hard wood planks

Im struggling to understand how to make hardwood planks can somebody help me out please??

you need to build a hardwood sawmill and you also need hardwood cutter and hardwood forest than you can make hardwood planks

you can also use provisions house to create 50 hw planks at cost of 250 fir wood planks

For hardwood production it's important to place the woodcutter next to a hardwood tree. To reduce traveling. Best setup is: 2 Hardwood cutters, 3 hardwood foresters. and 2/3 hardwood sawmills. Also place a storehouse very close to your hardwood creation industrie.

thanks,i found out i have to be level 17 to start making hard wood and i was only at level 16 when i asked the question but thanks for the other tips aswell
