I dont see a thread about air stones. Will be starting some 5gal bucket DWC soon and was wondering what you guys are using?
You running 5gal buckets? What size disk? 4" Will these work well or are they not good? http://www.ebay.com/itm/6-pcs-Air-Bubble-Disk-Stone-Aerator-Aquarium-Pond-Pump-Hydroponics-4-/301372440733?pt=LH_DefaultDomain_0&hash=item462b32809d
Well theyre 4gal and yeah those will work but you can get them cheaper on amazon. Yes theyre 4",i use 2 per rez 😊
You are either going to have to get something big enough to weigh itself down (which will cost you around 200 for 24), or do it rumpleforskin style and weight down the little cheap guys with pvc. Sent from my iPad using Grasscity Forum
Thinking of running a 70lpm pump per 6 buckets. Would these http://www.ebay.com/itm/6-pcs-Air-Bubble-Disk-Stone-Aerator-Aquarium-Pond-Pump-Hydroponics-4-/301372440733?pt=LH_DefaultDomain_0&hash=item462b32809d not be good enough? Or would I need 2 per bucket?
I run 5lpm per gallon. I run three 5gal buckets at 110lpm. Only need 75. I would say get a little bigger pump. Two would probably cost more than a little bigger one.
I use these. 2" stone balls. They cost £1 each and are good for about 5 litres per minute each. I got tons of them
The rough estimation for pump size that ive heard is at least 1 watt of power per gallon of water. A couple of these would probably do the trick. http://www.ebay.com/itm/Elemental-O2-Commercial-Air-Pump-951-gph-Aquaponics-Aquarium-Hydroponics-Pond-/141113435413?pt=US_Hydroponics&hash=item20db042515
Why not go with a water fall effect into the top of each bucket this way no air stone needed an no bacteria can attach to the stones
Yeah that one is 60lpm I was going to be using 1 70lpm to 6 buckets. There's 3.78 litters per gallon. And I would assume that if I filled the water to the bottom of the net pot in a 5 gal bucket than there would be about 4 gallons in each. 24 gal or almost 91 litters. I read some where that you should have at least 1 lpm of air for every 2 litter of fluid. I think I would be around 1.7ish lpm air. or 70lpm air to 91 litter fluid.
You still need an air pump. Pushing air through the water isn't just about slowing anaerobic bacteria, it's about providing the roots with oxygen. And they use loads of it
If you have 4 US gallons per bucket and 6 buckets (24 US gallons) that's about 90 litres. I would recommend about 45 litres of air per minute. (7.5lpm per bucket). But more isn't going to be a bad thing
yeh i use a 6" flat/round airstone plus the blue golf ball size stone & when my plants really get going & roots are filling the 20ltr buckets up then i pull the 2" golf-ball stone up the side of the pots around a 1/4 of the size of the pot up , therefore helping maintain they lovely air-bubbles find every possible root intake i can find. I used to just have 2 4" flat/round on the bottom of pots all way through then the next grow i experimented with 5 of my 10 plants using 5 with 2 4" on bottom & 5 with 6" airstone on bottom & 1 2" golf-ball stone a 1/4 of the way up (when roots well developed) & all 5 using golfball stones produced nearly an oz per plant more than 1,s using 2 6" stones on the bottom , not that the 1,s with 5 6" stones were a poor yield , oh christ no , but sometimes experiments work & thankfully i was due a bit of good luck Never looked back , still doing it , keep both on bottom till roots develope then pull up golfball. DO NOT PULL UP BOTH AS YOUR WATER LEVELS MAY DROP BELOW STONES & ROOTS LYING IN STAGNANT WATER AINT GOOD Happy growing peace
