AeroGarden’s shutdown left a weird hole in the countertop hydro market, and the past several months have been a scramble of Amazon brands trying to fill it. I bought four of them. Grew basil, cilantro, dill, and mint in each one, ran them side by side on my kitchen shelf for about ten weeks, and now I have opinions. Some of these units are good. One is going in a drawer.
Quick Answer: The iDOO 12-Pod is the best countertop hydroponic herb garden I’ve tested as an AeroGarden replacement. It has the best light, the most pod capacity, and a fan that actually matters for basil health. For tighter budgets, the no-name Herb Garden Kit with the ceramic pump is a surprisingly decent $40 option. Skip the GrowLED.
The Four Units I Tested
Quick rundown. I ran these from sometime in late December through early March:
- iDOO 12-Pod buy on Amazon , $80, 12 pods, 22W LED, built-in fan
- SUNCOZE 12-Pod check current price , $50, 12 pods, 24W dimmable LED
- Herb Garden Kit Indoor see on Amazon , $40, pod capacity varies by config, 24W LED, ceramic pump
- GrowLED Indoor Garden check price on Amazon , mid-range price, 16/24H timer
I planted the same herb mix in each. Same seeds (basil, cilantro, dill, mint from a bulk pack), same nutrient dose. Not a lab test, but close enough to see real differences.
Light: The Thing That Actually Decides If Your Basil Thrives
Basil is the test. It’s needy. If the light is weak or the spectrum is off, basil gets leggy and pale within three weeks and you end up with this sad, stretched-out thing that tastes like nothing.
The iDOO’s 22W panel with the two growing modes kept my basil compact and dark green, which is what I want. The SUNCOZE has a 24W dimmable light, and I liked the dimming feature a lot more than I expected to, because my partner cannot stand the grow-light glow after 9pm and being able to drop it to the lowest setting helped. But at full brightness, the SUNCOZE basil looked about as good as the iDOO basil. Hard to pick a meaningful winner on light quality between those two.
The Herb Garden Kit at $40 also runs 24W, and the basil did fine. Not great. Fine. A little leggier than the other two, and the light panel maxes out at 21 inches, which matters more than you’d think because basil gets tall fast and then you’re cramming it against the LEDs.
The GrowLED was the weakest performer on light and it showed. My basil was pale and reaching by week four. I don’t know the exact wattage because the listing is vague about it, and that vagueness turned out to be a red flag.
Pump Noise: Yes, It Matters at 6am
I keep my setup in the kitchen, maybe eight feet from where I make coffee. Pump noise is not a spec-sheet concern, it’s an every-morning concern.
The Herb Garden Kit specifically advertises a ceramic pump under 20 dB, and I’ll say this: it’s the quietest of the four. quiet. I forgot it was running more than once.
The iDOO is a little noisier. Not loud, but you can hear the pump cycle kick in if the kitchen is otherwise silent, and the fan adds a faint hum. I got used to it within a week. My partner claims she can still hear it. I think she’s making a point about counter space more than about decibels.
The SUNCOZE pump was middle of the road. The GrowLED had this intermittent buzzing that I found irritating, like a phone vibrating on a table, and it seemed to get worse over time rather than better. That alone would keep me from recommending it.
Pod Count, Height, and the Replacement Sponge Question
Both the iDOO and SUNCOZE offer 12 pods, which is plenty for a mixed herb setup. The iDOO’s 4.5L tank is larger than the SUNCOZE’s 4L tank, and in practice that meant I was refilling the iDOO less often during peak growth, maybe every ten days versus every week for the SUNCOZE.
The Herb Garden Kit has a 3L tank and fewer pod slots. It’s compact, which is a genuine advantage if you’re short on counter space, but you’re growing fewer herbs and refilling more often. Trade-off.
Here’s something that matters a lot now that AeroGarden pods are disappearing: all four of these units use generic sponge-and-basket setups. No proprietary pod nonsense. You can buy replacement sponges in bulk on Amazon for almost nothing. That was one of my biggest complaints about the AeroGarden ecosystem , and these alternatives all dodge it.
The SUNCOZE’s adjustable light pole goes from about 1.4 to 12.7 inches, which sounds like enough but felt a little short when my dill started bolting. The iDOO gives more headroom. For herbs that stay bushy (basil, mint), either is fine, but if you ever want to try something taller like dill or even cherry tomatoes , the iDOO handles it better.
The Verdict
Get the iDOO 12-Pod. It’s $80, which is more than the others, but the combination of light quality, fan, tank size, and grow arm height makes it the most complete unit here. I wrote about it beating out AeroGarden and Click & Grow before and my opinion hasn’t changed. It’s still the one I’d point a friend toward.
The surprise was the $40 Herb Garden Kit. I expected garbage at that price and got a functional, quiet little herb grower. It’s not going to win any contests for basil size, but for someone who just wants some fresh mint and cilantro on a windowsill without spending much, it does the job. I’d call it the honest budget pick.
The SUNCOZE is interesting but too new for me to fully trust. Only 24 reviews as of now. The dimmable light is a useful feature that none of the others offer, and if that matters to you (light-sensitive partner, open-plan apartment), it might be worth the gamble. But I’d want to see how it holds up over six months before I called it a winner.
The GrowLED I’d skip. Weak light, annoying pump buzz, vague specs. Nope.

Frequently Asked Questions
Can I use my old AeroGarden pods in these systems?
Not directly. The pod shape and basket size are different. But you can pop the sponge and seeds out of an AeroGarden pod and transplant them into the generic baskets these units use. I’ve done it with mixed results. Sometimes the roots adapt fine, sometimes they don’t. Honestly, just buy new seeds and generic sponges.
How loud are countertop hydroponic pumps?
It ranges a lot. The quietest I’ve tested is the Herb Garden Kit with its ceramic pump, which runs under 20 dB according to the listing and I believe it. The iDOO is slightly louder but still fine for a kitchen. Avoid anything where the listing doesn’t mention pump noise at all.
Do I need to buy special nutrients for these?
All four units came with starter nutrient packets or have nutrients included. After those run out, I use General Hydroponics Flora Series at quarter strength. I wrote about cheaper nutrient alternatives here . Don’t overpay for branded refills.
Is the iDOO really that much better than the budget options?
For herbs specifically, yes. The fan makes a real difference for basil because it strengthens stems and helps prevent mold, and the larger tank means less maintenance. If you’re only growing mint or cilantro and don’t want to spend $80, the Herb Garden Kit at $40 is fine. But for a full herb garden with basil as the star, the iDOO earns the price gap.
