Shrimp Jar Lighting Options For Thriving Plant Growth And Happy Shrimp!

Let’s start with natural sunlight. Sunlight is free and can provide energy for plant growth. However, direct sunlight can quickly lead to algae growth in shrimp jars, especially if the jar is exposed to hours of sun daily. If you decide to use sunlight, try placing your jar in a spot where it only receives limited exposure. Not everyone has a window with controlled light, though, so I prefer artificial lighting to avoid algae and maintain consistent control over light intensity and duration.

The first artificial light I tried for my shrimp jars was a small, budget-friendly clip-on light. Despite its compact size, this light successfully supported the growth of plants like Java Fern, Hygrophila Polysperma, and Rotala Rotundifolia. This clip-on light includes 10 white and 2 blue LEDs, which support photosynthesis since blue light is well-absorbed by chlorophyll. Though some early studies suggested blue light might inhibit growth, more recent research shows that when blue light is used with white light, it promotes compact growth with thicker leaves—ideal for shrimp jars. While this light was a great starting option, it lacked adjustable intensity, leading to algae growth in smaller jars, so I eventually moved to other lights with more control.

Next, I tried an indoor grow light, which includes white, blue, and red LEDs, often recommended by other aquarists. Red light aids photosynthesis and supports more robust plant growth. Unfortunately, my experience with this grow light was underwhelming. The lack of wattage and lumen information made it hard to assess its power, and it seemed underpowered compared to the clip-on light. This light struggled to support submerged plant growth, so I used it more for emersed pothos. Another drawback was the built-in timer, with only three, nine, and 12-hour settings. I’ve found a six-hour photoperiod works best in my setups, so the limited timer options made it hard to achieve the right balance. While it looked promising, it didn’t provide the strength and control I needed.

Desktop lamps were another option I considered but haven’t personally tested. Desktop lamps are popular because they’re affordable, but they aren’t designed for plant growth, so their PAR ratings can be inconsistent. Without features like a timer or proper light balance, they’re a riskier choice for growing plants underwater. While some aquarists have had success with specific models, I decided to skip desktop lamps, as some models are priced over £30 and lack key features for optimal nano tank lighting.

Finally, I want to talk about my favorite option for shrimp jars: the Hygger clip-on light. I’ve used this light in all my shrimp jars, and it’s consistently delivered excellent results. The Hygger light has clearly stated wattage and lumens, three lighting modes (white light, full spectrum, and blue+red), a built-in timer with options for six, nine, and 12-hour photoperiods, and five intensity levels. I prefer a six-hour full spectrum setting, and the adjustable intensity has helped me keep algae in check without compromising plant health. This light fits my needs perfectly, and I’ve added more of them to expand my shrimp jar collection. The newer model now includes an easier-to-use clip, resolving my only minor issue with previous versions.

This light has helped my plants thrive across multiple setups. In my 200-day-old Walstad shrimp jar, Rotala Rotundifolia is growing so well that it’s spilling out of the jar. Even in a two-week-old pearlweed setup, I’m already seeing healthy new growth. With its affordability, range of features, and effectiveness in promoting plant health, the Hygger clip-on light is, in my opinion, the best lighting option for shrimp jars on the market right now.
