noob pf jar question
    #5907512 - 07/28/06 12:07 AM (17 years, 8 months ago)

after inoculation of the jars should i put micropore tape on the injection points? would this help keep out potential contaminates along with the verm layer or just help with gas exchange?

no

the verm layer is fine

micropore could suffocate the jars
when used in conjunction with a dry verm layer.

1) Yes, you should put micropore tape over the injection holes. B) Yes it will assist in guarding against contams, probably more so than the verm layer. IMO by the time something is in/on your verm layer, it's already in your jar, so you're already almost assuredly fucked, if that makes any sense...maybe my POV is off, I dunno. 7) Gas exchange without micropore is actually (in theory, mind you, I'm no physicist) more efficient, but you're not that concerned with letting them "breathe" so much as you are letting them "exhale" so to speak. But you're not using it for gas exchange, per se...you're using it for SAFE gas exchange. Make sense?

Peace.

well if you use micropore,

why not just forget the verm layer?

I've heard plenty of stories of stalled jars with micropore tape over the holes.

what do you hear for advice?

remove the micropore tape!
let the jar breathe a bit,
flip it over if needed,
crack the lid if needed.

I don't use cakes, I use grain.
and I use micropore to cover the hole I make in the tyvek.
it works very well for that.

I grow a lot of cakes, and all the micropore tape will do is slow down colonization. I can tell you that from experience. The dry vermic. layer is all you need. I agree with Monstermitch 100% on this. And colonization is a window of opportunity. Why slow it down by choking jars with unnecessary tape?

I'm with MLB on this one.. I have made tons of jars and i never use tape and all my jars have been successful.. Sometimes i will put put paper towel peices and screw them over the lid to give some extra filtration while still allowing for gas exchange.. So far i haven't lost one jar to contams and every one that has started has finished right along with the rest..

I'm new at this but in my current grow I used a packed vermiculite layer and professional grade masking tape (original PF Tek instructions) and my cakes were fully colonized in 16 days. No contams and MAD fast growth. I birthed then on day 16. Hell, I even used aluminum foil on top of all that stuff - my first grow gave me contams so I was paranoid and probably went overboard.

I'm not saying you should do this. I just know that using tape won't cause a problem. The more important factors seem to be correct balance of substrate ingedients, darkness for incubation, and 82 - 86 degree temperature. I used a glove box for inoculation too and a PC for sterilization. Under those conditions, my cakes just took off.

So the jars that took 16 days to colonize were contaminated, or was that a different batch?

using tape can cause a problem. masking tape is likely breathable to an extent, so it worked for you. try using electrical tape or a little piece of duct tape, they will go slow, and stop dead in their tracks part way through.

i've use micropore myself. but i've used several different kinds of micropore. if using the 'nexcare gentle paper tape' variety you can leave it on the whole time. i've seen colonization in 10 days with this. you won't get faster than that, even with the holes uncovered. other kinds of micropore tape can be thicker and slow things down.

the easiest thing to do is leave them totally uncovered, with a loosely fitting aluminum foil lid. (just reuse the foil you used to cover them when sterilizing.) this is the best of all worlds - you get gas exchange, you've got a dust cover, and best yet, there's no tedious work of cutting up pieces of tape, and cleaning them up later when its time to re-use the jars.

The jars that took 16 days to colonize were clean and free of contamination.

I picked up some micropore gentle tape the other day thinking I would try it out. Does it hold up through PCing?

I think the micropore tape would slow things down.

I have had to use coffee filters with a rubber band(to hold them on) to help protect from fruit flies. This didn't slow down colonization.
