Devon, you gotta take some readings man. Invest in one of those nice thermometer/hygrometer combo units on ebay or get the exoterra one (The one I use). You can get readings of maximum/minimum temps/humidity at a location. THis way, you can do your homework before getting a plant.
Another option: depending on how small the plant you get, you can grow it in a small 2.5 - 5 gallon tank and believe me.... for that size...ice packs work very very well in cooling down.
Also, this is how I successfully grew many highland neps for 2 yrs: greenhouse enclousure...ice packs (basically frozen water bottles) suspended on the shelf above the neps. Cold air falls...so, grow the highlanders close to the floor, place cold frozen bottles. Works very well. I had a pic of that somewhere...must be on my other laptop back at home. I had successfully grown a villosa that way even through the summer. This a perfect affordable idea if you want to get into highland neps. This greenhouse is only 30$ from canadian tire..and if you can manage to persuade your parents... you can do very very well with it for atleast a couple of years.
