10" x 20" Propagation Tray 72 Cell Insert Use this insert to hold up to 72 rockwool multiblocks so that you don't get a mess of tangled delicate roots. Seeds started in bulk often get planted too close and the roots end up getting entangled and damage is done to the delicate roots during transplanting. This insert eliminates that risk ensuring that all your starts are healthy and vigorous.
