If you're a serious outdoor, indoor, or greenhouse gardener/grower do not shop at Home Depot or Lowes, I repeat do not shop at Home Depot or Lowes. Home Depot and Lowes are general hardware stores, they do not carry high-quality or hard to find specialty items. For high-quality specialty items, you need to go to specialty stores, and when it comes to hydroponics Healthy Harvest Hydroponics is defintitely one of those stores. I was looking for a hard to find soil additive, and after doing some research I found that Healthy Harvest Hydroponics distributed it. They didn't have it in stock, but they ordered it and I picked it up a couple of days later. While I was there I decided to browse around, the place looks small from the outside, but once in, I realised how huge this place is. They have just about anything you are looking for in regards to gardening/growing. I saw varying grow lights, hard to find soil nutrients, climate control devices, clone devices, greenhouses & tents, soil & pots, and plant care devices. I was very impressed with this store, and will definitely return.
