on track with those temp / humidity estimates. You will want to drop the humidity to 30 - 35% during the last few weeks of flower. This promotes development but also reduces likelihood of bud rot caused by mold.

Yes. You can use the MH right through the first 5 - 6 weeks of flower - strain dependent.
