I need some assistance, please. My 12-year-old stepson has recently moved to a new school and has had thrust upon him the necessity of participating in a botany science project. His task is to provide the "hydroponic powder nutrients." One brand name suggested was HYPONEX. I have been unable to find anything of the sort locally. Can anyone tell me where I might find this? It doesn't have to be the particular brand mentioned. He just needs some kind of hydroponic nutrient powder. Tomorrow. Thanks!
