Tower Garden Review


I recently lost all of my phone numbers and was forced to respond to every single message with “Hey, sorry, who’s this?”

Needless to say, it was getting a little repetitive…but that changed when I got a picture message of two Tower Gardens with the message, “You want these?”


Turns out it was one of my good friends who works with a company that gets a lot of free product for promotions. They didn’t end up using the Tower Gardens and wanted to get them out of the office, so my buddy thought of me, which was very cool of him.

I stopped what I was doing and drove downtown to pick them up. In about an hour’s time, I had two fully assembled Tower Gardens set up in my backyard and ready to grow!

The Ultimate Tower Garden Review

This post is going to be an ever-updating review of the Tower Garden product as I go through a full grow cycle on both of my gardens.

To start off, here’s a quick video tour of what the systems look like.

Planting Seeds In The Tower Garden

I sprouted a bunch of seeds (kale, a few types of lettuce, spinach, chard, and beans) and gave them a week or so to germinate. They started to pop up like crazy and I knew the time had come.

It was finally time to plant in my Tower Garden!

I filmed a quick clip to share my thoughts on the planting process and the three things you really need to watch out for if you want to plant your Tower Garden correctly. Check it out:

Transplanting Into The Tower Garden: My Mistakes

There were a few things that I messed up along the way of transplanting into the tower.

  • Make sure to harden off your seedlings enough before transplanting
  • Don’t let your seedlings stretch too far before you transplant

This video goes into more detail about the transplant process and what I could have done better. Don’t repeat my mistakes!

The Growth Explosion!

After adding a very small amount of nutrients to the reservoir and pHing the solution, I let the garden grow for about a week or so. I wanted to be sure that the plants weren’t suffering any wind/temperature/sun shock from transplanting, as well as let them mature a bit before I upped the nutrient solution.

After a week, I added another 450ppm of General Hydroponics Three Part to my solution, bringing it to around 850ppm. Around 350 of that is due to extremely hard water in San Diego, and the remaining 500ppm was GH 3 part. I also readjusted the pH, as it had rised from 6.0 to 7.0 over the course of the week. Finally, I added some Zyme Alive! (review coming soon) from my buddy Max at CropKing. Zyme Alive! is an additive that speeds up biocatalysis. In other words, it helps your plants absorb nutrients faster and deploy them in critical growth functions.

The results of these changes were…explosive. The video below goes into more detail, so check it out:

Growth After One Month In The Towers

Finally, it’s been a month! Check out the new updates in the video below. For those of you who want to watch, you’re missing out…because the plants absolutely blew up in the last week…check it out:​

The First Harvest Off Of The Tower Gardens

I was able to harvest the greens pictured above only 3.5 weeks from placing seedlings in the tower. There are a lot of different types of greens going on in this picture, all of them a mix of spinach, lettuce, kale, or chard.

By the way, have you looked at those spinach leaves? I’ve never seen spinach leaves that big before! I’m not going to say it’s all the Tower Garden’s doing, because I carefully watched the nutrition and pH levels, as well as added some Zyme Alive biocatalyst into the reservoir.

Regardless, it’s clear that the tower garden can produce massive amounts of greens in a short amount of time.

The cucumber and beans are still in vegetative phase, and as I harvest the greens I’ll be transitioning them into the flowering phase in the next couple of weeks.

  1. With all due respect; have you considered that there is no biodiversity in your growing medium as there would be in soil? Personally, I avoid growing with chemical nutrients and prefer using the “Garden Tower” (subtle name difference) system that composts your kitchen scraps inside the unit from which your plants can gain natural nutrients. Also no water is lost as there is a reservoir at the base of the unit which can be used to water the plants again. As for growing year round; it would depend on which part of the world you live in. The unit could be placed in a small greenhouse to extend the season is cold parts of the country, but perhaps not used in the frigid months of Jan/Feb/Mar.

    • Yes, this is a downside of the Tower Garden system (or any hydroponic system). It’s a trade-off between space / efficiency and biodiversity / organic approach.

  2. Which media should I use to plant the seeds and then transplant them to the tower garden. I recently read your article regarding the rock wool, which is the media provided by the company. I would like to use a better alternative. Thank you.

