I thought my Walmart didn't carry it too. Asked the sales help and wondered around the store and came up with nothing. I went home and called a few Walmarts and was told that they didn't carry it, wtf?!
Well, I was in Walmart shopping for other supplies and just happened onto the perilite - for some reason the Walmarts hide the perilite deep in the gardening section, not outside with most of the soil and such. Look over where the Seed Starter trays are, you'll find it there and it's only $2.78 for the Schultz 8qt bag, which has no additives like the MG perilite I picked up at Home Depot. I picked up 7 (which was all that they had) of them a couple of weeks ago.
And now after switching everything over from DWC to Hempy, I am totally out! I ordered a huge bag - 4 cubic I think, from my friendly neighborhood Hydro Store and can't wait for it to come in! Last night I took like 40 clones from my ladies that had been flowering for only 2 weeks and in a few days, I'm gonna need more!
Anyway We TaRdED, it's probably in your Walmart hiding just like mine was...
