7月底买的R2000， validation complete了好几个星期了，一直不寄出来。之后的
R1400的$80都全部寄出来了，大家的也是这样吗？还是我悲剧了？
谢谢

当然了。不同的sprinkler，省水也不同。
另外，sprinkler的设置，省水也不同。
举个例子，sprinkler的spray nozzle的高度，对省水也不同。
大有学问。不要小看省水。一个月能省至少20美元。

If you want to conserve water, just let the grass go dormant. It will
return to life once weather cools and get wetter.

thanks.
I decide to do the following things first.
1) tree pruning. so that tree will not absorb up all the water in the lawn.
2) spraying water at midnight instead of morning. This will avoid the
vaporating.
3) reduce the frequency of mowing the lawn.
4) check and replace all spray heads.

Whatever you do, don't prune the tree. Tree root and grass root are at
drastically different depth, so tree root does not absorb water that grass
would be absorbing. The tree's shade is the only thing helping lower
evaporation right now. Pruning it would hurt your lawn, and probably hurts
your tree as well in this weather.
Definitely reduce mowing though. if your grass is still growing quickly in
a drought, you have watered too much. I would suggest you just reduce the
frequency you water the lawn. That would both save you water and keep the
grass from growing too quickly.
