Mirror to reflect light?

I've read that the red mulch is effective only in the first 20% of growth of tomatoes and melons. I purchased a roll of "red mulch" but decided not to use it since it didn't allow rainwater to penetrate it like most landscape fabrics do. Essentially, red mulch is non-porous sheet of plastic, not unlike the plastic used in garbage bags.

In a cold frame you would certainly be in the first 20% of growth stage. I am not talking about mulching the seedling with it, but putting a film of it between the mirror and the seedlings. This would diffuse the direct sunlight reflection and send down the red light waves intensely.

I agree white would work better. and not cook your plants.
