I use a pipe pvc and at night I put it on the neighbors fruit trees. At one time I put them on my roses. But had a problem explaining why my roses were so damn big. Its fun to dump them on one of a bunch of plants in a neighbors yard. They go bonkers trying to figure out why only plant grow so large.
Note in Calif. lemons are only the size of grapefruit if you help muther nature.
Note I dump 80-90 gallons every 3 weeks so it a lot of fun. Down the drain is a waste of ferts.
Best was glad's 7 ft tall and 8 in flowers, gerainiums (SP) 4 ft tall, limes the size of large oranges. One thing with muther nature she has nice firm buds with hydro I love nice large firm buds.
