DWC air pump question

[deconfrost]

I'm starting a new setup using DWC, 4 x 20L buckets, would 600L/H pump do the 4? it has 4 outlet so 150l/h each I'm guessing

thanks

I thought DWC only required air-stones, do you have a picture of the system will look like when setup? 150 GALLONS per hour is your pump-size, it will work fine if it is used just to circulate the water in your 5 GALLON buckets. You are asking about an air-pump or water pump with Venturi air-jet? Here is a link to a pic of typical DWC set up, all you need is a small air-pump, I would use a separate pump for each bucket because air-stones tend to clog and this would make uneven air distribution if you want to feed 4 buckets with one pump. I'd need more info to guess more than this, I'll keep an eye on your thread.

its 600l/h pump so its 120 gallon, I think I will use a 192L/H pump in each 20L buckets for now 2 plants in each, should be enough bubbles??

are we talking AIR pump or WATER pump? please convert your L/H to GPH (G/H) numbers, system used with the 420 member majority USA units of measure, this will help us both.no meters, no liters, no Cecius. I noticed you use some metric mixed our standard numbers for temp. Thanks no intent to offend crosspond growers!

ok its air pump, for bubbler bucket, I'm using 5" round air stone, its 38.4 G/H pump I picked out now for each 4gal bucket, 2 plants in each bucket, only for the first grow, second grow I add 2 more buckets with a pump each as well then I have 1 plant each bucket, they all be 38.4G/H if that is good enough, if not I go higher...



its been a few years since I been at this hobby

the very last grow I did was 4 gallon bucket 4 plants 480w CCFLs, 30G/H air pump

one plant didnt come out so well, only has like 10grams

total about 5.5 ounces, the box was rather small, 1m x 1m x 1.4m, after putting in lights fans and filters you dont have much space left in it, and I wasn't sure if I have enough root space nor enough air pumping, but they were very healthy looking and was very nice smoke


this time.... 2m x 2m x 2m Tent, 2 blue 2 red ccfl's around 900 watts total

the CCFL are loan from a friend which switched to LEDs, just to get me going for now till I have the fund for a Full LED setup..

got 40 gal/hr pump in 4gal bucket, its like a jacucci, should be good enough

some say litres and some say gallons but all of them have the watt rating and I personally like to use the formula of 2 watts per gallon minimum.Right now I have a 35 watt pump in a 5 gallon dwc bucket and its producing super bubbles

I have seen some post saying 1 watt per gallon but I have also seen root problems associated with low oxygen levels...hope this helps..

Watch this, you will never buy another airstone! Pumps come much smaller than this one with similar results, very dependable. I have owned several sizes, get a good brand name, not a China special.

the ones I'm using now are from a hydro shop online, seems to be doing the good well so far


that pump and airstone is brilliant, where can I get one

you can't go wrong with that

how is the sound with the venturi system? I have my grow on a 2nd floor appartment and the buckets send sound downstairs thats terrible. I have used rubber mats and all the tricks, maybe using this would remove the vibration?
