    Give Seedbooster Plus up to one week after rooting to protect the young plants.
    There are many different methods that all have their own advantages. A proven method is to soak the seeds first for 12 hours in water that's 23 degrees Celsius with Seedbooster Plus. Then plant the seeds in a coconut or mineral wool plug watered with the Seedbooster Plus solution. Place this under a fluorescent lamp at 23 degrees Celsius. Increase the light intensity as soon as the seeds germinate so they do not grow 'leggy', but develop into strong, wide plants.
