So many options for the hydroponic enthusiast. Stay away from "Howard" and www.homegrown-hydroponics.com. He shipped broken items and didn't fill the entire order. Not shockingly, the most expensive part of my order was never filled. www.homegrown-hydroponics.com (the hyphen is key) is rated "F" by the south Florida Better Business Bureau. I should have researched before I decided to do business with Howard Birnbaum. His company has also been reported to google because they spam search engines to increase their web presence. To top it off, it was the worst costumer service I've ever encountered.
