I am having trouble germinating my seeds... Just a little background, i have a simple hydroponics system, (pots hang in the bucket, while a tube pump oxygen in the reservoir) which i purchased a few years ago and had good results, but recently i have been having problem germinating my seeds. Previously, i would put my seeds in rapid rooter plugs and pop them into my system where the seeds would germinate in theplugs, but recently i been having problems doing the same thing. I don't know if its because i changed strains.... Any suggestions are input would be appreciated.
