DWC with no Air Stones! you Heard me!!!!

well RDWC really using waterfall effect for DO less equptment less hassel less shit that can go wrong, helps keep temps down and im using a version of heisengbergs tea, that guy is a wizzrd i tel you, just throught id share a few photos, the strain is a heath robinsons V3 youtube it, looks tasty as , growing in a home made RDWC system, started as undercurrent but changed as i have been reading alot about dissolved oxygen and airstoine, flooming, waterfall effect and decided to buy a DO meter to measure the most efficient way of getting ~DO in your res, airstones being last on the list hopefully as they are also a cause of pythium, root rot, its a airborn disease they bring it in if temps get to high they punce on your roots, ive had it befor, so my grow now runs fully off of 1 x 3000LPH pump for all MY DO needs for 4 plants that have just been fimmed a few weeks into veg, heres some pics!!










DO meter... no battery for it yet will have results tomorow!



roots looking nice and healthy and thats after a bout of algae due to a light leak, the EWC tea sorted that right out!!

looking good m8

Looking forward to the results

Il updat every week active on 2 other forums so itl be a chore, only came here to see hiesenburg but there seems to be a good dwc following here so why not eh? Any questions on the system or whatever fire away!

dwc is the shit on this forum buddy a few people have been inspired to change over looking at my grow and what dwc can do, looking forward to be growing alongside you mate

Well,

I liked you until you said your on other forums....

jus bustn ur nuts dude....


Actually, Im wondering what are you reading? Id be interested in checking out the material your basing your ideas off. You know growers are always lookin for that next method. all tho I think they all have their Pros/Cons.........

But this is the first im hearing of this airstones can be bad thing, I always figured they are mandatory to provide enough air. but I am fairly new to the dwc,and undercurrent systems.


I just like the simplicity of Flood/Drain.....

there not entirely bad, ive grew 3 DWC grows were ive surpassed my greatest expectations with shit airstones, 50oz dry from 8 5 gal DWC buckets run off a hailea 30lpm pump! first attempt at dwc lol

but over the grows ive been reading and experimenting and airstones do not actualy add DO (dissolved oxygen) to your res its the bubbles bursting on the surface and the aggitation of the water that causes the aior surface and water to comeinto contact and echange o2 for co2 thus enriching ur solution in DO so if my buckets are running.......

5 stones, 1 3000lph pump 1 hailea air pump for the stones all needed air line and manifolds OR

1 3000LPH pump creating the same amount if not more DO for all the same, which is more efficient? i have a DO meter and i will run a experiment and put it up for the non beleivers, look up flooming v air stones as well, it all koi carp pond stuff but highly relevant to hydro as well especialy DWC

and to answer were i get my ideas from google heath robinsons grows, guys like the pre breakdown tyson of growing lol

WIIMB- cant PM you or it wont let me find your started threads mate to see ur grows itchin now after seein that pic on ya profile lol!!

i know i am one of the ones who were inspired to change over to DWC,and it was exclusively due to this forum,and when my current grow finishes i'm going to do a RDWC. i just ordered everything i need yesterday.

Personally, I prefer Flood & Drain, with an external rez. Much easier to maintain, clean, replenish, drain, chill, adjust pH...

She is growing in lava rock, which drains quickly, but has millions of air pockets to keep roots moist. Also, the quick drain allows me to feed her roughly every 45-60 minutes during lights on. This caused explosive growth.

I am using bulbs from the aquarium industry which are much stronger with better PAR than horticulture bulbs

I eventually plan on getting a fish tank waterfall to replace my air stone, but since it is away from the roots, I don't have the problem RDWC peeps have. The benefit of the waterfall is that all the nutes cycle through

She's over 4 ft wide and 6ft tall. Clearly a Sativa

My DO Meter is on the way and I am SOOOOO excited!!! What a great new toy...but for almost 400 it better do more than read my DO

4 bills for a DO meter? I'm thinking I could buy 4 huge ass air pumps and enough stones to peg that pricey DO meter and have no need for it.

You are absolutely correct, but....my employer paid for my DO meter because I was able to order it through a supplier that also carries products I use in my office. If they only carried nutrients I tell you!

OP, sounds like you have a big pump running 24/7, thats gonna heat up the water quite a bit I'd think, if its submersible anyway.

mine was 1200 got it and a hygrometer and a temp meter gigital, u dip in res all for 90 quid from a guy on ebay!!

to much DO is toxic for plants i just wanna which way is most efficeint!

ur correct, sub 3000LPH it keeps my temps 18-20 which is wht i want my friend, prob need to run a chiller in the summer though

right had a minor set back with mg locklout/def just put the ph to 5.8 and ke[pt it there gave it a foliar feed of epsom salts and they seem to be on the mend, heres the pics.........

room temp 25deg
humidity 30-50%
res temps 18-20
ph 5.8-6.2 il let it drift
EC is at 1.0 now n there eating that shit up quick!!

here they are, only a few photos as i have to use the basic uploader on her jeeso..... lol







root porn, slightly yellow due to running EWC tea but there healthy as let me assure you!!





once they grow another bit bigger i will remove all leaves affected by the MG deff, they make em look ugly lol

questions/crittisisms............u no what to do!!

This is the kind of system I'm looking at. Airstones just seem like they are a source of problems and a sub par solution to one part of the growing equation as a result. They introduce more variables and make things more complicated. Kudos. How big are those 4 going to be with a pump that size? I'm trying to figure out just what sized pump I would need realistically for a 3 tree grow (25 gallon res ala Heath) with 1 in veg at all times. Veg plant would be run in a separate system/room.

How easy is it to flush your system? That's one issue I am struggling with at the moment. I have everything else figured out, just need to figure out pump size and flushing. I don't have immediate access to plumbing in the room so it will all have be done the old fashioned way, but doing it in a way that's quick and easy - obviously a huge plus. That is one advantage most airstone systems I have seen seem to have. Easier to change out the res because there's no circulation, just buckets of water being fed on intervals with airstones in them (unless I totally missed something about some the other systems I have seen).

yeah your right mate, they add heat to res, bring in pythium as its a airborne disease!!!! and in general a system is more efficient if i need 5 leess stones airline manifolds and a huge airpump lol,

as for the tree machine id go 3000-4000lph per tree machine, are you going polytank and 4 gal basin tree machine?

as for flushing i have a 2m lenghth of hose onto my recirc pump into a 3m lenght of 32mm pipe direct into my toilet lol i fill up the bath and leave it to stand over night to refil in the oppposite way, for the last few L of stuff in each tub i cant get out i use a small 750lph hialea sub pump like a aquavac lol just tilt the tubs and pump into a watering can, hope this helps you out buddy!!

quick update, these are from saturday, they were fimmed that day, and are now even bushier, check the root porn also!!
i also pimped them up a bit with some bubble wrap mylar to keep res temps low as i have 2 x 600w over my DIY RDWC unit!







rootmass from the runt.... the rest i can hardly lift out all healthy and white though!!





fimmage.....

also the people who have PM'd me about the diy for the RDWC il throw it up when i get the chance!
