you can absolutely do all your work in that big ass tent lol it makes all the sense to do so.. good idea!
The second question is more of a personal preference, what you're planning on doing with product sort of thing. If you have a need to transport then I would say nothing beats ziplocking 8 oz at a time and vacuum sealing either one or two depending on your future plans. I personally keep things in jars because i do a smaller perpetual thing and imo everything is better out of the jar. If you take something that's been vacuum sealed vs in a jar for 6 months there is a marked difference but it isn't really worth the trouble unless its personal/connoisseur.
good luck with everything!
