Looking to get some extended growth and time on rooted cuttings before I transplant them to their final 5 inch hydroton pots. They are presently in Oasis cubes. I have found it very hard to keep them really happy in Oasis cubes for too long and was looking for some more input/ideas on this. Was thinking about putting the tray over another tray of hydroton perhaps.... Not sure honestly. One guy I bought some from had is cubes over a bed of Vermiculite or Perlite I beleive and his were very large like 10-12 inches.
