I looked on homedepot, did you get the bricks or the bag. I seen a site with a min of 300$order so after shipping they would be 11$(7$ before shipping)each. But right now I don’t need that much coco esp if I choose to switch to hydroton in 6 monthsBought 5 bricks online at Home Depot along with charcoal, epsoma blood meal, epsoma lime, epsoma bone meal, big ass bag of perlite, organic EWC, mycor fungi, guano and kelp organic ferts and all were very cheap imo and free shipping to the store with curbside pickup. Just my 2 cents. Also a helluva lot cheaper than from a grow site.
I love my organic home mixed organic soil and my lil darlins love it too after adding ACT.
