they are looking pretty fooked mate but if its your environment you're just going to experience the same thing cutting and swapping....why not hang de hu on ceiling? you can get digital hum and temp meters to play with . pull open the buds to check for molds and hit us with some temp recording, also you can get a gun to record the temps on the canopy
