cool thread!

If you want real production but it comes with feast or famine I would run 8" pvc into 12" pvc manifolds to my rez with about 6" between tubes. JK
rockwool, enough said.
Hello. I wanted to get some input or opinions on which grow methods have their advantages.
I was reading somewhere else, that aeroponics gives the roots 99% oxygen, while DWC (dissolved oxygen) gives about 2% oxygen to the roots. Which method is more effective?
I'd say aeroponics is more difficult, because you need sprayers and its possible to break and you your roots die within a few hours if they do break, but is it more effective? Does aeroponics give better yield and quicker grow times?
DWC is kind of easy, since basically you just need water and an airstone, not a lot to mess up. Because its easy, there are tons of DWC grow reports and people showing good systems and getting good results (and bad results). Are the good results just because it is relatively simple and therefore more common?
Do roots thrive better under 2% oxygen (DWC), or 99% oxygen (aeroponics). Which one has better nutrient/air intake?
Love to hear opinions, please.
I recently bought some new 7 gallon buckets and plan to experiment with dwc and i appreciate your lead for the oxygen machine, thank youLook in the medical section on craigs list for one of these machines. Unfortunately people do not usually last very long on them.
I would agree with what has been said except about %'s. I am prejudice because I make tanks of my own design. My system with the shallow dwc is maybe one of the safest forms of aero to run. I have the drip at top and the dwc aspect to cover my ass if the pump fails on the aero. If I was a production grower with a lot on my hands I would run my rcdwc GM 3000's. If I wanted to maximize my yield and was an observant grower I would use my gm 1000's. If I wanted large plants with less hassle I would run the GM 500's (close to a krusty bucket).
If you want real production but it comes with feast or famine I would run 8" pvc into 12" pvc manifolds to my rez with about 6" between tubes. JK
if i said give me your best yielding method/system no matter how difficult, close watch needed, what would it be?It all depends on your situation. I can not have a lot of plants, so I grow my way.TK uses 4 x 4' trays,he loads them up with 12-20 plants. That same area I use 1 gm 1000,1 plant. We both get the same weight because he is a maestro,me I just show up at the end of harvest. He has to maximize everything while I am more or less on autocruise.
The best system is the one you feel the most comfort with. My system requires money,others require more skill.Though my sys without being real observant is a disaster waiting to happen. JK
lol,,, Well if i put a waterfall in there it would be the super duper rdwc system with extreme 02 then :)For extra aeration Check out my video on Super Recirculating Deep Water Culture
All very valid points and water temps extremely important...15 years with hydro cannabis, all types of systems. What do I come back to every time? DWC. Why?
It's simple to set up and simple/cheap to run, with outstanding results. No large pump (electricity) like rdwc or aero, less finicky with nutrient absorption. Biggest issue I see are people running multiple buckets, each requiring it's-own and/or differing maint.
Failures in dwc are mostly due to the following reasons:
Incorrect res temps, it has to be between 65F and 69F for trouble free growing.
Too much air being pumped through, causes artificial rise in pH from too much CO2 making carbolic acid. (unplug pumps until pH of nutrient stays stable)
Incorrect nutrient profile causing deficiencies. (The closer to Mel Frank's numbers the better)
Incorrect pH handling causing deficiencies. (Best results come from a pH swing/cycle from 5.4-5.8 and back, completely controlled through the addition of nutrients, not pH up/down)
DWC, when properly run, is the most simple, inexpensive and effective way to grow cannabis I know of. :)
Still more points of possible failure than a tub with some airstones in it. Leaks, floats and controller failure points, as well as additional nooks and crannies for biologicals breeding problems.I find the waterfarms as a recirculating water tube to be everything you said but its recirculating, WITHOUT A WATER PUMP,.....
leaks are just free rh in ther room. Your toilet float could malfunction to but how ofter you get to work and someone excuse id the toilet float....Still more points of possible failure than a tub with some airstones in it. Leaks, floats and controller failure points, as well as additional nooks and crannies for biologicals breeding problems.
Uhh, no. I set and forget and spend a ridiculously small amount of time with dwc.You right with your anology but understand what your saying is hand crank windows are less prone to failure and im saying that i will gladly work on it once if need arrises, where you will still be cranking away.
Yes, it does, which is why I don't recommend it. One res per strain and light.I couldnt imagine trying to individually check and maintain each bucket. It would change the whole aspect of growing for me.... it would suck!
Doesn't matter, people have issues with breeding biologicals in rdwc, even with a water chiller maintaining 68F.As for your breeding ground, 68 water temps.....
