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

Intelligent Growing Systems IGS-061

I sure could use an environment controller to coordinate all this shit!

wassup dirthawker, i was wonderin wat website u got ur lights off? im going to do wat u are wit ur system. 4 600's with co2, dehumidifier and a.c. for the flowering room. if u could guide me thru it a lil id appreciate it very much. Thanks peace!

I'm curious to what fan you ended up with to cool the 4x600w's.

Have you tried measuring the temp of the exhaust to see how hot it gets?

Glad to help..

I bought all my lights and equiptment from my local hydro store.
600 watt 18x18 aircooled hoods.

my light cooling fan is only 435cfm..i felt the air before i plugged it into the roof vent and its hot! my room temps have been perfect.
it varys depending on the outside weather but stays in the mid to low 80s.

4sure.I jus got a new 600 watt 6"inch aircooled hood. I also have one i had frm my last grow. then im gona get 2 more then im set wit the lights. I also bot a 740 cfm vent fan, shud this be good enough to cool all 4 600's?

Hey Dirt, where did you get your netting?

I got my netting at the hydro store.

Am i trippin? my 20lb tank is still not empty and its been 3 weeks.... or am i missing something? the little ball still floats when it turns on....i just assumed that when the ball no longer floats is when its empty?

somebody tell me?????

Not sure man! Will be interesting to see how adding a controller will affect usage.

I've been using CO2 for a week now, with the exhaust fan going at minimum speed, so it has been running pretty much constantly at 3CFH trying to maintain 1500ppm but only reaching about 1300. So far I haven't seen the pressure gauge move down from 900 (or whatev unit) yet! At this rate it will last me 2 weeks easy.

I thought it was because my grow room is small...

ahahah! I'm totally out--must have jynxed myself. I think the pressure gauge was stuck.

8 days later and time for a refill. Will have to seal my room better. Money well spent. I can tell a huge difference in growth. No more tip burn or nutrient issues.. these plants are dark green and really taking up the nutes.

I must be calculating wrong or something...my co2 tank has been set at 1.7cfh 30 minutes on every 3 hours...its been a month and its still not empty?

Hey which CO2 calculator are you using?

http://www.hydroponics.net/learn/co2_calculator.asp

This one? I'm not sure if it works right... if you put settings in and calculate your on time and how long a bottle will last... then change the PPM and recalculate you get the same bottle last time regardless of the on time.

You have a lot of plants.... maybe they are using up the CO2 faster than you think? Maybe they deplete it within 2 hours and starve for 45 minutes? Just a guess.....

I finally settled on 1 hour off, 15 min on for the exhaust timer. The smell was fairly strong this morning.

I like the idea of hardwiring the carbon filter+exhaust fan so that it is constantly supplied with a minimal amount of current to drive it at a very low speed (maybe 50 cfm or better yet 1/3-1/4 speed it would take to empty the room in one hour), during the day cycle when it would typically be off. When the exhaust fan is supplied power (nightime) it would then act like normal.

The CO2 controller can make up for the lost CO2 easy enough, which should hopefully be minimal.

This would be a way to prevent any smells from leaking out, and hopefully help the other issues.

Anyway... just ideas at this point. Solve one problem and create two more!

Yo - rep - you can hardwire one - or go to your hardware store and pick up a router-controller... I laughed while looking through the 2009 Hydrofarm catalog and saw they are selling it as this:

I got this exact same model at the hardware store for $25. I use it on a 6" vortex - and crank it way down and run it often. The air to carbon filter ratio is better this way too - though it takes longer to exhaust humidity and stale air. I use the Hydrogen CO2 generator - so a little extra CO2 generation is not to costly... (plus my old house still gets great CO2 from the pilot light in the heater!)

Like all of you - I am constantly striving to maintain "the environment" for the kids! Great discussion...

On the venting/cooling note - have any of you guys running sealed and vented reflectors tried the water cooler from HydroInovations? This looks so trick! Basically - you hook up this water-cooled radiator to one end of your hood duct and a vortex to other end.... If the water is cool enough, not only will you remove 100% of the heat generated by the light, but you can actually add cooling to the room! They look so cool - I want to try one - but don't have the right situation for one right now... my local store sold the dozen units they got in instantly. I wonder if they really work?

I tied all the tops down on my first batch of sour diesel. And the other lower tops reached the lights the next day..lol there is only 2-3 sour ds in the back on this batch..... tall sons a bitches!!!!

my 2nd batch of sour diesel is 14 plants at about 8 inches and ready to go into the flower room. Beacuse these sour D are sooo tall i was thinking of pinching the tops before i move them in tonight? what would you do? i dont know if they need time to recover from being pinched before moving to flower?

yikes...

Topping/Pinching will stress a plant, hopefully they won't turn Hermie on ya. But that's your only option right now, damn those are some tall plants. Don't think I'll ever grow Sour D, not after those pics.

HERMIE!! holy crap! i hope not i just piched the little bastards.

just dont do it during flower. pinchin them and toppen them a little wont stress them to much. Ive never had it turn one hermie yet. but I dont do it a whole lot. exept the experimental freaks I do

I piched a minute ago...they are due to go into the flower room tonight..... do you think they will be fine going in tonight?

I'v seen ppl pinch em 2 weeks into flower without any problems, not suggesting you do that, but I wouldn't worry too much. Your girls should remain girls.

6 days no update? dirt wher r u? lol
Great job by the way!

your fellow stinkbuddies demand some bud porn! hook a brotha up!
