Paragone instructionsay to repeat 2 or 3 more time... so 15 day on 5 off, 15 on 5 off, 15 on, five off... and optionally one more time 15 on 5 off. And they estimate you will need one kit per 15 days, but I found I have just enough left over from my first round to do a day on my second round.
It is an easy product to use and I did get results -though nothing dramatic yet. Jus some pin round and brown worms and a "corn" creature.
Good luck
