This Hydroponics Store goes above and beyond in providing quality products and service. I started visiting their store about a year ago to obtain as much information and needed products to start up my Hydro Green house (I knew nothing about it). They are very friendly, and helpful as well as providing quality products. I am buying my PH lowering acid, as well as starter grow mediums for my seeds, and whatever else I may need from their store. I have had my plants growing about 9 weeks now, and harvested lettuce, basil, cilantro, chives and carrots. I am also growing Big Boy Tomatoes (currently the plants are about 5 feet tall, with at least 20 tomatoes forming); broccoli (plant looks great, but no sign of broccoli yet), watermelon (individual size, several are forming), sweet bell peppers (few blossoms), summer squash (I have picked a few of the summer squash, although they are not full size yet); cucumber straight eight (picked one, and others are forming), and cantaloupes (I am not sure about the cantaloupes, they are almost growing like a weed (HUGE!), I have trimmed at least 3/4 of a large trash container full of vines from this plant, lots of blossoms, and small cantaloupes forming, but a lot have fallen off, seems to be an issue with pollination). The phone number listed for their store should be listed as 661-323-7333 (it is shown as their fax). You can call them and they will answer any hydroponic questions you may have over the phone. I highly recommend this store for any Hydroponic products or for information on growing your hydroponic plants.
