I was playing around w/ the idea of running a huge recirculating dwc ebb n flow hybrid system outdoor next year maybe use a 30 gal garbage can instead of a bucket... has anyone attempted this I'd love to here some testimonies.

I wanna see this also.

Hardy024 · #3 (**permalink**) Sep-10-2008, 15:26

I havnt tried that, but I can almost garentee there will be outdoor hydro next year in my grow area. Thanks for the idea man.

Try a drip-to-waste outdoors, or plan on a really excellent filter, and don't forget your calmag if you are running rain water!

d4twamp · #6 (**permalink**) Sep-15-2008, 12:10

I'd probably be using tap water, I don't know what the levels of cal or mag is in my tap water. I do have some cal/mag . I have also thought about the algae that will more than likely present itself in a outdoor hydro application.
I'm wanting to build a greenhouse for my outdoor so I can still control the photo periods and the heat in the summer as it gets up to 118 here.
Could you elaborate a lil more on the drip to waste stinky. I heard something about it before but wasn't interested at the time, already too much useless knowledge in my head trying to find find it's purpose. thanx for the reply I thought I was all alone in here.

Lol!
Drip to waste is a pretty easy way to avoid clogs that you get in a recirc system from ALGAE!! (and other gunk).
Ebb n flow is fine too.
Either way, you need your res to be lightproof and also have a lid that fits well. And your pump should be kept in a pump bag to keep crap out of the impeller.
If you can get to the parts to clean them with a stiff brush every few days it will be easier- concentrate on the drain and the pump, and if you are using drip emitters, give them a check often as well.

Typical drip-to-waste would be something like coco fibre lightened with perlite, dripping to 10% waste on a timer.

Ebb n flow would be easy using containerized hydroton in a tray that is set up so that you can move the containers and clean debris out regularly.

The greenhouse environment is definitely easier to control, but you will have a fun time with heat, that's for sure...

I was thinking of digging out a hole in the ground and building a box to go in the hole the box will have a hinged lid and will accommodate the res. then use maybe a 30 gallon garbage can as the grow cell which will have at least 2 inch drainage out the bottom and cascading back to the res. I already use a filter bag on the pump in the res indoors and am anticipating alot of algae out doors... hoping the res being subterranean will keep the temps down a lil, as a chiller is not in the budget. I think ebb n flow might get a lil to hot in between cycles so i'm contemplating doing a constant recirc. w/ a crap load of o2 bubbling. I'm just curious to see what can be accomplished in hydro with free light, and air

thanks again Stinky

have you looked at Mega Farms(GH)? water farms but 10 time bigger (prob. more) i have seen outdoor hawaii hydro using mega farms

Hardy024 · #11 (**permalink**) Sep-16-2008, 11:25

So from the outdoor dro youve seen, medigrower, does it make a significant difference in; -potency -yeild -height -bushiness -crystals or anything else of significant value apposed to plain indoor hydro plant?

I would like to experiment with this a little. I may get a little more involved. maybe I could isolate an area of a fuckin brook or somthing. add the nuts in the isolated area, with tiny ass holes to keep it a lil circulated and itd be pretty bubbly. theres a few ways of going about this, but for now im thinkin small scall.

Idk who this guy is if this pic comes out. just somin i found on google. it doesnt say how long theyve been around, and it appears to be a tomato plant, but without knowin the age, I cant quite tell if its any diff then indoor hydro. tell me what you think.

**stinkyattic** · #12 (**permalink**) Sep-16-2008, 11:35

Betcha that's a NFT system almost identical in setup, if not in scale, to one I used to work on at a hydro basil greenhouse. You are limited to plants of a rather small size, before the roots clog up the gutters and take the 'F' right out of it haha. (Flow)

If growing pot in one of those, you MUST start flowering from newly-rooted clones with 2 or fewer weeks veg time.

Another thing that occurred to me is to take VERY good care of your beneficial organisms in the system, because you will be less able to control other pathogens- maintaining a healthy flora in your res and pots is key.

d4twamp · #13 (**permalink**) Sep-16-2008, 20:00

Thanx for chiming in , yeah that does look like NFT , "take the F right out of it" you crack me up stinky...the beneficial organisms problems you speak of would probably be due to the warm temps huh? I use some beneficial bacteria etc trichoderma/mychorrizae is this what you mean...

**stinkyattic** · #14 (**permalink**) Sep-17-2008, 09:12

The warm temps and the fact that it is outdoors mean you WILL have bacteria and fungi, so it's important to add BENEFICIALS to balance out the litte ecosystem you have created in favor of green living plants. So yeah, those are the ones you want. Something like 'SubCulture' is a good beneficials package for a hydro system.

