spraying the roots with water will not harm the plant at all..
I suppose you could, although there is no reason to..Can't I just keep the dirt on the roots?
I would rinse off all the dirt just to be sure all the new media is nice and pure..
there could be mineral contamination from those white rocks..
yep..that would work fine.Also, is a glazed clay tray ok to use?
as long as the part of the tray holding the water is fully glazed..
