How To: RDWC/UCDWC diy (advanced)

Cheers for the reply, its much appreciated, have been studying this for a while now and gonna give her a lash all bein well very soon, And by no means man, was I saying it was gonna be easy just that ya made it look that way, and yeh I'm a little weary on feeding, topping up etc, was definitely gonna go less is more with that 1, with GH's 'coolade' and hope it doesn't turn into mission impossible keeping on top of ph+ec levels!
But without bein a torture mate, was just looking your much valued opinion, I'm also UK based and was gonna try the same sort as your 'no airstones' method, but was thinking of 5 of them B+Q totes (same 1 you had for ur rez) for the rez and the 4 babies (or would i really need the rez bigger and then would I get away with the same size pump, i know i'll be out more in nutes but was just thinking of more root space).
I also read a couple of people saying that if they were gonna do it again they maybe wud hav went 3", I can get that size in uniseals (ha, nearly finding the pipes to fit harder to get), so was just looking to know wud that be any better or worse, or should I just stick to your sizes and try and keep er simple, also was hoping you could give me a link to that tea mixture (can't think of the name) or was it Canna all the way for you? And did you do much training wiv them or was it just that bit of lollipopping?
So once again sorry for being a complete newbie, and firing all the questions, and goin on like, but hav ta say, I've looked at some amount on various sites and I can safely say I've never seen anything like yours, or even close, an unreal piece of work, can't say enough about it, subbed for this next 1, AND I CANNOT WAIT!!!

thanks for the humbling words mate i mearly replicate all the guys ive seen like heath robinson, and all the other pioneers mate, and yes those totes are superb i can say enough about them, i went uniseals last time and tank fitings this time, tank fittings are easier to get and cheaper but id go floplast instead of the mcalpines i used as they have a rubber washer and hardly ever leak there a piece of shit to install as well and use pushfit elbows etc mate no glue needed, what size do u plan on growing them? if its they 4 pots and a res, that will equate to roughly 250L of liquid in ur sytem, so a 3000lph hailea like i used will be just the ticket, id have a overflow in ur brain res as well only thing that i done diff this time,

and yes the tea is essential matey, healthy root=healthy plants and buds.....heres a great tea thread...https://www.rollitup.org/dwc-bubbleponics/361430-dwc-root-slime-cure-aka.html

all i do is 10L of bubbled water (12hrs or so gets rid of chlorine) then add a few cups of EWC and some molasses and a scoop of greatwhite powder and then furiously bubble for 24hrs, strain and immediately add to res , do this once a week mate and then a res change every 2-3 weeks ul be fine, ph management etc is no problem mate ul be fine just keep all the levels within range and u wont have a problem

res temps 18-20 tops
room temp 25-28
humidity during veg and first 2 weeks of flower above 60% let those buds swell up then below 50% there after

and have ur air exchange 2ce per min and a good big ocselating fan in there plenty fresh air and have it moving about...

the rest ul find out as u make ur mistakes like i did lol

Yeh mate cheers again for the tips and link, ya dont kno ha much i appreciate it (just gotta quick look there at the tea, gonna get stuck into the article tonight) When you say bubble the water, just with air stones like? Then with that tea mate, when should i first start it and is that all your running or is that you with your other nutes too, or is that you're running the tea in between rez changes (is the shit like that, that i wudnt think of till Im actually doin it and then im stumped and realise i didnt think it out enough).
Googling them flopasts (i wasnt sure if they go up to 3" or not, We were actually getting charged more for 3" tank connectors than we were for 3"uniseals and theyre in the UK) just quickly there actually led me to another place there wiv you guys chatting, recently enuf i think, on about sizes etc, Again i hav to agree with your flooming/waterfall method (and this time as you pointed out, in the rez too), is that what you meant when you mentioned the overflow in brain res and if so, how would i work geting on out to the feed lines if the overflow's coming straight up from the pump, also wud 19mm be alright for the feed lines/irrigation or should i go bigger because im planning to go a touch bigger with the other piping? Would it maybe keep the flow more balanced?
And then size wise if i did get 3" sorted, should the return be half that size, smaller, or benefit from being closer to the 3" size maybe with an adjustable tapp linked in somewhere in the hope of having some control over the flow (if needed).

Or then theres another jumbo tote in B+Q, she must be twice the size as them grey 1's, should i use it as my rez or would I be safer just getting 1 of the water butts and stick with the smaller rez the way yours was, i dont mind a bit extra cost at the start, Im just trying to think of as much as i can with out hitting the overkill button, if you know what I mean. I like to try and go for the "prevention is better than cure" method, if at all possible, and try to get as close to right as i can, think a little more now + do a little less later. Must av been them mistakes you mentioned, pannicking me, lol (wudnt fancy that much flowing round a room paddling pool style, ha). Just really want to try and get it rite or like i said as close to rite as i can!
Hav a hailea hx6830 (think they are 3000), she is ready for action and I was basically on the quest for them donkey dicks i really like the idea of less trimming,(hate them hand cramps ha) You had the v3 wrapped up in unreal quick time if i can remember correctly, to me thats another reason why i agree with the whole less is more its all about efficiency and simplicity if ya ask me! Im only too happy not 2 b mucking around with air stones, pumps etc. Another reason why i think you have it sussed! Why make it any harder than it has to be?

