Alaska Grow Bucket Update

Here is the latest update on my Alaska Grow Bucket System. All of this year's tomato plants seem to be doing as well as ever just 4 weeks after transplanting into the improved Alaska Grow Bucket System. 


My new fertilizer seems to be promoting blooming over foliage growth. At least I am not getting the large bushy plants I had last year. This year I am trying Jobes Organics Vegetable & Tomato fertilizer this is listed as a 2-7-4 plant food made from bone meal, chicken feather meal, and composted chicken manure with additional beneficial  bacteria  and fungi including mycorrhizae. I also cut back on the total number of plants to allow more space and hopefully improved ventilation and humidity control. I have also tried to be more vigilant in pinching off unwanted sucker growth.


All of the Grow Buckets are connected by a single gravity feed 1/2" flexible vinyl tube that is fed by a float valve regulator in the green bucket with the orange lid in the upper right corner of this photo. This maintains a constant self-watering irrigation system that requires no electricity.


The Float Valve Regulator in the green bucket is connected to a 35 gallon gravity feed reservoir made from an inexpensive plastic trash container. At this point in the season I simply refill the bulk reservoir about every 2 weeks. As the plants continue to grow the water needs will increase and the refilling frequency will also increase. The beauty of this system is that the peat based growing medium will absorb the correct amount of water to remain moist. So the system is self regulating - as long as the water supply does not run dry. A simple visual check every few days is all that it takes. Another advantage of any Sub Irrigated Planter (SIP) system, for those gardeners that live in arid climates with limited water resources, is that by covering the Grow Buckets and keeping the reservoir covered you will greatly reduce water loss through evaporation.  This is another problem that occurs with traditional planting methods and above ground irrigation. Water savings can be substantial.


Here is an overview of the entire improved Alaska Grow Bucket - Sub Irrigated Planter (SIP) System. From The Bulk Reservoir, to the Float Valve Regulator, to the easy to make Alaska Grow Buckets. It works great for tomatoes, but works equally well for peppers, eggplant, cucumbers, and many other vegetables. I believe it is the easiest system that anybody can use to grow their own food at home - on a terrace or balcony, a porch or patio, or in a backyard greenhouse. Get your Free DIY plans HERE.


And that's what it's all about.

  1. Looks like a good system. I think I'll try it.
    Thanks for the information.

  2. Interesting setup, and I have an idea you may want to consider - after reading through some of your entries, you mention the problem with the temps dropping at night. This is a common problem with greenhouses, and it has to do with thermal mass. A common trick to increase thermal mass is to use water drums, painted black to absorb heat, and line the back wall of the green house. During the day they'll absorb heat, and at night they'll radiate it. This is because Water has 4 times the specific heat capacity of Air. Seeing as how you've already started black garbage cans, adding more, even a second line on a rack above the first(connected to the bottom layer via a float valve), will greatly reduce huge temp swings.

  3. How do you prevent water stagnation issues that occur with the water in the barrel for multiple days/weeks/

    1. I haven't had any problems with water stagnation.

    2. Add a small amount of microbial tea.

  4. Put an airstone in it from an aquarium.

    1. I don't used an air stone - I am trying to avoid electric power for pumps or fans. I have one solar powered greenhouse fan for ventilation.

  5. So this is a hydroponic system then, correct?

    1. No it is not a true Hydroponic system - it uses a peat based growing mix.

  6. Very cool idea, wondering what the role the colander plays?

  7. I'm not sure if I missed something, but I would like to know the soil you used and then if that's plastic on top? Does it get moldy?

  8. What an interesting set up .. .I have some items growing in containers ... I may to try this in the near future

  9. This looks very interesting, have you tried it with any other hot weather crops? I am thinking peppers or melons?

  10. This also looks like the earthbox system that I have been using for about 10 years. It works great!!!

  11. I'd love to see the inner workings of your green bucket.

  13. Look up urine as tomato fertilizer, sounds like just the thing for your purpose.

  14. would you share the information regarding the solar unit you are using for the greenhouse? thanks

  15. Hi Jim,

    This is great info, this has helped me resolve the challenge I have with keeping my plants watered, while away on business trips of 3 days and longer.

    As per Anonymous post 10June - Urine is an amazing fertilizer. One can search for "pee ponics" with your fav search engine. You will be amazed at how well your plants grow :-))

    Thanks for sharing.

  16. I love this! It really seems like a great idea and easy system to follow. I am wondering if it could be hooked to aquaponics as well - maybe a holding tank for the dirty water if it couldn't be sent directly around the system?

  17. could I use a burlap or muslin sack instead of the fabric shopping bag? the sources for some of those bags are shady and many test high positive for lead and other toxic substances.

  18. Are that holes in the buckets?

  19. Great post. I'm a new follower. My name is Laurrie and I write the Baked Lava blog at www.bakedlava.com. I am an avid container gardener and a full-time RVer who lives in SW Washington state. I'll be following your blog with great interest as I'm amassing heirloom tomatoes to grow from seed this summer. I have 33 varieties so far with more on the way. My set up is a bit different, I don't do the self water thing, but this is one of the coolest tomato growing gigs that I've ever seen. I am mostly a food blogger, but I also post about my garden. Great blog and I'm glad I found you!

  20. What about digging a walipinni green house dug into the ground except the roof you would stay warmer when the cooler weather starts to move in. Unless your sitting on rocks then that wouldn't work.

  21. Thinking out loud here... I suppose one could use plastic tubs as well.. thereby increasing the flat growing space for lettuces and other root vegetables. Food grade plastic buckets are cheap or free for the asking at bakeries, restaurants, etc.Also, I totally advocate a previous post about using a thermal water bank of garbage cans / black painted metal drums to help keep temps more stable in your greenhouse. The advantage of drums is that you can stack them Or use the plastic barrels that ilives,etc come in.Adding a stone floor or a brick floor that can absorb the heat also helps.

  22. I am curious as to the purpose of the colander as well.. Can you please explain. I did read the pdf but no mention of its use.

    1. The colander holds the bag off of the bottom of the bucket and allows the water to flow freely - otherwise the flow becomes blocked. I have seen some people use rocks - but the colander works best for me - I suggest that you experiment and send me your results.
