10 day old seedlings looking great but need watering advice

[Rizlaninja]

Thanks for all the co2 advice but I was after watering advice.

Apologies Rizlaninja for the off-topic stuff. I've never done what you are doing with the drip system, so I can't directly advise you there. But as long as oxygen can get to the roots, and the dripped water isn't stagnating around the taproot, seems like it should be fine.

rizla i gave u advise in my 1st post ... maybe u didnt read . Chromophore i have been a grower myself over the years , if u search my username ull see i have a far idea of what i am doing. these arent my plants they belong to a friend i know. this guys has maybe 10 years experience growing and hes the only person i know who i would trust to get my weed off. like i said if hes raving about them ill take his word for it.

I got a couple shiny pennies.

I agree with Chromophore.
Without a parallel, "no extra CO₂ grow" as a yardstick , all you have is an impression of benefit.

A little research tells me that CO₂ becomes detrimental when >1500ppm. so, careful with the dry ice.
I also read that there is little benefit at ordinary temperatures, but definite gains at >80 degrees F.
That makes sense.
At normal temperatures all influences on the growth are well balanced.
Increasing any one influence is wasted
However, if one of them goes out of balance (High Temperature), one or more others can be augmented to restore balance.
With living things, it's all about balance.

In the heat of the summer, I port air from the veg room, to the flower room.
Why?
Because vegging plants actually raise the ambient CO₂ during their dark time and flowering plants use it day and night.

For a few hot months, I ported the excess CO₂ from my wine making room to the veg. room, which then went to the budding babes as well.

Did it do any good?
Hard to say.
I only have one veg room.

Bottom line?
At less than 1500 ppm. at least it won't/didn't hurt.
And at elevated temperatures there is definite benefit.

Aloha,

I'll second that.
Sorry about the digression.

Good news is, I've done the watering both ways, and then some.

To address your question.
Yes!
IF, (and that's a big if), the water is well aerated.
I was successful with a constant drip using hydrotron.
Tends to absorb air on the fly.

Do not try it with rockwool!

And there is no problem with the tap root entering the water.
Again, if the water is air saturated.
I do that all the time with DWC.
Full immersion is no problem.

Shallow Hal I never questioned your knowledge or abilities, I was simply giving my advice on CO2 based on 28 years as a plant scientist and greenhouse technician. I offer it freely and no skin off my back if people ignore it. Now can we please stop hijacking this thread and get back to the original question?

Cheers for that. I am using rockwool but the water I'm using is very well aerated . Iv got a quad output monster air pump with a 4" donut air stone . 2x 4" donut air stone and 2 x air lift pump for the two water drip feeders.

I was told to basically keep it damp until the tap root hits the water then I could run the water feeders 24/7. Sound about right?

Perfect. co2 feeders are a few grows down the line for me.. Lol. Don't suppose you could tell me what's the best distance to have my 300w cfl from plant top? I dint want to burn the babies.

"I was told to basically keep it damp until the tap root hits the water then I could run the water feeders 24/7. Sound about right?"

Sounds exactly right.
You have more than enough air.

My rockwool drip experiment ended with stem rot.
Admittedly It was a very limited experiment and may have been coincidental.

Use your nose.
Sniff the cube every time you pass by.
You'll know if it starts to go sour.

Use our wrist like checking baby formula, how far from light is comfy, too close too hot, just right is just right, from the tops and you don't want to burn those nice ends. Sorry about the off the road. Just spent way to much on gas.
