DIY 1200watt Under Current with DJ Short Bluberry, Sweet Island Skunk, Sour Diesel

Yea as far as I know temp and surface movement are the keys to good DO, air stones actually do little to keep DO up besides stir the surface. What kinda air pumps are you using? any plans for CO2?

Yeah, I really like this system for the DO properties as I feel that's really
key to keeping healthy roots, and inevitably a successful harvest.

For circulation I'm using a 495gph inline pump on each system, as well as
some generic aquarium air pumps I got from the pet store. I think next go
round I might try a 800/900gph pump as I feel the water could be moving
faster.

I would love co2, but the wife already capped my budget for this round and
since were not growing for profit I might need to wait a while until I can get
the right equipment. For now I do have some exhale blocks (home brew co2)
that supposedly add a little extra, and for 25 bucks I figured two couldn't hurt
unfortunately I don't have a co2 ppm meter for now and don't really have any
idea how much they add if any.

roots looking good so far, no sign of dreaded root rot. Do you have any plans to fight the root rot if anything can come up? Thats the 1 thing that can kind of go wrong with a UC type rdwc system. good luck

Shouldn't have root rot issues with a res temp of 61* with chillers. The great white/hygrozyme/zone
should also assist in keeping things white. I check them again tonight and they're absolutely
white with no sign of issues. But that in fact might be one of my issues with the system if
I run out of room in the 5gallon buckets for root growth and the 2" pvc begins to clog. Deciding
if next round I want to go ahead and order 8gallon square buckets or if I just wanna try to do 9
sites under each light and lower veg times.

Thanks for input!

that great white will fuck some root rot up for sure, saved my very first crop....dispotion84 looking very nice and clean, lovin that.

whats your success with hygrozyme? can somebody school me real quick on this product?

very nice grow man very clean +rep for using hemp depot

First time using great white but I've heard good things, probably
a bit unnecessary, but I definitely saw a difference in the water
uptake after application.

Hygrozyme is great, it was another one of those products that
many growers I know swear by. It basically just takes decaying
materials in your reservoir and breaks them down into usable food
for the plants.

Thanks, I appreciate the love. Hopefully flowering goes really well
and I'll have some nice bud porn for all.

Can a brotha get a pic from under the screen?? I'm curious what the underside of your SCRoG looks like!

How high up are you keeping the lights? Seems they are oddly stubby for what appears to be HPS that high up.

About 16", the height is mostly genetics with lots of topping.

The blueberry is super heavy indica making a nice naturally short
bush. The topping has also helped keep them very stalky.

The sour D is quite stretchy between nodes by nature and I have
topped them much heavier than then blueberry to help keep their
height under control. The largest of the sour D has about 30 tops
coming through the screen.

How do you clean the buckets if they are all caught in the same screen? I was thinking of keeping the plant screens seperate.

I really can't once the screen is up, I checked pretty vigorously before I put
it up and the system stays damn clean. I'm also running flora kleen ever 2 weeks
to help keep the nute buildup down and keep things clean. Between that and the
beneficials and enzymes things are fucking clean. I'll get a picture of my control
buckets next time and you'll see how clear everything is even with all the addatives
i'm using.

Hey I believe you. I was just wondering because this is my first time. But like I stated, I think I'm going to do each seperately.

Not trying to act defensive just confident in my methods. The system really
isn't that much like other dwc as the circulation rate is very high so things
stay mixed up very well and even my powder nutes like great white get a
good mixing and I don't seem to ever have anything sitting stagnant on the
bottoms of each res.

I had thrown the individual idea around but even if they were individual I
would still have a hell of a time opening it up to work on the reservoir below.

From the looks of most kits I'd say they are not made to clean while growing either. They don't even give you an extra bucket or something to stick a plant on while you clean. I guess everyone just cleans the res and use enzymes and bacteria (and pest killers) to ensure a healthy grow.

Well honestly on any system I've run it's never been necessary to
clean out mid grow. As long as you're not getting slimed/rot things
should be fine just cleaning between grows.

Oh, I thought they had to be cleaned every 2 weeks. I guess they only need the water changed. Yep, I'm a newbie.

Well, a lot of people like to flush frequently to help cut down
on buildups and help with taste. It's not hurting anything to clean
them frequently, in fact cleanliness is a great thing to have. Just
when plants get huge it really becomes hard.
