Big or Small, Size Matters! In this side challenge, there are two ways to win: go big or stay small! Start your Autos on 4/20, and at the end of June, we will collect submissions for the Size Matters Side Challenge!
Prizes!
Mars Hydro is our Prize Sponsor!
- The Biggest Auto Flower Plant will win a new Mars Hydro FC-4800!
- The Smallest Auto Flower Plant will win a new Mars Hydro FC-E3000!
The Mars Hydro FC-4800 is an LED bar-array fixture designed for 4’ x 4’ coverage. It uses top-quality components and Samsung LM301B diodes. The FC-4800’s design and diode distribution allow it to spread high-density light evenly across the canopy, providing optimum lighting for all stages of plant growth.
Check out Dr Coco’s test report of the similar Mars Hydro FC-E4800 for more information.
The Mars Hydro FC-E3000 is an adjustable LED bar grow light designed for 3’ x 3’ coverage. It uses more than 1100 Bridgelux diodes to deliver light uniformly across the canopy. The FC-E3000 is also incredibly efficient. Because of its price and performance, the Mars Hydro FC-E3000 is among Dr Coco’s top picks for 3’ x 3’ grow lights.
Read Dr Coco’s full FC-E3000 test report for more information on this fixture.

Featured Video
LEDs are the Present and Future of Horticultural Lighting! However, there is a lot of misunderstanding and misinformation about horticultural LEDS. In this video, I do a deep dive into the science of horticultural LEDs. I explain the Physics of Light Emitting Diodes and the latest horticultural science about photosynthesis, spectrum, and plant development, including cannabinoids. I also appear in person, on camera for the first time ever in this video!
