clones in DIY aero cloner not lookin so good ?

[Zandor]

so I just picked up a 30 gal GRAY Sterilite tub for a 36 clone site should I do something to the top ? like paint it white for more reflection or just leave it be ?
Thanks

If you put plastic over the top I see one problem with that. Mold would grow between the lid and the plastic and that could cause you problems.

With the gray or even the blue tubs; you are fine to use it just as it is.
