Search for "physan 20" at google. You'll get a ton of hits. I just bought
a quart of the stuff very reasonably. It is available in smaller quantities
and you can use it for more than just plants.
Good luck,
Garland

Where do you order this? One place wanted $2 more than quart cost? Is
this
usual? for 6 plants I don't think a gallon is practical.
