Tlsdrm do you have ventilation up through the canopy?
Is the floor of your room wet from water dripping through your buckets?

- Take all of your plants from your room.
- Clean with a mild bleach solution, rinse the walls.
- Make sure that your room is completely dry, floor walls ceiling.
- Build an Air Floor (download Weed Science: Equipment) with air inlet below floor, outlet near ceiling.
- Draw air through the canopy to eliminate mold.
It could be stagnant air below the canopy, not the humidity, that's causing you problems. A fan pushing air between the light and the canopy to reduce heat stress will not solve the problem - you need to vent the rooms air and draw fresh CO2 rich air up through the canopy. An air inlet on one side of a grow room often cause and air flow up the wall and across the tops of the plants, not up through the canopy - especially if the canopy is thick in flower.

Milk Crates make a great air floor - remember the golden rule: Be lazy, the work is already done for us and someones thrown it out.
