pc/ultimate scrog grow yield!

The scrog screen holes are probably only 1"inch.

I changes my setup and im only gonna do 3ft tall

What's the best size outake for a 3ft tall 1ft 1/2 depth 2ft wide
Grow box for a 400w/250w
I might finish off my grow here that's why im wondering?

I have a fan but it's really fucking loud you can here out of my closet so im most definitely gonna get a better one but im undecided on a
4" or 6" which only like 3$ more.

the bigger the better save you the trouble of upgrading later IMO

Can someone compare the loudness of a 6"inch inline fan.

I have one but it's purpose its not for exhaust took it off this humidifier I had.
But that one is as loud as a big regular fan put on high(great exhaust though) but yea its a little louder than that.

i have a 4" and a 6".

i turn my 4" off during the day because it is louder than my 6" fan. i would say the 6" once hooked up to ducting sounds like aloud fan. and the 4" would be like a box fan(really loud) on high.

Ok so I will be going for the 6" then.
I do the same but for energy savings =D.
I have my fans turn off 15min after lights turn off.
And about 20min. ON before the lights turn on

So I have came to the conclusion about my micro grow plant.
She must be rootbound. Because she is still nice and green but isn't growing.
What. I dont understand is.
How is it rootbound I've seen grows with smaller pots then mine.
Would it be because it's a sativa?

no some strains do not take to being root bound but what im guessing is that not only is she root bound some of those roots are septic, from bad drainage, when you go to transfer here smell the dirt near the bottom. if it smells like shit thats what the problem is.

If It smells should i just throw it out

no just replant it in fresh DRY soil and let that mother fucker get dry dry before watering, even after the transfer wait till you see some droopy leaves.

If I put it in a bigger pot it won't fit my grow box.
So what I did was switched pots put it under my 400w.
And got one plant that was hermied into my micro grow
And scrogged it I can't wait to see it as soon as lights turn on=D

My 400w grow is a micro grow as well.
I will post pics up of all 3 plants tonight.
I still see pistils on (hope) the one I started this thread with.
So I have 2 females and one female hermie which ima
Finish off in my (accordian box)

So I went to look at the 6' inline fans.
And they are exactly the same size as the
Humidafier fan I have so it must be as loud as it as well.
I'm going to save my self some money and just keep
Using the one I have besides.
I just remembered my fan has different levels of speed
For the fan. I'm going to try to lower it one.
Pics up tonight of everything.
I'm free all day today so by 8pm I'll have them.

sounds good man,and im sure the fan you got will work fine. im assuming is something like a squirrel cage blowers, which will work fine for ventilation and actually may be a little quieter.

and thats my 6inch inline fan
the new scrog/hermied


this is my micro grow 400w/hps on the left hope still looking green but not growing. On the right miracle. All female and smells awesome.

that fan look strong enough. it not an official fan but from the pic that thing looks like it pushes air. looking like a good turn around!

Thanks hopefully she survives.

Yea its a 6" im using it as an exhaust for my 400w grow
With no intake so it pulls air pretty good =D

Anybody know why im having slow bud development?

too much food?
make sure your timer is correct and working.
your impatient lol

soil is overly wet?

dont know a lot of things man but they will pick up if you just watch to see what they like then keep doing those things.

air floor https://www.rollitup.org/grow-journals/360125-weed-science-ebook-download.html
edit: with air pots too and a nice loose soil (add lots of perlite)

Actually I stopped feeding nutes since hope
Started dieng on me.
I haven't started just straight water im planning to next week though
But just on miracle since she is the healthiest.

Now airflow in soil might be true ima read more about that.
Thanks guys.
And yea timer is on 12/12 I just lost track of when I put it on 12/12 miracle just showed
Signs about 2weeks ago I think lol

Any ideas on how to silence a fan?
I was thinking rapping around some bubble rap putting my fan in a box and
just put the air duct hose into the box.
But if u guys got a better idea let me know please
Also what's the best glue/tape I can use to put mylar on
I am glueing/taping it on to plastic not wood
Its a plastic Decker. Cab

any glue that says its compatible for plastics should work fine.

i would just put ducting on the fan some how that would be the best way to silence it.
