Leaves overlapping each other and getting wet

I've noticed this a bit lately. My plants are nice and bushy and are obviously transpiring alot because where one leaf sits on top of another, there is a water build up which is uncovered when i move them apart.

Is this going to cause a problem? Should i have a fan blowing directly onto the plants to fix this?

you should for sure have a fan in there blowing on the plants, It also helps stem strength greatly......

I do have a fan in there, but its a bit too low i think.

Cheers i thought that might have been all i need. I'll get onto it.
