I been using Jack's all purpose and Jack's flower. No one raves about them, but no one hates on them either. They're a great price and last a long time. Been using them on my flower gardens, closet garden, and veggie garden.
Edit** Forgot he said something about gh products. I've been using the floralicious to go along with them, and have been running magical as well. They were both free that's why I'm giving them a try
