Thanks A Woodman. Blowing through your air cooled ventilation system mean that any leaked air is simply pushed into your garden, whereas sucking air risks unfiltered air being extracted to the outside world and creating odor issues.
Two reasons. 1. The Carbon filter restricts air flow, so filtered air isnt moving as fast, and the exhaust fan might not move the heat fast enough to keep temps down. With no filter that air can move really fast and get the heat away from the bulbs quickly. 2. Separate systems means that the air that we use to keep our lights cool will not have smell because that system never uses air thats been in the grow room. Growers dont filter that air because they dont have to. Its a matter of efficiency in a sense.
+Nick Good question Nick! Thanks for asking. :) during winter I channel the air from my indoor garden up to the floor above and heat my hallway and bathroom - so I filter the air so my house doesn't smell like my garden. My wife doesn't relish the smell of tomatoes, unfortunately for her.
I know the positioning isn’t right for this but you can also use carbon filters to filter the incoming air to prevent mold spores, bugs, particles from getting into ur room/ten t
I know venting upward to work with the rising heat is important but what if restricting circumstances require you to duct down about six feet as soon as the air leaves the room? Theres about 8 feet of ducting inside the room. How bad is that and will it decrease ventilation enough to screw it all up? Also using six inch inline fan. Thanks for you help. Super instructional and I love it.
I created a set up almost exactly like this. I am having a serious problem because everything is sealed so well and the large fans are pushing so much air out of the house I am now driving air down my chimney into the house. This is especially bad for heating season. My heating and air-conditioning company said I must make a change immediately or our furnace won’t fire this fall. Please help thank you.
Hey am trying to vent the air with a rock and a oil can and some wires and I think am useing the keys from my 78 pick-up truck. How can that work? Cool let me know. P.s let me know how your vegetable garden comes out or what ever your growing. Cause that can't be weed
Will you use your home's AC to cool the air in the lung room and the mother room that's being used to cool your lights and intake? How cool should the intake and air going thru the lights be? Any general rule of thumb for that? Thanks in advance. Great setup and videos!
John Doe Thanks for your question John. I will not be cooling the air in my lung room. It's already a steady 64F because it's underground. As for air-cooled lights-be careful not to overcool as the lamps need to be HOT in order to generate the correct spectral distribution. Watch our video entitled "Does air-cooling your lamps decrease PAR output?" - think gentle breeze rather than Siberian hurricane!
Everest Fernandez ahhhh makes sense ! Didn't think about the basement. And thanks I appreciate it. I'm setting up a 4x8 tent. 6" phresh filter and 6" hurricane fan for intake. Same for the 2 air cooled hoods. And a 6" carbon filter and fan for exhaust.. hopefully that's not overkill as far as cfms go. Any input ? Thanks again !! This channel is super informative!
John Doe Hey John. It's only "overkill" if you are exchanging so much air as to lower relative humidity or temperature below optimal levels. Obviously this is largely dependent on your ambient environment. I'd say your tent requires a minimum of around 256 CFMs air exchange. A 6" hurricane is rated at 435 CFM, but your carbon filter will reduce this by 20% so you're looking at around 348 CFMs. I don't consider this too much because 256 is a minimum. Good luck and keep us posted! :)
I have a question. Why would you need a carbon filter if you are just growing chilli peppers in your growspace? I think the carbon filter is for some other plants :')
I wonder if I could put my 1800 watt Crees in one of those, it is hot as hell im a tent. Trying to work out something effective without getting bigger noisier in-line fans.
nevermind, i found the answer in a question below. haha. next question, you have a 4 in fan blowing in the lung room. i dont have a lung room, just a smaller sized grow box. would i need a small fan to push air through the air-cooled lights?
Don't know why you cut the ducting? A spigot to seal the gap between duct a plasterboard and just run a continuous length all the way to exit, eg. better air draw, less cutting a fiddling about with fittings. Also, when you cut ducting, run some silver foil tape around rim of cut and a few inches down the inside to reinforce and get a good join. ☺and use a pad saw for cutting plasterboard/dry line..if you hit a cable or pipe, you won't be happy 👍
So there's no 6" fan blowing through the hood vents? Does the heat just Ben out on its on? I'm pretty sure you'll need a 6" inline fan to extract the hot air right?
Val Wilder Good question Val! (And thanks for stopping by.) I'd have to get the calculator out as so much of this equipment has been built up over time (and many grows!) and my grow room keeps on evolving! It's a bit of an obsession, if truth be told-just ask my wife! Lol. If you want to include all my meters, gadgets, fans, lights, lamps, and systems-probably in the region of US$3-5K. I can sit down and give you a more detailed breakdown if you like. I might end up scaring myself and the wife may then have proper grounds for divorce on the basis of abject fiscal neglect! :)
Everest Fernandez lol I feel the same.. It's the most expensive hobby I've ever paid to ignore. I wish I had the wine cellar or just a basement period. I'm limited to a 5'X5'X7' grow tent right now but I'm using the titan kit like you are and I've gotta be easily 2000 in already.
Val Wilder I hear you Val. Unless you're growing super high value crops this really isn't about making money, but having fun, knowing where your food comes from, and giving yourself something to do over the winter! :)
Yogi Bear Hi Yogi B. Good question! My grow room is in my basement. The ducting goes up an old, disused staircase and out into my backyard. It's summer right now so that works great. In the winter I plan to divert the ducting so that it helps to heat my kitchen on the floor above. Happy to make a video showing the ducting plan if you like.
If inline air is going thru duct work to cool the lights and out of the room, why do you need an inline filter. That air isn't being circulating throughout the grow room, its coming in thru the bottom run thru the hooded lights and out thru the top of the room.
Hi Jim, thanks for your question. The Phresh intake filter removes dust and other particulates meaning nothing builds up inside the ducting, hoods and lamps so they are easier to maintain and keep clean.
You say you are going to divert the heat from the lights in the winter but what about the air being scrubbed through the filter and fan? That currently goes outside as well? What will you do with that in the winter?
Generosity Popo Good question G-thanks! I may channel that indoors to the upper floor too-however I'm a little wary of pumping too much moist air into my house during winter (think of all that transpiration!) but I like the idea of waking up to an oxygen rich living space! I'll keep you posted. First I need to purchase / create a neat way of changing the air flow direction without having to detach / re-attach ducting.
Wouldnt cold air wreck the globes or reduce the grow efficency? My room is too hot with a 1000 watt its only 4 x 4 even with a hyper fan and 8 inch carbon filter its way too hot, 34 degrees when its only 25 outside! So I dont know what i can do in summer.. Maybe dropping to 600 wats may help the room be growable in summer, although i dont know if that will drop the heat enough.
Hi PC, I would recommend dropping to a 600W or 750W system and consider investing in some active air cooling so you can keep growing through the summer.
Thanks, shouldnt the fan n filter setup be cooling my room? Maybe it is and it would be worse without it. Problem last winter was it was getting to 9 degrees celcius at night. What annoys me about needing the carbon filter, (used to live by myself and didnt have to have it then) is you are limited as to what you can control, no point using Co2 as it will all just get sucked straight out, and im wondering if an oil heater might help at night, or will the fan suck most of that out? I cant use an air con as no access to exit points, (Carbon goes into roof) but im wondering if the cool lights you have above will save me? Can you just extract the heat out of the light into roof or do i really need a cool air inlet for it to work? Thanks for the Advice love this channel mate.
Hey man should I set up my intake and outake on separate sides of my room? Would it be ok if one is coming in throught the bottom and one at the top? And yes im gonna have oscillating fans for air circulation. Thx
+KillerShootin 69 sure - ideally your extract should be high up and your input should be at bay height, in between plants and canopy. I take and out should be at opposite sides too, you're right.
Jesse Langdon Thanks Jesse! I had to build a sort of 'room within a room' using a metal framework, water supply and plasterboard plus install two new dedicated electrical circuits. That was US$2K gone right there! The equipment minus lights was easily another US$3K-some of it I had already (fans, pumps etc)-it's best to start off small and gradually grow :-) be careful as it tends to take over your life! :) hehehehe. No, seriously-the fresh herbs and produce for my kitchen, as well as something 'summery' to do over the winter is well worth the investment! I've got so much planned for the next year so make sure you're subbed! :) Thanks!
+Miquiel Ward Hi Miquiel, thanks for your question. It's worth noting that alternative arrangements are possible. You could use a length of ducting between your air cooled hood and the duct fan instead and locate the fan elsewhere. Many growers take this approach so that their lighting fixture is not unevenly weighted with a fan attached at one end. However, if your preferred arrangement is to connect the fan directly to the hood, attach it so that it blows through the fixture, use duct tape and a noise reducing clamp, and then fixture hangers to take the weight of the fan so it does not pull down on your fixture and is more secure.
+Caleb Deslich You must have secret cameras in my grow room Caleb. I was just noticing the other day how I need to improve my door's seal as I'm dragging in quite a lot of unfiltered air right now through the crack between the door and the frame-not good. I'll get my handyman friend over and make a video about sealing it up-on the list for 2016!
Micheal Jordan Hi Michael. Thanks for your question. Air is constantly exchanged in my indoor garden, whether it is lights on (daytime) or lights off (nighttime). As such the ventilation fan is on permanently, although the speed / power of the fan is determined by a fan speed controller linked to a thermostat. Check out the Mercury series or Spartan fan speed controller by Titan Controls-alternatively, take a look at the Zephyr 1.
I prefer white these days because it looks a lot cleaner and nicer, plus there's an argument that it absorbs less heat. However I have to make do with what I can source easily.
Keep that speed talk going we need all your information
I've been following along thinking you was gunna be growimg bud 😂😂
Did you see my latest video?
I like the videos. Simple and to the point! 👍
Thanks Trace. Hope you're subbed.
Great video! Thanks
Well explained and my grow room thanks u
beautiful job man!
I done exactly same as you and temp still same
can you tell me why people don't suck the air through the filter through the light and outside thank you very much I really like your Channel

