What do you fill the tubes with?

This looks like something I actually could do in my apt in AK... if it weren't for the terrible furry climbing beasts (feline) I live with. I am glad for all the hydroponic ideas I have seen on your blog and others. They really do address the 'space challenged'. Now if I just had permission to do such things in my apt. or work.

Brilliant. i saw this picture yesterday and made three smaller scale prototypes of my own. 1 = herbs and spices 2 = tomatoes 3 = soil from my front yard, i put a cup of red dye in the top of this one and have been watering it as i do the others. i want to see how long it takes the red dye to move through the native soil? THoughts?

I know that when people are doing indoor containers, they usually go for a much lighter mix than the outdoors soil - unless yours is a very sandy soil. Apparently, it will otherwise pack down on the roots too much over time, and if a high clay content is present, will retain too much water in the small spaces of containers.
Also, are you going to be regularly 'feeding' your plants, Wesley Mack? You'll be flushing the nutrients just as quickly as you're flushing the red dye :)

i live in the desert now and my knowledge of agriculture is limited to a chia-pet and some mold i grew on forgotten leftovers in the fridge.

the soil is semi-sandy and i added some tiny gravel throughout the mixture to hold roots and moisture but not pack tight like clay.

The dye is just a control for my sand mixture to make sure that the water is going all the way down the tube. and for how much water i need to use to saturate the entire column. looks like based on the size of tubes and mixture of sand im working with now it takes about a gallon to get to the bottom poured from the top. i have a little less than a 1/4 gallon left as runoff.

i have five gallon buckets under the tubes to catch and reuse any runoff.

im totally shooting in the dark here and based what im doing largely off pictures and what iv read about hydro. this is my first attempt and i have a little over 15.00u.s. left from my original 50.oo project budget.

any suggestions?

long term goal is to work up a process in writing and then offer it to the local elementary schools as a possible science project......if i can get it to work well with under local (Phoenix AZ) land and weather conditions.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
