THE WORST leopard gecko substrate

My Review on quite possibly the worst leopard gecko substrate Corn Cob

I’m using that substrate you showed at the start. I’ve had my little chap for about a month, and I’m now considering trying to go bio-active and add some top soil of sorts. I’m using Pets at Home, but quite often use smaller shops in Bristol so I’ll try and take a look at alternatives

Is there any substrate you would recommend?
