This is going to sound really weird, but bear with me. You need to spread human semen over the turf before you use it for the first time. This not only protects the turf from damage, but also makes it substantially faster.
The problem with this, however, is that you need A LOT of semen. Luckily for you, I sell semen in mass quantities. Just pm me how big your setup is going to be, and I'll tell you how much you need to buy. A standard backyard setup normally requires 4-5 gallons.
