I dust the seeds and the root riots I use.  And here and their I dust roots threw out life time don't use in flower.  I use hydroguard more.  Seems to really work I never had such healthy roots.  That's genetics as well thanks Nirvana.  I do want some purple buds so Nirvana said all they have is GDP and Walter Nirvana says they don't have any good purple strains any suggestions?
