FAE tek.+Fc soon to be glovebox
#7943802 - 01/28/08 02:09 AM (16 years, 5 days ago) |

Usually I have a filtered air pump running into the Fc, and a hole with a HEPA filter for the air to go out. But the pump burnt out, so I got a plastic tub and cut out a hole in the top and put a fan on it. Then I put a smaller 6 by 4 tub on the side with a filter in the end so I can "plug' it into the Fc If I put a fan ón the other side sucking the air out of the Fc without a filter somehow around it would contams get in? Or would the fan keep them out along with the positive air flow?
Ill post some pics tomorrow night

The only risk is that air will flow the other way through your fan. This could only happen if your hepa filter clogged and the fan created substantial negative pressure. This is important you seam to think it's positive pressure but it's actually a vaccuume in there with the inflow from the negative pressure being drawn through the hepa filter.
I might recommend putting some form of hood around the fan to keep contams from getting near it. How fast is the fan running and how's your Humidity? The problem is not likely significant since many terrarium techs with perlite instruct people to make uncovered holes in the terrarium and let it sit. Colonized cakes are in little danger of becoming infected as I (a noob) understand it from normal gas exchange though adding a fan to the whole thing makes it kinda blurry.
<edit> never mind I thought the airflow dynamic was based on suction.

Aye, from what I (also a noob) have heard and experienced, fully colonized cakes are very hearty and it takes a bit of neglect to contaminate one.
For example... RR (RogerRabbit) grabs em with his bare hands and tosses em around in his PF Tex style grow video (even drops one into the sink!) and then places em into a FC with a bazillion holes, absent of any filters. I'm pretty sure he knows what he's doing! 
I wouldn't worry too much about the contams unless you have a very dusty old house, musty/humid air with no AC or tend to let food/dishes lay around till they change colors.
Now, it IS still possible for even the cleanest person to end up with a contaminated cake. So if you feel more comfortable with the filters, have at it. Either way, don't stress too much! 
Since you have quite a few posts and you're using an advanced setup, I'd assume you know most of this already. To actually answer your specific question, contams can't get in at all as long as your seals are air tight, your intake has a hepa filter and the air flow is positive... which it sounds like it is. I'd be really interested in seeing some of those pics!
Enjoy the process and Good Luck!

Moving air like that will dry out your project, IF the fan is strong enough to push through that filter. However, doing so is like putting roller skates on an elephant. It isn't likely to have the desired effect. RR

Thats too much lol. Think fish tank pump for that tub. It looks neato- but its just something that says "I didn't do my homework and look how much time I wasted" You wont have any water left in your substrates to give you any fruit, if they don't travel to contam city.
Honestly... Are you having that bad of FAE problems with your grows?

The fan just barely pushes the air through the filter. It almost puts a flame out but not quite. I had a smaller fan but it didn't do shit. So how's that gonna dry it out?

Well, that's one hell of a setup
The fact that that huge fan is barely moving air can't be good for the fan motor.
But more importantly, you got a lot more goin on with that box than you need. Just a couple holes filled with polyfill (or nothing at all) would provide sufficient gas exchange. You don't need to worry much about contams on fully colonized substrate.
Just put it under a light and mist 2-3 times a day and you'll have something to show for it most likely.
If i could see that rig in person, I'd know more to tell ya but analyzing Frankenstein from a photo is... well, it's hard to really tell ya what to do with it. My ultimate advice is: buy another tub, search these forums for a couple hours. Search for "fruiting chamber" with the forum search feature. There's TONS of pictorial guides that will give you very reliable results.

After it comes out the filter, or within the chamber? Moving that much air around inside your terrarium is only going to dry out your substrate. This seriously is the definition of overkill. Like Civ said... think fish tank pump.

I think its overkill myself, also that looks really ghetto lol you got tap streched out holding shit on LOL Also why in the world would you put the filter on there to filter the air being pushed out ??? That makes little to no sense at all, the dirty air will be filtered inside the FC before it leaves LOL

filtered air is being pushed into the Fc. I was thinking about filtering the outtake because it seems like air goes both ways with a fan, just a lot stronger the way its supposed to be.
the tape was there for support while the caulk dried. And a little on the fan to keep air from escaping.