Charles U Farley · #15 (**permalink**) Sep-17-2008, 11:54

The one concern/question I would have about this setup is temps.You mentioned that it gets very warm where you are at in the summer.Stinky alluded to that in her last post.Developing benefical bacteria will be very important (IMO)but I would postulate that water temps over 90 degrees would create a ton of problems.Its a great idea though,I would really like to see how things work out for you,keep us informed.Take care and be well,most of all be safe.

**stinkyattic** · #16 (**permalink**) Sep-17-2008, 12:07

I think he was planning to sink it into the ground. An awning or shade over it, and a silver tarp to reflect sunlight, will also help keep the res cool. Worst would be a dark-colored res lid in a sunny spot.

Weedhound · #17 (**permalink**) Sep-17-2008, 13:07

Charles pinned it for me.......I do hydro for control purposes........along with indoors for the exact same reason. I would absolutely HATE to work like a dog on my hydro stuff only to have the weather.........completely beyond my control........screw my grow.

d4twamp · #18 (**permalink**) Sep-17-2008, 18:01

I just wanna see what would happen, I might try it out next year...maybe by then I'll be able to afford a chiller... anybody have any thoughts on a good strain for this...

Outdoor hydro is great if you prepare correctly. Where I live it gets up to 115 for days at a time. You've got to keep the res cool but you don't want a big difference in temperature when the system cycles. Continuous flow during light hours is good if you use a chiller full time otherwise the pump will heat the water and make things worst.
Pythium (root rot) is the big concern, I tend to deal with it in an aggressive preventive manner, 35% Hydrogen Peroxide in small doses will keep it at bay but will also kill off the beneficial bacteria, so use nutrients that are readily available to the plants.

DWC is a good low cost way to deal with the heat. I grew lettuce and tomatoes in a DWC bucket with styrofoam rafts, all the way through summer. The lettuce stretched because of the heat but it also puts off a natural chemical that helps prevent pythium. The tomatoes where amazing and had roots that where 4 feet long when I lifted the raft out of the water. The res would get up to 80-90 degrees during the day and evaporate the water like crazy, up to 5 gallons a day.

This is the ebb and flow system that I modeled my system after. But in 115 degree weather I've found drain to waste drip setups combined with an absorbent medium to be the better solution and it eliminates the cost of the control bucket.

Complete Multi Flow bucket systems at discount prices

These usually come with 2 gallon containers I wanted 5 gallon buckets so I made my own.
Here is where I got the control kit.
Ebb & Flow Control Kit

I purchased black 5 gallon premium buckets, the inserts, the fittings and tubing from a local source. I installed the kit in another 5 gallon bucket and purchased a large Brute garbage can for the res. It works very nice when used with expanded clay.

The price is about the same as a prebuilt setup but my DIY allows for much more versatility. You have to supply the pumps, timer and wiring. Check out the instructions before you buy the control kit if you question your ability to wire it yourself.
Hope this post wasn't excessively long, I could go into much greater detail but people would probably fall asleep reading it.

Outdoor hydro is the best of both worlds, free high intensity lighting, all the fresh air needed combined with the control and power of full hydroponic solutions. Your moving into the epithelial of plant culture.
Good luck

d4twamp · #20 (**permalink**) Sep-19-2008, 16:32

I'd rather use fill and drain fittings inside each grow cell, alot cheaper than a electrical e n b controller. either drip to waste or recirc. dwc is the way I'll go. completely DIY of course, it's my new found hobby

no thought's on a strain for outdoor hydro

the image reaper · #22 (**permalink**) Sep-26-2008, 08:09

I've played with the idea of outdoor hydro, but I suspect trying to keep up with algae control and constant evaporation would be a pain in the butt ... something to consider

d4twamp · #23 (**permalink**) Sep-26-2008, 17:41

My thought's too TIR, btw you on the road yet

Bump Bump Bubabump

Is there still no thought's on what YA'LL would like to see or do well (strain wise) for D4TWAMP's 2009 outdoor hydro attempt... feel free to leave your $.02...

Weedhound · #25 (**permalink**) Oct-02-2008, 15:22

ok sorry for threadjack....

Trinity you may want to consider using something like Canna's Cannazym to prevent root rot vs H202.....it will do just as good a job for you without killing off your beneficial bacteria.

End of threadjack.......sorry d4....
