It's supposed to be maintenance-free. You can choose to vacuum it though. But I will recommend putting drainage cells below to keep the grass dry after rain (damp condition causes algae). I bought the grass and cells online and install them myself. Used it for almost a year and so far so good! You can google Overture and check out their prices, they're quite reasonable. Just that you have to self-collect somewhere in the east.

I am trying a small piece of artificial grass that I bought from this local online store.. $39 per sq meter. Two months down the road so far so good! You can google Overture Singapore..

Chance upon this online store in Singapore that sells artificial grass for $39 per sq meter, seems like quite good quality. The store name is Overture.. you may want to check it out.

I came across a similar thread in Green Culture SG forum. You may be able to get your solar lights from there.
