Holden vehicles, in addition to nameplate, are designated by a series code. For example, the 1971â1974 Holden Kingswood has been assigned the series code  HQ , and the 2002â2004 Holden Commodore,  VY . Often these series codes are not arbitrary.In the case of the VY above, the V stands for the GM V platform that underpins it.he VY series of Holdens were not restricted to the Commodore; VY Berlina and Calais cars were also marketed.
Water the grass seed for 5 to 10 minutes immediately after seeding. Set the sprinkler timer to water the grass seed 5 to 10 minutes three times a day, beginning before sunrise and ending in midafternoon. Continue this cycle for one week to 10 days or until seeds sprout. Check for puddles, runoff and dry spots in the soil.
To measure how much water your sprinkler system puts out in a set amount of time, place tuna cans, rain gauges or straight-sided coffee cans around your lawn. Turn on your sprinkler and let it run for 15 minutes. After turning off the sprinkler, use a ruler to measure the depth of the water collected in your cans.If it's 1/4 inch, you need to run the sprinkler twice as long, or 30 minutes, to spread 1/2 inch of water on your lawn.ost lawns need at least 1 inch of water per week, so if you plan to water twice a week, you must know how long it takes to spread 1/2 inch of water over your lawn.
