Purchase the turntable and different records. When played, the records will give a 2x to 6x experience point multiplier. Sell the weed while the music plays. Also try using the punk rock track gives you a 4x experience multiplier but lasts a minute longer instead of the shorter songs. To maximize this trick, buy all the customizations to keep your customers making transactions to gain both experience and cash.

Reach level 11 and aliens will appear. They will offer to advance you to the next level, but at a cost. To make their offer most effective, do so after gaining a level and not when you are close to leveling up. Tap the "Warp to the next level" choice to pay them $500 to for an instant level up. Note: They will reduce your experience points if you refuse them. To do avoid this, purchase the painting from Mary the artist then refuse the aliens' offer. They will steal the painting and leave your experience points alone.

Repeatedly plant weed and grow it instantly by advancing the time on your device. Then, set the time back to its true value and sell the plants to convert them into experience points.

It is possible to get three full harvests while playing one single vinyl record.
