Who We Are

SLIP is an innovative company comprised of St. Louis entrepreneurs who envision a healthier and more abundant future for our city through plant science and technology. Hydroponics has created a local resource for fresh vegetables, fruits and herbs in major urban areas across the country, and SLIP is proud to make farm to table produce a reality for the St. Louis Community.

What We Do

Supply SLIP's locally grown produce to local restaurants and grocery stores

Interact with youth groups to educate the community on the benefits of hydroponics indoor farming solutions

Research and Develop innovative ways to grow produce indoors

In order to continue supply and keep up with demand from larger restaurants and grocery stores, our goal is to expand to a larger production warehouse and thus expand our reach into the St. Louis community. Find out how you can help bring local produce into the community.

Hydroponic set up
When we create urban agriculture, in which vertical farming plays a large role, we will have no more agricultural runoff, because we will recycle water in a closed-loop agricultural system

Hydroponics 101

Hydroponics is a method of agriculture enabling us to grow plants without soil. Plants need nutrients to grow and thrive, which is easier with hydroponics in a controlled, indoor environment without the stresses of harsh weather and pests. With hydroponics the plants are grown in an inert growing medium and a perfectly balanced, pH adjusted nutrient solution is delivered to the roots in a highly soluble form. This allows the plant to uptake its food with very little effort as opposed to soil where the roots must search out the nutrients and extract them. SLIP uses a recirculating vertical Nutrient Film Technique (NFT). Our vertical growth system allows us to grow large amounts of produce within a very limited amount of space.

Hydroponic System

The process

The nutrient film technique (NFT) is a hydroponic growing technique where a small, shallow stream of nutrient-rich water is recirculated over roots through a channel, gutter, or tube.

  • Recirculated water reduces environmental footprint

  • Saves on water costs

  • Promotes faster growth cycle


The equipment

  • Vertical Growing Modules
    • Seedlings are transplanted into PVC towers and fed targeted liquid nutrients through constantly moving water
  • Home-Made Lite Rack
    • Emits custom color wavelength to help plants grow more effectively
  • Timers and Sensors
    • Controls watering/feeding cycles to promote faster and more vigorous plant growth
