Backyard Aquaponics
A place to discuss aquaponics

Brian, what that root from cucumbers?

I had the same thing happen twice and it was both from cucumbers. A single root grew down the drain that then exploded into a HUGE mass.

We should have a aquaponics dreadlock competition. You are the currrent title holder Hawaiinewbie

Oh... I think it was a somewhat sad very old swiss chard.... Just one tiny root supports such a huge mass. Says something for the efficiency with which a root can transfer nutrients?!

Ok.... so heres the thing. Temps have dropped down to between 15 and 20 degrees so it time for the trout! So now I want to figure out stocking densities went on some of the numerous stocking densities threads to try to figure this out and i was like then I was then again . Some people said and others and now i am a bit and .

I have 4000 liters of gravel growbed, with a 4000 liter FT and soon to have a 200 liter bio filter with 75 percent cut up black pipe and 25% scrubbies. I have a 4000 liter sump so 8000 liters of water in the system. How much would you all stock. I am thinking 300 fish grown out to 500 grams give or take 20 kgs. Does that sound reasonable or am I being dumb. Last season I did 6 kgs of +-200gram big fingerlings which probably topped out at an average of 1kg a fish, about 30 fish in total so call it 30kg's. To be honest it was hard to even see them in the tank. I want to have lots of trout but don't want to end up with a whole bunch of dead trout

3kg grown out fish to 100litre filtration.

4000 / 100 = 40
40 x 3 = 120
120 x 500gram = 240 fingerlings

I'd go 200. Allows room for playing with catfish.

Wow, that's a crazy lot of roots there Brian... So is your connection working ok now?

Thanks vlc. Sounds good. Earthbound, I only got logged off once yesterday, but no pics where posted. I have now started copying to a notepad when I write a long post. Just in case...

possibly one of the greatest uses of emoticons i have seen on this forum haha

I reckon you should be okay with up to 200 fish. (160-200)

Just read this entire thread. You do beautiful work, Brian!

(Also, what Freo said about the best use of emoticons...)

Thanks swanberg for the complement and freoboy. I had great fun with the emoticons .

Picked up a new pump for the greenhouse system today. Rated at 1500 liters per hour at a 2 meter head. Should do the trick! Just need to fill the other two growbeds and get some plants going. Am in a bit of a dilemma now as I have the mozzie fish in the tank now and would like to put some Tilapia in there instead. I fear the tilapia will gobble up all the mozzie fish in no time as I am told they chow their own babies. I could dump the mozzie fish in the sump I guess.

Some more pics of the produce and the windbreak. That reed stuff is amazing. I am going to go right around the system with it. I just supplied a pipe with a dripper at each piece of cane planted and away it goes. From a few stalks to a 12 foot high windbreak in 4 months! That last pic is my idea for a cheap flood control for the growbeds. just a end cap on the pipe and drilled and then it can be half mooned for the desired flood speed.

I like the flood speed adjuster...might have to borrow that one!

your place is starting to look like tatooine, if i see a pic with a droid crossing ill flip out lol. great work, inspiring.

Hey brando. Thanks and yes funny you should say that. I have been inspired by this

and am itching to try something like this combined with an ap system into a sustainable food producing house. Perhaps with attached dome greenhouse