So basically i was gonna go for 4 Veneno from Eva they reckon its a real big yielder, and very mildew resistant etc (theres a copy+paste, if your interested (http://en.seedfinder.eu/strain-info/Veneno/Eva_Female_Seeds/) dunno how 2 link it 2 ya, ha) she looks and sounds the business, 2 6oo's, probly with cool tubes or equivalent, 10" extraction,(when you say 2ce air exchange??? again apologies for the newb) whatever size for intake and try and keep loads of room between the pot centres and as you say, plenty of air flowing, hav ecotechnics digi controller there, not that impressed with them either, as had probs before with brand new 1's, (how did you find your smscom controller compared to ecotechnics), also have a meter somethin similar to yours that needs a lead i think, (gonna hit ebay).
Was also maybe gonna try a bit of homemade CO2 when they're up a touch, I'll start in aeroponic propagator and no grub for a while and then build up slowly, and then let the game begin!
Also, did you top them much mate, (think maybe in 1 of your diaries ya said ya did a bit) Or was that the result of a bit of lollipopping? Serious results I know that much! That 1 wif the Olive Oil bottle was ridiculous (lmao or what). I didnt know whether to do that or try a bit of lst, just whatever leaves less work at end and bigger buds, sounds good to me. So once again sorry bout the torturin session and the long drawn out post (lol) and takin up your time, I promise i'll quit wif the questions,(ha) any advice or answers would be much appreciated and mean an awful lot!

can you please tell me what size Danner type Mag Drive I should get to build a sillier RDWC setup?

Not overly sure myself mate as im a bit of a newb, but i would imagine you would need to wrk out your total litres/gallons and then take it from there!

Great job! + rep and sub'd.

Does anyone else have pics of a similar system. I'm still not sold on simplicity over a ebb and flow system like the Titan.

I should just build a 4 site version and see for myself huh?

Peace, pot, micro-dot.
Don't let your meat loaf.

Have you seen or heard of the Current Culture Under Current System, it would be pretty similar,

http://www.youtube.com/watch?v=O9X5zw8rxd4&feature=related
To me the model discussed on this thread is a more efficient, new and improved version of CC's with ease of use and simplicity being the main difference, plus, HAVE YOU SEEN THE RESULTS?

Good DIY tutorial, cheers

current culture is good if ur a millionaire this system total cost was £200 if that. so easy to build and maintain. one pump is all u need. to answer what size pump i like to go for 10-15 recirculations per hour a rule of thumb, depends how much water ur system will be running mate

this is the 2 ways i do it......courtesy of heath robinson

im using the second one for this new system and there working well to produce these.........

Hey sqhydro, you & Heath inspired me to ditch the airstones and also get a DO meter. But Heath noted in his drawing about the 2nd one that you're doing:

heath robinson said:

And the second plan shows a system which is easier to set up as the liquid hight in the bucket is set by the return pipe from the rez, the system is slightly less versatile than the system above because you cannot change the liquid level in the tank and its a little more difficult to drain for cleaning etc but performance wise its identical.

OP,
I like your set up but man, you need to use some pruning techniques. Get rid of some of that whispy bottom growth and lollypop the bottom quarter of the plant and it will thank you generously !!

I'd rather get more space if possible. Lollipopping is a last resort IMO. I hate to stress plants much if at all.
The only lollypopping I'd do is to remove dead or severely yellowed matter at the bottom. It could shock your
plant especially removing green leaves and big green fan leaves at that.

there are no pictures to how you auto topup system cna you post some pictures on how to keep level and toped up please, and what is an outlet clamp?.

@ sqydo , were did you get those totes from can not seem to find them at B&Q

cheers

here are totes- his res- http://www.diy.com/nav/rooms/storage-shelving/utility-storage-shelving/tubs__baskets___boxes/B-and-Q-Rough-Tote-Grey-10687749?skuId=11188455

and here are the auto pots- http://www.progrow.co.uk/acatalog/info_05354.html

could the drip line be 1/4 in stead of 1/2(20mm) would that still be enough current, was gonna do a six bucket system with a manifold, not sure if it will create enough flow?

If I was going vert barebulb what distance would you make each pot from bulb sqydro?, thanks

is it ok to run a rucdwc with a seal room co2, 1500 ppm. air pump in room also. will co2 being pump thur air pump to water kill root and plant? please advise

awesome thread man! might have to step up from the usual single tote dwc systems to something like this in the near future. thanks again!

I love this idea and the scaling seems great as well.

OP if you can list what controllers, electronics and automation systems you use or would like to use it could help me make my decision on this system.

Would adding CO2 to 1200-1500 ppm in a sealed room be a good thing for this system or would you rather leave that out?

Can you break down your exact nute schedule? I saw you use PK but what week exactly?

Thinking out loud I wonder how this could be used for a SOG, I guess you'd be limited by container size and would have to overcrowd..
