I recall a "doctor" who came on PT and started demonizing the ag grade ferts Mr. Watson sells, in the ensuing discussion I believe it was well establsihed that were absolutely no dangers in using ag grade ferts and absolutely no benefit in using lab grade ferts. I also do not recall ever hearing of anyone experiencing negative effects from using ag grade. I tend to catergorize this topic in with other debates like "fish friendly" pond liners vs. roofing rubber, Mac v PC, Ford v Chevy and of course Canon v Nikon. I imagine the purists having a stroke when someone says they use Jobe's Plant Spikes :P -----Original Message----- From: aga-member-bounces@thekrib.com [mailto:aga-member-bounces@thekrib.com]On Behalf Of plantbrain Sent: Thursday, December 29, 2005 2:23 PM To: aga-member@thekrib.com Subject: [Norton AntiSpam] [AGA-Member] RE: Madagascar Lace plant So who really uses the 80$+ lab grade?:) What does that afford us?
