That's correct, i have a tee just up from the outlet, straight through feeds the beds and the other feeds the venturi. I've also directed the outlet toward the pump inlet to help keep the inlet clear of debri.
Matt Dawson I just drilled a hole in a threaded plug so that 1/2" irrigation tube fits through tight into the tee, then adjust how far it sticks in until you get good aeration.
Matt Dawson of course, the setup has been flawless, replaced the original pump thats all. It's been running continuously since I did these videos, with very little maintenance.
@@richoz27 how does the little bit of worm castings and manure feed the whole system? do you ever add more? Is the nutrition more dependent on the health of the bacterial colony absorbing carbon from the atmosphere? Do the bacteria live in the H20 or mostly in the worm casting set up. Im curious what the limitations are, e.g. what factors influenence the fertilitiy of the H20, whether the nutritional content is limited by inputs, H20 dilution, aeration, or whether there are no limits and it can be expanded. Im thinking of interconnecting IBC totes to make a larger, connected system but it my be unneccessary judging the productivty coming out of only 1/2 tote resivoir.
@@mobiusdesigns some good questions i cant answer. As there is very little nutrients in the medium, plant health is obviously reliant on fertilizer input. I also add sea weed liquid fertilizer and rock dust. Aeration is to encourage "good" bacteria growth. Ive wanted to test nutrient content of the water but i have no obvious deficiencies, it continues to produce a lot of veg.
Nice setup..I need to understand how you are using one pump for pumping water and supplying air via the venturi.Does the pump have two water outlets?

@@richoz27 Thanks you mean the air outlet has been directed to the pump inlet?How many watts is the pump?
@@henrynyabuto4892 the aerated water flows across the screened inlet on the pump to help keep it clean. 100w pump off eBay.
Love the venturi. What parts did you use ? Didnt get a good look at it

Cheers man. Looked like it worked a beauty. I see that was a few years ago you still into it ?
