I would highly recommend Ultra Tech Vermiculite. The uniformity of their vermiculite is far superior to other sources we’ve used. Switching to their vermiculite has saved us numerous hours of sifting through vermiculite bags to remove the 30-40% fine grade vermiculite that was included with other ‘coarse grade’ products.”
