3-4 weeks after seeding young plant is planted. During harvesting, cut out the larger leaves and allow the smaller ones to continue to grow in 

                 

     

             

the machine. After the first harvest, you can continue the harvesting method weekly for the next 3-4 weeks without the need to re-seed.

         C2. Sprout Process

3-4 sprout harvests and each harvest cycle is 7-10 days. Enjoy your maximum planting capacity. Refer to 

user manual