+Nick Good question Nick! Thanks for asking. :) during winter I channel the air from my indoor garden up to the floor above and heat my hallway and bathroom - so I filter the air so my house doesn't smell like my garden. My wife doesn't relish the smell of tomatoes, unfortunately for her.

Walter Miranda I wouldn't worry Walter. An exhaust fan and ducting will send your air in any direction you wish. :)
Should use a gyprock saw for the holes.

Would using insulated ducting on the rest of your ventilation cut down on fan noise? If so, is it ideal if you don't mind paying the extra money?
Cant you buy cool lights that dont have an air inlet they just have an outlet to let some of the heat generated from light go out of the room??
Is there a fan pushing/drawing air through the ducting of the air-cooled lights?
nevermind, i found the answer in a question below. haha.
next question, you have a 4 in fan blowing in the lung room.
i dont have a lung room, just a smaller sized grow box. would i need a small fan to push air through the air-cooled lights?

Fritter rolls mmmmmmm
So there's no 6" fan blowing through the hood vents? Does the heat just Ben out on its on? I'm pretty sure you'll need a 6" inline fan to extract the hot air right?
Hey Eman. There IS a 6" fan blowing but it's not attached directly to the light. It's located in my adjacent lung room connected to an intake filter.
It's really nice how you have this all set up.. What was your ballpark final budget when all was said and done?
Val Wilder Good question Val! (And thanks for stopping by.) I'd have to get the calculator out as so much of this equipment has been built up over time (and many grows!) and my grow room keeps on evolving!

wow. i didn't think i would get a response from ya. thx...
another question?
so im guessing no co2 system? since its not sealed
the duct should be white?
I prefer white these days because it looks a lot cleaner and nicer, plus there's an argument that it absorbs less heat. However I have to make do with what I can source easily.
Schlong
Glad you noticed :)
I was out when you referred to the ducting as a schlong. way too enthusiastic bud...
Cheech, can't apologize enough. :)
Jesus that sealer hahaha have you never heard of silicon sealent
