RMXP Farming System???

[hawwk]

Im looking to make a Harvest Moon type game, but I cant find a Farming system that doesnt use a crapload o variables and switches. is there any script that can allow many types of seeds to be planted, while they grow at a rate unique to each plant, depending on type of plant and date planted? i have a good day/night/date system (minutes, hours, days, seasons, and years)

anybody? I've checked chaosproject, rpgrevolution, here, and all over google but all i can find is http://rmrk.net/index.php/topic,31724.msg390173.html#msg390173 from Grafikal which is close but i need somethin without alot of variables and switches for each plant.
