Heat??

[Pineywoods]

Excuse my ignorance but I'm new to all of this but very interested in it. I'm in Florida and am wondering what the effect of the heat will be on plants growing in a hydroponic system? I have figured out that I'd need to bury the reservoir but would this be enough to beat the heat or would I need to grow in a greenhouse with some type of swamp cooler when it really heats up?
