i wish i could grab that thru the screen and roll it up!
Lol, they are Grow Stones. I think the label says 17% better aeration, and maybe 20% better moisture retention? So far I am impressed with their performance. I will be doing some side by sides of Hydroton vs Grow Stones to see the difference. I have a couple hundred gallons of Hydroton, but it is getting old, and I hate the clay residue...Man those look exactly like growstones
I wonder which is "better" lol
good question Dan
GG#4 doesn't even look like it requires to be trimmed lol!
