wow, well I have been trying to make my own now for MTHS !! I an only find the right clay at the hobby lobby here, in s.c. , we dont have the other stores you guys /gals have metioned. ... and a 5lb bag/box was like 20.00 !!! way too much clay , ie> I* dont need that much !! and way too high on the price for all that red mexican clay I wont be needing !!!! So I am going to a few places at the beach when I visit there for a night on the 5th, me & the BF are going to myrtle beach *( 45 min away ) for a night of relaxation and walking on the beach, visiting the aquarium there, and other neat fish stores, and neat places. I know they have a micheals, I will look online for any locations of the stores you guys have mentioned, I really like the 7.00 deal, that sounds a little more fair, but as I am spending tons on root tabs every other mth, I guess ethier way its a saving $$ .. really . I use dry ferts as well, but I like to give my root feeders a xtra treat' every other mth or so . hurts no one, and they jump up in size every time !! lol ~ thanxs for the recipe , I will be using it !! ~~~~~~~~~~~
