Good to see you Rhizome.....I may be correct...but it's not very scientific is it? I'm the laziest one of all.....I don't even want to do test again AND I'M NOT EVEN THE ONE DOING THE TEST.

Great idea about the media test though.....that hydroton really drove me up a wall. I am using the higromite and for some reason it seems alot HEAVIER than I remember. But my seedlings are doing much better in it than the hydroton so I shall suffer the extra work in the name of love.... and future bioassays :thumbsup:
