Hi Everyone! Some info leading to my Question
This is my very first grow. I have a 3.5x3.5x6.5 tent(80 cubic feet). passive intake(fresh air/wind from window is funneled to tent with duct but without any fan which means no wind no air, just room air) and no fan for exaust which I think I DO need-but am ready to purchase one now-just not sure what CFM or opening size needed for what I want to do.
I have a bat-wing, a 400 watt MH Digibulb( I'm undecided on a cooltube w/wings vs blockbuster hood, 6 or 8 inch), and a 400 watt Quantum ballast are in use now(thinking of upgrading to a 600 watt set-up sometime in the future).
Ebb-n-Flow system has been running smooth( keeping an eye on PH,TDS and adding water to res), a 25 gallon res, a 2x3 concrete mixing tub for a tray on a pvc table(eventually will get a 3x3 tray). mini-plug to 4"rockwool in Hydroton in a 8"pot with mesh bottom. The tray is set-up about 2 ft off the floor, res under the tray. Two 7 in oscilllating clip-on fans circulate the air. Also have 2ft 4 bulb floresent and plan to buy a turbo-klone soon
Entire House and Garden nute line was in use.
I have only ONE single healthy, robust "The Ultimate" strain plant(a sativa) started from seed(first successful germination after 3 earlier failed attempts) in the middle of July. It's now the End of Oct, it'll be ready to cut end of January if I flower now!(12 wk flower) It'll be freezing by then(Im on the Northeast coast).Originally she was gonna be a Mother plant but I was not able to get another smaller tent for her in time- hence the delay to flower, plus I dont want to deal with tall plants anyways. I've decided I want new seed strains to do a S.O.G. with Indicas like Grand Daddy Purple (G.D.P.).I read some guy's grow journal where he grew like 40 single cola GDP in a 3x3 tray in 4" rockwool with little or no veg time. N.F.T I think but I will adapt to Ebb-n-Flow somehow. My jaw dopped and I fell in LOVE! That is EXACTLY what I want!! so I want to finish with this plant I have now. but havent figured out how or where to keep mothers for so many clones
I think I over-vegged her for my space so I figure to flower now( I DO have 400 watt HPS Digibulb ready) because she is 3ft + tall now. Way too big. My room height is 6.5 tall, minus the almost 2 ft for res and another foot for "hood" clearance, I only had about 3.7 feet of space for growth and (this is WHY I decided to make the change. and felt have to flower now before the plant height gets unmanagable)the top was touching the bulb which I dimmed to 250 watts so the tips havent burned yet...so...Earlier today I just changed the whole set-up to a DWC. took out the res,tray, and table so I got myself an extra foot or so of space when I switched the 8"mesh bottom into a 10"net-pot with bucket lid on a 5 gallon bucket with airstone inside. A nice DWC. I think she seems to be taking it in stride. no bad signs of stress
I also understand the the plant may grow substantialy during the flower phase so I may be forced to start bending the main cola and other branches and do my best to try and get some light to the buds that will appear
So Here is my Question----------
I finally got some money for equipment so right now im ready to purchase some supplies that I need like an inline fan for exaust, a hood or cooltube and a carbon filter for 80 cu.ft to be properly ventilated of light heat and odor. should I have a 6" 400+ CFM inline fan or 8" 700+CFM inline fan connected to a fan speed controller with a y-adapter to hood and 700+ CFM carbon filter each with one 45 to 90 degree angle leading up to the exaust fan spliting the work-load on the fan --or -- should I run the exaust from the 700+CFM filter then a U-turn into hood or tube then 90 degree turn to hanging 6" 400+CFM or 8" 700+ CFM exaust fan with speed controler. will this be enough to cool the light and scrub the odor without killing the fan(heat) or filter(CFM)?what if I put another filter on the other end of the exaust as to double filter the air or is that over-kill?Is that even do-able?What effect would that have on the inline fan to have to suck through a pre-filter and blow out yet another pre-filter ?
and is it adviseable to attempt flowering this cold time of year? what will happen?will I have a lower yield from colder temps? yes im indoors and probably will have heat but not always. air must come from window and the room the tent is in (plus cigarrettes are smoked sometimes in the room)Do I need fan for intake like a booster fan?odor is a big NO-NO and i expect the plant to start kicking soon
Help please I need advice Thanks!