  3. I am very enthusiastic concerning hydro and aeroponics, however, after spending many hours searching the web I cannot get answers to very important questions, such as:
    The majority of systems seem to concentrate on salad plants but there is almost no serious information about: tomatoes, peppers and cucumbers.
    The point is that I would like to feed my family with all their fruit and vegetable needs throughout the year. It has been claimed to be possible but I have yet to see a system in operation that demonstrates that possibility.
    Tower is the most attractive option but, what about huge roots developing and finally blocking even the water supply?
    My system would be inside the house and there would be lighting etc as required but I do not want to invest and then find that I can only, successfully grow lettuce!
    Kindly offer your experiences and knowledge.
    Thank you,

  4. Is there a media that you would recommend that can be used for planting seeds and then transporting into the tower garden? My tower came with rock wool, but I recently read your article about that and would like to see what you would suggest. I don’t know if it makes much of a difference, but I will be doing a lot of growing indoors using grow lights as I live in Canada. Thanks!

  5. Have you used it all year long, or just throughout the growing season? What plants did the best? Also if you didn’t get yours for free, would you buy the system or do something else?

    • 1. I live in San Diego so the growing season is quite long here
      2. Leafy greens did amazing, but I also grew squash in this system
      3. Yes, it’s one of the best vertical gardening products out there for home gardeners in my opinion.

      Hope that helps!

  6. Kevin;

    Thanks for getting back.

    I have used Botanicare nutrients and find they don’t work as well as tower tonic. I am not trying to push any brands but trying too many companies can leave you bankrupt; this stuff gets expensive. I was advised against GH because it is made ( or so I am told ) with petroleum. With the GH you use, do you use 1 mix for vegetative growth and another mix for blooming?

    Also, may I ask where you use your tower gardens? It looks like somewhere south; Florida maybe.

    I appreciate the info;

    • Hey JC,

      San Diego, CA. Close in climate to Florida so good guess!

      I use a blended mix as the plants go through their growth cycle…you can actually find a recommended growing mixture on the back of the bottles, but you always want to look up the schedule for the exact plants you’re growing 🙂

  7. Kevin;
    What nutrients and how much per gallon are you using on the tower garden? I have a tower garden and have grown all kinds of things. However, they grow best with the tower tonic which is recommended but it is very expensive. I have tried other brands but haven’t had the same success.
    I am here in New England and we don’t have a very long growing season nor the best weather.

    • Hey JC,

      I use General Hydroponics 3 Part (find here: I don’t use the tower tonic and don’t necessarily agree that things grow best with it – you should definitely experiment! Give either GH a shot or some other nutrient company and research the best blends for the exact plants you’re growing and I’m sure you’ll have better results!

      • Kevin;

        Another question I forgot to ask is what is your TDS and PH levels and do you vary them depending on the growth stage?

        Thanks again;


        • I try to keep pH around 5.8-6.2, see my article for more information on that. As far as nutrient TDS, you can usually give them more as they get larger and move towards their flowering phase.

          • Kevin;

            Are there any sites where used garden items are sold? I am looking for another tower garden but don’t want to pay $600. I’m hoping to find one used.


  8. Hi Kevin! Can you potentially post the videos again or in a different setting? They are not coming up on my web page here. I’d love to watch! Thanks

    • What are you using, desktop / mobile / tablet and what browser? They work for me right now but I would love to know what’s going on. You can also subscribe to my YouTube channel and look for the Tower Garden playlist 🙂

  9. Hi Kevin, thank you for the videos. I wish you would date them so I know about when to expect another. I am hoping someone will come along that no longer wants their tower & I can get 2 for my home. this looks like something I can do since I can no longer plant a garden in my yard.
    thank you again for sharing!

    • Hi Anastasia. I am a distributor of Tower Gardens and would love to hook you up with some towers of your own. is the site I have for ordering.

      Lookin at the progress of what Kevin made with his towers has me excited to see what my family will get from our 3 towers we just started. I have one tower already growing plants and we want to set up one just for strawberries (we love them a lot and make a lot of deserts from them). Thanks for posting the videos. I will be sharing the vids with my friends.