Yeah, I never said that. But you are hilarious.
Sorry I misunderstood your overly complicated FC set-up. My bad. Let me just go over the advice you've been given...

Also, you make no mention of how you are going to maintain high RH levels. Maybe you should rig a cool-mist up to that bad boy. Anyway, I think the general consensus here is you don't need all that nonsense. Go buy a new fish tank pump. One that pushes 2-3x the volume of your FC per hour. Peace.

lmfao RR's analogy for the day haha
I could imagine RR being a couples therapist. You brining chlamydia home from your trip in guam is like me boning your wife last weekend while you were on your trip.
but yeah he's right my friend had a small ass chipset fan running off of a old psu with a resistor to slow down the speed so it's at that point where you can see it spinning instead of a blurr and yeah his cakes dried out after a week he had to rebuild his terrarium and used the cakes as spawn.

Everyone does relize that is not the fruiting chamber??? The filter will go into the Fc and the air will barly move in the Fc. Just enough to keep a positive flow. Ill post pics of the whole set up soon.

Jesus Christ do you think I seriously have a huge fan on top of my fruiting chamber?
Its basicly the same as puting a air pump in a box with a HEPA filter in the lid so its sucking clean air except mine has a fan and is pushing clean air

Ok ok, now it's starting to make sense, sorta.
So that thunder dome is the assembly that forces fresh air into your FC.
Well, then i must say that it is a very innovative, imaginative and intimidating setup. And it looks like it would work too. I'd still say it's overkill since you don't really need filtered air flowing into your FC (unless you have some fairly unclean habits) but at least now i can say that i believe the contraption would do it's job at keeping contams out of the FC and supplying FAE. This would assume that your seal to the FC was airtight and there aren't any leaks in the duct tape. The fact that it barely moves a candle flame sounds like a fairly good amount of air flow.
The real test is to hook that sucka up and see what happens. I have never seen anything quite like it and I am extremely interested in seeing how it plays out.
Do you plan on posting a grow log? I would love to see how it works!!
Don't get discouraged if we poke a lil fun! You gotta admit, that thing won't win any awards for finesse but it will definitely catch the eye!

this is working well for me .. get an electric inflater ( for air mattresses and such ) and u can do it 2 diff ways .. plug the nozzle end into your terrarium with a coffee filter or 2 or spread of polyfil over the out-hole .. or seat the intake end in a larger hole in the terrarium and allow it to suck the stale stuff out .. both would need a few polyfilled vent areas in the wall of the terrarium to alow movement of either gas .. put it all on a timed socket extension and u never have to lift a finger ..

Yea as soon as I'm done I'm gonna post the whole tek and a grow log. I swear this thing started out way smaller lmao the 'female port' was all it was at first. I've always been really contam paranoid. Which has worked out well so far.

Ok I finally got pictures of the rest of it. The only thing I'm missing right now is the cool mist I'm gonna use.




I have timers to regulate humidity and fae. I'm also going to make it a flow hood glove box, once I grab some gloves. I just got my spores which I ordered on Christmas, I ordered 10 cc's of jxmi huautla, Nepal chitwan, and pes Hawaiian. But got 20 cc's of each plus some pale oysters which I wanna trade if anyone wants. I'm gonna knock my bags and jars up tomorrow and am gonna make a grow-tek log with pictures

is this unit just the air filter or the FC? are those fans blowing out of the FC or into it? I still am confused.

Ok. The blue box has the fan on the lid with a timer pushing air through that black hepa filter
 The small fan on the side is also on a timer to go with the big one on the fan box. It pulls air out of the Fc. And will be used with the flow hood glove box when I put them in.
 Before my myc is fully colinized ill have a cool mist running in the clear Fc.

Well I like it. Its going to work as my Fc, flowhood, and incubater You guys will see once I have massive shroomies. I gotta assload of great hpoo, plenty of straw. I keep my incubater at 84 degrees, my Fc at 73 and 95 % humidity.

Yea it's a nice setup though I don't see why the fans on the fruiting chamber are there. Shouldn't positive flow from the hepa box make it unnecessary?
