Thanks for starting this informative post.
It has taken days of reading to get here.

THANKS for all your insights.

I am starting my first indoor ebb & flow.

8 x 4 x 7 sunhut
2 4x4 trays
2 600 watt HDS
2 yield master II's
6in rw cubes
2 - 6 ln fans
75 gal res

• 2 res pumps w/ filter bags
• 1 air pump
• 2 airstones

pH meter, EC meter
using Botanicare 2 part CNS 17 grow & bloom

This will be the flowering chamber. It is set up and is running.
It has in it ....

• 8 - F13
• 4 - Sour Disel
• 4 - Purple Kush
• 4 - Purple Erckle

I am looking forward to getting enough cuttings to get the river of green going. I will be cloning with a Botanicare 25. I still have a 4 x 4 sunhut veg room to st up with 2 T5's with 4 bulbs each. But that is still in the future.

By reading the post on RIU I have gotten over most of my problems. Such as ....

• Lights too close
• pH off - too high
• temps to high
• and others

Here are a few pics.
peace and blessings.

River of Green?? whats that?? .... your little girls looks very good and clean .. nice set up + rep ..what strain?/////////////// also thanks again NG.. i looked into that.. do i just cut the grounded cord on the can fan then wire a variable speed control ceiling fan dial in to the middle of the cord and then just plug it in the wall?? dont know if you pickin up what im puttin down but ???? can i see a pic of yours??

I love how you set up the res outside the ten, great set-up man glad I could help!

Your plants look great and you set-up is well done, lets celebrate

I see what you mean, I took a pic of mine but this is the fan controller I use.

heres one for you new growth,
ive read to not water durring or right before dark time does that mean i should turn my air stones off at night ?
ive also read to keep it bubblin 24/7

Hey Hoping I can get some help,

New grower here, I have about 15 plants that I started from seeds about 8 days ago in a DWC tupperware inside my custom built cabinet. I have the water about an inch below my net pots with 2 bubble stones. I also have a separate pump with lines directly into every net pot which runs on a circuit timer 1min on 4off.
My plants had a little overwater damage in the beginning when I had them in my clone box. Now I switched them into my box and they aren't doing very well. Some have totally burnt out and died before I had the watering timing down. Now the healthy ones are discoloring and most of them don't have enough strength to stand on their own. I had them on 24hours but now I switched them to 18/6 because it was getting very dried out. I have the temp pretty steady around 80ish and the humidity around 30%
PPM is at 200 right now and water temps are around 80. PH is in between 5.5-6

I cant seem to keep these things healthy. Any ideas?

No watering at night rule applies only to passive systems like flood or drip set ups.

Active systems like DWC require constant aeration of the nutrient solution in order for root zone to have sufficient dissolved oxygen. There is no such thing as too much water to a plant just too little oxygen. A plant draws in oxygen through its roots.

In short your air-stones should never be turned off.

What kind of lighting are you using? They look as if the were looking for light but never received the right type.

High reservoir temps can cause a reduction of dissolved O2 in your nutrient solution and cause root zone problems as well as pathogen build up. Dump the pump! You don't need it DWC works just fine without drip lines.

Also did you Ph adjust the rockwool?

ROG is a SOG that never stops. The river just keeps on running

• 8 - F13
• 4 - Sour Disel
• 4 - Purple Kush
• 4 - Purple Erckle

OOPS! PE is now 3 dropped a bungiee cord on one and that one is now a clone again under CFLs

peace and blessings

I am running a 600 Watt HPS light. I was mistaken I dont really know if it technically is DWC or bubbleponics to be honest. The water sits about an inch underneath the netpots and I have 2 airstones in there. I didnt think that was enough water so I added a pump with individual lines to each net pots. Should I still lose the pump?> What do you think. I already lost about 3 or 4 that are definitely not coming back but I would really like to save as many others as I can.
I did PH adjust the rockwool before i put the seeds in

Hello NewGrowth,

Hoping you got a second to maybe make a suggestion. I'm growing Sativa breed plants (Power Plant, Power Skunk, & Durbon Poison). I'm wondering if there is anything i can do to reduce the amount they are stretching when i'm flowering.

My setup is: Perpetual SOG

1000 watt HPS light
4x4 ebb and flow tray
1400ppm Organic Floranova Bloom
Bloom Booster from beginning of flower to harvest.
CO2 and temperature controller (hangs around 80 degrees)
Humidity usually around 50%
hydrotron grow medium
Clones once rooted go directly into flower after being under 24lights (perpetual SOG, two week cycles). Mothers also are always under 24hour 400watt MH.

These ladies grow to over 4 feet tall, passing my light which hangs 48 inches from the tray. Thanks. Peace and blessings.

whats up .Ive been rackn my brain for days now trying to figer out this nute formula.Ive been up all night and I cant find it anywhere.I have GH 3part flora sys.I know your not realy familiar with these nutes but basically you have GROW(2-1-6)BLOOM(0-5-4)MICRO(5-0-1).Ive seen people post optimum N-P-K ratios of 20-5-5 and 10-7-8 I dont know wich is right or better or whatever but nomater how you look at it impossible to get those #s any way you mix it.GH recommends a 1-1-1 mix(G,B,M)and I also saw someone posted that too but that "1-1-1" mix comes out to be 7-6-11.doesnt look to me like good veg #s to me.GH has a "FLORA CALCULATOR" on their site but the close as i could come up with is 1 part GROW-3parts BLOOM to 5parts MICRO=an estimated 16-5-13 or 2parts BLOOM to 3parts MICRO(cut out the GROW)=an est 17-5-12.(the reason I say estimate is when u ad these things the #s get pretty high and loose .1 to maybe 2 dumbin the #s down) Both numbers are almost the same, toltal diff mix and still not 20-5-5 or 10-7-8.Is the mix close enuff(17-5-12)?
does it really make a noticable diff. or am I just being too anal?

(to tell you the truth id prob just buy a diff nute setup but when I bought my aeroflow 36 I bought nutes for it(the guy at the store recomended it)and I didnt know it came with some so now Ive got over a gal of each and this sh!t aint cheap)
