iDOO Hydroponics Growing System Review

I decided to write an iDoo Hydroponics Growing System Review for you and share my experiences. I’ll continue to update this post as time goes on as well as additional content about each type of plant that I grow. I’ve been having a lot of fun with it, and I recently added a second unit.

I hope you find this review helpful. I earn from qualifying purchases at no cost to you. If you find this review helpful, you can purchase your hydroponic garden using any of the links in this post. You can view my go-to hydroponic growing sponges, machine, and other items in my Amazon Storefront.

iDoo Indoor LED Hydroponic System

I ultimately purchased the Amazon iDOO hydroponic growing system called “iDOO 12Pods Hydroponics Growing System, Indoor Herb Garden with Grow Light, Plants Germination Kit Built-in Fan, Automatic Timer, Up to 11.3″ mainly due to the price, but I also liked the compact size. I wasn’t sure if this hobby would last for me so I figured I could upgrade to a different model later if I really got into it.

Even though I read that it’s almost impossible to grow 12 plants in a 12 plant system, I still chose it so I would have the option to start more plants from seed and then transplant them outside if I want. The iDOO hydroponic system is compact so why not have the option, right?

iDOO Hydroponic Indoor Garden System Set-Up – How To Use

The assembly was quite easy and the instructions are good. Everything snaps together with absolutely no tools necessary. It came with everything you need to get started with the exception of seeds.

Unpack the system and remove the white tray with holes and you’ll find everything inside. The pump is already installed and you don’t need to do anything with it. The power adaptor has a black piece of plastic on the end of the cord and it matches up with a black square in the light. The pump plugs into the light on the other side, closest to the pump.

The pole that holds the light snaps in. Just gently work it in until it hits the bottom with the wheel height adjustment facing the wall. The light snaps right in on top of that in the oval groove. Add 4 L of water. There’s a gauge on the front which makes this easy.

Make sure the little plastic plug in the back is secure. When you clean the system, you’ll hold it over the sink and pull that drain plug then replace it to refill. They send an extra one so look for it in one of the envelopes. Add the nutrients per the instructions.

Once the water and nutrients are added and the two cords are plugged into the light, you can plug the unit in. Follow manufacturer’s instructions. Put the white tray with holes on top of the unit.

Put a seed in the tiny hole in the top of the brown growing sponge and then put the sponge in the basket and place it in an empty hole in the white tray. Put a clear plastic lid over the top and leave that in place until you see green leaves sprout. Sprouting can happen in as little as 2 days but some seeds take longer. Save the clear plastic lids for the next planting.

iDOO Seed Pods – Do You Need Them?

Nope! I bought seeds and planted them and had success with everything I bought. If you’re searching for iDOO hydroponic growing seeds, they have them, but you don’t necessarily need to buy them. When I bought my first indoor garden system, I added an herb garden starter kit just to get me going.

If I had this to do over again, I would just purchase exactly what I wanted to grow. I didn’t have success with everything that came with the herb starter kit. I replanted some of the seeds and had success on the second try with the exception of cilantro. Maybe I just needed to wait longer. I’m not very patient.

The seeds I bought from the store are:

  • Red cherry tomatoes – 2 days to sprout
  • Orange cherry tomatoes – 2 days to sprout
  • Mixed lettuce seeds – 3 days to sprout
  • Sweet Banana Peppers – 4 days to sprout
  • Sweet Peppers – 4 days to sprout

Please stay tuned as I have lots of things growing but I want to see successful fruits or vegetables before I write more. My tomatoes after one month are about 7 – 8 inches tall but I haven’t gotten a tomato yet. I also think I’ll need to move these outdoors as they are getting so big. I’ll likely leave one inside just to see what happens. I might have to make a trellis of some sort.

Other Things You May Want To Order

Things you may want to purchase extra of are the iDoo growing sponges. I don’t buy the same brand. I haven’t had to replace the baskets yet. I’ve been able to reuse them. You’ll need a new sponge each time you plant something.

