Dear Bill, Thanks for the very interesting information. What does PB stand for? and the 40 stand for Litres? I suppose that thes bags are the same as those used in tree nurseries. Ar there no problems to handles these bags? I suppose that the reason to use these rather then plastic pots is the price? (or are there other advantages) Kind regards -- Lauw de Jager BULB'ARGENCE, 30300 Fourques, France Site: http://www.bulbargence.com/
