Welcome to the Forums PopperFart,

You should gradually give your VFT more light to get it used to it. VFTs do best with lots (6+ hrs.) of sunlight. You should also get it used to being without the cover gradually. It's probably used to the higher humidity under the lid. Don't leave the lid covering the plant while the plant is in direct sun for a long period or it will get cooked.

It might not hurt to rinse the soil thoroughly a couple times to flush out some of the fertilizer and minerals that may have been in the water they used at the store.

I think your plant will handle being outside pretty good. I live in Colorado and grow my plant outside from late Spring to late Summer/early Fall.
