overkill for such a small setup?

[borbor]

I posted something similar in the newb section a couple days ago, nobody cares.
400 CFM active air 6" exhaust fan
347 CFM vortex s-line 6" intake fan
I plan on using both of them with speed controllers around 60% speed for noise.

my tent is 3x3x9 ft, using a 315 watt CMH (I'm thinking about adding a 300-400 watt led sometime)

where am I at with this whole setup? looks to me like all I need is soil, pots, nutes, meters, and a filter. Am I wrong?


Also my tent looks pretty crowded with the intake fan at the bottom, should this be outside the tent? Does it make a difference? I think I'm gonna put it outside anyway just because it's electronic, and low to the ground.

i'd say to plug it all in and see what kind of temps you get! the good part is that if the fan is not enough at 60%, you can just crank it up.

is that a carbon filter on the intake on the bottom? edit - nevermind, saw it's a fan. yep, put that on the outside and a good carbon filter on the exhaust, and you should be ready to rock!

just get the dirt & pots chuck in your clones or seeds which ever is available to you (clones are alot faster and u needn't worry about males) then worry about metres and filters etc as your growing you will need nutes eventually but to start with its fine to use general ferts (at least untill u turn them to 12/12 for budding) you'll soon learn when u do something wrong plants are good like that they'll soon tell u if somethings up and the more experience u get the easier and quicker you'll see a problem arising but I reckon best way to learn is to jump on in there and get goin sure it helps to read up on this and that but u really don't NEED to go getting all technical untill u've got the basic jist of it sussed then once u've got a few grows under ya belt then start adding to your arsenal all the best mate hope it all works out for ya!

IMHO you don't need the intake fan. Negative pressure is what you want. That high cfm on your exhaust is plenty for that space even with a filter thrown on. I'd use the second fan for a cool tube setup.

Do you have a separate veg space? I see that open pc there... You've got 9 Sq ft in the tent rule of thumb is 60-100 (something lidat) watts per Sq ft for flower..gonna need more when the time comes but veg should be G.

Throw a 2 or 3 clones in some 3 gals full of a nice super soil mix and water that hoe. What kind of gardening supplies do you have available?

Thanks for the read and advice man!
My logic behind the intake fan Is that I'm going for a very very quiet setup. I was kind of thinking that I had a lot more CFM than I needed so that I could turn the speeds on both fans down, leaving the exhaust a little higher to keep a bit of negative pressure. My light isn't capable of a cool tube, though it doesn't really get hot enough to warrant the use of one. does that seem legit or should I take off my active air white noise machine and attach the vortex s-line to exhaust and call it good? I kinda want to use an intake fan so I'm not having my tent passively intake air next to a litterbox. Either that or move the litterbox, which wouldn't be a problem except for confusing captain cuddles. my current plan was to run ducting from the tent under the bed I was standing on to take the picture and up to the window I had my back against while taking the picture. Also, I have some mesh shields for ducting to keep dust and stuff out.

my light, the sun system LEC 315 is a 315 watt CMH, everything I've read, and advice from one dude using a, 860 watt CMH I know in real life has told me that this should produce about as much and as well as a standard 600W HPS. I've been considering adding either an LED or one of those 200 watt fluoro reflectors during flowering, I'm not sure if I NEED it though. I've thought buying an LED might be nice since I could use it in a future veg space as well, though for the price of many LEDs I might as well buy the new 630 watt model of the CMH. I don't have a seperate veg space right now, though based on my last couple days I might. (haha how'd you guess with that open computer case?)

As for gardening supplies, I can take care of any small stuff like watering cans and sprayers, pots, spades, stuff like that. My family does a lot of gardening so I'm sure if I needed anything you could use in an outdoor veggie garden I could probably borrow from her.


my 8 year old powerhouse computer finally died when I kicked it in the wrong spot on accident or something the other day. (google antec skeleton, I'm shocked my computer lived this long in that deathtrap of a case for its last 4 years of life.) I'm sad about it. for being built in '07-08 it still had comparable specs to gaming computers today. so I grabbed that bestbuy computer in the garage, it's only displaying in red and black and isn't loading my linux disc so I think that might be a veg space in 4 months or so. brings me right back to high school.
sorry for the tangent, I'm gonna cut this, and paste it at the bottom.

You should be okay. my 200cf 4" inline at about 60% keeps my 3x3x6 tent at 70 with my 400w hps on. and thats not even pulling thru the cool tube. i left that unhooked since its winter and bit cooler in basement, but its still heated down there.
