Replaced all the traditional growbed from my CRAFTS set it took me two days to do and what a long day today.

Started by removing all the old growbed from the set.

Gutter tested for leak, only one leak due my mistake for not noticing the slight damage part on the gutter.

Gutter placed at an incline, reducing water and make it easier to do a leak test.

I use the standard Solvent Cement for PVC and it does work really well. Use a fresh bottle and apply generously, it will seal good. As stated one leak but easily fix with a hot glue.

Once the old growbed out, a new racking needed for the gutters. Gutters are 13 ft each (4 mtr) the Dikson bars or angle iron is 10 ft long. Ill put additional length on both ends to support the extra gutter.

Using these angle iron is easy to custom make the needed rack, took me close to four hour to make it.

The rack need to be level to ensure water do not spill out from one end before the siphon operates.

Those white tubes is needed to ensure pots didnt topple and for root to hold on to something. The tubes is the electrical conduit which I often use as plants support.

Siphon use is the 15 mm mini, I need to see how it perform. On some installation siphon need to be tuned, usually the outlet pipes adjusted to make it works better.

Inflow is from one pump rated 2000 liter per hour flow at 30 watt. The power requirement for 15 mm siphon is very much less, about 1/3 of that 25 mm siphon.

Water from the pump is divided by four since there are four gutters, each with its own siphon. Easiest way to divide and distribute water in Aquaponics is by splitting it by two and four. It will divide evenly and most of the time we dont need any tap or valve to adjust.

Siphon outlet is best to be as far away from the inlet, a pair of gutter emptied into one of the left return tank while the other into the right tank. Water feed taken from the feeded tank with a single pump as stated above.

Took the above photo at 21:30 hrs, the set completed at 19:00 hrs. Need more pots.

This #guttergrowbed is mainly for small plants and leafy vegetable. It is not recommended for large plants. I will further my Aquaponics trial using this method and hopefully it can evolve into something cost effective to operate commercially.

diy countertop aquaponics | Green Wall from plastic recycled bottles

diy countertop aquaponics

My Project was to create a Green wall / living wall using recycled plastic water bottles, I wanted to use as many waste product parts as possible.

                                        

I started with drilling a 1" hole in bottom of bottles and 2 x 2 1/4 " holes in sides, then joined them together end to end.

I realized that the only way water would travel all way threw would flood the bottle to half way making it to wet to grow so used a plastic drip pie cut in lengths and L corner joints to complete the loop, I then made lots of drip holes in each growing area for water to leak threw.

I built a wooden frame to fit snug to the size of bottles and brackets on back to support them ( This was a mistake, next time ill use something like peg board to give more support)

I used zip ties to attach each neck of bottle to back support straps

I sprayed  everything Matt black to make it look nice.

sprayed back too

then i filled with a light peat mix and vermiculite growing compound ( the weight made all the bottles sag a great deal)

finely added as many green house plants ferns etc as i could get, I really didnt get enough to make it fully covered but it still looked cool!

I them drilled small hole in top and added a tube to top pipe for watering, the last bottle was left uncut as a collection chamber, i originally intended to attach a solar water pump to the collection chamber to re-pump to top again but never completed it!

This is the Green wall several months latter!

The main problem was watering! the water would pass threw the pipe too quickly and not allow enough to soak threw drip holes, My next one I will cure this by adding a piece of sponge in the tube at every joint to slow the water transfer process down, You can also see the support wasnt adequate and the weight crushed it all down. The angle of the bottles holes should have been more upright too!
