Welcome to Grow Big Supply

Founded in 2011, Grow Big Supply was originally 800 square feet with little more than the owners used gear and the desire to set themselves apart from normal hydroponic retail.  With little capital (read; none) to purchase new equipment, we initiated the country’s first, and only, consignment equipment sales.

With a few posts on Craiglist and word of mouth from grower to grower, our inventory grew quickly to where we had to expand our tiny 800 square feet to 1400 square feet, then 5000 square feet, 10,000 square feet and with the opening of our latest warehouse, we became a 38,000 square foot hydroponic mega store with the latest technology and the most innovative products on the market.

Grow Big Supply now serves customers 24 hours a day, 7 days a week, 365 days a year with no plans of slowing down. From our large selection of products, our graffiti competitions, Solstice parties and our weekly Industry Cocktail Mixers (every Thursday!) we’ve got something for everyone.

Come visit our retail location at 4501 Wynkoop. We’re the huge, bright yellow building off of I-70 and Brighton. We guarantee you can’t miss us.
