What I like
1. Affordable and allows you to quickly germinate seeds especially tomatoes , parsley ( where seeds are very very small) etc
2. Germinates well

What I do not like
1. No matter how careful you are filling in the water, there is a pretty good probability that water can spill over, and the electrodes can corrode and can cause the unit to misbehave- flickering lights or malfunction.

Good news is that it is easy to replace and within the warranty period you will get a super-fast and very prompt response from customer service. You will have to send pictures of damaged part which is a pain .. but will be taken care of

2. The replacement inserts are slightly expensive in my opinion

What you see in the second picture is a transplanted tomato plant into a pot and you can see it flourishing

Tip: don't wait too long to transplant else getting roots out of plastic holder can remove the roots easily

This is really great!! Grows herbs and lettuce so well. This picture is after 2 lettuce harvesting too! Easy to use and care for. Very happy with this!

Seriously?!? Can it get any simpler than the iDOO 12 pod indoor hydroponic herb garden?!? I had the whole thing up, planted and running in maybe an hour...

My arugula sprouted in 1½ days and I woke up this morning (day 3) and the four different basils are just beginning to sprout. So...

I just ordered my second iDOO from Amazon. Excellent product. Insanely easy. Very cool (literally and figuratively) using only a 23W LED panel. I highly recommend this hydroponic garden!

Update 4/7/21: It's been 6 weeks since I began my adventures in hydroponics with the iDOO 12 pod indoor... and I've been extremely pleased with the results and I added two current pictures. I began by planting all 24 pods (I have 2 units) - the blank spots in the pictures are plants I've already transplanted. All of those transplants were successful but for one. I had Thai basil next to lemon basil. They had both grown so fast and so bushy that I had to transplant them; however, their respective root balls had grown so incredibly tangled that I was unable to tease them apart (at least without likely causing serious damage.) I finally decided to pick a spot midway between then and used scissors to cut straight across. End result- lemon basil thriving but the Thai basil is lingering on life support (that, in and of itself, is a good sign since today is day 3.)

Additional thought: an earlier reviewer mentioned how fast basil sucks up the water. My experience is the same. I started with sweet, Thai, lemon, purple and cinnamon basil varieties and I was having to add 1 liter (between 2 units) every other day. The burn rate I experienced was just over 5 weeks to use all of the part A & B nutrients supplied in the kit so for a single unit, figure about 11 weeks. I've started the second unit's nutrients as of this posting. I've looked all over Amazon for more iDOO parts A & B nutrients and all I can find is a kit with the nutrient + sponges + baskets + covers (the latter two being non-consumables, so kind of an underhanded way to inflate the price if you ask me.) I'm intending on buying an "off-brand" variety of hydroponic nutrients from the many offered on Amazon and I'll update with my results. I figure if iDOO doesn't want to make $ selling individual consumables (if I'm not changing out a plant, I don't even need additional sponges but a plant's gotta eat, right?) then I'll go with an alternate source. (iDOO, you listening?)

Other than non-support wrt the nutrient solutions ( I expect this will be of little consequence due to all the alternate sources on Amazon) I still rate this product 5 stars. The project has been fun and I'm amazed at how quickly some plants grew on a day-by-day basis! I've had no problems with the lights or pump on either unit. The timers have both been creeping forward (~20 minutes in 6 weeks being the worse between them.)

It's been fun, basically automated with minimal user support-what's not to love?

After all that, I forgot to add the biggest plus-an absolutely incredible constant variety of fresh herbs. I'll never go back to dried herbs because I've discovered that fresh tastes so much better! One word of caution: don't eat an entire sage leaf-WOW a little goes a long way. I like sampling all the basil varieties by eating a leaf off the plant to contrast and compare against each other so I thought I'd try that with the sage. I won't do that again.

I set this up on Sept 13th, the pictures attached are from Oct 8th.
I bought the seeds from a seller on Amazon, these plants are thriving in this hydroponic set up for sure!
I'm growing Cilantro, Lavender, Tiny tims, Parsley and Mint. The tiny tims are flowering! The Mint and Lavender seeds sprouted late, I think it's the genes and not the set up. The rest of the plants grew beautifully.

I would suggest to plant these with space, I didn't do a good job growing so many things and planting them close to each other.
I'll have to space them out and prune them so they can thrive.
It's a good setup for beginners, I recommend this 9/10.
I docked one point because the fan isn't that affective, it's mild and I don't think it does a good job at proving sufficient air flow. I have a ceiling fan that does the job, but relying solely on this fan will not suffice.

The hydrogen arrived in one day. Setting it up was quick and most of the instructions clear. The only confusion was related to the nutrients. The instructions for the preparation of the nutrients was on the jars not on the paper. There the directions were to add a set amount to the water.

It's one week since we planted and the seedlings are already showing.
