Automatically Harvesting Magical Crops

[willhoot]

I hope this is the best place to ask this

 

I am looking to make a system to automatically harvest crops from the magical crops mod. I have been recommended to use turtles from computer craft but when looking at the API I couldn't find a command to check if the crops are fully grown is there one? Is there a better mod to use to harvest? I have heard thelmcraft golomes work but they are laggy and unreliable. I want to use steve's carts 2 but aparently the farmer doesn't work with non-vanilla crops. 

 

Thank you in advance

 

PS: I am using the Serendipity Unlimited pack but I am using it single player (on the multiplayer turtles are banned so their forums aren't really helpful for turtle questions)
