Wearing rubber gloves and working in a well-ventilated room, sponge a small amount on, then off, to test the reaction. If the logs respond well, continue cleaning. Other cleansers, such as Simple Green or citrus cleaners, may pack enough power for your needs.
1 The cost of hydroseeding at Always Green Hydroseeding depends on the seed choice. 2  Quick Lawn, which uses Perennial Ryegrass, costs $0.10 per square foot. 3  Athletic and Park, suitable for home lawns, parks and athletic fields, costs $0.12 per square foot.
Any seed type can be sprayed out of the hydroseeder onto your lawn area and within 3-4 weeks (in the growing season) you will see some growth and 6-8 weeks it should be ready for the first mow. Estimates of the cost difference between sod and hydroseeding, peg the latter at 1/2 to a 1/3 the price of sod.
