i have a plant limit of 24 flowering in my mm grow , I currently have a nft/aero setup in 5 in pvc 40 site , (only using 24)

Can anyone tell me how much better the yeilds would beswitching to a UC setup?

Is UC a nightmare to cool and to change res's? since you need seperate rez for each plant how do you chill the water?

Really?


IMO If it were 1990 I'd go aero, but it's almost 2011, grow in water. ;)

BTW, UC's circulate 24/7 so no headaches to chill brah.

Thanks for the response to my post, were you saying you dont need to chill the water tho? what it its 80's in the tent? no pathogen or oxygen issues?

how much of a bitch is it to clean a UC , did you build your system or buy a premade? any diy instructions around that are worth it?

Think UCMENOW is referring to the fact that aero systems tend to be on some kind of pump/mist timer to deliver nutrient solution, whereas as in a UC roots are constantly submersed in highly oxygenated nutrient solution that is recirculating.

It regard to a chiller, it is possible to succeed without a chiller as some on the Farm are doing, but personally wouldn't run a UC without one.

There are a bunch of cleaning and DIY threads in the UC & DIY sections of the Farm, I'm sure you'll be able to find something...

Hey there Mc Puff.

Use a chiller and read the UC forum to get the answers you need to open the Doors to the UC Universe.

I have run both, unless your aero is using massive pipes your plants cannot grow near as large as UC system. I JUST switched from my aero to UC. But to each their own.

lol dates don't change how awesome aero is. the issue is aero is expensive, time consuming, high maintenance like a 20 yo blond, and you have to be technical to setup and maintain a real high pressure aero system so it's just not realistic IMO for most growers based on their dedication and knowledge.

undercurrent is simple, easier to maintain and cheaper to setup then a real true aero setup. low pressure aero is not even competition with RDWC when it comes to a limited plant count.

as for the question of which is going to yield more it's just not realistic to compare. what's your budget and how many lights do you want to run? a UC 9 EVO is recommended to have 12k in lighting. a aero setup big enough to need 12k or one that grows trees that could use 12k you will damn near need a engineering degree to keep it running lol.

also if your pump dies in aero so will your plants shortly after since there is no buffer of any kind. in a uc if the pump dies the plant starts drowning but you have a much larger window of time to identify and correct the issue. that alone makes me think i'd go that way.

My aero tanks are 13,20,28,36 gallons. No problem for the roots and I have an 8 inch porthole to look at and treat my roots. Aero will always out preform rcdwc systems. People worry about the equipment. It is the rapid growth you need to worry about. Most growers eyes are not trained for this. You need to see your plants well,and not react to the physical plant as it will be too late.
Adding a backup pump that kicks in when the first one fails will solve your problems. The added harvest will more then pay for itself. I like my aero tanks over my rcdwc but that is just me. I love to watch plants grow 3-4" a day. I also get bored easy so that is another thing. If you are attentive and can take the time to spend with your girls to learn the system,you will be rewarded. If you are a stoner without a self drive this system will run you over and bury you. Suerte JK

JK, how do you have your pumps setup so that the one kicks on if the other goes out? How hard is that to setup?

Its true thats why there are aero cloners because it straight up kicks ass. Nuff said.

Yea yea I know once the roots hit the water it becomes dwc or rdwc/rswc.

You just need to install a flow sw inline.Takes less then 1/2 hour. I get my sw from used electronic stores. Aqualogics sell them as do most electric supply houses. Flow sw are more reliable then pressure sw. JK
I also deign this backup with my rcdwc systems.

I'm not sure why everyone thinks aero is so expensive and complicated. Perhaps that is true for large scale setups but it would seem UC would scale to be more expensive with a larger grow as well, requiring bigger pumps, more plumbing, etc.

The days of accumulator tanks and expensive brass nozzels are long gone. These days it's as simple as Res > Pump > Chambers > Drain. A pump with enough fixins for 1 chamber (I'm planning on using a 20G rubbermaid brute trash can) will run you $100 + shipping and can be expanded to run up to 15 nozzles. That's fifteen chambers on a $100 pump putting out 110psi with an average droplet size of ~55 microns and the pump is capable of sub 2 second feed times with the right timer.

That seems pretty affordable and simple to me.

just throw them in 5-7 gallon pots each or smart pots. and run a drip system. use coco as your medium mixed with 15-20% perlite. this will result with best taste and yield.

Please tell us which pump you use that puts out 110 psi for 100 bucks. JK

110 psi?....$100?.....sign me up.

Sounds like a typo though, or a chinese piece o shizzle.

I saw another post where he mentioned the brand mistking. They have 2 pumps the smaller one for the price is not worth it(moneywise) They operate at 75 psi,100 psi is a benchmark and pumps really jump up in cost around 100 psi. The pump warranty is 2 years not too bad, but is voided if anything but water is ran through it. For a small observed op it would work but I would hate to count on it for anything else. JK

actually, after dealing with coco smarts pots recently, I am very pleased with the low maintence/hassle aspects of the system.
