Dramm's Agitation/Aeration Bucket provides a thorough mixing of any solution. Perfect for use with an injector, the Agitation/Aeration Bucket can keep water soluble fertilizers, fungicides, insecticides and PGRs in suspension. With a flip of a switch, agitation turns to aeration. Air is introduced into the passing stream, keeping dissolved oxygen at saturation levels. Use this feature when agitating nematodes or other organisms requiring oxygen. 5 gallon capacity.
