DirtHawkers first indoor aero/nft "stinkbud design" medical grow

Dirt...

What size co2 tank did you get? Any idea how long it will last?

What do you think of the carbon filter? How do you have it scheduled with the co2?

Lots of questions

I just got the 6" carbon filter and it's made a world of difference. Smell is gone; temps way down--time to throw in some co2 tanks and throw out the co2 generator hehe. Someone I know ordered a 350w LED panel to test replacing a 1000w HPS for summer--will keep you posted

The carbon filter is hooked to my exhaust,, the exhaust turns off 5 minutes before c02 injection and turns back on 2 hours and 45 minutes later before the next c02 injection. It runs nonstop through the night. The dehumidifier is on 24/7.

I think the tank will last a couple weeks ( i got the 20lb tank)

Hey man, I'm glad everything is working out for you, I'm very curious to see that sour diesel.. how do you plan to compensate for such a long flower time? I'm building my stink system as we speak and I'd love to grow some sour but I'm scared of the flowering times haha.

Keep us updated!

yes, i've heard SD takes 10 weeks flowering? can you finish her at 9?

oh, and my father in law just got some Cheese Wreck. we're doing an outdoor grow this summer.

Dirt!

It's been a week at least--how is the CO2 affecting the grow??

hey any one know were I can find a green glass light bulb?

Try a party store like 'Party City' or the one store in the mall.. 'Spencers' i think it is.

I can see a big difference in growth already...the buds are fattening up nice.

At the moment im taking a shitload of clones,,sour diesel, og kush and blueberry....i want to add a 4th flower system and put one strain in each of the next 3 units that become available...
that is each unit with nothing but one strain.....
i think i can do it but, there will be alot of fallen soldiers in the process. I will have to toss some plants after taking clones just to make it work. wish me luck.

Thanks guys for the help...i agree a bigger fan would be money well spent , especially with the summer coming..

i made a couple rough drafts of the fan configuration...tell me which one would work best?

do they make 6inch splitters?

it might be a bit late to chime in on this issue... but you might consider putting the fan between the lights; two in front, two behind. I run 460cfm'ish fans (one per 2 lights) between a couple 1000w's. I've heard some say pushing air is better ... and other's say pulling air is better... so i decided to split the difference. i'd be concerned about the heat (hot air going into the blower) but some nice chap said he had a guy on the phone that made these fans and it sounded very likely that the temps would be no where near hot enough to effect the fans performance or longevity.

sometime the soldiers have to take one for the team! but do try to keep ur moms alive till you know the clones are going to make it.
.

Well i went with the first draft above witha 430cfm fan, pushing ...so far its been perfect,,,although the weather outdoors seems to dictate the temps...last week my room was a constant 88..this week its colder and its about77....a speed controller might be my next purchase. AS for clones i am at 100% so far..

stinks system is the shit.

the only reason the fans need to be pushing is. the heat blowing on them drys out the oil on both ends of the little utility motor. It just makes them fail more often. I sell the small 4" 6" 8" booster fans were I work and I see customers bring them back with burned up motors bearings cause they ran dry of oil. thats the only real reason I can see. nice lookin so far dirthawker. peace

Does anybody else ever wonder if there co2 is being dispersed evenly? I have mine hooked to the back of an oscilating fan blowing over the tips of the garden, but i always wonder if the co2 is just getting blown over and away?

also this netting i did seems to be working great..i will take a pic in a little while.

I've noticed that centrifugal inline fans online are rated at 170' f.
I've also been told that the thermodynamics of pulling the air vs. pushing is in favor of pulling (though I can't verify this).
I believe that most decent inline centrifugal fans designed for growing have sealed bearings, do they not?
I can see what your saying about cheap booster fans, but I don't think this logic applies for quality inline centrifugal fans.

Wait until you get a controler/CO2 ppm monitor--it is definitely being disbursed evenly. I've been playing with my new toys for a few days now and, even with minimal fans blowing, the CO2 has been equilibrating just as you would expect a gas would.

Post a pic of the netting bro! One more thing I need to copy from youhaha

Hey Dirt, I know you posted a schematic of your light square, would you mind giving me the dimensions? Finally adding lights 3 and 4 and trying to get the light pattern to be the best!

heres a pic of the netting,,i may have to raise it a little but it seems to be doing the job..i think it will help with the yield.

torrey i cant find that schematic...but here is a pic

Hmm, me likey the netting, seems like you can definitely keep everything spaced out evenly!

I agree it looks great!!

Is that reusable netting, or did you make it with twine?

EDIT: its definitely made from twine--nevermind
