no contams in winter comtams in summer !

i been vary successful growing with coir and verm in winter but when last spring came and it got warmer out i went from basically contamination free to loosing %50 to %70 of my trays . i thought it was from an increase in the air born particles in the warmer season but some guys over at the growery insist that it was my bad sterile technique,my thought was i could use an air purifier to combat the problem but being the guys over at the growery said differently so i would like to get more opinions on the issue .
i work in a still air box in the bathroom i fog it before i do my work ,i wipe my spawn jar with alcohol before i work with it and i have never had a contamination problem in the winter that's what gives me the idea that it a combination of air born particles and the heat from the warmer season !
what do you guys think ! please have experience ,thanks !

it's all an illusion, ge thte air still and the sab wet and your stuff sanitized/sterilized

Summer contamination [Re: dmtcorey]

Your having contamination issues with your bulk substrate, not spawn right?
Knowing what kind of contamination and when in the process would be helpful.
I think what CRONICR is saying about having stuff wet. In your still air box if you sop some soapy water** on the walls and floor* (puddly wet) that wet surface is like a trap. Anything in the air that blows into the soapy water gets stuck there like a rat in a glue trap, cleaning your air like a filter. Another layer of protection as your movements stir up the air.
*if you sop water on the ceiling of the SAB then it could drip into your work. **Soapy water is stickier than plain water.
I think the weakness lies with pasteurization. Being that your contamination rate is so high, to me suggest a procedural problem. The strength of bulk is that it's less susceptible to contams because of friendly bacteria. Maybe you are killing off these good bacterias, sterilizing your substrate in some parts. If I was dealing with your problem I would check my pasteurization process to make sure I was staying in the cool 140-160F range for the full one hour, where beneficial bacteria are preserved.
But maybe the PH is running too acidic, something new could be at work there.
Another possibility is that your substrate is too wet, which is a factor that would contaminate more readily in warmer climate opposed to cooler. You can shoot for barely field capacity, maybe just under. Then when you reach 100% colonization if you want to dunk you can, probably not really necessary but its an option thats better than an overly wet substrate from the start. Also with that note: if your colonizing okay getting contams after the first flush, then try lowering your RH to the low 90's or even as low as 88% trying to keep the surface from becoming overly moist to foster molds. The time frame that its good to have high surface humidity is when your trying to form a good pin set. (Wax paper, bubble wrap etc) After you have a pin set, super high surface humidity is not that important anymore, mushrooms have started -just need to nurture them into maturity.
As a last resort you can at least salt* your wounds, and maybe get another flush out of it.
*Salting: if there's mold (or another contamination) scoop it out and put salt in the void.
good luck

thanks for taking the time to write ,
ya my problem was with the bulk ,i would be lucky to get one flush let alone 2 but the contamination i got was mostly green mold and i think there was the odd bubbly white looking contam to .
i see what you guys mean now about the wet in the sab now ,what i do is the jars go straight to the sab from the pc and i would wipe my spawn jar down and put it in there to and mist inside with bleach so yes i would get everything nice and wet and i would make sure i don't get the dripping on to my work !
seems like the pasteurization could be the loop hole ,usually i take my huge pot of boiling water and mix it to the bulk right away with no time to cool then quickly cover and let site till cool ,im pretty good when it comes to the moisture content of the bulk i rather it colonize a bit faster to avoid contamination and i add about 1tbs of gypsum to the boiling water before i add it to the bulk maybe i will add a couple tbs,s of dolomite lime to make things more alkaline 
thanks man !

not that it really should matter if your sterile technique is up to par and you're using a SAB. but the bathroom is the last place on earth I would put my SAB let alone try running a fan in the same room as a SAB.

i think running a fan in the same room is defeating the purpose of the still air box,im going to build a flow hood for the spring but i had used the bathroom so i can fog the room !

don't try to fog or clean a room it's entirely pointless. you cant sanitize a room let alone come close to sterilizing it. just the inside of your box worry about that space. and don't use fog use a spraybottle with water and a drop of soap, we're not trying to sanitize or sterilize anything in a SAB in the first place so don't try to, bad logic.

box on table, spray, wait a few seconds, go to work.

end up with lots of success.

I have some ideas I would like some opinions on guys ,
first idea ,would there be any benefit in using my 8x8 grow tent in a bedroom and have a air purifier in the tent and one out of the tent to try and combat air born particle in the summer months ?
second idea ,maybe running a ozone generator for 15 mins a day would be a good option to combat my problem ?
and being im going to be investing in a flow hood soon where is the best place to set up a work station ,inside the bedroom that will contain the project ,shoot me you ideas and views guys .
thanks,

personally I don't think you should go overboard with all that stuff. Yes its good and all but I think you should monitor the small things instead of using a canon to kill a mouse and miss the mouse
Do you have a edit ...digital meat thermometer http://www.amazon.com/Taylor-1470-Digital-Cooking-Thermometer/dp/B00004XSC5 for pasteurization? DO you have a still air box?
Something like that^^^

no eh ..lol I don't have a temp gauge no but I will grab a meat thermometer ,I had been adding my boiling water to the dry bulk right away so the water temps may be to high like you guys mentioned ,I do have a sab but plan on getting a flow hood soon.

that's your problem right there. What you've done is created a "bacterial bloom".
I guarantee if you monitor that temp like a fucking hawk. Things will turn around. YOu can fix this with a 15 dollar purchase. And don't let those temps get higher than 170

i know this thread is a bit long gone but I would like to post an update and thank you guys once again ,
so I made some changes and those changes were .. ~I got the meat thermometer for making my bulk sub and heat water to no more then 180. ~let my grains sit for 24 hours before pc,ing ~and pc for 1.40 hours instead of 1 hour ~added gypsing well hydrating the grains.
everything is right on track with no contamination
