Testimonials

We became interested in hydroponics after visiting the Epcot at Disney and seeing their (CropKing) NFT system in a behind the scenes tour. After looking into it we saw the Growers Workshop that you offered. The best selling point for me was the level of support and assistance offered from your company.
Matt Holloway, Bay Water Greens

After moving off the family farm and living in suburban Washington DC, I spent some time researching contemporary agriculture online and came across CropKing. We appreciated getting to know the Brentlingers, Jeff, and the rest of the team and liked the personal touch of the smaller family business environment.
Ryan Ehst, Butter Valley Harvest

CropKing is simply the best. From superb equipment and supplies to outstanding customer service, you and your students will be hydroponic gardening like pros! My students immediately became passionate about hydroponics allowing for lifelong learners improving food security. If you are looking to get into hydroponic/aquaponic growing, look no further than CropKing!
