UPDATE APRIL 2020:  We are operating curbside service only. We are open. And we are keeping things as clean as possible. We’re taking care to wipe surfaces between customers to ensure your safety as well as the safety of our employees. Please do your part by only making a trip for essentials and maintaining proper social distance at the curb.  Let’s do everything we can to flatten the curve.

Update 2019: Steep Hill no longer services DC, having moved their operations to focus exclusively in Maryland.  We are actively seeking another content testing lab to partner with in the District.  In the meantime, please take advantage of our Farmer Freeman EZ XY testing on-site anonymous dropbox.

Not only can we help you determine whether your plants are male or female at an early age with samples of their genetic material, we also sell equipment required for your processing needs, including trimming machines, vacuum ovens, bubble bags, and Magic Butter machines.  We recently added a compact model pre-roll cone machine to inventory, rated at 100 cones/90 seconds.  And we’re at the cutting edge of digital security for customers in an industry with some concerns:  check out our selection of Faraday bags for preventing geolocation pings to your business phones.

Last year our team installed approximately 40,000 hydroponic plant sites, in about 15,000sf of greenhouse space, for large institutional and educational customers in the District, increasing food security in urban “food deserts” via the “Food Hubs Program.” We are preferred vendor for horticulture program procurement in school districts in both Virginia and DC.   We have experience with a wide variety of system designs and at every scale, from hobbyists to licensees.  From equipment installation to processing and marketing, Cap City’s consultants give you access to all aspects of the industry.

Capital City Hydroponics has been Washington DC’s premier hydroponic supply shop since 2010, and Capital City Organics is our new venture to provide a retail showroom experience for our customers. We pride ourselves on providing the urban grower with the latest in high quality equipment and products, and proper advice on how to use them. From the latest LED lighting technology to organic nutrients and everything in between, from appliances to accessories, Cap City Organics is a one-stop shop for all of your hydroponic & organic needs.  Don’t hesitate to ask about your preferred products– if we don’t stock it, we can get it!
