OK, next mad project... convert the AeroGarden into a proper aeroponic unit...
This is how I want to build it. I have no idea if this will work, leak, flood my house or grow stunning plants quicker than hydro...
1. Sicce Nova (flow adjustable) water pump, 250-800 lph (66-211 gph), 13mm diameter water outlet pipe.
Edit: this pump was found to heat the water up too much, trying another one! (Sicce Mi Mouse, 30 to 300 lph (7.9 to 79 gph) ).
Edit2: this pump works a treat, it does not heat the water up and the spray is much more gentler - sorted!
2. Rigid plastic pipe, 13mm diameter.
3. Various 'T' pieces and pipe end caps, 13mm diameter.
4. Air pump (for water bubbler), already have this from before, it's a Rena 400 model. I will attach a cylindrical air stone to this.
5. Two types of sprayer to see what works best - the green one has 360 degree spray pattern and a small spinner, the brown one has two 180 degree fixed spray outputs.
1. Remove the AG water pump and central column from the AeroGarden to free up the space, the column is only held on by one screw.
2. Cut two sections of rigid plastic pipe, each 5½ inches long, I used a very sharp knife for a clean cut.
3. Measure and cut another section of pipe to go onto the water pump. This measurement will vary depending on your model of pump, you want the sprayers to be just below the top of the AG lid once it's clicked into place.
4. Assemble all the pieces, pipe, 'T' piece and ends as per diagram below.
5. Drill 4 holes in the pipe and screw in the 4 sprayers, 2 in each side and equally spaced.
6. Mount the whole assembly in the AeroGarden, put on the lid and check the bar runs centrally in between both sets of pods.
7. Check the operation of the device, I have fitted an optional cylindrical airstone at the front to provide an injection of extra oxygen to the water. Once it's all going, then the task of checking for leaks begins... It will leak from the back, because of the hole left by the AG pump and also from the front lid - both solved by using some duct tape to seal the problem off. I have not tried different ways of doing this yet, work in progress...
Due to the aeroponics system, the possibility of the sprayers getting blocked is increased. I would recommend you put the water pump in a fine micron mesh bag (which you can buy in aquatic shops) that can filter any debris from the plants, wayward roots etc. Failing that, you can use some panty hose which acts as a good filter.
