In my first year of uni I had a 3foot tank and a small 3/2/2ft poly house for my plants, the rest I had to leave at dads, so I made an automated greenhouse.
Second year I moved to a larger place and got my (my as it is still current) 12/8/6-7ft polyhouse, a cattle trough pond, 3 small ponds (50-70L), that tank, plus another (but most the collection is at dads as he is just 1-2hours away).
Also you will be chasing cheap water trays (if you have many sarra/drosera/utrics that grow outside, I use storage boxes, they are cheap and very effective.
Some uni's won't let you have a tank as it can spill H2O, but you can have a poly or tank outside of the room, their main issue is the mess it "will" make inside (my uni is the same and I have a friend on campus who met this issue), alternitavly find someone in the area that has these plants (or something close like if you have neps who has orchids) and ask if you can keep a few there.
But I would be carful idiots don't touch or steal anything.
