I am just wondering if a LITTLE bit of light entering the dwc bucket is ok? I know it can cause mold etc.. The lid I made doesnt fit completely flush with the top of the bucket, its made of wood, and is slighty, slightly warped. It has about and inch over-hang on the bucket too. maybe i'm being a little parnoid but i just started them in the buckets. O and the bucket itselft is completely light proof... What do you guys think?