    I have had my tower garden since April. I am amazed at the growth and quality of my plants. I have harvested many cucumbers, zucchini, Bok choy is gigantic. Tomatoes are in abundance. peppers are huge plenty of lettuce (all types). I do like to use Parthenocarpic: Plants (are able to set fruit without pollination.) cucumbers, zucchini, eggplant. Johnny’s seeds from Albion Maine is a great source od seeds. I would recommend this garden to all. You will eat healthier and save money in the long run. I use the nutrients recommended by It is also a great hobby for my wife and I to work on.
    Good luck

  11. From a “Prepper” or “Off the Grid” point of view: Do you see any reason why this design cannot be modified for Aquaponics…? Fish produce different nutrients…

    • Hi Roy,

      I definitely think this could be modified for Aquaponics – but this is a commercial product, so it might be more beneficial to design your own aquaponics setup. It’s a unique idea though, the vertical plants + water base.

  12. Hi. I am new to the tower garden. I bought he system and actually shipped it to Kuwait where I live due to my employment. I planted spinach, tomatillos, tomatoes, kale, three different types of lettuce and broccoli, plus some herbs. Everything germinated except the spinach. It has been about a week and nothing. Do you know how long does it usually take for it germinate? I planted two sets of seeds and no activity in neither one.

    • Hey Yari,

      Thanks for the comment. Spinach sometimes takes a LOT longer than other plants and I’m not sure why…sometimes it pops up in a few days, and sometimes it takes a week+. You may want to consider pre soaking the spinach seeds in water to get them started a bit quicker. Hope that helps and thanks again!

  13. Our tower garden has 3 plants. All others died before being transplanted. They came up and simply stagnated. Roots did not stick out so when you transplant they die. If you wait, they die. A waste of good money spent on this item.

    • Hmm…sounds like an issue with the transplant process and not the Tower…are you sure that they were getting enough water from the system after the transplant? I had an issue with that where a few plants died because the roots just dried out and the plant died. Hope that helps!

  14. To answer your question about nutrients, tower gardens come with tower tonic when you order them. It’s a variety of earth minerals that can support any plant combination, you just can’t grow root veg, trees, or bushes in a tower because of the design. It’s wonderful stuff! We are currently growing Swiss chard, a variety of lettuces, herbs, eggplant, tomatoes, cukes, zukes, squash, green beans, sugar snaps, celery, kale, etc. We LOVE our tower! The only challenge is abundance and the occasional pest.

  15. My daughter today texted me 14 photos of her Tower Garden and I was astonished at her project and how gorgeous everything looked. We spoke as she explained it to me and showed pictures of salad greens and asparagus in bowls ready to eat from this amazing devise. She loves that she doesn’t have to deal with soil, and it is organic, healthy and stunning to see. I’m extremely impressed with her and that everyone is eating healthy, fresh foods.

    • Hi Devon,

      I am impressed too! Your daughter sounds like an awesome garden already! I’d love to see the pictures as well… My gardens are going to take some time to get to her level 🙂

      The real question is…are YOU growing anything?!

  16. Hello, I am seriously considering purchasing a Tower Garden (I am not lucky enough like you to get it free). A friend of mine is a rep for Juice Plus and she has one she is raving about. From what you said it sounded like you were going to be growing most of the stuff I would like to grow…plus a tomato plant and probably serrano. Have you had any of your seeds germinate (not sure if that is the term I am not really much of a gardener)? Thanks for any information or tips. Leesa

    • Hi Leesa,

      They look like they’re going to produce a huge volume of plants, but my seedlings actually died. I left them a little bit too long and I need to replant them. I’m going to be filming some new videos soon and I will definitely keep you in the loop. If you haven’t already signed up for the newsletter, I’ll probably be releasing some extra info on there, so be sure to sign up! Thanks for reading, hope to see you again soon!


    • Love my Tower Garden. I am currently growing lots of small tomato varieties, cucumbers, lettuce, swiss chard, spinach, chives, and snap peas. It’s a lot of fun especially if you have a limited space. We only have a balcony for our condo, but it works great with a Tower Garden. It’s really easy to grow seedlings in rock wool and transplant them into the net pots. If something doesn’t take off, just pop it out and plant something new. Super easy to take care of. I just check the water twice a week and add as needed. I add tonic about once a week, sometimes twice depending on how much water has been used. Tomatoes made the water acidic so now I correct the PH weekly. The kit has everything you need.

      • Margaret,
        Would love to see some pictures soon! It sounds like you are very far along. How did you manage growing tomatoes and non flowering plants in the same time for a garden nutrient wise?
