Best Aquarium Plant Trays for Planted Tank Setups
As an Amazon Associate we earn from qualifying purchases.
If you are shopping for an aquarium plant tray, the first thing to know is that none of the eight listings in this guide is a dedicated tray, so we do not pretend otherwise. What they have in common is the job a plant tray supports: helping live plants do well in a small tank. Here the work is done by light, so we compare eight lighting listings by what each states about wattage, size, mounting and controls. One of them, the Hiro Aquatics lamp, comes with a bamboo board, which is the closest thing to a tray in the set.
Quick answer
- No listing here is a plant tray. If you need a physical tray, check the product page of any tray you consider for its own size and material.
- For a small open tank with a board across the top, the Hiro Aquatics lamp includes an 8.5 by 9 inch bamboo board.
- For tanks 15 to 24 inches long, the Fluval Plant 3.0 lists a programmable day cycle.
- For fully underwater placement, three listings are described as submersible with an IP68 rating.
What a plant tray does, and why light comes up
People use the phrase plant tray in a few ways. Some mean a flat tray that holds potted or rooted plants. Some mean a platform that holds plants above or inside the tank. Some mean a planter box on the side of a tank. The pack for this guide contains none of those items, so we cannot tell you which trays are best or how to size one. What we can do is cover the other part of a planted setup that the listings do address: the light that sits over or inside the tank.
Why light? Because a tray, a substrate or a plant bed all depend on it. A plant that has a good place to sit still needs light that reaches it. The listings below describe full spectrum output, timers and mounting ranges, which are the details to compare. Our other guides on plants for a betta tank and freshwater LED grow lights go further on both topics.
How to read a lighting listing for a planted tank
Mounting type
Lights here fall into four groups: clip or gooseneck lamps (the Hiro Aquatics and the AREPK pair), bar lights that sit on the tank rim (the Fluval Plant 3.0 and the 48 to 60 inch foldable hood lamp), submersible strips that attach inside with suction cups (the three IP68 lights), and a bracket that can be adjusted in length. Each fits a different tank, so measure first.
Power and voltage
The listings give different figures: 3 watts for the two 7.5 inch submersible lights, 5 to 9 watts for the clip lamps, 22 watts for the Fluval and 34 watts for the long foldable hood. Voltage ranges from 5 volts for the USB-powered AREPK to 240 volts for the long hood. A watt figure alone does not tell you how well a plant will do, since the listings do not give plant-specific numbers.
Control and timing
Controls are a real difference. The submersible white and blue lights list a built-in programmable auto timer with three durations. The AREPK lamps list a timer that switches the light on and off automatically. The Fluval Plant 3.0 lists a programmable 24-hour cycle. The color-changing 7.5 inch light has wireless and wired remote controls with memory.

1. Foldable Full Spectrum Hood Lamp, 48 to 60 Inches
This is the longest light in the group, made for big tanks. It consists of two 22.5 inch lights that are merged using retractable brackets to form one set, suited to tank lengths of 120 cm (48 inches) to 150 cm (60 inches). It lists 5730 SMD LEDs, an aluminum case for cooling, 34 watts at 240 volts and a remote control. Three control modes are listed: all LEDs on, only blue LEDs on, and off.
The listing warns that the light is not waterproof and should not be put into the water. Its folding design is meant to reduce the chance of damage to the long lamp body in transport. It does not suit a small tank, so skip it if your tank is anywhere near the nano range.
2. Hiro Aquatics Full Spectrum LED with Bamboo Board
This is the listing closest to a tray, though it is a lamp sold with a board. The bullets say the lamp and board can be used on a nano tank, a betta tank or a potted setup. The full spectrum LED is described as mimicking natural outdoor sunlight to help plants grow, and the lamp swivels 360 degrees, with a lens on each bead to widen coverage. The bamboo board is described as waterproof and insulated for strong temperatures and measures 8.5 by 9 inches.
The lamp lists 5 watts at 110 volts, weighs 2 pounds and measures 13.5 by 13.5 by 13 inches in black. The listing does not say the board holds plants or substrate, so treat it as a base for the lamp and a covering surface rather than a planting tray.
3. Fluval Plant 3.0 LED, 15 to 24 Inches
The Fluval is named for planted tanks and lists a 22 watt output for tanks 15 to 24 inches. It has six unique band waves for full spectrum results, a programmable and gradual 24-hour light cycle (sunrise, midday, sunset and night), optional preset habitat configurations such as Lake Malawi, Tropical and Planted, and 120 degree light dispersion for uniform coverage. It weighs 0.55 kg and its product dimensions are 2.5 by 15 by 0.63 inches.
