3rd pic is new system installed today. 6 mil clear plastic held down with small pieces of
wood tacked with a brad nail gun. For best results, the plastic needs to be sealed in order
to keep in the moisture and heat. Also, if the soil is dry, water should be sprayed on the
soil or grass before the plastic is laid to create the hot steam effect.

The hotter the direct sun, the quicker the grass will be killed along with some grubs and
borer pupae. The sun needs to be nearly directly overhead for the best results.
