FAQ - Find answers to some of our most asked questions
How high above the plants should I hang my lights?
Light intensity increases the closer the light is to the plant. However, coverage area decreases the lower you go. To maximize intensity and coverage, most plants do very well when lights are hung 12-18” from the plants. A general rule of thumb is to hang the light higher for plants grown for foliage and closer for plants grown for flower and fruit. Heres a video explaining how to best hang lights
How do I hang the light?
Our 17” and 33” lights come with vertically adjustable eye bolts. There are many options to hang them depending on your site. It can be as simple as using string with cord locks and plant hooks to hang them.
Ratcheting adjustable grow light rope hangers are a popular choice. If you are growing on a baker’s rack, you can hang them directly to each shelving unit. Our Garden in a Box kit comes with string and cord locks.

How many hours should I run my lights?

What is Passive Hydroponics?
Passive hydroponics is a simple soil-less way to grow plants that does not require pumps and a lot of specialized equipment to circulate nutrients. In our case, we practice the Kratke method that uses a container filled with nutrient water and relies on air around the top of the root zone. LINK
