Also, for this small of a scale, wouldn't this work :??: Not suggesting it would work as good as a plenum or anything. ;) just seen this and thought it might work for this size of grow http://out-grow.com/cultivation-equipment-c-1/tropic-aire-humidifier-p-140.html
Still mo plenum. You can build a mini plenum for 50 bucks or a precise one for about a bill. Mine will perform as little as 1 replacement per hour to 8, humidity from 80 to 100 in one percent increments to as many as three hundred cubic feet, depending on excange rates. I only have to service it every three days
you don't need that capacity unless you are doing home grows of eatables like oysters or shaggies. There is a picture of my plenum on this site somewhere. You can even control temps that way but I prefer to have a large differential between my substrate and the surrounding atmosphere.

that is a laminar air flow hood, while it is extremely handy for sterile with, it is not what I am talking about.
oh ok. sorry bout that.. I found a plenum after I had signed off last night.

i love that mini humidifier. i think it would be perfect for a small grow.
Yeah, thats what I went with.. Well this --> http://www.amazon.com/gp/product/B0019IJXD2/ref=oh_details_o03_s00_i00?ie=UTF8&psc=1


and also purchased a high powered air pump to make sure the terrain has good air flow/exchange on a higher lps. http://www.amazon.com/Hydrofarm-AAPA45L-20-Watt-Commercial-Outlets/dp/B002JPRNOU/ref=sr_1_fkmr0_1?s=pet-supplies&ie=UTF8&qid=1394125052&sr=1-1-fkmr0&keywords=high+lps+air+pump

What are you making? You can make a SGFC or Monotub very cheap.

You either have to calculate the free space in your fruiting chamber or have variable pump speed. You don't want more than three or four air exchanges in your box. Even at a humidity of 100 percent, high air movement will dry your fruit before it grows properly or stunt them just after they pin.

Figure the free space of your chamber and the cfm of your pump. i am not sure that your humidifier is variable either, but that may be enough for you.

There are a few ways to make a decent plenum. Get yourself a couple of those ultrasonic misters, put them in a bowl in a sealed or semisealed bin with an aquarium pump. Make a hole in the bin with a hole drill, save the disk and attach it to the side of the hole so that you can swing it or slide it open or closed - like a flue.


A better way is to get a humidifier at Wallmart, and put THAT, along with an air pump in the bin, run the tubes to your closed fruiting chamber (NO holes), so that you create a slight positive pressure - driving out contminations and preconditioning the air at whatever humidity you want. The humidifier has a tank on it that should last you several days. that "fanning" simply sends spores of whathave you all over your crop, over and over again.


I just looked at your pump - 45 liters per minute? You want an exchange rate of 1 to 4 per hour. If your bin is 45 liters, then you will be doing 60 exchanges an hour. (if I read that pump right) I doubt you have a bin big enough for that. Better hope you use a gang of valves. Oh, and you will have another problem - that pump is going to get hot. It seems as though you are pumping ambient air through your humidifyer so you can leave the unit outside (no plenum), but you are going to be driving heated air through your little humidifier and will lose control over the temperature in your chamber. Furthermore, if you are driving heavily humidified warm air into your chamber, the temperature will cause the water to condense on the sides. You want to do everything you can to avoid condensation, it is the perfect way to not only catch foreign spores but spread them to your grow AND supersaturate bits of your growing surface, just right for those spores to germinate.

Cool deal.
  • , run the tubes to your closed fruiting chamber (NO holes), so that you create a slight positive pressure - driving out contamination and preconditioning the air at whatever humidity you want. The humidifier has a tank on it that should last you several days.

    that's what I was thinking. Some way to "push" all the old "possible contaminates out". I was thinking about putting a small valve towards the bottom for the air exchange. :??: The box is one of caligrow kits small ones. I was just thinking about getting one of those huge ass totes from wal-mart. Should work dont you think :??:​

If you really want to do this right, stay totaly modular, but that won't work for you now. That pump, if it is in liters per minute is far too big in my opinion. If you get a bin, try to get the darkest one you can. Then you can either cut a "skylite" in the top or mount a small flurescent in the lid and put that on a timer. You are doing cakes, so it isn't as important but should you ever go larger, it's nice to have total control over your light as well. Those blue bins are HORRIBLE as they tend to let the exact specrum of light through to your crop regardless of whether you want it or not.

And in case you are wondering - those pumps will ALL pump 100 percent humid air for years and years with no harm to the pump.

Well, I had purchased for use on other project to, so hopefully using 3 or 4 of the air sites will cut down on the flow a little. Using it more so for air exchange. And the mini reptile fogger for the humidity. Yeah, lol thats just about all they have (wal mart) is those huge ass totes (blue) in color. Maybe I could find a "black one". Either that or just get 2 and drop one into the other..

Here's a few pictures. Looks as if another strain is showing sings of colonization. Mexican jar#1 -> PIC_0856.jpg Signs of colonization (Mexican jar#1) ->PIC_0857.jpg Mexican jar#1 -> PIC_0858.jpg Golden teacher jar#2 -->PIC_0859.jpg signs of colonization -> PIC_0860.jpg

Home depot. I don't think you will be able to use but one line with the humidifier you are getting. So you get it? NO aparatus is in your fruiting chamber but a tube? I have found that it is wise to put tiny holes along the length of the tube after it enters your chamber, and blocking the end of the tube, this creates a more even flow across your entire bed.

Yup.. got it. ;) air line in box, not machine. lol Thanks.. I found a dark "brown" tote in the closet. Wife is going to kick my ass 4 using it, has all her quilts and stuff in it. lol Oh well. Looks like its going to go to "better" use. lol

The last few pages blew my mind a bit. Glad to see some progress, sorry about the first jar. Hopefully the one and only. Cant wait to see your fruiting chamber,

Yeah, well they "said" they where pre sterilized, however with it becoming contaminated all the way near that 1 jars bottom, I don't see how that jar was sterilized. The others haven't showed any signs of contamination. The 4 new jars I just made (Popcorn & WBS) have already started showing signs of colonization, not 1 sign of contamination as of today and they aren't even a week old. Very small fuzz(colonization) starting on separate pieces of Popcorn.
Not only that, but if those were presterilized, then they didn't do a very good job. Highly unlikely that the errant spore lighted that far down in the jar from a ban innoculation.

I never trust when they say its sterile. i always run boiling water through mine when im gonna can. so that is best practice Dank. see germs and bacteria cant live above 180 degrees F. so if you boil water and submerge them in it them remove and sit upside down on paper towel then load and use it you will be allot better off.

There's plenty that can live in 180F water. I don't know how well they do in conditions favorable to mushies but there are absolutely things that can survive that. Actually sterilizing things is pretty tough. There's a reason pressure cookers are really the standard. Boiling at 15psi for an extended period of time is probably the easiest way to be sure. But it's getting contaminated by your environment as soon as you open it.
