Yup rooting pwder is a much better hormone then gels. I have tried side by side results with so many people getting on the gel wagon when they started to come out. I get 70% success with gels and about 98% with powders and powder roots show 3-5 days gel 7-14 days. Now back to the question avoid jiffy peat pellets like plague. They have jacked up ph holdings,Dont grow well,Seem to cause sprout failures and make a mess in any hydro application. Use rockwool or soiless mix or if soil growing germ the seeds then right into soil.never peat pucks
