36 x 12 x 3 in. - Classic Grow Slab - Stonewool - Grodan 713015

Works great as advertised would buy again

The plastic around the item came torn and I had to fix it.

Works as described. Will be buying again.

Meh

Works as it should. Very easy to cut with scissors. Very economical in this form.

Although this was a genuine Grodan slab it showed up bare naked. I didn't mind that it was smashed in one of the corners but one of the the purposes of going hydro is to keep things clean.After removing the wrap and thoroughly rinsing with pure water I left it out in the sun for a week. No problems.
