I would not store any camera equipment in direct sun. Sun can cause plastic to age faster and become brittle, never mind excessive expansion and contraction. Amazon: Search - Camera humidity control cabinet.

Unless you live in an extremely humid climate or improperly store your equipment in a damp cellar or other place where mold is likely to flourish, chances are, your lenses will not suffer from mold growth. If your equipment gets wet in the field or is constantly exposed to inclement weather conditions, you should employ protective measures such as the use of polyethylene bags, camera hoods and special cases. Dry of wet gear promptly. Aviod condensation from extreme temperature shifts. Use Silica-Gel for long term storage in humid environments. Reactivate the Silica-Gel periodically by heating it, not your equipment! Do not bake your gear in sunlight!

Placing the lens once a week for an hour or so in sunlight should be enough to keep fungus at bay. Or simply use the lens regularly. A heavily used lens is far less likely to develop fungus than a lens that is left untouched and packed up in the dark for long periods.

Funny, I was going to ask if anyone else kept silica in their bags.

Without knowing more about the OP's environment, this pretty much covers it.

I Don't know if it works I live in high desert but lots of pines trees I am only 30 minutes to turn off of the north rim Grand canyon. But i get gel pack in many items heat up and put a few in my bags and I don't think i need to worry about mold but you just never know . I make sure I wipe down even when I get in snow. And I use a 7D I am good to my equipment. Does anyone know and can tell me where mite be a good place to sell a film camera like a EOS 1n and a A2 both in excellent condition.

Heat is also said to affect the glues used to hold lens elements together, at least for older lenses. At one time Pentax made lenses that included a mildly radioactive material, and those lenses tend to turn yellow over time; a cure is to expose them to UV, but we're warned not to put them in sunlight too long, because that might cause the internal glue to melt.
