Oh hallelujah! So it is Chicken Grit -thank you for clearing that up Al, I'm getting closer to my illusive first batch of gritty mix!. I spent most of yesterday on the phone looking for grower grit, I found "cage grit", "chick grit" and "regular chicken grit" but no one knew what I meant when I asked for grower grit (and it probably didn't help that I wasn't sure what it was!). Regular chicken grit is available at my local Arrow feed store for $6.99/50lb bag. I assumed it was the wrong stuff as they had no idea what "grower" meant. I'll go there today and just pray its granite and not oyster shells in that 50lb bag. Bummer about the Lowes/HD stuff JoJo - that was my back up plan! ...although I could actually use the remainder for a pathway if some of it would work - what percentage would you say was usable? I still need the illusive pine bark fines - now my clematis plants are taking off its a race against time to get their new pots ready! BTW Al, I really appreciate all of the wisdom you have spent so much of your time sharing, thanks to you, now every nursery worker within 100 miles of my house is looking into your mixes and the guy from the distribution center where I found the MVP Turface was very interested, he even wrote down the website and your name etc to do more research, I think the light bulb went off that they may have a whole new way to market that product. Thanks! Nik

Hi Tropic... I had had to laugh because I do the same when I go into stores looking at items. We have a commercial store called " Restaurant Depot" for commercial buyers and I always go to the utensil section.. Hubby gives me the look because I'm at the strainer section or looking at mats to use for the winter. It's amazing how we can look at an item and see the possibilities for our plants and trees. Great minds.. :-) i have many strainers and screens to use thank to seeing pictures of Al's sets of his screens that he made. My hubby made a set for me but used 2x4 so they are really heavy for me to use, but I don't dare complain. Thank you for the kind compliment!! This is one that is use for the kitchen sink. It works great too!!! Laura

You can find a smaller size of grit (for growing chickens, not adult chickens), but it looks pretty good to me. I'm using white granite grit, which looks the same but without the black/grey specks (nearly pure white).

Holden - 'developer' is the next size up from grower, and too large to be well-suited for your mix. The North Carolina Granite Corp Crushed Stone Products Product: Starter 3/32"‐1/16" Grower 3/16"‐3/32" Mixed color Developer/Layer 5/16"‐3/16" Al
