Guitar necks are tough enough, it's probably the constant changing humidity that is the culpret. as the humidity increases so dose the moisture content of the wood. as that takes place, more moisture = more sweling it may eventualy even crack. Keep all your woden instruments in a constant invirement (humidity) the same all the time, you will have better results. If you can store your guitars in a hard moisture resistant case. you can purchas at most marine supply, and some guitar stors, little packets of dry chemical moisture absorbant material that suck the moisture out of the atmosfere like a sponge. they dont cost much and will help keep the humidity constant. they will last about a month and need to be replaced. Good luck.

Welcome aboard SSP!

It's not just the humidity, but also the dryness in some areas that can wreak havoc
on guitars. Truss rod adjustments need to be done in order to keep your guitars
in top notch condition, but still, the wood itself needs some TLC too.

Trunk not good. The heat on Flagler St. will cook it.

Living in south Florida, I would NEVER keep a guitar in the trunk...I don't even keep CDs in the car. The heat melted the glue of my Velcro for my Sunpass. Keep it in the house and the office if you bring it to work.

you can't keep anything of value in the trunk of a car in florida. Pool Cues and Guitars don't stand a chance. i don't even let them in the trunk for an hour ever. Florida weather is brutal!

Desiccant packets can be dehydrated and re-used.

Spread them out in a metal pie tin or on a metal cookie sheet then stick them in an oven set to 170º for an hour. The litmus inspection/indicator cards can similarly be dried out but they only require about twenty mikes in the oven.

If you can try to keep your guitars somewhere with a stable climate, or at an area with a gradually changing one. I live in Houston, Texas and our humidity and heat is on par with Florida and other gulf coast states. I've never had problems with my guitar necks, and the air conditioning in my house is just barely passable. But I would never, ever leave my guitar in the trunk. I left my iPod in the trunk once in July and it completely died. If you possibly can, take your guitar into work with you, or just leave it at home. Or buy a cheapo guitar for as little as you can and take that one to work with you. That way you could still get some practice time in, but you wouldn't have to worry about the guitar too much.

arent necks and bodies dried and sealed?

Both the humidity and the heat can affect the wood of a guitar's neck or body. It'd definitely be best to find a corner in the workplace where you may be able to keep the guitar instead of the trunk. And as far as the humidity goes, the previously suggested desiccant packs tossed in the case with the guitar and dehydrated in the oven are the best thing to do. You don't have to pamper guitars, but temperature extremes and excessive humidity are gonna be your two biggest problems.

Don't leave your guitar anywhere you wouldn't be comfortable.

A piece of wood may have been kiln dried and sealed with a coating of somekind. you may think it's air tight after that. That would be a very bad thing. wood must be allowed to breath or it will eather dry out and disintegrate, or retain to much moisture and dryrot, and swell and contract untill it cracks open. If a piece of green wood is allowed to dry out without restraints it will twist and crack acoarding to the grane of the piece. If its held in place usually by something heavy, it will dry, or cure streight and true. Hope this helps.
----Danny,

I shold add that alltho a piece of wood has been kiln dried and is streight and trew, changes in atmospheric condetions will have a profound effect on it. ( A piece of furniture will last for centuries if kept inside. The sane piece will fall apart in notime if left out side.
