well, i bought most of what i still needed to finish the grow box today. pretty excited to get this underway. i also bought an air freshener that goes on the air filter in my ductwork, which should mask the smell of the plants at the moment, as well as the spraypaint that i stupidly used in my room without ventilation. thats a high ive never experienced before lol.
and shes painted! took forever...bought some brush on flat white today for it, since the spraypaint didnt go too well lol. gonna start wiring in lights and stuff tomorrow.
Heres some pics of the growbox. the lit up one is for clones and moms, the fit in there great (2 moms). i just need to put in a little shelf on the right side to set the cloner on, and underneath will be some storage for some stuff.
the bottom part is about 40" tall. i have the 12 sockets in there, no splitters yet because i was just checking my wiring (which works). yeah i know they arent adjustable. again, i'm trying the method Dr.BudGreenGenes did (*this is the link to it*) and if it doesnt work, i can always make little stool/stair/booster seat things for my plants to sit on. Not a big deal lol.
The only major thing i have left to do is set up my exhaust for both chambers.
The top won't be too bad, i think ill throw a couple computer fans in there, they don't smell bad so i won't worry about a filter.
The bottom though, i'm going to make a carbon air scrubber, but i need advice on a fan. i would love to NOT have to order it on the internet, because i need it quick. Also, the space in the bottom is about 16 cubic feet. Here's my questions on the exhaust:
1. How many CFM does the space need?
2. How many CFM to push through the carbon scrubber?
3. Any ideas on where to pick one up and how much it would cost?
Thanks a lot for any feedback.
(BTW, picture 4 is sideways.)
Pretty nice looking box there...
Not really sure about cfm's in this case, but the best way IMO would be an intake in the flower chamber, and an exhaust in the veg chamber, with the fan pulling the air through the carbon filter (better than pushing it)... Then of course the flower and veg room have to be connected, with another fan pulling air out of the flower chamber. This is what I would start with...
The intakes could be computer fans, but the for the exhaust you could use one of those wall mount kitchen/bathroom fans from Home Depot. Depending on temps, you could put the larger fan exhausting the flower chamber and run it around the other way, but that depends on the temps and conditions outside and inside the box.
My fans and ventilation tubing keep the light out of my cabinet, but thats something else to think about also with this setup.
Good luck:jointsmile:
I was thinking about the kitchen/bathroom fans, but those arent meant for24/7 use are they? also, the carbon filter i was planning to build was a circular can-lookin' one, i dont know how i could pull through that.
nice box jkal, I think most extractors are designed to work 24/7.. maybe not the bathroom ones, but some do actually run 24/7.. should be OKQuote:

i got my light fixtures from lowes. just regular sockets, theyre plastic and cost 1.25 a piece. the only thing is, they were in one of those "dont forget to pick this up" bins, i don't know if they put em out on the shelves. i looked for them once and all i could find were the expensive ceramic ones, i luckily stumbled upon these. I'm sure theyll have them, either lowes or home depot. are those kitchen/bathroom fans pretty loud though? the one in my bathroom is.
hey dude thanks for answering my Q :D yeah... some of them can be, always check the db rating i guess, cfm is usually a good indicator of how loud it will be..Quote:

is 4 db very loud? do you think i could get by with 50-60 cfm?

Weakest sound heard 0dB
Whisper Quiet Library 30dB
Normal conversation (3-5') 60-70dB
Telephone dial tone 80dB
City Traffic (inside car) 85dB
Train whistle at 500', Truck Traffic 90dB
Subway train at 200' 95dB
Level at which sustained exposure may result in hearing loss 90 - 95dB
Power mower at 3' 107dB
Snowmobile, Motorcycle 100dB
Power saw at 3' 110dB
Sandblasting, Loud Rock Concert 115dB
Pain begins 125dB
Pneumatic riveter at 4' 125dB
Even short term exposure can cause permanent damage - Loudest recommended exposure WITH hearing protection 140dB
Jet engine at 100', Gun Blast 140dB
Death of hearing tissue 180dB
Loudest sound possible 194dB
I'm thinking that 40-60 cfm is okay for a few hundred watt of CFL, but might not be perfect for a HPS equal to or over 400W.
hope this helps :) :thumbsup:
