www.thebackyardfarmer.org This weeks video I finished the construction of my aquaponics system. The entire project is cycling. The fish tank, two sump tanks, and twp grow beds are all working in sequence. I have planted only one plant at this time and it is doing great. I show the progress on the other seedlings. The siphons were both changed to bell siphons in the growbeds.
Just FYI, plants don’t use UV light. Chlorophylls absorb light around 660nm (deep red, almost infrared) and 450nm (bright blue, almost UV) most effectively. Depending on what exactly you’re growing a little orange around 615nm helps too for carotenoids, I believe that’s tomatoes and carrots for example. Just incase you wanted to set that up. 🙂 happy planting

Nice job. I was wondering if your gravel will be porous enough to house enough beneficial bacteria to break down the ammonia. I know hydroton is porous but very expensive. I use 1/4″ lava rock. After cycling my systems, I have never had any ammonia spikes. Looking forward to your progress. Thank you. Check out my videos on fishandgreens channel.

if you are using rock or media for your garden make sure the water level stays below the top the media. If you are just using water with the roots hanging then make sure the whole reservoir is covered with plants or wood or plastic.

get a few pleco..they like to have somewhere to hide so id suggest building something at the bottom of the tank but they will eat up all the algae

use duck weed like he said it will keep algea down and feed the fish. take about 36 to 48 hours for one foot section of duck weed to become 2 feet so you will have to balance out the food intake of the fish with the growth of the duckweed. also to cut down on the algea you could cover the top of your holding tank with some vegtibles that also feeds the fish with the roots and the plants use the dirty fish water for fertilizer. good luck

Just a thought. The water supply to your grow beds might want to be located to the far end of the bed away from the bell siphon so that the nutrients have a chance to flow down the length of the beds before being evacuated by the siphon.

Call me cheap but whenever I buy green onions I plant the bottom inch or so in my garden. If it is winter I grow them out in a container of water. So I guess they will grow in a soilless system.

Well as you know I am just starting also. I have looked at a few places and only one seems reputable. The White Nile tilapia is probably where I go with. I saw that the Urban Farm Guys just started selling tilapia also, but is the quality there at first. I am sure they are gonna be good in the future, but right now I would go with White Nile. If anybody else has references please let us know.

Where, if you don’t mind me asking, are you getting your tilapia from? I’ve just started my system as well and have an algae problem due to my garden having exposure to the sun all day.

YES! you can definitely grow green onions in an aquaponics system. In fact, that is the only thing i grow in my mini aquaponics system, even though it might be so good.

You need more plants for the cycle. Where is water test kit? Good to see that you are at the cycling stage.
