Hydroponics Question and Answer NewGrowth Style

Holy shit! I just checked on my seedlings. Last night they were all healthy and about 2-3" high....this morning they are drooping and falling over 1 by 1.....seems like they are dying....help please!! (They've been under 24 hour light for the first few days....just switched to 18/6....last night was first time they saw darkness.....)
Please help!!!

I have a question, Im using AN 3-part grow, micro, and bloom. I have a 70 gallon res and a 4x4 flood table that I flood 3 x's when lights on for a period of 12 mins. How much grow, micro and bloom exactly should I be using? Or what ration should I use them?

I do not use AN, do you not have a ppm meter?

Try 1/4 recommended amounts and then fine tune using your PPM meter.

Here is an easy way to figure out your plants nutrient requirements:
Here are some general rules:
1.Water level drops PPM goes up: Drop your nutrient strength in relationship to the PPM rise.
2. Water level drops PPM stays the same: You may be able to fine tune you nutrient strength, if growth is vigorous leave it alone.
3. Water level drops PPM drops: Raise you nutrient strength in relationship too PPM drop.
Like I said these are only general rules always monitor your plants growth and look for tell tale signs of nutrient burn like deep green fan leaves and yellow leaf tips. Nutrient deficient plants will usually yellow from the bottom up. Keep a journal,this will help you fine tune, waste less nutrients and improve your grow next time around.

Hey Guys....thanks ahead of time for all the info!!! I'm a first time grower, starting dwc system in 3 gallon buckets...all from seeds and under 1 600W hps after they sprout. I'm using Technaflora Plant Products Recipe for Success....supposed to be everything I need for each stage of growth for my babies. First, have you heard of or used this product, have any recommendations about it?

Click to expand...

Never used this

Second, i followed the directions EXACTLY but I still want to make sure my solution is safe for the seedlings. What should the optimum pH level be?

Click to expand...

5.8 is optimal, some drift between changes is good to allow nutrient availbility across the spectrum. Fast fluctuations in PH indicate a problem.

I just checked mine and it was 7.2. Also, if I'm using this supposedly "dummy proof" kit for nutes, and following the directions exactly, do I still need to check my ppm??

Click to expand...

Ph is way to high for hydro.
I would highly recommend checking your PPM nothing is dummy proof . . . . take that advice from a dummy

I don't have any kind of a meter for that....what would you recommend? (I'm using a simple test tube aquarium kit for my pH test).

Click to expand...

Don't have a PPM meter? Aquarium kit will work fine to test your Ph

Thanks so much for any help!

Always happy to help a fellow grower

Possibly damping off it is a fungus that attacks you seedlings and will kill 99% of them. Treat them quickly with a product called NoDamp, you should be able to get some a Wal-Mart. Allow the medium to dry out a bit too. If you treat now you may be able to save the remaining seedlings. Good luck

Thanks for the help! Seems like 50% of my seedlings are dying. I'm thinking that maybe the rockwool simply dried out before the roots could get down far enough to soak up the nutrient solution. I moved the hydroton away form the top of the rockwool and it seemed too dry...maybe I don't have enough bubbles cuz it doesnt' seem like it's soaking up into the hydroton very far. For now, I simply added some water to the rockwool cubes and recovered them with hydroton. Keeping my fingers crossed!! (and if it gets worse or spreads, I'll have to go try the NoDamp) Also, I'm in the process of adjusting the pH to a safer level.
I'm going to have to pick up a ppm meter.....what should I try to keep the ppm at?
Also, you say that some drift in pH level is healthy.....what range should I try to keep it in?
Thanks so much....any help is greatly appreciated!

Glad to hear you figured it out.

Seedlings should not need any nutrients, start with a mild nutrient solution after the first set of true leaves form.

Ph drift should be between 5.8-6.8

NoDamp is a good thing to use when germinating all seeds as a preventive measure. Seeds can get expensive and loosing them due to damping off really sucks.

Well...still not sure if it's figured out or not....little gals still havent' started to perk back up yet. It does suck cuz at least 2 of them are good expensive seeds that germinated and sprouted quickly and nicely. I'm trying to bring the pH down (using pH down that I've used for my aquarium before)...but it seems to really want to stay high. Do you think I should just change the solution and make it 1/4 strength? The solution is only 2/3 days old (but full strength) and the seedlings were first germinated then planted in rockwool until they sprouted and then put in the buckets 2 and 3 days ago once they had sprouted out of the rockwool. They all had one set of leaves after the little round ones. I'd like to post a pic...but I'm nervous to...

Just run plain Ph adjusted water for seedlings not nutrients.

One plant per square foot in SOG, sometimes more with good lighting

I now have just aquired a barrowed 400w...so pumped!

what about if i dont do SOG?

in an aero system with SOG all i do is put a "netting" about a foot/foot and a half up? That the only diff from a regular aero grow?

got me a deee lema... my 8" can fan is too loud.. how should i insulate to keep the noise down... i was thinkin boxing it in and filling the space with great stufff... or stryofoam... any advice apprec.. heres the fan and the set up

SOG means sea of green. Lots of plants with little veg time, fast turnover of high quality "cola buds"

SCROG involves netting not SOG

Thats a nice room 3 600 watters??
I imagine the buckets are you own DIY ebb n flow?
You dont need an insulated blower, just buy a speed controller. Run it about 3/4 speed and notice a huge noise reduction

that came to mind at work today.. + rep.. im a rere.. 3 1000's

Thanks for picking that one up bro

Looks great doniawon, you blacking out the window more?

Some rooms I have nailed up that foam board over the dry wall too, helps insulate the room to control heat in the summer. Then just panda film over the foam.

big yes on blacking out the window ... i used strofoam insultion and firestone pond liner rubber stapled to the wall.. also added 20 more buckets .. suckers are takin off.. been to busy for new pic lately but im way due... foam board sounds like a good idea for future since ill be adding co2 with in a week... also i could not find the variable speed controler with a female receptacle at hd or lowes.. way bummed.. i hate them hydro shop visits

Just re-wire it with a female plug, I did it to an HTG light. Not hard

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.

It's called dial a temp.

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?