It is the strongest match for readers who want a one-piece, preset-driven planted light for a mid-size tank. The listing does not mention plant trays.
4. 7.5 Inch Color Changing Submersible LED
This is a small submersible strip at 3 watts and 230 volts, weighing 196 g. The listing says it meets IP68 waterproof standards and works in both salt and fresh water. It has wireless and wired remote control with memory, so you can switch on and off, adjust brightness and change color. The listing calls it a dimmable full spectrum RGB light, good for plants and fish, and widely used as a multi-color decoration.
It suits a reader who wants accent color inside a tank or terrarium-like setup. The color-changing design means it is more of a feature than a core planted light according to its own bullets, which stress decoration.
5. 7.5 Inch White and Blue Submersible LED with Timer
This strip offers three modes: blue, white, or white and blue. The listing lists 7000 to 7500K white LEDs and 460 nm blue light that it says is sufficient to grow underwater plants, adjustable brightness, and a built-in programmable timer with three durations. It is IP68 rated for underwater use. The kit includes the light, suction cups, a power adapter and a controller. It lists 3 watts and weighs 0.19 kg.
Use it as a main light, accent light or replacement, as the listing says. For a tank with plants close to the glass, a small underwater strip can be placed near them, though the listing does not discuss placement.
6. 15 Inch White and Blue Submersible LED with Timer
The 15 inch version shares the three modes, timer and IP68 rating. It lists 7 watts, 110 volts AC, 212 g, and includes two suction cups, a power adapter and a controller. Its size makes it a better match for a tank where a 7.5 inch strip would leave much of the tank unlit.
The product dimension is 15 by 2 by 2 inches, so it is slim. Choose it over the 7.5 inch version when your tank is longer than about 15 inches and you prefer a submersible strip to a rim light.
7. AREPK Full Spectrum LED, Under 7 Gallon
This gooseneck lamp is listed for aquariums under 7 gallons and also for terrariums, bonsai and moss. It lists 9 watts at 5 volts, a timer that turns the light on and off automatically, a bamboo board and a 50 inch USB cord, with a flexible gooseneck that turns 360 degrees. The product measures 13 by 13.3 by 21.5 inches.
USB power makes it simple to place near an existing outlet or power bank. The listing says the full spectrum LEDs imitate outdoor sunlight to help plants grow.
8. AREPK Full Spectrum LED, Under 3 Gallon
The smaller AREPK keeps the same format at 5 watts for tanks under 3 gallons, weighs 0.89 kg and measures 9 by 8.6 by 15.7 inches. It shares the timer, bamboo board and flexible USB gooseneck bullets. Choose it for a very small tank or a bowl-sized scape.
How to pick for your setup
- Measure the tank length and depth. Match it to the stated range: under 3 gallons, under 7 gallons, 15 to 24 inches or 48 to 60 inches.
- Decide between over-tank and underwater. The long hood is explicitly not waterproof. The three strips are IP68.
- Choose your control style. Remote, timer or preset cycle: the listings differ.
- Check the plug. Voltages range from 5 to 240 volts across the group.
- Shop trays separately. If you need a tray, look for a listing that states its dimensions and material, and compare that to your tank.
Mistakes to avoid
- Assuming a bamboo board is a planting tray. The listing describes it as a base for the lamp.
- Putting a non-waterproof light underwater. The long hood lamp listing says not to.
- Buying by watts alone. Fit, controls and spectrum details matter too.
- Using a long light on a small tank. Mounting ranges exist for a reason.
FAQ
Is any of these an aquarium plant tray?
No. The listings are lights. The Hiro Aquatics lamp includes a bamboo board, but the listing describes it as part of the lamp set rather than a planting tray.
Which light is waterproof?
The three submersible strips list IP68. The foldable hood lamp says it is not waterproof. The other listings do not state a waterproof rating.
Which has a timer?
The two white and blue strips list a built-in programmable timer with three durations. The AREPK lamps list an auto on and off timer. The Fluval Plant 3.0 has a programmable day cycle with sunrise, midday, sunset and night settings.
What fits a 20 inch tank?
The Fluval Plant 3.0 lists 15 to 24 inches. The 15 inch submersible strip also fits inside a tank of that length according to its size.
Can I run these lights from a USB port?
The AREPK lamps list 5 volts and a 50 inch USB cord. For the others the listings give other voltages, so check the power supply on the product page.
Do these lights make plants grow?
The listings say full spectrum light helps plants grow, and the white and blue strips say their light is sufficient for underwater plants. The listings do not give plant-specific results.
Bottom line
Match the light to the tank length and decide whether you want it above or inside the water. If you came for a plant tray, check the dimensions on a tray listing before you buy, because none of these eight is one.