Cleaning the iDOO Hydroponic Growing System and Other Things You Should Know

The light and fan come on every 10 hours. You can turn the fan off if you want to. The light is bright. I start my system when I leave for work and then every few days I unplug it and do the same. I don’t like the light glowing at night while I’m sleeping. If the light gets off as far as the timing goes, then I just restart it.

If the system gets lower on water, it will make a trickling noise letting you know to add more water. Adding the water will make it run more quietly. Other than that, you can hear it a bit but it’s basically very quiet. You can put these in a laundry room or extra bedroom. They aren’t heavy even when full so it’s not hard to carry them to the sink to drain and wash.

I clean mine out about once every 7 – 10 days. I drain and wipe out the tank. I also spray the pump off real well and remove any debris that is stuck to it. Fill the base with clean water and 1/4 cup of bleach and allow it to run for about 5 minutes. I add the white baskets to sterilize them as well.

Dump the bleach and water solution and add fresh water and allow the unit to run again. Dump and add fresh water once again after the bleach is completely rinsed. Always unplug the unit when there is no water inside then plug it back in when it’s full.

Add the iDOO nutrients each time you clean.

I put two tall drinking glasses upside down on my counter and rest the tray with all of the plants still in their pods. I just put one glass under each edge and this keeps me from damaging the roots or having to remove the plants from the holes. This works great. Keep plants with shorter roots closest to the pump. If roots are getting very long, you can trim them with clean and sterilized scissors.

You’ll see aluminum foil over some of my plant bases. This protects the sponge from light and stops mold from growing on them. In most cases, I was able to let the seed sprout and then put foil around the stem.

I Bought A Second iDOO Indoor Countertop Garden

This hobby has gotten serious and you can now find more hydroponic articles at The Countertop Gardener. For the iDOO Hydroponic garden review, I’d have to give it 5 stars so far. I don’t have a reason to be unhappy with it but I’ll be sure to update this over time. I wish I’d bought a different brand for the second unit to have more comparison, but I wanted everything to match on my counter. I may be adding more units to the garden shed, so I’ll let you know.

In the second unit, I’m growing Dahlias, Zinnias, Poppies, Canterbury Bells and Hollyhocks. Most of these will be moved outdoors once they get large enough.

Are you hydroponic gardening? What’s been your favorite thing to grow? Do you have any other questions about the system that I didn’t cover today? I’m happy to answer! Just leave a question in the Comments section. I monitor for spam so it may take a day or so for the comment to show. Thanks for visiting.

Happy gardening,



  1. Thank you so very much for your input I’m interested in the idoo unit, but I’m now sure I will most definitely will buy the unit.
    I’ve been gardening for a long time, but this year the heat killed all my crops. I live in Texas and the ­čî× is unbearably Hot.
    So I will be trying to get everything growing inside my house.
    Thank you so much for making it easier to purchase this unit.

    1. I’m glad this post helped. The heat here has been brutal on my veggies this year as well. I’ve been using the units to start a lot of flowers. Enjoy!

      1. I wanted to know if that thing is deep enough for the roots.

        1. The roots grow pretty long and eventually need trimming. I’ve pulled out some plants and had roots that are at least 8 inches. When I clean the machine, I cut overgrown roots to a shorter length. That’s a great question. I’ll have to add more information to the post for future readers. Thank you!

  2. I also decided on an iDoo after looking at many. I’m so happy with it and ended up with a second. Then I speed a secondhand Aerogarden online and grabbed that. I have micro dwarf tomatoes and dwarf hot peppers in my units currently. I’m enjoying hydroponics so much I’m also doing the Kratky method with lettuce and herbs. I have plants growing all over my kitchen! I’ll definitely grow year round from now on.

    1. It’s been so fun. I’m already contemplating a third. I have plants everywhere, too! I started heirloom tomatoes and they just got moved outdoors since they get really big but I had a 16″ plant in just about a month’s time. They’re so fun and addicting. Thanks for stopping by!
