Those 50lb tank are so fucking heavy and conspicuous. Make sure you got a story ready for neighbors (planted freshwater aquarium, draft beer tap, welding ect...). I been thinking about getting a second 20lb tank .
No ozone generator in the tent, it will hurt the leaves and take away their odor . I like to put mine next to the carbon filter, it takes care of anything the carbon filter misses, especially on humid days. Ozone is like H2o2 for the air, it has a 3rd oxygen molecule that oxidizes organic matter such as smells. The room that my carbon filter is in also has the ozone generator. The air in this room is expelled past the lights and outdoors. No plant and minimal human contact when I'm in the machine room (it's on a timer 15min on 45min off) since I turn it off while I'm in there. I use a cap ozn-1, I have used it for over 3 years and had to change the bulb once. There are inline ones too. The ozn-1 uses bulb technology, others use a sparking technology (I think). Pretty sure the ones that use bulbs are better.
Moral of the story the cap ozn-1 is powerful and can hide the smell of anything (even a house fire) but is moderately dangerous if used improperly. It could save your ass in late flower-hanging.
Planning on running zone or bleach? I have seen root rot in constant 62F water.
