drop your light. switch to a blue spectrum bulb, loose the tin foil around the cubes until they are twice that size and replace it with a white plate with a cut out for the stem"kinda like a closed pac man mouth" the plat needs to be cut down and not be of a material that will gather moisture,card board is a no no.complete a form and come back. you will get many more answers once that has been finished. i personally believe its your lighting.drop it down....
